Nearly all athletes can benefit from the services of a performance enhancement specialist. The trainer can help athletes develop consistent habits in their training, motivate them, give them a scientifically structured training and nutrition program, and integrate the many aspects of the program into a cohesive strategy to improve performance. Performance enhancement specialists possess an impressive array of training, nutritional, and psychological tools to help athletes excel. At the same time, coaches in high school, college, and sports clubs unfortunately are often poorly trained because of the sorry state of coaching education in many American colleges and universities. This presents opportunities for performance enhancement coaches to fill the void and to help motivate athletes to “be the best they can be” on and off the playing field. The performance enhancement specialist must have the scientific and practical knowledge to help people improve their fitness and achieve the level of performance they want. This process involves determining the client’s goals, identifying the sport’s requirements, assessing fitness and physical capacity, and designing a program to help the client achieve his or her goals. Performance enhancement coaches with specialized knowledge in performance enhancement are invaluable at all levels. They can teach high school athletes the principles of training for strength, power, and endurance. They can help prepare college or professional athletes for the high demands of elite sport—often determining whether or not they make the team. Trainers can also help the “average” person reach higher levels of performance in recreational tennis, skiing, master’s sports, league basketball, softball, and bodybuilding, to name just a few. The trainer also can be a motivating factor helping people maintain a healthy lifestyle involving regular exercise, proper nutrition, reduced stress, and the reduction of disease risk factors. Working with the average person is often the bread and butter for the performance enhancement coach. America faces an obesity epidemic. The Centers for Disease Control and Prevention (www.cdc.gov/) reported that 66% of Americans are either obese or overweight. About 50% of people are physically inactive and could benefit from the services of a qualified performance enhancement coach. Special populations also are potential clients— even for the performance enhancement specialist. People with diabetes, asthma, spinal cord injury, amputation, or cerebral palsy or who are developmentally disabled will benefit from the services of a knowledgeable trainer. Families of these people may have discretionary income that will pay for your services. You could help these people improve their physical capacities for sport or health and well-being.

Sports Performance Enhancement Strength and conditioning specialists who work with serious athletes must be more than good athletes themselves. They must have detailed knowledge of fitness assessment, specific sports, and exercise program development, including general knowledge of anatomy, physiology, exercise physiology, biomechanics, sports training, pharmacology, sports psychology, and sports nutrition. They must know the science behind training, diet, supplements, and psychology. Just as important, they should understand the “art” behind blending these elements in a way that works for the athlete. "½Ĭ·§ĦÝăúƔ§ĝÝ·y·ÝÄúĦÝŌ·KúăĻòĽÓÄƕ ēēòÝĽy·ÝÄúĦÝŌ·KúăĻòĽÓÄ Ideally, a performance enhancement specialist should have a college degree in kinesiology, physical education, or physical therapy. The combination of a general education, training in basic sciences (anatomy, physiology, chemistry, and physics), and a theoretical and practical knowledge of exercise physiology, biomechanics, nutrition, pharmacology, pathophysiology, sport psychology, motor learning, and motor development provide invaluable insight and understanding for long-term client development. Performance enhancement specialists should have adequate academic preparation so they know why they should prescribe specific exercises and training programs. A UCLA study of 115 experienced personal trainers showed only 42 % passed a test of fitness knowledge! The trainers were employed in health clubs, colleges, or private practices. Almost all trainers with specialized college degrees passed. Disappointingly, 44 % of trainers with five or more years of experience failed the test. The most knowledgeable trainers had a college degree and a proper certification as a personal trainer. Degree programs are available at most universities and community colleges. ISSA currently offers an associate’s degree in exercise science with a specialization in personal training and is moving toward establishing a bachelor’s degree program in the not so distant future. Essential Knowledge for the Specialist in Sports Performance Enhancement | 5 Anatomy and Physiology: Every performance enhancement specialist