Soccer, even in its most rudimentary form of kicking and chasing a ball, offers a fun and effective form of physical activity. Not coincidentally, to perform at their best in a competitive game, young players must be physically fit. More and more coaches are beginning to realise that conditioning in children is not contraindicated simply because of their age. In fact, planned properly, a fitness program started in the early years can prevent injuries, prolong a player’s career and help that player to reach a higher potential when they mature fully. When asked directly, many coaches will say that skill and technical ability is more important than physical fitness. Yet the same coaches regularly pick the tallest, strongest and fastest players first, leaving the late developers to warm the substitutes bench. While they may or may not admit it openly, they know that physical prowess usually conquers technique. Consequently, many overzealous parents and coaches subject their children to a demanding training regimen in the hope that improved strength, speed and stamina will make them better players. Some coaches and parents are even aware that sport-specific drills (exercises that mimic the demands and movement patterns in soccer) create greater results than general fitness training alone. They devise a soccer-specific fitness plan and sure enough, results are forthcoming. Their child, or their team, improves significantly in a short space of time. www.sport-fitness-advisor.com !4 Fit for Soccer - Junior Players Everyone is happy, for a while, but the physical and mental stresses of intense sport-specific training soon begin to takes their toll on the young player. Too much, too soon invariably leads to all manner of physiological and psychological problems. SPORT-SPECIFIC VS MULTILATERAL DEVELOPMENT If there is one principle stressed in this book more than any other it is this: A long-term, patient approach to a child’s athletic development will produce a happier, healthier and more successful sporting career. It may sound like common sense and it may sound like a philosophy that is easily implemented. However, sacrificing the short-term and immediate success that specialised training can offer, in favour of long-term, gradual improvement proves very difficult for most coaches and parents. Multilateral or multi-skill development is the process of developing a variety of fundamental and general skills that allow children or youths to become good overall athletes. Not only does it prevent too much stress on joints and growing bones, it builds a solid foundation on which specific training can be built in the mid to late teenage years. A study performed by Harre (1982) compared sport-specific training versus multilateral training in 9–12 year old children. The sport-specific group completed exercises that closely www.sport-fitness-advisor.com !5 Fit for Soccer - Junior Players mirrored the demands of the sport while the multilateral group took part in a variety of sports and general fitness training. Results showed that the sport-specific group peaked at age 15-16, while the multilateral group peaked at 18 or older, when they were physically mature. Significantly, the multilateral group consequently had a higher peak - in other words they were better! The sport-specific group suffered more injuries, were more inconsistent and dropped out of the sport at an earlier age (often before 18). However, the sport-specific group also improved at a faster rate. Until the age of 15 or 16 when the multilateral group began to specialise, the sport-specific group were physically more capable. You can see then why it’s tempting to opt for intense sportspecific training even though immediate gains may be to the detriment of ultimate potential. The results are backed up by other researchers including Nagorni (1978) who studied young Soviet athletes over their careers. This book has been designed to support parents and coaches who want to help the young players under their care reach their full potential. It will show you how to develop a long-term plan that will allow young soccer players to peak at the right time, whilst enjoying a steady progression. With this patient approach, should those players ever wish to pursue the game to a high level, they will have the best foundation to support them to that end. And should their ultimate choice be another sport entirely, they are more like to be an “all-round athletes” who excels at a multitude of sports. www.sport-fitness-advisor.com !6 Fit for Soccer - Junior Players SECTION 1 TRAINING PRINCIPLES FOR JUNIOR PLAYERS ports fitness advisor www.sport-fitness-advisor.com !7 Fit for Soccer - Junior Players At every level of the game and at any age, soccer players must follow a well-planned coaching program to be successful. There are innumerable coaching books, DVDs, camps and programs that focus solely on skill development and acquisition. Some address tactics and positional play but ew give any attention to fitness and conditioning. Those that do, rarely address the needs of children. They focus instead on the more well-researched adult training principles. Children are not mini adults however, and they cannot simply follow a watered down version of an adult conditioning program. One of the most important training principles in sports conditioning for adults athletes is specificity. This principle states that exercises should mirror the demands in soccer. For example, soccer is an intermittent sport with plenty of short high-intensity running, twisting and turning, separated by minimal rest periods. A training plan made up of repeated sprinting over short distances in different directions is more effective than running laps of a track at a steady pace for example. Even in children, this sport-specific approach will elicit greater results than general, or multilateral training. Remember the bigger picture however! A slower, more gradual program that builds a general but solid foundation will produce a superior athlete and soccer player in the end. Think of the hare and the tortoise - slow and steady wins the day. This chapter outlines the general principles important in conditioning for children. These principles apply to all forms of conditioning such as strength, speed, endurance and flexibility. Each of those components is covered in detail in subsequent chapters. www.sport-fitness-advisor.com !8 Fit for Soccer - Junior Players Conditioning principles change as the player matures physically and mentally. As a guideline, this book splits soccer players into three classifications: • Pre-puberty (approximately 8 – 11 year olds) • Puberty (approximately 11 – 15 year olds) • Post-puberty (approximately 15 – 18 year olds) Once an athlete reaches physical maturity, as long as they have developed a solid foundation they can move on to high performance training found in the senior version of Fit For Soccer. Don’t worry if some of the terms in these general guidelines seem unfamiliar. They will be explained in subsequent chapters. Chronological & Biological Age For the purposes of this book, three age ranges have been chosen that roughly relate to pre-puberty (8-11), puberty (11-15) and post-puberty (15-18). However, it’s important to remember that children develop at different rates and their biological age may be different to others who are the same chronological age. For example, a soccer team consisting of 14 year olds can vary in biological age considerably. Early developers may have a biological age of 16 compared to late developers who have a biological age of 12. Coaches and parents should bear this in mind when developing a conditioning program. Biological age should be used to administer appropriate exercises. www.sport-fitness-advisor.com !9 Fit for Soccer - Junior Players PRE-PUBERTY (8-11 YEAR OLDS) From a developmental point of view, children as young as 8 can begin to incorporate activities designed to improve their fitness. However, at this stage it will bear little resemblance to the intense and highly structured training programs of mature players. Multilateral development, as opposed to sport-specific development, is much more important during this stage than at any other. Recall that multilateral development refers to general fitness and skill development that is not specific to soccer. From a practical coaching point of view this means including activities in a training session that might have little relevance to a soccer game. At this age, basic skills that can be applied to many different sports and activities should predominate – such as jumping, running, catching, throwing, tumbling and balancing etc. Many coaches make the mistake of using only kicking and dribbling activities and skills with a ball at the child’s feet - after all they are training to play soccer. But this is the short-sighted, sportspecific training model which is less likely to produce outstanding soccer players in the long-term. A multilateral soccer coaching session could also include throwing activities in the style of rugby or basketball or balancing on low benches, on one leg or as part of a group on a small mat for example. Here are some more general guidelines for conditioning children in this age group: www.sport-fitness-advisor.com !10 Fit for Soccer - Junior Players • Training sessions should be low intensity using only • • • • • • bodyweight or some very light medicine balls and dumbbells. Games should maximise participation. Large groups should be split up to minimise periods of inactivity. Encourage participation in other sports and other modes of exercise. Swimming helps to develop the cardiorespiratory system without placing undue strain on growing joints. Emphasise and reward participation over winning. Children have a low tolerance to lactic acid so avoid repeated intense activities that lead to exhaustion. Conditioning activities can take place during group soccer coaching sessions, separately at home or ideally both. Conditioning should focus on developing aerobic endurance, balance, co-ordination, basic strength and flexibility. This will be examined in detail in subsequent chapters. PUBERTY (11-15 YEAR OLDS) During adolescence physical capacity increases rapidly. Early developers will have a significant advantage over later developers at this stage, although a rapid growth spurt may lead to a decrease in co-ordination. Although more soccer-specific conditioning is introduced (particularly towards the end of this age group), training should still emphasise multilateral skills. Players are still vulnerable to injury and as bones develop more rapidly than muscle, stresstype injuries are common. Here are the general conditioning guidelines for soccer players in this age group: www.sport-fitness-advisor.com !11 Fit for Soccer - Junior Players • Continue to encourage participation in other sports and • • • • • • • • • modes of exercise. Emphasise flexibility, co-ordination and balance exercises. Introduce more structured strength training focusing on the core muscles – hips, abdominal region, low back etc., as well as major muscle groups of the extremities such as shoulders, arms and legs. Exercises should continue to use bodyweight or light equipment such as dumbbells, medicine balls and body bars. Continue to improve general aerobic endurance. During adolescence the body becomes more able to cope with lactic acid. Initiate some moderate anaerobic work in the form of short sprints with minimal rest periods. Avoid intense plyometric exercises (jump training) as these can place a high stress on vulnerable joints. Basic speed and quickness drills can be introduced but should not lead to fatigue. They should aim to develop motor coordination rather than power and acceleration. Simple mental training exercises can be introduced such as goal setting and visualisation. Introduce more competitive situations but continue to deemphasise winning in favour of participation. POST-PUBERTY (15-18 YEAR OLDS) By the mid to late teens, soccer players should have ideally developed a solid base of athleticism. They can now begin to adopt a soccer-specific program designed to mimic the unique demands of the game. www.sport-fitness-advisor.com !12 Fit for Soccer - Junior Players The solid foundation that a multilateral training approach develops will prepare the joints, muscles and connective tissues for demanding training. It’s at this stage that players who have followed a patient, long-term program will begin to reap tremendous rewards. Players who have been hot-housed into an intense, specialised program from an early age begin to lose interest or suffer frequent injuries. Here are the general guidelines for soccer conditioning in the 15-18 year old age group: • Introduce sport-specific conditioning such as repeated • • • • • • sprints, sharp twisting and turning and speed and agility drills. Speed and agility drills become more prevalent. Players are now capable of tolerating lactic acid accumulation so anaerobic training can be increased progressively. Continue to develop basic aerobic endurance capacity. Continue to develop and maintain flexibility. Strength training can become more intense with moderate to heavy loads employed gradually. Avoid maximal strength training (using loads where less than 4 repetitions can be lifted) until full maturity. Basic, low stress plyometrics can be added to the program increasing gradually to more intense depth jumps at full physical maturity. Multilateral training (i.e. non soccer-specific exercises) should still be encouraged, although they will make up a progressively smaller component of the overall program. Even elite, fully mature soccer players should reserve a phase of training for multilateral exercises - usually during the closed season. This helps to redress some of the imbalances that soccer invariably creates in the body. www.sport-fitness-advisor.com !13 Fit for Soccer - Junior Players Don’t Neglect Late Developers! In America, children born in December are less likely to succeed athletically compared to those born in January… and it has nothing to do with the alignment of the planets! Divisions are often determined by chronological age, grouping those born in the same calendar year. January babies have almost 12 months advantage over December babies – a big difference during childhood years. In the UK there is a similar phenomenon. British Premiership soccer players are more likely to be born between September and December. This puts them amongst the oldest in their school year competing against opponents who may be up to a year younger. All too often late developers are left to occupy the substitute benches while their bigger and stronger peers get most of the attention. Coaches opt for their strongest 11, often paying them more attention in training sessions. That’s unfortunate because it’s the late developers that often go on to play at a higher level enjoying longer careers. HOW TO PROGRESS A TRAINING PROGRAM Constant progression is key to any fitness plan at any age. Without it, players soon reach a plateau and improvement stops. When conditioning children, progression must be much more gradual and structured than it is in most soccer coaching programs. www.sport-fitness-advisor.com !14 Fit for Soccer - Junior Players A training program can progress in a number of ways – by increasing the duration of sessions, the frequency of sessions or increasing the intensity of each session. Only one of these should be chosen at a time and in children, it is best to increase the duration and frequency of sessions before the intensity. In the table above you can see that the program progresses every week. In sport, and particularly for younger athletes, a stair-step method of progression is more appropriate. Rather than increasing the intensity every week indefinitely, the program consists of a series of peaks and troughs: Week 3 Week 2 Week 1 Week 7 Week 4 Week 6 Week 8 Week 5 You can see in the diagram above that the program gradually increases to reach a peak in week 3. Week 4 sees a reduction in intensity before the cycle repeats itself. In practical terms, training sessions may appear like this: www.sport-fitness-advisor.com !15 Fit for Soccer - Junior Players HOW TO PREVENT OVERTRAINING Even the most careful and gradual progression cannot always prevent children doing too much, too soon. A sudden and marked drop in enthusiasm is one tell-tale sign, as are other subjective markers. However, mood changes can be difficult for even the most observant parent and coach to spot – especially when dealing with teenagers! One objective and useful measure is heart rate data. If you can get the player to take their heart rate each morning and plot it on a chart, it can provide an early indication of over-training or that the body is working a bit harder to fight off a cold or infection. Most children actually find it quite novel to do this and seeing their resting heart rate decrease over time with training can act as a great motivator. Here’s a sample chart of what the data might look like: www.sport-fitness-advisor.com !16 Fit for Soccer - Junior Players With these general principles in mind, let’s move onto the specific elements of fitness that are important in soccer starting with endurance. www.sport-fitness-advisor.com !17 Fit for Soccer - Junior Players SECTION 2 ENDURANCE TRAINING FOR JUNIOR PLAYERS ports fitness advisor www.sport-fitness-advisor.com !18 Fit for Soccer - Junior Players Endurance is the ability to sustain physical activity and withstand fatigue for prolonged periods. Not only is it important during a soccer match, a good endurance foundation is required to successfully complete technical and fitness-based training sessions. During a 90-minute adult soccer match, high-level players can cover as much as 8-miles (13km). A significant proportion of this will be in the form of sprints and strong runs repeated quickly with little time for recovery in between. While junior soccer matches are shorter in duration and of lower intensity, endurance still plays a key role. More mistakes are made during the latter stages of the game when fatigue begins to impair proper technique and concentration. ENDURANCE CAPACITY IN CHILDREN Endurance capacity improves naturally as a child matures. Compared to adolescents and adults, young children have a low cardiac output (the amount of blood pumped by the heart on one minute), an inferior blood oxygen carrying capacity, and poor tolerance to heat exhaustion. However, even in early childhood, athletic children outperform non-athletic children in endurance-based tests. Like in adult players, endurance is trainable in youngsters. Regardless of natural ability and genetic makeup, young children can increase their aerobic capacity by as much 10-20% per year, decreasing to 5-10% a year as they mature. www.sport-fitness-advisor.com !19 Fit for Soccer - Junior Players AEROBIC & ANAERBOIC ENDURANCE Broadly speaking there are two types of endurance – aerobic and anaerobic. Aerobic exercise takes place in the presence of oxygen. In other words, the activity is of low enough intensity that the heart can supply the working muscles with enough oxygen to meet their demands. Anaerobic exercise on the other hand, is fast, dynamic and intense enough that the heart is can’ keep up with the oxygen demands of the muscles. Activity is fuelled through other energy pathways that result in the accumulation of lactic acid, which quickly leads to fatigue. Unlike adults, pre-pubescent children have limited anaerobic capacity. They are unable to tolerate a build-up of lactic acid and must rely on aerobic metabolism during a soccer match and training session. Despite this, intense anaerobic training, even at an early age is likely to elicit greater results than lower intensity aerobic exercise. It is also more soccer specific. However, remember the multilateral approach to a child’s development. Any short-term rewards from intense anaerobic training are liable to result in longer-term problems and burn out. As a coach, you must resist the temptation to push young players with very demanding, consecutive drills that place a heavy burden on the anaerobic energy pathways. www.sport-fitness-advisor.com !20 Fit for Soccer - Junior Players ENDURANCE TRAINING PRE-PUBERTY (8-11 YEAR OLDS) The best athletes are those that are properly prepared, at each stage of their development, to cope with more demanding training later on. In this age group, endurance training should not be structured. For example, where older players may complete shuttle runs, or high intensity interval drills, children should be encouraged to improve their general fitness through games and play. Various modes of exercise should also be encouraged, such as swimming, as well as participation in other sports. This prevents the same muscles and the same joints being stressed in the same way over and over – a guaranteed way to induce burnout and injury. The first aim for coaches or parents working with this age group is to gradually increase the duration of exercise that children are able to cope with. ENDURANCE TRAINING GUIDELINES For children of this age, the term “training program” is a bit of a misnomer as it implies a structured and formal plan. This regimented approach should be avoided. Instead, exercises that develop endurance should be incorporated into fun activities that raise the heart rate and last longer than 20 minutes. www.sport-fitness-advisor.com !21 Fit for Soccer - Junior Players Group soccer coaching sessions are an ideal time to incorporate an element of endurance conditioning in 8 – 11 year olds (more details below). However, other activities can be completed outside of the group setting. This may include participation in various sports or modes of exercise such as swimming or cycling for example. Ideally, children should be physically active every day. To achieve an endurance training effect, strenuous exercise that raises the heart rate for a prolonged period should be completed 3 – 5 times per week. Mini circuits or obstacle courses similar to those described in the drills below (drill 3 and drill 4) are ideal and can be set up in the garden and completed with a parent. They are fun for children and convenient for parents. SAMPLE ENDURANCE TRAINING PLAN This example is by no means rigid and indeed a formal, structured program should be avoided. Other activities additional to these should not be discouraged but parents and coaches should keep a close eye on youngsters to ensure they are not feeling exhausted and burnt out. Remember that gradual progression is also important. This should start by increasing the duration of exercise sessions i.e. from 20 minutes up to 45 minutes per session over a number of weeks. When duration reaches a limit of around 60 minutes, the www.sport-fitness-advisor.com !22 Fit for Soccer - Junior Players number of sessions per week should be gradually increased (i.e. from 3 up to 4 and then 5). DAY Sample Endurance Training Plan Mon Tue Circuit or obstacle course in back yard Wed Group coaching session inc. endurance-based game(s) Thu Fri 20-60 minute swimming session Sat Sun Soccer game Obviously, children will take part in other physical activity during the week – physical education classes in school, participation in other sports and so on. These may or may not have a cardiovascular conditioning element to them. If they do, watch for signs of fatigue and over exertion. INCORPORATING ENDURANCE TRAINING INTO SOCCER COACHING SESSIONS www.sport-fitness-advisor.com !23 Fit for Soccer - Junior Players As a coach you may run one or two group sessions each week. While the session may predominately focus on basic skill development and ball control, games can be included that will have an endurance training effect. In a 60-minute session, you could start by keeping the total duration of these games to 10 - 15 minutes perhaps. This could be increased by 5 minutes each week until you reached the maximum amount of time you can dedicate to these types of games in your coaching session. Ideally, if you are able to, increase the overall session duration so that endurance-based games and play does not cut into your coaching time. Here is an example: Remember, that games do not necessarily have to incorporate a soccer ball. In fact, some games some weeks should not include a soccer ball at all. You may want to set up a throwing game or a simplified version of basketball or dodge ball (with light weight sponge balls of course!) for example. www.sport-fitness-advisor.com !24 Fit for Soccer - Junior Players Game 1 – Hit The Coach Equipment: 1 soccer ball per player • Each child is given a ball and stands in a line side-to-side. • The coach stands roughly 10 feet away from the players. • On the command, players must dribble and shoot at the coach • • while he / she runs slowly away. With large groups of players, recruit parents as ‘targets’ and split the group into a number of smaller games. Rest every 1 – 2 minutes and continue for up to 10 minutes. Game 2 – Tag Equipment: cones • An area approximately 20 meters/yards square should be • • • marked out. This may vary depending on the size of the group. The coach stands in the centre of the area while the players line up, side by side along one side. On the command, players must run to the other side while the coach tries to “tag” as many players as possible. Thos who are tagged before reaching the safety of the other side join the coach and try to tag the remaining players. Game 3 – Multi-Skill Circuit Equipment: Cones, soccer balls, stop watch, whistle, tennis ball, skipping rope • A number of activity stations are set up according to the size of • • • the group. Between 8 and 12 is ideal. Each station should focus on a different skill or activity. Not all stations need to be soccer-specific. The group is split into pairs and each pair assigned to a station. On the coach’s command, 1 player in the pair completes the station activity for 1 minute while the other rests. www.sport-fitness-advisor.com !25 Fit for Soccer - Junior Players • The coach signals the end of 1 minute and instructs the pairs • to swap over i.e. the resting player now completes the station activity. When both players have completed the station the entire group moves clockwise to the next station. This continues until each pair has completed all stations in the circuit. In effect players will have worked for 1 minute, rested for 1 minute and so on for a total of 20 minutes (assuming 10 stations). Station 7 Station 6 Station 8 Station 9 Multi-Skill Circuit Set-Up Station 5 Station 10 Station 1 Station 2 Station 4 Station 3 Note: It is a good idea to enrol the help of parents to explain the stations to each pair as they reach them. This saves going through instructions for the entire circuit at the beginning, which most under 10’s will only forget anyway! Children as young as 8 pick this up surprisingly easily and after completing the circuit once, they tend to remember it indefinitely. Here are some ideas for stations: www.sport-fitness-advisor.com !26 Fit for Soccer - Junior Players 1. Dribble ball in between a series of cones. 2. Side throws against wall i.e. in the style of rugby. Instruct players to alternate sides with each throw. If outdoors have the partner catch the ball and throw it back to the working player under arm. 3. Skipping with or without rope between two cones 10 meters/ yards apart or on the spot. 4. Target practice: Place two cones 1-2 meters apart to create a mini goal. Player starts 3-5 meters away with a ball and aims to pass into the goal. The player must run and retrieve the ball and take aim again from the same starting position. The resting partner can keep score. 5. Strength exercise (see section 2 for suitable examples for 8-11 year olds). 6. Side stepping or shuffling between cones 10 meters / yards apart. 7. High throws. Using a soccer ball the player squats down and tries to throw the ball directly up as high as possible. Older players can be instructed to catch it. Younger players are better suited to a sponge ball for this exercise. www.sport-fitness-advisor.com !27 Fit for Soccer - Junior Players 8. Hopscotch or running slalom around cones. 9. Target practice: Players must throw a tennis ball or beanbag at a target. They run to retrieve the ball and return to the start before having another attempt. Resting player can keep score. 10.Dribble ball in between a different series of cones. Game 4 – Obstacle Course Equipment: Soccer balls, cones, benches, beanbags, hoops, mats, hurdles As obstacle course is a great way to develop multilateral fitness. Designed properly they can help to improve balance, coordination and motor skills as well as general endurance. Not all sections of the course need to be soccer specific and adding a variety of skills will increase the fun! You can set an obstacle course up in a gym, sports hall or on a playing field. Here are some ideas that you can combine into your own course: 1. 2. 3. 4. 5. 6. Walking along low, narrow benches (improves balance). Tumbles and forward rolls on a mat. Hopscotch. Crawling under hurdles. Jumping over low hurdles. Jumping over low hurdles followed by a forward roll, followed by a jump and twist in the air. 7. Target throw – have a pile of beans bags to the side, enough for each player. The player picks up the bean bag and throws it at a target or bucket then continues on the course. www.sport-fitness-advisor.com !28 Fit for Soccer - Junior Players 8. Zigzags or slaloms between cones or high poles. 