should have a thorough understanding of anatomy and physiology. There is just no way around this. Anatomy describes body structures. You should know the major muscles and their actions. You cannot strengthen healthy or injured muscles unless you know where they are and what they do. Joints are complicated structures containing delicate lubrication systems and unique tissues. Understanding them will help you prevent life-long injury and disability and contribute to long-term health. A basic knowledge of the structure and function of the brain, bone, heart, liver, kidneys, lungs, blood vessels, muscle, and skin will help you understand their roles in health, disease, and performance. Performance enhancement specialists should have a comprehensive understanding of metabolism—the sum total of the chemical reactions occurring in the body. During metabolism, the body converts food energy into other forms of energy the body can use at rest and during exercise. The physically fit athlete is an efficient energy manager. Physical training improves metabolic capacity. The knowledgeable performance enhancement specialist can improve the metabolism without causing overtraining or injury. Exercise and nutrition interact to influence metabolism and its adaptability. Know the function and regulation of the lungs, heart, and blood vessels. Knowledge of the structure and function of the cardiorespiratory system will help you understand the basis for aerobic capacity, metabolic health, and cardiovascular disease. A high capacity cardiorespiratory system is important for health and performance—even in high-power athletes. Athletes such as throwers and weightlifters must have good cardiovascular capacity necessary to endure long practice sessions. In sports such as American football, soccer, volleyball, and water polo, cardiovascular fitness can mean the difference between winning and losing. For the average person, a high capacity cardiorespiratory system is vital for health and longevity. Performance enhancement specialists should also understand the function of hormones and their effects on metabolism. Hormones are critical for maintaining muscle and bone mass with age and for maximizing the effects of training and nutrition. Some athletes take banned hormones such as human growth hormone, testosterone and other anabolic steroids, and erythropoietin (EPO). Trainers should understand how these substances work and be aware of alternatives involving training and nutrition. A working knowledge of genetics is essential for the modern performance enhancement specialist. The human genome was identified more than 10 years ago. Since then, scientists have found variants of genes that control endurance, strength, speed, and psychological characteristics. Trainers should understand the benefits and limitations of specific gene variants and how they influence the training process. performance enhancement specialists should understand the brain and nervous system. New and exciting tools such as PET, MRI, and CT scans have enabled us to learn about this previously little understood area of physiology and function. Trainers should understand the influence of trauma on brain function and long-term health. They should also understand International Sports Sciences Association 6 | Unit 1.1 the importance of precise motor patterns in the nervous system that dictate how we learn and perform motor skills. Principles of Training: Trainers should have strong knowledge of the physical and psychological adaptations to training. Changes in training status improve fitness and capacity of the physiological systems. Knowledge of muscle, cardiopulmonary, and metabolic physiology, and how they adapt to training, is critical for any strength and conditioning specialist. Strength and conditioning coaches must understand basic principles of fitness training such as overload, specificity, whole-body functional training, individual differences, reversibility, periodization, rest, overtraining, and stimulus variability. Trainers should also know how to achieve training effects quickly, efficiently, and without injury. Development of Health and Performance Fitness Components: It is difficult to separate health- and performance-related physical fitness. Certainly they overlap. For simplicity, health-related fitness components include endurance, strength, muscular endurance, flexibility, and body composition. Performance-related fitness includes all of the above including power, agility, speed, balance, and skill. The knowledgeable strength and conditioning specialist should understand the physiology of each fitness component and know training techniques to develop them in athletes and physically active clients. Sports Nutrition: Nutrition supplies the energy required for growth and fuels metabolism during exercise. Twenty years ago, the best advice a coach could give a young athlete was to “eat a Sports Performance Enhancement well-balanced diet containing a variety of foods.” This remains good advice. In addition, sports scientists have developed many nutritional techniques to improve performance. Sports drinks, dietary composition, nutrient timing, and some dietary supplements can boost performance under a variety of circumstances. Strength and conditioning specialist, particularly strength and conditioning specialists, should be able to design diets for athletes that consider the nutritional needs of intense training and provide the essential nutrients to improve performance. Some states have laws regulating nutritional counseling, so be aware of the requirements in your area (www.nutritionadvocacy.org). Measurement: Strength and conditioning specialists should use scientific methods if they want to remain effective. This involves using valid measurement tools to measure weaknesses in fitness and improvements in the training program. You should know basic tests to assess fitness in the most common health and performance components and relate them to performance in the athlete’s sport. You should become familiar with the basic statistical terms mean, standard deviation, percentile rank, correlation, and regression. These terms are important for interpreting the research results you read in journals and articles. Motor Learning: Motor learning involves the study of how people learn physical skills. Strength and conditioning coaches attempt to improve fitness that can be transferred to faster and more powerful sports performances. Strength and power transfer is automatic. Simply increasing the amount of weight an athlete bench presses or squats does not automatically Essential Knowledge for the Specialist in Sports Performance Enhancement | 7 improve power in football, track, or basketball. The newly acquired strength must be integrated into the specific sports movements. Strength and conditioning coaches should understand how athletes best learn sports skills and how specific training exercises affect learning them. Psychology of Sport: Success in sport or an exercise program requires dedication and motivation. Strength and conditioning coaches can help athletes succeed by believing in them, helping them focus on goals, and providing them with concrete methods to improve performance. Intense training is difficult for athletes at any level. The trainer can help athletes maintain a balanced “good” life. Strength and conditioning coaches must know enough about sports psychology to help athletes cope with the stresses of sport and some stresses unrelated to sport. You can help them keep sport in its proper perspective and ensure that training for athletics remains a healthy, positive experience. Prevention and Treatment of Athletic Injuries: A fine line often separates improved fitness from training and breakdown and injury from overtraining. The strength and conditioning specialist must know how much training causes positive adaptation and how much is excessive. Injuries do occur in sports. Part of your job as a strength and conditioning coach is to work around the injury to maintain fitness or at least to prevent deterioration. You should also know basic rehabilitative exercises for major injuries and the important role of conditioning in injury prevention. Strength and conditioning coaches must know emergency medical procedures in the unlikely event an athlete suffers a serious medical condition or injury. You must keep meticulous records of your injury management procedures to protect yourself from a lawsuit. oĖ§·ĦÝ·§ò"ŀēÄĖÝÄú·ÄƔĦÙòÄĦÝ·ĝƕ Coaching, and Training "ŀēÄĖÝÄú·Ä Strength coaches should walk the walk. It’s nearly impossible to teach the nuances of Olympic lifts, plyometrics, power lifts, kettlebell exercises, and functional training if you can’t perform the exercises. Learning these exercises takes thousands of hours of practice. If all your knowledge comes from a book, you “don’t know what you don’t know.” You will gain valuable and unique experiences from academic preparation, participating in athletics, coaching, and continuing education. The blend of theory and practice is essential for any trainer. The strength and conditioning specialist who is all theory won’t have the practical experience necessary to influence athletes and clients. Conversely, the purely practically trained strength and conditioning specialist won’t be able to provide a rationale for specific training or nutritional programs. They are more likely to follow the fad of the week or month. Athletics are the ultimate proving ground for training methods and theories. Athletes quickly pay the price for poor preparation. Academic preparation and continuing education will help you master the theory of training and provide a rationale for exercise and nutrition recommendations. Coaching and athletic experiences put International Sports Sciences Association 8 | Unit 1.1 theories to the test. Sometimes the theories are useful, but sometimes they are impractical and essentially worthless.