9. Bounding over cones or into rings The coach / or parents can be stationed at various points in the course to feed a ball for a pass back or header back. You can even finish the course with a shot at goal. Game 5 – Controlled Soccer Games By simplifying the rules, mini soccer games can increase participation. Small-sided games (as little as three per side) are preferably to larger games, as each child will be motivated by the fact they are likely to see lots of the ball. Here are some examples: 2 v2 With Centre goal Mark out a grid of approximately 15 x 20 yards/meters. A goal 5 yards/meters wide is set up with 2 cones in the centre of the grid. A goal is scored when the ball is dribbled or passed through the goal. Possession changes after every goal or if the ball is knocked out of the grid. 3v3 Goal Zones Mark out a grid of approximately 20 x 40 yards/meters. At either end mark an area about 5 yards/meters deep. This is the goal zone. Both teams start in their own goal zone. The teams of three must try to pass the ball from their own zone into the opposition’s zone. A goal is scored when a pass is successfully completed from outside the goal zone into the goal zone. www.sport-fitness-advisor.com !29 Fit for Soccer - Junior Players 5 yds/m 30 yds/m 20 yds/m The Blob All the players are inside a large grid. All but three have a soccer ball at their feet. The three without a ball form a 'blob' by holding hands. The blob moves freely in the grid and tries to kick any players’ ball out of the grid. If a player’s ball leaves the grid he/she joins the blob. Once a chain has six or more players, have it break apart into two smaller chains (of three people each). The last player dribbling is the winner. Coaching Points: • Stay away from the blob. • Don’t get trapped - move into space away from the blob. • Keep control of the ball - don’t kick it too far away. • Work together - the blob must work as a team. This is obviously a small sampling of possible games. The variations are endless but you bear the following two points in mind when designing your own games: www.sport-fitness-advisor.com !30 Fit for Soccer - Junior Players Avoid games that keep most of the children standing around for long periods. This includes relays and any activity that creates lines. Reward participation rather than winning. Games that create a winner or loser should be avoided. However, two teams pitted against each other is suitable, especially if teams are changed each session. ENDURANCE TRAINING PUBERTY (11-15 YEAR OLDS) As children reach puberty, their endurance capacity (VO2max) increases naturally. Boys begin to outperform girls in both strength and endurance events. Anaerobic capacity also increases markedly, as does a tolerance of lactic acid accumulation. However, the anaerobic system is not fully developed until after puberty so the introduction of intense interval training should be slow and progressive. Rapid growth spurts can leave adolescents susceptible to overuse injuries such as Osgood-Schlatter disease. These can be exasperated by continuous-type endurance activity, particularly on hard surfaces. The onset of puberty also increases sweating. Regular water breaks should be scheduled throughout training sessions to ensure adequate fluids can be taken on board, especially in warm conditions. www.sport-fitness-advisor.com !31 Fit for Soccer - Junior Players ENDURANCE TRAINING GUIDELINES Endurance activities should be predominantly non-specific and aerobic in nature in this age group. For coaches and parents, this means resisting the temptation to prescribe intense interval drills that will improve a player’s fitness more dramatically, but will also lead to fatigue and burn out. In the younger 8 – 11 age we saw that training sessions and drills designed specifically to improve endurance are not recommended. Instead, games and activities that are fun and happen to build endurance as a side effect are the better choice. As players move into this age group, these games can be replaced with activities that more closely resemble conditioning exercises. However, monotonous running drills with or without a ball should be avoided. Some training sessions away from group or team training can also be gradually included into the program. You’ll see some sample endurance drills below. These are categorised as either aerobic or anaerobic. For younger players (11 – 13) chose only aerobic activities. These will help improve the pumping power of the heart, increase stroke volume (the amount of blood pumped per beat), enhance oxygen delivery through an increase in capillaries (tiny blood vessels) and lower the rest heart rate. All of these adaptations are important foundations for more intense training later on. Towards the later stages of this age group (14 – 15), anaerobic drills, also called interval training, can be added to the program. It’s only at this stage, with a solid foundation in place, that training begins to become soccer-specific. www.sport-fitness-advisor.com !32 Fit for Soccer - Junior Players Continue to encourage other modes of exercise and sports participation however. While soccer-specific endurance exercises can be included in the program, they should not necessarily dominate it. Even older players in this group (14 – 15) should focus mostly on aerobic endurance activities. *Remember these are approximate guidelines for this age group. Individuals of the same age vary greatly in their development. Exercise should be prescribed based on biological rather than chronological age. Progression, as with the 8 – 11 year old age group should come first from an increase in exercise duration rather than intensity. You will see in the sample training plans below that after the duration has reached around 60 minutes an extra session is added. www.sport-fitness-advisor.com !33 Fit for Soccer - Junior Players SAMPLE ENDURANCE TRAINING PLANS Below are some examples for incorporating endurance training into a week-by-week plan. Training can become more structured as players mature but it is still important to emphasise fun and variety, especially in younger players. In this sample program, one endurance training session compliments a team training session, participation in another sport and a soccer match to make up four total sessions for the week. www.sport-fitness-advisor.com !34 Fit for Soccer - Junior Players The program progresses by increasing the duration of the endurance session and then by adding an additional session in week 6. The coloured blocks represent the overall intensity of the week. Rather than increasing every week, they follow a fourweek cycle of progression. When the maximum duration per session (approximately 60 minutes) and maximum number of sessions per week (4 – 5) has been reached, intensity can be gradually increased. This might involve completing exercises more quickly, allowing additional repetitions to be completed in the same time. Once the maximum duration, number of sessions and intensity has been reached, the program should be maintained. However, it should follow a series of peaks and troughs with difficult weeks followed by easier weeks. Pay close attention for signs of fatigue and over-training and significantly reduce the duration and number of sessions until enthusiasm returns. www.sport-fitness-advisor.com !35 Fit for Soccer - Junior Players This program is similar to the example above only it has been adapted for older players in this age category. Endurance training should further develop the gains made in aerobic power with the gradual introduction of some anaerobic work. Even in the mid teens, youth players should not be discouraged from avoiding other sporting activities, even if they plan to specialise in soccer. These other sporting interests are useful during the closed or off-season and can provide a form of conditioning whilst offering respite from soccer. www.sport-fitness-advisor.com !36 Fit for Soccer - Junior Players By the age of 15 or 16, a player who has followed a progressive program of multilateral training will have a superb athletic base on which to build soccer-specific fitness. Not only will they be fully prepared to cope with the demands of intense training, they are likely to have a long and successful career in the game. SAMPLE ENDURANCE TRAINING DRILLS The following drills have been split into two categories aerobic and anaerobic. Both have their advantages and even at an elite adult level a combination of drills will be used in a soccer conditioning program. During puberty aerobic drills should predominate. This is especially true in younger players (11–13) who don’t posses sufficiently developed anaerobic energy systems to cope with the by-products of very intense training. In younger players, keep to aerobic endurance drills and activities exclusively. In older players that fall into this group, gradually introduce some of the anaerobic drills below. Keep closely to the suggested rest intervals. These are longer than they would be for adult players and allows the players to recover sufficiently between repetitions. www.sport-fitness-advisor.com !37 Fit for Soccer - Junior Players AEROBIC ENDURANCE TRAINING DRILLS (CONTINUOUS TRAINING) Drill 1 – Technical Running Soccer players spend a lot of time running in a game, much of it in a semi-fatigued state. With this fatigue it is very easy for running form and movement economy to diminish and this leads to further fatigue and reduced performance. By teaching players correct running technique from an early age, it will be ingrained within in by the time they are old enough to complete more intense training. It’s much more difficult to teach older players how to unlearn such a common movement for them and then re-learn it correctly. The table below covers the important technical points. These can be practiced during warm ups and cool downs to help ingrain correct mechanics. While this drill won’t improve endurance directly, over time it will help to improve running economy, which is a very important factor in endurance performance. www.sport-fitness-advisor.com !38 Fit for Soccer - Junior Players Head Head should be erect, with eyes focused forward to a point on the ground about 20 to 30 metres/yards away. Shoulders Shoulders should be square and level. Do not round your shoulders or swing them forwards or backwards. Arms Arms should swing freely in a general forwards/backwards motion. Elbows should be bent approx. 90 degrees with forearms roughly parallel to ground. Hands Hands are held in a relaxed fist with the thumb resting on the forefinger. Torso Torso should be erect, with chest up. Do not lean forwards, backwards or slouch, as all of these posture deviations can place of stress on lower back. Legs The leg action should be relaxed. Knee lift should not be too high as in sprinting. Feet Foot strike (landing) should be with the heel and rolling onto the ball of the foot before leaving the ground again. Drill 2 – Fartlek Training Fartlek training is less monotonous than continuous running and more specific to soccer. It involves running for 20-30 minutes or so at varying paces and intensities. Here are two sample sessions suitable for soccer: Easy Farltek Session (ages 11–15) • Warm up with a steady jog for 10 minutes. • Run hard for 3 minutes, jog slowly for 1 minute. • Repeat 6-8 times. • Cool down at a steady pace for 10 minutes. www.sport-fitness-advisor.com !39 Fit for Soccer - Junior Players Hard Fartlek Session (ages 13–15) • Warm up with a steady jog for 10 minutes. • Run hard, for 75 seconds. • Jog for 150 seconds. • Run hard for 60 seconds. • Jog for 120 seconds. • Repeat 3-4 times. • Cool down at a steady pace for 10 minutes. Drill 3 – Keep Possession 3v3 Equipment: cones, soccer balls • Mark out an area roughly 20 x 25 yards/meters. • Form two teams of three players. One team starts in possession of the ball and must keep it for as long as possible. • Possession changes if the ball is intercepted or leaves the marked area. • A goal is awarded for every 6 consecutive passes. Play continuously for 15-20 minutes. Drill 4 – Modified Hoff Circuit Equipment: cones, low hurdles, soccer balls • Mark out a course according to the diagram below. • From the start, dribble around the cones. • Dribble up to hurdles passing the ball underneath and jumping • • • • over the top. Dribble around the next set of diagonal cones with fewer touches to increase speed. Dribble backwards for 10 yards/meters to the gate, turn and dribble forwards back to start. Each player completes the circuit as quickly as possible keeping close possession of the ball. With a group of players stagger the start keeping at least 3 to 5 yards/meters between each player. www.sport-fitness-advisor.com !40 Fit for Soccer - Junior Players • Complete 3-5 circuits back to back. Rest for 2 minutes and repeat for 2-3 sets. www.sport-fitness-advisor.com !41 Fit for Soccer - Junior Players Drill 5 – Figure Running Equipment: cones, soccer balls • Mark out a course similar to the diagram below. • The team is split into four equal groups, with one group per • • • • • station. On the coach’s command players must dribble a ball around the designated figure continuously for 5 minutes. Players within each group should stagger their starts to allow a few yards room between each other. It is not a race and players should avoid overtaking. After 5 minutes each group immediately moves to the next station. Repeat until all four stations have been completed. www.sport-fitness-advisor.com !42 Fit for Soccer - Junior Players Drill 3 – Progressive Shuttles Runs Equipment: cones • Set out 5 cones 10 yards/meters apart. • Starting on cone 1, jog to cone 4 then immediately sprint to • • • • • cone 5. Turn and jog to cone 3 and then sprint to cone 1. Turn and jog to cone 2 and sprint to cone 5. Finally, turn immediately and sprint to cone 1. Rest for 60 seconds and repeat 3 times. This is one set. Complete 2-3 sets. www.sport-fitness-advisor.com !43 Fit for Soccer - Junior Players ENDURANCE TRAINING POST-PUBERTY (15-18 YEAR OLDS) Until this point endurance training has been predominantly general and aerobic in nature. This patient, long-term approach leads to better, more wellrounded soccer players when they hit maturity. Not only will they be less susceptible to injury, they will also have a solid foundation giving them the best chances of reaching their full potential. However, to excel in soccer (or any sport), training should mirror the demands and movement patterns of the game. Post puberty there is a shift away from general endurance training to soccerspecific conditioning. A training plan takes on far more structure and very often conditioning sessions are completed separately from tactical and coaching sessions. It’s important to remember that just because a player turns 15 or 16 or even 18 does not mean they are able to cope with all forms of training. Physical and psychological development varies greatly so this is not the final phase of development. The training principles for players 18+ are different again and mirror those used by the world’s top players. You can find more details in the senior version of Fit For Soccer. www.sport-fitness-advisor.com !44 Fit for Soccer - Junior Players ENDURANCE TRAINING GUIDELINES Although endurance sessions should become soccer-specific at this age, they should do so progressively. Even elite adult players, start their pre-season with general aerobic endurance training for several weeks. This prepares them for more demanding interval training and anaerobic work. Soccer-specific conditioning can be intense. As players become fitter, it requires more time and more effort to further improve each element of fitness (speed, endurance, strength etc.). Without a proper plan in place, one or more important fitness components suffer or players quickly become burnt out from doing too much. The way that professional and college level teams deal with this challenge is to use a concept called periodisation. This simply means breaking the overall program (usually 12 months long) into several distinct periods or phases. From a conditioning perspective, endurance training changes over these phases. Here are the four most relevant phases to soccer that you are probably already familiar with: Early Pre-Season: aerobic endurance predominates. Late Pre-Season: anaerobic endurance predominates. In-Season: maintain aerobic and anaerobic endurance. Closed Season: aerobic endurance with cross training. www.sport-fitness-advisor.com !45 Fit for Soccer - Junior Players You may use different terms such “off season” instead of preseason or “competition season” instead of in-season, but the principle remains the same. The parameters for endurance training in this age group differ from younger age groups. Intensity can be increased as can volume while rest intervals decrease. Depending on time available 2 – 4 endurance sessions per week is usually required. However, as you will see in the final chapter, these can be combined with other