Strength and conditioning coaches must know how to promote fitness for wellness (i.e., cardiorespiratory endurance, muscular strength, muscular endurance, flexibility, and body composition). Trainers should know the latest information about the influence of diet and exercise on heart disease, cancer, stroke, diabetes, and immune function. They should be well versed in training techniques that develop power, skill, coordination, speed, reaction time, and balance. These skills are largely developed through specific training—stressing the body the way you want it to change and improve. Building fitness for competition takes more time than does building fitness for wellness. The investment in time is worth the effort because of the many physical and mental rewards provided by competitive sports. At the highest levels, working with athletes preparing for the NFL, NBA, Olympics, or professional wrestling can help them earn millions of dollars and achieve life-long dreams. Economics for the Specialist in Sports Performance Enhancement: Athletes, 1ÄúÄĖ§òoĬ¶òÝ·ƕħùĝƕ§ú½I㶠Opportunities CNN rated personal trainer among the top 20 best jobs in the United States. There is solid evidence that regular exercise is essential for health and longevity. Unfortunately, more than 50% of Americans do not get the exercise they need. Medical costs have exceeded the rate of inflation for more than 50 years. This makes disease prevention and health promotion essential for the economic prosperity of countries around the world. According to industry statistics, the median pay for strength and conditioning coaches is $56,000 a year, with many trainers exceeding $100,000 a year. Job growth is expected to increase by 24% in the next 10 years. We hope that salaries will increase proportionately. Job opportunities are extremely diverse. Although many trainers Sports Performance Enhancement Essential Knowledge for the Specialist in Sports Performance Enhancement | 9 work for established health clubs and gyms, others work in health-care facilities such as hospitals; retirement facilities; specialized treatment centers (i.e., diabetes, pregnancy); high school, college, or professional teams; and physical therapy practices. This course will prepare strength and conditioning specialists to work with tactical athletes such as military personnel, firefighters, and police officers. Many strength and conditioning specialists maintain private practices. They often work with high-level athletes but more often specialize in high school or college athletes. Recruiting Clients: Most strength and conditioning coaches work with adults who have money and discipline and generally are motivated to exercise. Adults want to look physically attractive, thin, fit, and healthy. The competition for competitive athletes is often fierce, which is why you need both academic knowledge and practical experience. The market is large and, to some extent, untapped. The strength and conditioning coaches can help people improve health and fitness, and they can make athletes more competitive and develop training skills that will help them succeed in sports. Most strength and conditioning coaches obtain clients through health clubs, word of mouth, or their private office or home practice. Working with athletes is not much different. Athletes typically participate on club and school teams, so these are good places on which to focus your recruiting efforts. Your best bet is to attain the endorsement or at least passive cooperation of the coach. People can also become aware of your services through blogs, Internet sites, newspaper advertising, after-school activities, social media, bulletin boards, and brochures. Brochure: A good brochure is vital to any strength and conditioning coach. Handing out a well-produced brochure enhances your image as a professional and will help attract customers willing to spend money for a quality trainer. Your brochure should include your photograph, target population, list of services, schooling, certifications, and experience (athletic and personal training). Be upbeat and emphasize your strong points. If you have only a high school diploma but are a champion bodybuilder or fitness competitor, emphasize your athletic experience and certifications. Push your credentials to the max if you have a master’s degree in exercise physiology or related fields. Create your brochure or website with a professional flair. Explain your services simply and concisely. Have a rate (cost) sheet available, but do not publish it in the brochure. Distribute the brochure in places frequented by athletes or their parents—sporting goods stores, health clubs, gyms, school bulletin boards, and online. Relationship with Parents: If you work with young athletes, parents are the best link to new clients. Obviously, parents pay the bills, so you will not get far without them. In addition, parents often have higher ambitions for their children than the children do themselves. The bottom line: get parents on your side. You are the professional, so you need to draw the line at parents’ telling you how to do your job. This requires tact and finesse. Overzealous or overprotective parents can negatively affect a child’s progress, self-image, and motivation for International Sports Sciences Association 10 | Unit 1.1 training. The strength and conditioning coach must walk a fine line between soliciting parental support and maintaining independence. Relationship with Schools and Sports Clubs: Schools are an excellent source of clients. Many school athletic programs use part-time coaches and lack continuity from one year to the next or even one season to the next. The strength and conditioning coach can help athletes develop fitness systematically over a long period. Strength and conditioning