forms of training (such as speed drills) into one session. * Remember these are approximate guidelines for this age group. Individuals of the same age vary greatly in their development. Exercise should be prescribed based on biological rather than chronological age. Aerobic training can be completed either continuously at a steady pace, or in intervals. Interval training consists of breaking up the total distance into smaller distances or intervals and then completing each at a higher intensity. A short break between www.sport-fitness-advisor.com !46 Fit for Soccer - Junior Players each interval allows the overall intensity to be much higher than simply running the full distance non-stop. A training plan for 16–18 year olds comprises of more interval training than continuous training. In fact continuous training is only used during the closed season and when players return back to training. Progression must be gradual and allow players to adapt to each new increase in training load. Endurance sessions can be progressed either through an increase in duration (by increasing the number of sets and repetitions) or intensity (by decreasing the rest interval time). SAMPLE ENDURANCE TRAINING PLANS Below are some examples for incorporating endurance training into a week-by-week plan. Each example covers a specific phase of the soccer season. You will also find descriptions of the drills listed in these charts. www.sport-fitness-advisor.com !47 Fit for Soccer - Junior Players This pre-season program above would start about 12 weeks before the beginning of the competitive season. Teams usually have practices matches towards the start of the season, which need to be factored into the plan. The program progresses gradually from steady, continuous training, to more intense interval training and finally to anaerobic training. While three sessions might not seem like much, www.sport-fitness-advisor.com !48 Fit for Soccer - Junior Players remember that other forms of training as well as skill and tactical sessions must also be considered. For 16 year olds or later developers, the program may need to progress more slowly than this. The pre-season should be used to build a solid aerobic base with continuous training followed by interval training. Older players who have fully matured may be able to cope with slightly quicker progression, but a peak won’t be reached until the competitive season has begun. A Note About Practice Matches Practice games or “friendlies” are as much about conditioning as they are about tactical preparation. The priority for team selection should be to give the as much of the squad as possible an opportunity to improve their match fitness. Players that miss a practice game or play less than 20 minutes, can complete a short conditioning session the following day, or even following the game where time allows. Intense training should be avoided the day before a competitive game. While this is not as important before a practice match, players are often keen to impress the coach and can only do so when they are reasonably fresh. The following program is an example of how endurance training continues into the in-season. Crucially, there is now a game (or two) each week to consider. Completely negate endurance training and you rapidly lose the gains made in pre-season. Too much, and players are left fatigued and unable to perform at their best. www.sport-fitness-advisor.com !49 Fit for Soccer - Junior Players This program aims to maintain the gains made in pre-season. Usually however, players will continue to improve over the course of the season as they gain more and more match fitness from playing competitive games. A match can be counted as an endurance session so players who do not play a game (or play less than 20 - 30 minutes) can be encouraged to complete some endurance training afterwards or on the following day. This 4-week cycle could be continued indefinitely throughout the course of the competitive season. Obviously there will be times when it is impossible to follow this sequence of increasing and decreasing intensity. It’s the general concept of scheduling some www.sport-fitness-advisor.com !50 Fit for Soccer - Junior Players rest weeks that is important, rather than just pushing players to their maximum week in week out. The plan below is also for the in-season but assumes there are two games per week. Two matches per week leaves little time for endurance training. Recovery is the most important factor and players should avoid heavy training the day before and the day after a game. www.sport-fitness-advisor.com !51 Fit for Soccer - Junior Players Cross Training for the Closed Season During the closed or off-season players should take a break from soccer. This allows both physical and psychological respite and is crucial if they are to start each season with energy and enthusiasm. However, taking a break from soccer should not mean taking a break from all physical activity and exercise. The majority of gains made from training are soon lost (in as little as 4 weeks) so it’s important for players to keep themselves ticking over and at the same time allow their bodies to recuperate. The best way to do this is through CROSS TRAINING. Players choose another sport or activity they wouldn’t normally take part in. This might be another sport such as tennis or basketball or an activity like swimming (avoid too much running). Joints and muscles are given a rest from the stresses of soccer but the cardiovascular system is still taxed enough to maintain fitness. As a general rule, players should aim for 3 – 5 cardiovascular sessions per week lasting 30 – 60 minutes. www.sport-fitness-advisor.com !52 Fit for Soccer - Junior Players SAMPLE ENDURANCE TRAINING DRILLS The endurance drills in the 12–15 age category are all suitable for this age group. The intensity can be adjusted by reducing rest intervals, increasing distances or increasing the number of sets and repetitions. Below are some additional drills that are more advanced and suitable for players who are post puberty. CONTINUOUS AEROBIC ENDURANCE DRILLS See drills in the 11–15 age category. INTERVAL AEROBIC ENDURANCE DRILLS Drill 1 – Diagonal Pitch Run • Using the markings of a soccer pitch, start on the touchline at the halfway point and with the ball run ¾ pace to the corner flag. • Run ¾ pace diagonally to the opposite side of the pitch at the halfway point. • Jog along the half way line for recovery back to the start. • Continue by using the other half of the pitch without the ball (leave at start position). www.sport-fitness-advisor.com !53 Fit for Soccer - Junior Players • Repeat 3-5 times and rest for 2 minutes. This is 1 set. Complete 2-3 sets. For large groups of players send half the group off towards one corner flag and half to the opposite corner flag. Make sure players keep as tight together as possible. This drill can also be completed without a ball. www.sport-fitness-advisor.com !54 Fit for Soccer - Junior Players Drill 2 – Penalty Area Run • Using the penalty area markings start on one corner facing down the goal line. • Run along the goal line to the corner of the penalty area. • The coach or partner throws the ball to head or volley back (individuals can perform a mock header). • Side-step leading with the left leg to the next corner. • Run backwards to the next corner. • Side-step back to the start and repeat for 1 minute. • Rest for 60 seconds and repeat 3-5 times. This is one set. • Rest for 2 minutes between sets and complete 2-3 sets in total. www.sport-fitness-advisor.com !55 Fit for Soccer - Junior Players ANAEROBIC ENDURANCE DRILLS Drill 1 – Penalty Spot Runs • Using the dimensions of the penalty area • (or similar set up with cones) take a starting • position on the penalty spot. • Sprint to one corner of the box and back, then to the next corner and back and so on for all four corners. • Rest for 60 seconds and repeat for a total of 3-5 times. This is one set. • Rest for 2 minutes with active recovery (such as ball jugging or walking) and complete a total of 2-3 sets. www.sport-fitness-advisor.com !56 Fit for Soccer - Junior Players Drill 2 – Shuttle Runs A classic but still outstanding drill for developing anaerobic endurance. Despite the simplicity of this exercise it can still be very demanding. Start with the minimum number of sets and repetitions building up gradually. • Place 5 cones out 10 yards/meters apart. • Starting on cone 1, run to cone 2 and back, then cone 3 and • • • • back, 4 and back, then 5 and back. The sprint should be flat out and with emphasis on sharp turns. Rest for 30-45 seconds and repeat. Rest another 30-45 seconds and repeat for a third time. This is one set. Rest for 2 minutes with active recovery such as walking. Complete a total of 3-5 sets. If you work with older players (16+) you may want to take a look at the senior version of Fit For Soccer. This contains many more drills for aerobic and anaerobic training as well as complete periodized plans for ambitious adult players. www.sport-fitness-advisor.com !57 Fit for Soccer - Junior Players SECTION 3 STRENGTH TRAINING FOR JUNIOR PLAYERS ports fitness advisor www.sport-fitness-advisor.com !58 Fit for Soccer - Junior Players For many years coaches and athletes believed that strength training was detrimental to sports performance. The misconception was that lifting heavy weights would lead to excessive muscle bulk, hampering the ability to perform fine, intricate motor skills. Today that attitude has changed completely and coaches from virtually every sport, including soccer, acknowledge the enormous benefits that a well-planned strength training program can bring. Resistance training for children however, is still largely misunderstood and controversial topic. Children are often discouraged from all forms of strength training for fear it will lead to injury and damage to growing bones. Ironically, contact sports such as soccer, are more likely to cause injury and a properly designed strength plan can be one of the most effective methods of injury prevention. This section covers resistance training guidelines for soccer players aged 8 to 18. The sample program and sessions are designed to develop injury-free players whilst improving performance. As with all other types of conditioning, the key is to take a patient, long-term approach. A general base of core strength as well as ingraining correct technique is the main aim for young players. Only then, and when players are physically mature, can soccer-specific strength and power be built on top. STRENGTH TRAINING BENEFITS Strength training for juniors bears no resemblance to competitive weightlifting or power lifting where heavy loads are lifted to www.sport-fitness-advisor.com !59 Fit for Soccer - Junior Players exhaustion. Even players who may appear physically mature (16 to 18) are usually not ready for maximal strength training. However, this doesn’t prevent many of the advantages of resistance training from being received. With the correct exercises, amount of resistance and a suitable number of sets and repetitions, children and youths can enjoy the following benefits: • Increases mineral content in bones helping to prevent • • • • • • osteoporosis in later life. Raises resting metabolic rate helping to offset fat gain and combat obesity. Can help to prevent injuries common in soccer by strengthening ligaments and tendons. Can help to prevent or reduce the severity of injuries associated with rapid growth spurts during adolescence. Improves kicking power and passing range. Improves speed, agility and jumping power. Enhances self-discipline, confidence and self-esteem. To achieve all of these benefits safely, young players must follow a long-term. Progressive program. The goal is to build a solid, general foundation over a prolonged period so that later (after puberty), it can be converted into soccer-specific strength and power. CAN STRENGTH TRAINING STUNT GROWTH Bones reach their full length when the growth plates at either end ossify (meaning the cartilage turns into bone). This www.sport-fitness-advisor.com !60 Fit for Soccer - Junior Players ossification process is not fully complete until after puberty and in some individuals it may not occur until age 18 or older. It’s the potential damage to these growth plates that has been one of the biggest causes of concern amongst coaches of young athletes and perhaps the main reason why children are told not to lift weights. Growth plate injuries along with compression injuries in the shafts of the bone can be serious and in some cases can lead to stunted growth and impaired development. In young children, ligaments are stronger than bone so a sudden force that would cause a ligament to tear in an adult may actually cause a growth plate fracture in a child. Similar to this, explosive movements that lead to a muscle tear in adults, can cause the tendon to separate from the bone in children. These injuries can occur during contact sports and also with very intense weight lifting. For these reasons, lifting very heavy weights (i.e. greater than 70 – 80% one repetition maximum) must be avoided in children prior to and during puberty. It is also not recommended for anyone under the age of 18 even if they appear to be physically mature. On the other hand, lifting lighter weights with proper technique can actually protect players from these types of serious injuries. According to Strength & Conditioning expert Tudor Bompa, athletes who do no weight training are three times more likely to suffer injuries than those who do. www.sport-fitness-advisor.com !61 Fit for Soccer - Junior Players STRENGTH TRAINING SAFETY More than anything else, strength training for prepubescent children should emphasise proper technique and form over the lifting of heavy weights. Trying to do too much, too soon is the main cause of injury. Even during and shortly after puberty, maximal strength training (i.e. lifting loads that allow only 1 - 5 repetitions) should be avoided. Here are some other guidelines that compliment those outlined under each age category in the sections that follow: • Children must be supervised at all times. Exercises should • • • • • • be spotted by a competent coach who understands correct form and spotting techniques. Unlike the bodybuilding mentality, training should not cause discomfort. Children should avoid lifting to failure (i.e. completing a set of repetitions to exhaustion) and techniques such as supersets and drop sets. There must be an adequate phase of learning with little or no weight so that proper technique can be taught. Check all equipment before use. Make sure collars and bars are secure if free weights are used. Children (and adults) should not drop weights. Aside from obvious safety issues when others are around, a muscle under high tension that relaxes sharply (when dropping the weight instead of carefully lowering it) is prone to tearing. Strength training should be preceded by an adequate warm up and followed by a suitable cool down. A warm up can consist of 10 minutes of light aerobic exercise followed by some dynamic stretching. Progression should be very gradual – more so than in adults. Do not aim to increase the resistance or volume every session. www.sport-fitness-advisor.com !62 Fit for Soccer - Junior Players • Training plans should focus on core muscles rather than limbs and general strength rather than power or strength endurance. The chart below gives a broad outline of how strength training differs and progresses as athletes