coaches can also be seen as a threat to the school program. Jealousy from the coach, other athletes, or parents can cause problems. The trainer must walk a fine line between doing what is best for the child and getting along with the school administration. You must not ignore the coach’s or school administration’s wishes. At the same time, you probably know training techniques of which they are unaware. If you do not maintain good cooperation with the school, try to coordinate your training program with the school timetable to avoid overtraining the athlete or interfering with his or her sports skill development. Club Sports: Club sports are common in most parts of the world—particularly in Europe and South America. Poor sports programs in many American schools have prompted the development of well-funded club sports programs particularly in soccer, gymnastics, figure skating, volleyball, tennis, baseball, swimming, water polo, and long-distance running. Sports clubs are a great source of clients. Some trainers develop formal relationships with clubs—even to the extent of becoming the club’s strength and conditioning coach. As is the case with schools, be aware of the club coach’s “turf” concerns. Sports Performance Enhancement Schools: Schools often restrict their facilities, particularly during school hours. Be aware of local regulations when using school facilities for training. Never decide just to use a facility because it is there! Volunteering as a part-time coach will often allow you access to school facilities and offer you some legal protection. Health Clubs: Gyms have built-in clientele— athletes would not be there if they or their parents were uninterested in fitness and sports. Some gyms allow outside trainers to use their facilities, whereas others will not. Try to establish a formal relationship with several clubs in town. Even if you have to share revenue, maintaining a good relationship with the best clubs in town will pay dividends to you in the end. Working with unique populations: People with special needs—physically or mentally disabled, asthmatics, diabetics, or the overweight and obese—remain a potentially lucrative income source. Many trainers specialize and center their business on special populations. If you choose this route, learn as much about the disability as possible from up-to-date textbooks and sources of reliable information online. Examples include the American Diabetes Association (http://diabetes.org), American Lung Association (www.lung.org/lung-disease/asthma/), American Heart Association (www.heart. org/HEARTORG/), Obesity Society (www. obesity.org), and the United States Department of Agriculture (www.usda.gov/wps/portal/ usda/usdahome). You need special knowledge about how exercise, growth, and development affect the specific disability. Sports for athletes with disabilities are extremely advanced and involve truly elite athletes. This can be a good Essential Knowledge for the Specialist in Sports Performance Enhancement | 11 opportunity for strength and conditioning specialists. Working with Clients: You will make the most progress with clients and establish a thriving business if you have a plan. This plan includes legal and ethical considerations, a preliminary questionnaire and history, the establishment of goals and objectives, a pre-training fitness measurement, the training plan, and reevaluation. Legal and Ethical Considerations Strength and conditioning coaches are not licensed, so few standards of practice exist. In the event of legal problems, however, a judge will expect you to behave at a level consistent with that of other professionals. Working with young athletes poses legal risks not present when working with adults. Physically or sexually abusive clients, or even the hint of such, can have serious legal consequences. Behave Ethically: You must protect yourself— being unjustly accused of impropriety is little better than actually doing something wrong. The benefit of the doubt will go to the athlete. You can minimize problems by always maintaining a professional demeanor, not becoming overly friendly with clients—particularly of the opposite gender—and documenting training sessions, evaluations, and training programs. Keep a detailed daily log and always record the date and time of workout sessions along with any notes germane to the workout session such as injuries, complaints, progress. Psychologists describe the phenomenon of transference between coaches and athletes as physical attraction developed by working closely with each other. Fit young people can look like adults and appear physically attractive. The strength and conditioning coach should remember that young athletes are typically immature and easily swayed by the attention received from the strength and conditioning specialist or coach. Be a professional and do not become involved with your clients—ever. Even a false accusation can ruin your life and end your career. Drug use by athletes represents another ethical issue. You do not want to be accused of advising athletes to use illegal drugs such as anabolic steroids or growth hormone. Nearly 5% of high school athletes have used steroids, and use among college and professional athletes is invariably higher than that, so it is inevitable that you will work with people who use these drugs. Discourage drug use in your clients (https://www.dea.gov). Encourage athletes to develop strength, speed, and power naturally without the aid of illegal drugs. It is acceptable to educate athletes about the risks and benefits of these drugs, but the strength and conditioning specialist should never be perceived as advocating their use. Insurance: Most professional organizations offer professional liability and malpractice insurance to their members. These policies