grow and mature: You will find guidelines for sets, repetitions and loads and sample exercises in the following sections. www.sport-fitness-advisor.com !63 Fit for Soccer - Junior Players STRENGTH TRAINING PRE-PUBERTY (8-11 YEAR OLDS) According to the American College of Sports Medicine, boys and girls as young as 7 and 8 years old have benefited from strength training. The ACSM goes on to state that there is no reason why children younger than this can’t participate in strength-related activities such as push-ups and sit-ups if they are able to follow instructions. Their rule of thumb is “…if children are ready for participation in organised sports or activities – then they are ready for some type of strength training” To re-emphasise however, children in this age group should never lift heavy weights. They should not attempt to find out how much they can lift for a one repetition maximum or complete sets of exercises to failure or exhaustion. This is when strength training can become more harmful than helpful and cause potentially long term damage to growing bones. STRENGTH TRAINING GUIDELINES Remember that during this age, multilateral development is the main objective – helping children to develop all-round basic athletic skills that are not specific to any particular sport. From a strength training point of view, the aim is to build a solid foundation that develops all the tendons, ligaments and muscles, in proportion, and without a highly regimented routine. www.sport-fitness-advisor.com !64 Fit for Soccer - Junior Players One of the best ways to achieve this is through circuit training. Circuit training avoids the intensity and stress of back-to-back sets of the same exercise, working the same muscle groups. It also allows greater recovery between exercises and set up correctly, can help to minimise fatigue in young players. Just as importantly, the variety of a circuit training session helps to keep children motivated and interested. Here are the parameters for a circuit training session: * Remember these are approximate guidelines for this age group. Individuals of the same age vary greatly in their development. Exercise should be prescribed based on biological rather than chronological age. The resistance of all exercises must be light. Children should be able to perform at least 12 – 15 repetitions comfortably and without straining. If an exercise cannot be completed for at least www.sport-fitness-advisor.com !65 Fit for Soccer - Junior Players this number of repetitions, it is too difficult and the resistance should be lowered or the exercise replaced for another. Children must be allowed to perform the exercises at their own speed and not as fast as possible. They should never be pushed to discomfort as is common in adult weight training. Reward should be for self-improvement (especially with regard to technique) rather than for standing out in a group. EXERCISE SELECTION Exercise selection is important in any resistance training routine and perhaps more so when dealing with young athletes. Various types of equipment can be used such as resistance bands (lowest resistance, typically yellow in colour), light medicine balls (2kg / 5lbs), light dumbbells or simply bodyweight. Resistance machines should be used with caution or avoided, as they are not designed for the length of children’s limbs. When selecting exercises there is no reason why various types of equipment cannot be interchanged. The key is to emphasise the core muscle groups, rather than the limbs, with a varied selection of exercises. When designing a circuit training session, it’s a good idea to alternate muscle groups and body parts to help prevent local muscle fatigue. There is no set way to alternate muscle groups but one popular method is: Lower body / Upper body / Core www.sport-fitness-advisor.com !66 Fit for Soccer - Junior Players In this example a lower body exercise (such as step ups) is followed by an upper body exercise (such as a medicine ball throw) followed by a core exercise (such as crunches). This sequence is continued for a total of 6 – 9 stations. SAMPLE STRENGTH TRAINING SESSIONS Below are three sample circuit training sessions. They consist of several exercise stations that you may not class as traditional resistance exercises. This is to help keep the routine fun, less structured and to keep the overall intensity to a minimum. You can see the exercises for these routines below. www.sport-fitness-advisor.com !67 Fit for Soccer - Junior Players www.sport-fitness-advisor.com !68 Fit for Soccer - Junior Players Progression should be very gradual in this age group and only one parameter (such as the number of exercises, number of circuits and session per week) should be altered at a time. Here’s how the program might progress: 1 session per week, 6 exercises and 1 circuit per session. 1 session per week, 9 exercises and 1 circuit per session. 1 session per week, 6 exercises and 2 circuits per session. 1 session per week, 9 exercises and 2 circuits per session. 2 sessions per week, 6 exercises and 1 circuit per session. 2 sessions per week, 9 exercises and 1 circuit per session. 2 sessions per week, 6 exercises and 2 circuits per session. 2 sessions per week, 9 exercises and 2 circuits per session. Fun and variety are key components of a strength training program in this age group. As such, you may want to alternate exercises and routines regularly to maintain interest and prevent certain muscles groups from being over or under used. www.sport-fitness-advisor.com !69 Fit for Soccer - Junior Players SAMPLE STRENGTH TRAINING EXERCISES Here are the resistance exercises for the sample circuit routines above: LOWER BODY EXERCISES Box Step Ups 1) Use a box approximately 30cm (12in) high. 2) Step up with the right foot and follow with the left foot so that both feet are on the box. 3) Step down with right foot first and then the left foot. 4) Repeat this sequence (leading with the right foot) for 15 seconds and then switch to lead with the left foot for the remaining 15 seconds. Bodyweight Squats 1) Start by placing feet shoulder width apart and holding your arms out in front of you. 2) Proceed to squat down like you are going to sit in a chair. Your upper body will lean forward slightly and your hips will shift backwards while going down. 3) Remember to keep your knees from going out in front of your toes while squatting. 4) Repeat according to your required repetitions. If you want to make the exercise more challenging hold your arms at your sides or behind your head. www.sport-fitness-advisor.com !70 Fit for Soccer - Junior Players Stationary Bodyweight Lunges 1) Stand with feet hip width apart. Take left leg and step back approximately 2 feet standing on the ball of the foot. 2) Start position: Feet should be positioned at a staggered stance with head and back erect and straight in a neutral position. Place hands on hips. 3) Lower body by bending at right hip and knee until thigh is parallel to floor. Body should follow a straight line down towards the floor. 4) Return to start position. Alternate or switch to other leg after prescribed reps. 5) Remember to keep head back, and hips squared and in a neutral position throughout movement. Skipping (Alternate Feet) 1) Start with the jump rope in each hand. 2) Jump off the ground and start swinging the jump rope under your feet. 3) Continue jumping up and down alternating your feet touching the ground as you bring the rope under your feet. 4) Continue for the recommended number of jumps or time.

An intense soccer-specific strength program at this stage can lead to injury and potential long-term problems. Even towards the end of puberty the ossification process (cartilage turning into bone) is not complete so heavy weight lifting must be avoided. Bones grow more rapidly than muscles develop during this stage, which can lead to many common overuse injuries. A combination of strength and flexibility (see section 5) exercises can help to reduce the severity and occurrence of such injuries. STRENGTH TRAINING GUIDELINES It’s important that strength training during puberty develops a balanced musculature (unlike sport-specific training). A wide variety of non-specific exercises should be selected so that no muscle groups are neglected. A circuit training format is still the best option for this age group. Avoid bodybuilding-type routines that cal for multiple sets of one exercise performed consecutively. This is too exhausting and intense on developing bodies. The resistance of all exercises must be low enough to allow at least 12–15 repetitions to be performed. If fewer repetitions can www.sport-fitness-advisor.com !77 Fit for Soccer - Junior Players be completed the resistance should be lowered or the exercise replaced for another. Although the final few repetitions of an exercises maybe taxing, players should avoid pushing themselves to failure on each exercise completed. Here are the parameters for a circuit training session: * Remember these are approximate guidelines for this age group. Individuals of the same age vary greatly in their development. Exercise should be prescribed based on biological rather than chronological age. Allow athletes to perform the exercises at their own speed and discourage fast and explosive actions in favour of controlled movements. Continue to reward self-improvement rather than for standing out in a group. www.sport-fitness-advisor.com !78 Fit for Soccer - Junior Players If a circuit is performed as part of a longer group coaching session, it should be completed after technical and speed /agility work towards the end of the session. EXERCISE SELETION As with younger age groups, continue to emphasise exercises using bodyweight, medicine balls, light resistance bands and light dumbbells. The weight of the medicine balls can be increased from 2kg (5lbs) to 4kg (9lbs). Dumbbells should be light enough to allow at least 10 – 12 repetitions. Light and empty barbells can be introduced at this age in order to teach correct technique for exercise such as half squats and bench presses. Start with a light broomstick until technique is perfected, gradually progressing to an empty barbell. A small amount of weight can be added as the player progresses. Machines may still be unsuitable for the majority of players that fall into this group. However, older players in the group who are early developer and so taller than average, may be able to use some machines safely and correctly. Core muscle groups should be emphasised helping to further build a solid, athletic base. You may also want to alternate exercises in the circuit in the following way: Lower body / Upper body / Core www.sport-fitness-advisor.com !79 Fit for Soccer - Junior Players SAMPLE STRENGTH TRAINING SESSIONS Below are three sample circuit training sessions. Each one is slightly more demanding than the one before. You can see the exercises for these routines below. www.sport-fitness-advisor.com !80 Fit for Soccer - Junior Players www.sport-fitness-advisor.com !81 Fit for Soccer - Junior Players Progression must be gradual and, as with younger age groups, only one parameter (such as the number of exercises, number of circuits and session per week) should be altered at a time.

Catch ball on the bounce from your partner and repeat according to prescribed repetitions www.sport-fitness-advisor.com !92 Fit for Soccer - Junior Players STRENGTH TRAINING POST-PUBERTY (15-18 YEAR OLDS Until this stage in a young athlete’s development, strength training has been used to develop an all-round, solid foundation of general strength. This can now be progressively converted into soccer-specific strength and power. Done correctly and with patience, it will help players to reach their highest potential with minimised risk of injury and burn out. Strength training does not just jump from general to specific however. The process is gradual and may take place over several years. Such is the importance of this gradual progression, sample strength plans are provided for early post puberty players (i.e. ages 14 – 16) and late post puberty players (i.e. ages 16 – 18). Remember, it is biological and anatomical age that is important and not chronological age – hence the reason why there is overlap in the age categories. EXERCISE SELECTION Early post puberty players can incorporate challenging bodyweight exercise, such as pull ups and V sit ups into their routine. They can also make greater use of resistance machines and free weights exercises using low to moderate weights (that allow 10 repetitions or more). www.sport-fitness-advisor.com !93 Fit for Soccer - Junior Players Some low intensity plyometrics drills can also be included into the circuit. A plyometrics session with multiple sets of multiple exercises is not recommended at this stage. Players who are considered late post puberty and have reached maturation can emphasise free weights exercises such as squats, lunges, bench presses shoulder presses and pull downs. Players in this bracket can also use resistance machines freely. Also, more plyometrics exercises can be included into the program, which requires a separate session. The caveat is that players must have developed a solid strength base in previous years. If a player is only beginning a strength program for the first time, plyometric drills are not recommended. www.sport-fitness-advisor.com !94 Fit for Soccer - Junior Players What is Plyometrics? When a muscle is stretched before contraction it will contract more forcefully and rapidly (like an elastic band). This is basically what plyometric exercises do – they stretch muscles rapidly and then immediately demand a powerful contraction. It’s easier to imagine with an example from soccer… Imagine the jumping movement to win a header… The very first phase of this movement has to be a downward thrust. If you try jumping off the ground without first bending your knees, you’ll struggle to leave the ground. As you "dip" down just before a standing jump you are stretching muscle groups such as the quadriceps and hip extensors. These are the muscles that will contract very forcefully a split second later to produce the jump. The shorter and more rapid this downward movement or prestretching action is, the more forcefully those muscle groups can contract…. and the higher you will jump! Plyometric exercises help muscles to store and use energy rapidly, making them and the player more powerful! www.sport-fitness-advisor.com !95 Fit for Soccer - Junior Players STRENGTH TRAINING GUIDELINES (EARLY POST PUBERTY) Players who are considered early post puberty (i.e. 14 – 16) can continue with a circuit training format. However, more intense exercises can be added, including more free weights exercises with barbells and dumbbells. There is a danger that some early developers who are big for their age might be tempted, or encouraged, to start lifting heavy weights (loads greater than 75% one repetition maximum). Growth plates have not yet closed so the resistance should still allow 10 repetitions or more to prevent too much unnecessary strain. Lifting to failure or exhaustion on an exercise should still be avoided. A circuit can be made more difficult by increasing the number of exercise from 9 to 12, including more intense exercise stations, increasing the number of circuits and decreasing the rest interval time between exercise stations. Here are the parameters for circuit training in this group: www.sport-fitness-advisor.com !96 Fit for Soccer - Junior Players * Remember these are approximate guidelines for this age group. Individuals of the same age vary greatly in their development. Exercise should be prescribed based on biological rather than chronological age. If a circuit is performed as part of a longer group coaching session, it should be completed after technical and speed /agility work towards the end of the session. SAMPLE STRENGTH TRAINING SESSIONS (EARLY POST PUBERTY) Here are two sample circuit sessions for players in this age group. Many of the exercises are designed to work the muscle groups specifically used in soccer, however it’s important to www.sport-fitness-advisor.com !97 Fit for Soccer - Junior Players retrain some non-specific exercises in order to work and balance the entire body: www.sport-fitness-advisor.com !98 Fit for Soccer - Junior Players Unlike strength programs for the younger age groups, progression should now be a little more structured to accommodate the increase in intensity and volume. One effective way to do this is to use the stair-step method. The intensity and volume changes over a 4-week cycle, which can be repeated throughout the closed season and pre-season. www.sport-fitness-advisor.com !99 Fit for Soccer - Junior Players In the diagram above, week 1 is an easy week, weeks 2 and 4 are moderate and week 3 is difficult. The cycle repeats itself with week 5 being easy and so on. Remember though that week 5 may be slightly more difficult than week 1 as players will gradually adapt to the training load. Here’s how you can manipulate a circuit so it follows the 4-week cycle: WEEK 1 – 2 sessions, 2 circuits per session, 60 sec rest interval. WEEK 2 – 2 sessions, 3 circuits per session, 60 sec rest interval. WEEK 3 – 2 sessions, 3 circuits per session, 30 sec rest interval. WEEK 4 – 2 sessions, 3 circuits per session, 45 sec rest interval. www.sport-fitness-advisor.com !100 Fit for Soccer - Junior Players STRENGTH TRAINING GUIDELINES (EARLY POST PUBERTY) As players reach physical maturation, strength training should become predominantly soccer-specific. This means that exercises and intensities will reflect the nature and demands of the game. Soccer requires a combination of basic strength (to withstand challenges and hold up the ball), explosive power (for shooting, range of passing and sprinting) and muscular endurance (to repeat consecutive sprints, tackles, jumps and kicks without tiring). Unfortunately, it’s very difficult to train for strength, power and strength endurance all at once. Even in the fittest adult players it would quickly lead to over-training and fatigue. The solution is to use the concept of periodisation. Periodisation simply refers to the splitting up of a training plan into several distinct phases or periods. In soccer these phases are well known: Pre-season In-season Closed or off-season From a strength training point of view, the off-season and early pre-season is used to develop basic and maximal strength. Mid to late pre-season the program changes to convert this strength www.sport-fitness-advisor.com !101 Fit for Soccer - Junior Players into explosive power and strength endurance. During the inseason all 3 fitness elements are maintained as best as possible. Compensation is a phase of non-specific strength training. This is the kind of strength training that young players stick to all year round. Why is it important that older players include a phase of this non-specific strength training in their annual plan? It helps to redress some of the imbalances that can occur with sport-specific training and competitive soccer. The goal is balance the strength in the left and right side of the body and the agonists and antagonists (i.e. the hamstrings and quadriceps). It also provides the player with a welcome physically and psychological break. Use one of the circuit training programs outlined for early post puberty for the compensation phase. Explosive power and muscular endurance training are beyond the scope of this book. Although a sample explosive power routine is included below, please see the senior version of Fit For Soccer for detailed routines and guidelines. www.sport-fitness-advisor.com !102 Fit for Soccer - Junior Players Here are the parameters for basic strength training: * Remember these are approximate guidelines for this age group. Individuals of the same age vary greatly in their development. Exercise should be prescribed based on biological rather than chronological age. Although heavier weights can now be lifted by players who have reached physical maturation, loads should be kept under 80% one repetition maximum (80% 1-RM typically allows about 8 repetitions to be completed depending on the exercise). Even when players have stopped growing, it takes several months (sometimes years) of progressive strength training before maximal loads should lifted (over 85% 1-RM lifted for 5 repetitions or less). At least one cycle of an annual soccer strength program should be completed before moving on to heavy weights. www.sport-fitness-advisor.com !103 Fit for Soccer - Junior Players For detailed recommendations and advanced soccer strength training routines suitable for adult players, see the senior version of Fit For Soccer. SAMPLE STRENGHT TRAINING PLANS (LATE POST PUBERTY) BASIC STRENGTH PLAN This basic strength training program looks more like a traditional weight lifting routine with greater reliance on free weights and multiple sets of the same exercises performed back-to-back. However, a strength training plan for soccer bears little resemblance to a bodybuilding-type routine. Bodybuilders aim to isolate and exhaust every muscle group in order to bring about hypertrophy (increase in muscle size). Soccer players won’t necessarily benefit from increased muscle bulk. Neither will they benefit from working every muscle group to exhaustion. Strength training for soccer must take into account other elements of training, such as tactical and technical work plus endurance, speed and agility training. A suitable basic strength plan will develop strength in the major muscle group using the fewest number of exercises. Once this basic strength has been developed it can be converted into soccer-specific power in the next phase. www.sport-fitness-advisor.com !104 Fit for Soccer - Junior Players www.sport-fitness-advisor.com !105 Fit for Soccer - Junior Players www.sport-fitness-advisor.com !106 Fit for Soccer - Junior Players EXPLOSIVE POWER PLAN This following routine uses plyometric exercises to develop explosive power. When performed correctly plyometrics is safe and highly effective. However, there are some important guidelines players must adhere to if they are to get the best out of this form of training. GUIDELINES FOR PLYOMETRICS • A solid strength base is required before starting a plyometrics program. As a rule of thumb players should be able to squat twice their bodyweight or leg press 2.5 times their bodyweight. www.sport-fitness-advisor.com !107 Fit for Soccer - Junior Players • Warming up is crucial. Spend 10mins jogging or skipping followed by 5-10mins of stretching the muscles involved. • Extra sets and repetitions should NOT be added even if players feel like they haven’t worked very hard. Plyometric exercises are deceptively strenuous. • All lower body plyometric exercises should be performed on a firm surface that has some give such as grass or a synthetic running track. • Players should rest completely between sets, 3-5 minutes at least. Quality, not quantity, is all-important. • • Each action and each repetition should be performed with maximum speed, effort and proper technique. • For players new to plyometrics, keep session to under 100 ground contacts for any muscle group. • Do NOT use ankle or wrist weights for extra resistance. This will hinder the speed of the movement and increase the risk of stress injuries. • Instruct players to keep the torso erect during the movements -- it prevents undue strain on the lower back. • If any pain or discomfort is felt, the session should stop immediately. • Finally, don’t complete plyometrics and resistance training on the same day or when muscles are sore from a previous day’s training. www.sport-fitness-advisor.com !108 Fit for Soccer - Junior Players SAMPLE STRENGTH TRAINING EXERCISES (EARLY POST PUBERTY) LOWER BODY EXERCISES Medicine Ball Lunges 1) Start position: Stand with feet hip width apart.

Modern soccer is extremely fast and some of the top players almost resemble Olympic sprinters! But speed in soccer isn’t just about the ability to run fast. A “quick” player is one that can react quickly, accelerate sharply and produce several back-to-back sprints without tiring. Rarely, if ever, do soccer players reach top speed, so if a player isn’t blessed with the same genetics as Carl Lewis, all is not lost! Speed is definitely trainable and even a player who is considered naturally slow can, with the right conditioning program, become quick. One key point for parents and coaches to remember is that the greatest gains in speed come during puberty when muscle strength develops. It’s impossible to tell how fast a player will eventually become until after this stage. Also, the types of training that make the greatest difference (intense strength and explosive power training) cannot be completed until players have completely physically matured. Does that mean if a young, pre-adolescent player is considered slow that they simply have to sit around and wait? No, because even before puberty speed and agility can be improved. More importantly, some important foundations can be laid in the early years so that when a player does reach full maturity, they have greater potential for speed development. This section covers the various elements and drills important in speed for soccer. Sample programs are offered for the three different age categories as well as suggestions for progression during the season. www.sport-fitness-advisor.com !126 Fit for Soccer - Junior Players SPEED & AGILITY TRAINING PRE-PUBERTY (8-11 YEAR OLDS) Basic speed is a combination of strength, power and the ability to move limbs quickly. At this age, children lack strength and power and strenuous resistance training is not suitable. Therefore, the goal should be to increase a young player’s coordination and develop their neuromuscular system. This will help them to co-ordinate the actions of the arms and legs more efficiently, helping them to become quicker on the field. Agility training usually involves sharp twisting, turning and changes of direction. It also involves sudden acceleration and deceleration. But this is too strenuous for children in this age group and drills that emphasise these types of movements should be avoided until a later stage. Co-ordination is best developed through a wide variety of exercises, not all necessarily soccer-specific. This includes exercise for the upper body – an area that many coaches overlook and one that is crucial to foster well-rounded young athletes. SPEED & AGILITY TRAINING GUIDELINES Speed training drills, like all forms of training at this age, should be fun and varied. Ideally, they should be completed at the start www.sport-fitness-advisor.com !127 Fit for Soccer - Junior Players of a coaching session when players are fresh and can concentrate on the movements. Each drill should be kept short, lasting no longer than 4 – 6 seconds. Plenty of rest should be allowed between each drill so children don’t get fatigued in any way. Remember, the aim is develop co-ordination and this can only be done if players are fresh and raring to go. Start with distances of about 10 – 20 yards / meters, gradually progressing to 40 – 50 meters for children who are approaching puberty. Straight-line drills are more suitable for the youngest players in this group. Zigzag drills and slaloms and stop-start drills can gradually be added for older players in the age category. For the upper body, drills and games that use tennis balls and light medicine balls are ideal. Again, these do not have to be relevant to soccer and a variety of under arm, over arm and sideways movements should be included. www.sport-fitness-advisor.com !128 Fit for Soccer - Junior Players * Remember these are approximate guidelines for this age group. Individuals of the same age vary greatly in their development. Exercise should be prescribed based on biological rather than chronological age. SPEED & AGILITY TRAINING SESSION As with other forms of training, a structured and regimented plan should be avoided in young children. Coaching sessions are an ideal time to incorporate some speed drills. They can also be easily incorporated into a circuit or obstacle course as outlined in section two that can be completed in the back yard. Here are two sample speed training sessions for young soccer players: www.sport-fitness-advisor.com !129 Fit for Soccer - Junior Players www.sport-fitness-advisor.com !130 Fit for Soccer - Junior Players Gradual progression is the key to building healthy, injury-free young soccer players. Start with distance of 20 meters / yards in the youngest players (8-9 year olds) and over a period of 2 – 3 years, the distance can increase to 40 meters / yards (10-11 year olds). The types of drills (see below) can progresses from straight line running to zigzagging and slaloms. Regardless of age or experience, speed drills should always allow adequate recovery between repetitions. SAMPLE SPEED & AGILITY TRAINING DRILLS Drill 1 – Fast Arms • Players should be seated on the floor with the legs straight out in front of them. • Swing arms in a sprinting motion. Elbows should be kept at 90 degrees, close to the body and hands kept relaxed. • Hands should come up to about shoulder height and should go past the hips at the back. • Caution players not to bounce off of the floor as they swing their arms faster. Drill 2 – High Knees • Instruct players to stand in place with their feet hip width apart. • Jog on the spot with exaggerated high knees. • There should be minimal contact time with the ground and players should avoid landing on their heels. • Keep this drill to 5-10 second bouts as it can be quite tiring for young players. www.sport-fitness-advisor.com !131 Fit for Soccer - Junior Players Drill 3 – Modified Skipping • Start with both feet together and begin by driving your left leg into the air and explode with the right foot so that both feet are off the ground. • Upon landing bring the left foot down and drive the right leg into the air and repeat. • Swing arms back and forth during skipping motion. • Continue this alternating motion until desired repetitions are met. Drill 4 – Carioca This is quite a difficult drill for athletes of any age to pick up. But once learnt is simple to complete and is excellent for developing co-ordination and rhythm. • Step to the left with left leg and immediately bring right leg over and in front of the left leg and place it onto the other side of left foot. • Step to the left again with the left leg and immediately bring right leg over and behind the left leg. • Continue to repeat this alternating pattern for10-20 meters/ yards. • Have players practise in both directions. www.sport-fitness-advisor.com !132 Fit for Soccer - Junior Players Drill 5 – Single File Relay Equipment: cones • The group is organised into two or more single files of up to 10 players. • On the coach’s command the first player in line must run to a cone 10 – 20 meters / yards in front of them, around it and then back. • The next player in line cannot go until they touch hands with the returning