are usually reasonable and well worth the money. Defending even a groundless lawsuit can be financially draining. It would be prudent to consult with a lawyer about which type of insurance and coverage to purchase. Written Questionnaire: The history and goals questionnaire is essential to assessing International Sports Sciences Association 12 | Unit 1.1 your client, prescribing the exercise program, and determining the nature and intensity of training. Begin with a thorough medical history, including past illnesses, surgeries, and medications. The questionnaire should include background about the parents, including health and athletic history. Obtain a detailed account of athletic and fitness experiences including health clubs, school sports, club sports (e.g., Little League baseball), professional sports, and sports camps. Record a physical description of the client that includes height, weight, and age. Ask for a list of short-term and long-term goals. ÄĖĦÝŌ·§ĦÝăú Congratulations! You have chosen a specialized certification within the many offered by ISSA. This demonstrates your professionalism, your dedication to the field, and your desire to improve your skills. ISSA is the industry-leading first fitness organization in the United States to be accredited by a federally recognized agency (Distance Education Accrediting Commission, DEAC). The Accrediting Commission is listed by the US Department of Education as Sports Performance Enhancement a nationally recognized agency, recognized by the Council for Higher Education Accreditation (CHEA), and recognized by the International Health, Racquet & Sportsclub Association (IHRSA). ISSA is an approved full affiliate of the National Board of Fitness Examiners. Currently, strength and conditioning coaches are not licensed by any state in the United States. However, legislation has been introduced in several states requiring licensure. That said, strength and conditioning coaches are still required to act professionally as though they are licensed. Trainers must meet standards consistent with common practices followed by similar professionals. This means that certification standards by leading organizations such as ISSA become the benchmark by which personal strength and conditioning coaches are judged and held accountable. Continuing Education The fitness industry and concepts of physical training and exercise science change rapidly. Even the most thoroughly trained person forgets basic concepts over time. ISSA, and certifying agencies in nearly all fields (e.g., medicine, law, veterinary medicine, real estate), Essential Knowledge for the Specialist in Sports Performance Enhancement | 13 require continuing education. This is essential for maintaining relevancy in the field. Summary The strength and conditioning specialist must have the scientific and practical knowledge to help people improve fitness and achieve the level of performance they seek. This process involves determining the client’s goals, identifying the sport’s requirements, assessing fitness and physical capacity, and designing a program to help people achieve their goals. The combination of a general education; training in basic sciences (anatomy, physiology, chemistry, and physics); and a theoretical and practical knowledge of exercise physiology, biomechanics, nutrition, pharmacology, pathophysiology, sport psychology, motor learning, and motor development provides invaluable insight and understanding for long-term development of clients. Trainers must understand basic principles of fitness such as overload, specificity, whole-body functional training, individual differences, reversibility, periodization, rest, over-training, and stimulus variability. They should know how to achieve training effects quickly, efficiently, and without injury. Strength and conditioning coaches should have well-developed movement skills. It is impossible to teach the nuances of Olympic lifts, power lifts, plyometrics, kettlebell exercises, functional training, and bodybuilding if you cannot perform the exercises. Learning these exercises takes many hours of practice. The blend of theory and practice is essential for any trainer. The strength and conditioning specialist who is all theory will not have the practical experience required to influence athletes and clients. Conversely, the purely practically trained will not be able to provide a rationale for specific training or nutritional programs. Opportunities for strength and conditioning coach are increasing rapidly and chances for employment are expected to increase by 24% in the next decade. Job opportunities are extremely diverse. Although many trainers work for established health clubs and gyms, others work in health-care facilities such as hospitals, retirement facilities, specialized treatment centers (i.e., diabetes, pregnancy) and with high school, college, or professional teams, and physical therapy practices. Many strength and conditioning specialists have private practices. They often work with high-level athletes but more often specialize in high school or college athletes. Trainers should strictly observe legal and ethical standards. Even the appearance of impropriety can have serious professional and personal consequences. Good practice—whether self-employed or working for a company—includes maintaining accurate records, following standard practice protocols, carrying liability insurance, and maintaining relevancy in the field. No state in the United States requires licensure of personal trainers or strength and conditioning coaches. However, you should follow expected and normal practices as outlined in your ISSA International Sports Sciences Association SECTION TWO oÙŁĝÝ·§òĖ§ÝúÝúÓ UNIT 2.1 Principles of Physical Fitness 16 | Unit 2.1 Unit Outline 1. f.