player. • The returning player always goes to the back of the line. Variations: add variety to this drill by giving the players objects to carry and pass to one another such as several tennis balls, hoops and bean bags. Set up a small task they must complete at the cone such as star jumps, throwing a ball back to the coach or throwing a tennis ball into a box etc. Drill 6 – Slalom Relay Equipment: cones • The group is organised into two or more single files of up to 10 players. • On the coach’s command the first player in each line must weave in and out of a line of cones 1-2 meters / yards apart. • The furthest cone should be about 10 – 20 meters/yards away. • The next player in line cannot go until they touch hands with the returning player. • The returning player always goes to the back of the line. Variations: similar variations as the drill above can be used for the slalom relay. Have the players dribble a soccer ball or bounce a basketball around the cones. Remember at this age it is important to include a wide variety of skills to help develop general speed and co-ordination. Drill 7 – Obstacle Relay Equipment: cones, low boxes / hurdles • One or more straight line obstacle courses up to 40 meters/yards in length should be set up (see diagram below). • The group is organised into two or more single files of up to 10 players. • On the coach’s command the first player in each line must complete the obstacle course and return to the back of their line. • The next player in line cannot go until they touch hands with the returning player. www.sport-fitness-advisor.com !133 Fit for Soccer - Junior Players Keep the course simple with obstacles low enough that players can run over them. Players should not leap or hop over obstacles. The aim of this drill is to promote quick foot speed and co-ordination of steps between obstacles. Drill 8 – Circles • The group is organised into circles of up to 10 players. • Each player is given a number. • The coach shouts out two random numbers and the two corresponding players must run clockwise around the outside of their circle and back to their original position. • This drill is designed to develop both focus and reaction time. Drill 9 – Tents & Campers Equipment: cones, low boxes / hurdles • The group is organised into pairs who then form a large circle roughly 15-20 meters/yards in diameter. • One of the pair stands with their feet apart (tent) and the other crouches in front of the tent (camper). • The coach shouts “tents” or “campers” and the appropriate partner runs clockwise around the outside of the circle and back to the starting position. • Like the drill before, this drill is designed to improve focus and reaction time but it also adds an element of different starting positions. Variation: the coach can call out various words beginning “C” and “T” to try and catch the players out. Any player moving on any words other than “tents” or “campers” has to sit out a round. www.sport-fitness-advisor.com !134 Fit for Soccer - Junior Players Drill 10 – Go… Stop… Go… Stop • The group is spread out across a large area. The coach stands in the • • • • • middle so that all players should be at least 20-30 meters/yards away. The coach shouts “Go” and all players run towards the coach. The coach then shouts “Stop” and players must freeze on the spot. The coach continues to shout “Go” and “Stop” and the first player to reach the coach gets to be the caller. Any player still moving after “Stop” has to sit the next call out so will fall further behind. This drill helps to develop both acceleration, deceleration and reaction time. Variation: use different words instead of “Go” and “Stop” or call out words beginning with “G” and “S” to catch players out. www.sport-fitness-advisor.com !135 Fit for Soccer - Junior Players SPEED & AGILITY TRAINING PUBERTY (11-15 YEAR OLDS) With puberty comes a natural increase in strength and power. This translates to increased speed and also the ability to tolerate more demanding activities. Although players in this age bracket can, and should, follow a resistance training program (see section 2), speed development should still come predominantly from drills designed to improve co-ordination and agility. Intense strength and power training can have a dramatic affect on speed but this type of training is not suitable until players have matured fully. Similar to this, all out sprint training that requires maximal, explosive efforts over distances of more than 30 meters/yards should be reserved only for older players in the age group. However, more soccer-specific drills that include twists, turns, shuffles and decelerating quickly can now be introduced. SPEED & AGILITY TRAINING GUIDELINES As players grow stronger, they will be capable of more forceful and explosive movements. To make best use of this, speed and agility drills are best completed at the beginning of a coaching session (after a thorough warm up) when players are at their freshest. www.sport-fitness-advisor.com !136 Fit for Soccer - Junior Players Drills can increase to up 50 yards / meters now but adequate rest to allow complete recovery is still essential. Exercises to improve reaction time should also be included into the program. At very young ages, children lack the concentration to benefit from this form of training but as they mature it’s an important part of their all-round athletic development. Speed and agility drills should consist of exercises both with and without the ball at the feet. While drills that include a ball obviously translate directly to game situations, drills without a ball help players to concentrate fully on the movements and maximise their effect. Exercises to improve speed in the upper body should not be neglected. * Remember these are approximate guidelines for this age group. Individuals of the same age vary greatly in their development. Exercise should be prescribed based on biological rather than chronological age. www.sport-fitness-advisor.com !137 Fit for Soccer - Junior Players SAMPLE SPEED & AGILITY TRAINING SESSIONS This sample speed session can be completed 2-3 times per week at the start of soccer coaching sessions. It includes basic straight-line speed drills, drills with changes of direction and drills with and without a ball. You could also include some of the technique drills in the 8 – 11 category as part of the warm up or change some of the straightline drills for a relay. Here are two sample speed and agility drills for players in this category: www.sport-fitness-advisor.com !138 Fit for Soccer - Junior Players www.sport-fitness-advisor.com !139 Fit for Soccer - Junior Players SAMPLE SPEED & AGILITY TRAINING DRILLS Drill 1 – Alternating Starts The basis of these speed drills is a 10 – 20 meter/yard sprint. Players should focus on accelerating as quickly as possible by powering away with the arms and legs for the first 5 meters/yards. In large groups 2 or 3 players can run against each other. Alternate the start for each successive sprint to make the drill more soccer-specific and to add variety. Here are some ideas: • Do 1-3 push ups, squat thrusts or burpees and then sprint • Start by kneeling, lying face down, sitting on hands (which can’t be used • • • • to get up) and then sprint Do 5 keep ups or 5 ball touches and sprint Have some one throw or pass your the ball for you to control and lay off and sprint Run backwards for 5yards and turn and sprint Touch left hand down, touch right hand down, jump to head the ball and sprint Variation: At the end of the sprint a feeder can pass or throw a ball for the player to control and pass back. This will help to develop deceleration as well as composure with the ball after a quick run. Don’t be fixated with making players pass or control the ball with their feet. A ball can be thrown to catch with a push-pass back to the feeder for example. www.sport-fitness-advisor.com !140 Fit for Soccer - Junior Players Drill 2 – Shuffle Relay Equipment: cones • The group is organised into two or more single files of up to 10 players with a series of cones set out in front of them (see diagram right). • On the coach’s command the first player in line must run to the first cone, side-step to the right then back to the left facing the same way before running to the next cone. • The player then turns and repeats the course in the opposite direction. • The next player in line cannot go until they touch hands with the returning player. • The returning player goes to the back of the line. Variations: add variety to this drill by giving the players objects to carry and pass to one another such as several tennis balls, hoops and bean bags. Set up a small task they must complete at one of the cones such as star jumps, heading a ball back to the coach etc. Drill 3 – Alternating Stride Length Equipment: cones • Set up a series of cones in a straight line. • The first 10 cones should be about 1 meter/yard apart. • The next 10 should be 2 meters/yards apart. • From standing start players sprint the total length of the cones taking one step between each marker. • The cones close together will encourage faster, shorter strides. • Players should walk slowly back to the start to recover. www.sport-fitness-advisor.com !141 Fit for Soccer - Junior Players Drill 4 – Speedy Feet Equipment: cones, soccer balls • Split the group into pairs. Each pair has three soccer balls. • One ball is placed in front of the working player, one to the left and one to the right no more than 1 meter/yard away. • The other player gives each ball a name or number and calls out a series of commands. For example, the caller might give the command “one, three, two, one”. Alternatively, they might shout “Queen, King, King Queen, Jack”. • The working player must touch the top of each ball with both feet (alternately, not jumping onto the ball) in the order of the command. • The working player rests for 30 – 60 seconds and then repeats following a different command from the caller. www.sport-fitness-advisor.com !142 Fit for Soccer - Junior Players Drill 5 – Basic Ladder Drill Equipment: agility ladder • Start with your feet hip width apart at the bottom of the ladder. • Jump up with both feet and land on the left foot only in the first square • Immediately push off with your left foot and land with both feet in the second square. • Immediately push off with both feet and land on your right foot only. • Push off from your right foot and land on both feet. • Repeat this pattern for the full length of the ladder. Agility ladders are excellent for improving foot speed, co-ordination and overall quickness. They can cost anywhere from $30 for shorter ladders to over $100 for more elaborate designs. An alternative is to either make your own with some white parcel string and a few soccer net pegs (make sure the pegs are pushed flush into the ground). Alternatively, you can paint a simple ladder pattern on grass with some white wash or use white adhesive tape (masking tape). Each section of the ladder should be about 1.5 feet square and ten sections is ample. Drill 6 – Lateral Ladder Drill Equipment: agility ladder • Start with both feet outside of the first square and to the left. • Step into the first square with your left foot first, immediately followed by your right foot... in a 1-2 motion. • Step to the right, outside the first square again with your left foot fist, followed by your right. • Now step diagonally left into the second square, with the left foot leading always keeping the same 1-2 motion. • Now step out to the left-hand side of the second square and repeat for the full length of the ladder. www.sport-fitness-advisor.com !143 Fit for Soccer - Junior Players Drill 7 – Follow The Leader Equipment: cones • Mark out an area about 10 meters/yards by 10 meters/yards. • In pairs, one player runs randomly within the marked area. The other player must follow maintaining no more the 2 meters/yards distance. • The leader should be changing direction and pace constantly. • Two or more sets of pairs can be added to the area so players must be conscious of what’s around them. Drill 8 – Reaction Time Starting Cues You can help to improve reaction time by varying the starting cues for any of these drills. For example, the coach can shout “Go” or stand behind players out of sight signalling the start with a clap or whistle. These are auditory cues and develop different reactions than visual cues. Alternatively, you can use a visual cue such as a lowering of the arm, or a kinaesthetic cue such as a tap on the shoulder. For younger players it is best to combine both visual and auditory cues. www.sport-fitness-advisor.com !144 Fit for Soccer - Junior Players SPEED & AGILITY TRAINING POST PUBERTY (15-18 YEAR OLDS) Speed training can have its more dramatic effect following puberty. Players are able to tolerate more physically demanding drills and speed work can be coupled with explosive strength and power training. At this age, speed training should become soccer-specific. Drills should mimic the demands and movement patterns in a game. All out sprints with maximal effect, as well as sharp turns, twists and changes in direction should be included in the program. Training also becomes more formal and this means that players may want to complete speed sessions and drills away from team training sessions. SPEED & AGILITY TRAINING GUIDELINES The best way to improve a player’s speed is with all-out maximal efforts. This conditions the neuro-muscular system so that the greatest number of motor units can be activated in the shortest period of time. Key to the success of speed drills in this age group is the rest interval in between each effort. Is should be long enough to www.sport-fitness-advisor.com !145 Fit for Soccer - Junior Players allow complete recovery. Unlike endurance training where the aim is to bring about fatigue, speed drills must be completed in a rested state so that the greatest amount of effort can be exerted. As a rule of thumb stick to a work to rest ratio of 1:5. For example, a five second sprint should be followed by at least twenty-five seconds active recovery. Speed drills should always be completed at the start of a training session. Soccer is rarely played in straight lines, and while straight line sprinting will improve basic speed, agility drills must be included to improve a player’s ability to change direction quickly. These drills should also be completed with maximal effort and adequate rest intervals. It’s important to incorporate drills with and without a ball. Sprinting without a ball improves speed to its greatest extent and this can be converted to soccer-specific speed with drills that use a ball. www.sport-fitness-advisor.com !146 Fit for Soccer - Junior Players * Remember these are approximate guidelines for this age group. Individuals of the same age vary greatly in their development. Exercise should be prescribed based on biological rather than chronological age. As players reach full maturity their training plans can and should adopt the principle of periodisation. Recall from previous chapters that this means dividing the overall program (usually 12 months long) into several distinct periods or phases. As with other forms of training, speed training changes over these phases. Here are the four most relevant phases to soccer that you are probably already familiar with: Early Pre-Season: No speed & agility work should be completed. Late Pre-Season: 1 – 2 (maximum 3) speed & agility sessions a week. In-Season: 1 – 2 speed & agility sessions a week. Closed Season: No speed & agility work should be completed. www.sport-fitness-advisor.com !147 Fit for Soccer - Junior Players You may use different terms such “off season” instead of preseason or “competition season” instead of in-season, but the principle remains the same. SAMPLE SPEED & AGILITY TRAINING SESSIONS www.sport-fitness-advisor.com !148 Fit for Soccer - Junior Players www.sport-fitness-advisor.com !149 Fit for Soccer - Junior Players SAMPLE SPEED & AGILITY TRAINING DRILLS These drills are more intense and not suitable for younger age groups. However, speed & agility drills from the other age category can be adapted and used in older players. Drill 1 – Alternating Starts The basis of these speed drills is a 10 – 20 meter/yard sprint. Players should focus on accelerating as quickly as possible by powering away with the arms and legs for the first 5 meters/yards. In large groups 2 or 3 players can run against each other. Alternate the start for each successive sprint to make the drill more soccer-specific and to add variety. Here are some ideas: • Do 1-3 push ups, squat thrusts or burpees and then sprint. • Start by kneeling, lying face down, sitting on hands (which can’t be used • • • • to get up) and then sprint. Do 5 keep ups or 5 ball touches and sprint. Have some one throw or pass your the ball for you to control and lay off and sprint. Run backwards for 5yards and turn and sprint Touch left hand down, touch right hand down, jump to head the ball and sprint. Variation: At the end of the sprint a feeder can pass or throw a ball for the player to control and pass back. This will help to develop deceleration as well as composure with the ball after a quick run. www.sport-fitness-advisor.com !150 Fit for Soccer - Junior Players Drill 2 – Hollow Sprint with Ball Equipment: cones • Set up five markers about 20 meters/yards apart. • Place a ball at marker 2 and marker 4. • Starting on marker 1, players sprint to marker 2, dribble the ball to marker 3, sprint to marker 4, dribble the ball to marker 5. • Players then walk back to the start replacing the balls at cones 4 and 2 as they do. Note: To make this drill work for a larger group, simply add an extra marker to one end and have two equal groups at either end. A player from group A performs the drill leaving the balls at markers 3 and 5. They join the back of group B. The first player from group B performs the drill by sprinting from marker 6 to marker 5 and so on, leaving the balls at markers 4 and 2. They then join the back of group A. See the diagram below. www.sport-fitness-advisor.com !151 Fit for Soccer - Junior Players Drill 3 – Liverpool Sprints Equipment: cones • Set up a series of cones about 20 meters/yards apart in a circle formation • (see diagram below). • Place two players on each cone. On one cone only there should be six players. This is the starting point. • In the group of six, four players sprint to cone 1. When they reach cone 1 the back two players wait at cone 1 while the front two players carry on to cone 2. They are also joined by the two players originally at cone 1. • In effect, each pair sprints the length of two cones and rests. This is continued right around the circle. www.sport-fitness-advisor.com !152 Fit for Soccer - Junior Players Drill 4 – Hurdle Relay Equipment: cones, hurdles, soccer balls • Divide the group into two teams. • Set up a course according to the diagram below. • Two sets of hurdles are placed 10 meters/yards outside the penalty area. • Group A are designated attackers and group B defenders. A ball is placed on the edge of the goal area. • On the coaches command, a player from each team sprints to the first hurdle, jumps it, sprints to the next hurdle and under it before sprinting to a ball on the edge of the box. • If the defender wins they clear the ball. If the attacker wins they shoot at goal. www.sport-fitness-advisor.com !153 Fit for Soccer - Junior Players Drill 5 – Agility T Drill Equipment: cones • Set up a series of cones similar to the diagram below. • Divide the group into pairs. One player acts as the server (yellow). • The working player (blue) starts by sitting down cross-legged. • The drill begins with the server throwing the ball for the working player to get up quickly and volley back. • They immediately side-step to the right and back to the centre cone. The server should throw the ball for them to knee or chest back. • Te working player immediately side-steps to the left and back. The server should bounce the ball for them to pass back. • The working player then runs backwards and returns to the centre cone this time to head the ball back to the receiver. Change places. www.sport-fitness-advisor.com !154 Fit for Soccer - Junior Players Drill 6 – Tango Ladder Drill Equipment: agility ladder • Start with both feet outside of the first square and to the left. • Cross your left leg over your right and into the centre of the first square. Your right leg should immediately follow to the right of the first square, followed by your left leg. • It's a 1-2-3 motion like you're dancing. • From here your right foot comes across your left and into the centre of the second square as the pattern is repeated in the opposite direction. • Repeat for the full length of the ladder. www.sport-fitness-advisor.com !155 Fit for Soccer - Junior Players SECTION 5 FLEXIBILITY TRAINING FOR JUNIOR PLAYERS ports fitness advisor www.sport-fitness-advisor.com !156 Fit for Soccer - Junior Players Flexibility is perhaps the most neglected, and under-valued, component of fitness. In soccer, particularly at the junior level, a few token stretches are usually reserved for the warm up at best. But with just a little more attention, a well-designed stretching program can pay great dividends right throughout a young player’s career. In any sport, good range of motion is required to execute skills and complex movements with precision. In soccer, volleying a ball above waist height is just one example. Lunging to intercept a pass or make a tackle are two more. Of course flexibility training, not just as part of the warm up, helps to prevent injury. Muscle strains and tears have been associated with muscle tightness, and muscle tightness is often the result of repetitive movements through a limited range of motion. Soccer is quite unbalancing on the body. The same muscles are used in the same patterns over and over again and a good stretching program will help to address this. The rest of this section covers the different types of flexibility important to young soccer players, as well as various types of stretching programs. You’ll also find sample warm up and cool down routines and how you can best incorporate stretching before and after a match. TYPES OF STRETCHING There are several methods for improving flexibility. Three of the most common are: www.sport-fitness-advisor.com !157 Fit for Soccer - Junior Players Static stretching PNF stretching Dynamic stretching Each has their advantages and disadvantages and some are not suitable for very young players. Static Stretching Static stretching is an effective way to increase flexibility and range of motion about a joint. It is suitable for all ages and involves holding a stretched position, without moving, for a given time. Static stretching is best completed when muscles are warm with an increased blood flow. This makes them an ideal choice after a match or training session. Just two or three session per week is enough to significantly increase range of motion. Static stretching may be detrimental if it’s performed before a match. Some studies show that it can negatively affect speed and power in certain situations and does little to prevent injury. However, the research is still inconclusive, especially in younger players. A good warm up routine is covered later in this section and uses a different type of stretching (dynamic stretching) to prepare players for a game or training session. PNF Stretching Some coaches believe that PNF stretching is even more affective that static stretching, when it comes to increasing flexibility. PNF stretching requires a partner to apply force to the limb being stretched, and this sometimes makes it lengthy and impractical www.sport-fitness-advisor.com !158 Fit for Soccer - Junior Players for soccer teams. PNF stretching is also not recommended for pre-adolescent players. It’s best use in soccer may be part of a rehabilitation program following injury. A long period of inactivity can quickly and severely reduce flexibility and PNF stretches can speed the return to full fitness. PNF should not be completed prior to a match or training session by any age group. Dynamic Stretching A dynamic stretch involves flexibility during sport-specific movements. Unlike static and PNF stretching where the position is held for a number of seconds, dynamic stretching uses movement. A good example is a leg swing back and forth. This mimics the action of kicking a ball and if the movement is exaggerated it will stretch the muscles of the hip joint, quadriceps and hamstrings. Unlike static and PNF stretching, dynamic stretching won’t bring about long-term changes in flexibility. What it will do however is relieve and reduce muscle tightness. This makes it an ideal component of a warm up and it is likely to prevent muscle tears and pulls to a greater extent than traditional static stretches. Dynamic stretches are also useful at the end of a cool down, helping to flush out any blood that has pooled in the muscles after an intense training session. As with static stretching, dynamic stretches can be used by players of all ages. www.sport-fitness-advisor.com !159 Fit for Soccer - Junior Players STRETCHING FOR ALL AGES Regular stretching is important in every age group – from eight years old to eighteen and over. Although young children are naturally supple, flexibility training should still be encouraged so that they form good habits early on. During and after puberty, boys in particular lose flexibility due to an increase in muscle size, strength and stature. Proper stretching to all the major muscle groups can help to offset this and may help to prevent many of the overuse injuries associated with rapid growth sports. As players mature, flexibility training should progress gradually. At first, stretches can be held for longer and after puberty more demanding types of stretching can be included. The table below offers guidelines for stretching at various ages: www.sport-fitness-advisor.com !160 Fit for Soccer - Junior Players STRETCHING ROUTINES TO INCREASE FLEXIBILITY The following three static stretching routines are designed to increase a player’s range of motion over the long-term. The stretches are specific to soccer and are best completed after a training session, after a match or following at least ten minutes of light, cardiovascular exercise. The best time to increase flexibility is during the closed season and early pre-season. Ideally, this requires about three to five sessions per week. Gains made can be maintained during the competitive season with just two to three sessions per week. Younger players pre-adolescents can complete two to three sessions per week all year round. It’s important to watch that young players don’t try to compete in anyway with each other as to who can stretch the furthest. Emphasize the point that stretching should not be painful in anyway and to stop if it is. www.sport-fitness-advisor.com !161 Fit for Soccer - Junior Players STRTCHING ROUTINE PRE-PUBERTY (8-11 YEAR OLDS) Complete each of the following stretches twice before moving onto the next.

Slide your arms further away and slowly shift your hips back towards your feet until a comfortable stretch is felt. 3. Hold for 20-30 seconds. Repeat as prescribed. WARMING UP www.sport-fitness-advisor.com !174 Fit for Soccer - Junior Players A warm up helps prevent injuries such as muscle strains and pulls. It also helps to prepare players mentally and get into the right frame of mind. The warm up at every age, should consist of two parts: General Warm Up – this consists of five to ten minutes of light, cardiovascular exercise to increase blood flow to muscles and raise body temperature. The can include jogging with a ball but intricate dribbling should be saved until later. Specific Warm Up – this consists of movements similar to that in a game. For older players, twisting and turning drills that emphasise sharpness are important. All age groups should work with the ball even if it is just simple passing and controlling to get accustomed to the pitch surface. Dynamic stretches should also be included. Static stretches are best left until after the game. Sample Warm Up Routine 1. Start with 5 – 10 minutes of light jogging across the pitch. Include occasional jumps, sidestepping, cariocas, jogging backwards etc. 2. Five minutes of basic passing, controlling and dribbling. Avoid drills where players will be standing around for long periods. www.sport-fitness-advisor.com !175 Fit for Soccer - Junior Players 3. Complete some soccer-specific dynamic stretches. For each of the stretches below complete 10 – 20 repetitions: Stretch 1 – Arm Swings & Circles Standing with feet shoulder width apart, extend the arms out to the sides and then bring them across the chest. This stretches the chest and shoulder muscles. Another good upper body dynamic stretch is to make large circles again crossing the arms in front of your body. Stretch 2 – Side Bends This stretch loosens the torso and upper back muscles. Place one hand by your side and the other above your head. Reach down to one side as far as is comfortable and then immediately repeat to the other side switching the position of your arms as you do. Stretch 3 – Carioca This stretch helps the muscles surrounding the hip joint and the lower back to release. Moving in a sideways direction start by putting your right leg across your left (as in the diagram). The next step is with your left foot to the side. Now step with your right leg behind your left leg. The result looks something like a salsa www.sport-fitness-advisor.com !176 Fit for Soccer - Junior Players dance! Stretch 4 – Funny Walk To stretch the hamstrings dynamically walk without bending the knees, attempting to touch each foot with each stride. Stretch 5 – High Knees To stretch the hip extensors dynamically, walk bringing the knees as close to the chest as possible. Stretch 6 – Walking Lunges This stretch is superb for stretching the hip flexors which can become tight in soccer players. With hands clasped behind your head walk with an exaggerated lunging movement. Be sure to keep your trailing knee off the floor. Stretch 7 – Inside Leg This stretch is very similar to static adductor stretch above. The difference is that the stretch is not held in position. Instead shift your weight from side to side (without bouncing) so that the left leg is stretched then the right and so on. Older players (15+) can complete some short, sharp sprints with changes in direction. Emphasise quality and sharpness other than quantity. The idea is to avoid leaving the players fatigued. Time the end of the warm up so that there is no longer than five minutes before the start of the game. www.sport-fitness-advisor.com !177 Fit for Soccer - Junior Players COOLING DOWN Cooling down for 10 – 15 minutes after a heavy training session or tough game has several benefits: • Gradually reduces heart rate back to resting levels. • Helps to flush out blood that has pooled in the muscles taking • • the burden off the heart.