Sports Performance Enhancement Principles of Physical Fitness | 17 Building Strength and Power: Crucial Knowledge for the Specialist in Performance Enhancement Strength coaches must know the theory and practice of building strength, power, and muscle mass. This requires a great deal more knowledge than simply stringing together exercises for cookie-cutter training programs. The best coaches assess athletes’ specific needs and prescribe appropriate programs. A bodybuilding program is terrific for competitive bodybuilders and for improving physical appearance but inappropriate for a football or soccer player, golfer, swimmer, or discus thrower. Except in the case of bodybuilders and people interested in general fitness, the strength coach’s goal should be to improve strength, power, and speed in highly specific motor skills. Performance in motor skills such as hitting a baseball or golf ball, blocking in football, throwing the hammer, or slalom skiing requires precise motor patterns developed by thousands of hours of practice. The conditioning program should support motor performance, not substitute it. Bench pressing 225 pounds 50 times or running a 40-yard dash in 4.5 seconds is no substitute for biomechanically precise technique. Some exercise training programs try to build power fitness by including every exercise under the sun. The best way to improve power for sports is to improve skill. Then—and only then—should you add intense conditioning. Strength and power exercise help skilled more than unskilled athletes. Building high levels of power, strength, and speed is essential for reaching the highest levels of sport, but they should never serve as a substitute for skill. This field is plagued by misinformation, zealotry, and ignorance. Forget macho exercise programs, and train smart. More is not necessarily better. Popular programs involving random high-volume high-stress exercises interfere with motor performance. Athletes cannot perform precise motor skills if they hurt so badly that they have trouble walking and can’t practice. Train for the long haul. Strength coaches should not cause muscle and joint injuries. The performance enhancement program should complement the athlete’s training program. Programs that trigger shoulder rotator cuff or back injuries hinder or destroy progress and have lifelong consequences. Athletes will be old much longer than they will be young! Research shows that stronger athletes run faster, jump higher, and throw farther. The effective performance enhancement coach has an effective knowledge of applying effective training methods and exercises that build high levels of strength and power without interfering with motor skill development. ÄŌúÝúÓ0ÝĦúÄĝĝ Few performance enhancement specialists have the luxury of working exclusively with elite athletes. A good knowledge of physical fitness and physical training for health is essential to the average trainer’s economic survival.

Distance runners and cyclists need endurance to exercise and power to move quickly. Gymnasts, figure skaters, hammer throwers, and quarterbacks must have the fitness to repetitively execute complex motor tasks.

Physical activity is just as important as physical fitness is to promote health. Physical activity promotes metabolic fitness, which benefits the body in its day-to-day functioning. For more than 50 years, fitness has been defined as aerobic capacity. Developing aerobic capacity has been the primary goal of fitness training since 1965 when Kenneth Cooper published his landmark book Aerobics. This book, based on numerous studies conducted since the early 1900s, defined fitness as the body’s ability to transport and use oxygen. Aerobic capacity is also known as cardiorespiratory capacity. The quest for aerobic fitness led to popular exercise crazes such as jogging beginning in the 1970s and aerobics classes beginning in the 1980s. Aerobic capacity, however, is only one dimension of fitness. Though important, it is not the only fitness factor necessary to develop an athlete’s peak performance. Fitness experts realize that fitness means more than a healthy heart. In addition to aerobic capacity, other components of fitness are vital to health and performance. These include muscular strength and power, muscular endurance, flexibility, and body composition. Power sports such as football, basketball, baseball, golf, tennis, throwing, sprinting, and volleyball each have special fitness requirements that go well beyond the body’s need for oxygen and wellness promotion. Principles of Physical Fitness | 19 ÄĖă¶Ý·ăĖ§Ė½ÝăĖÄĝēÝĖ§ĦăĖŁ§ē§·ÝĦŁ Supplying energy for activities lasting more than 30 seconds depends on the consumption and use of oxygen (O2). Most physical activities in daily life and athletics take more than 90 seconds, so O2 consumption is critical for survival including performance. Oxygen consumption increases as we progress from rest to easy exercise to intense exercise. The maximum rate that people consume O2, called • maximal oxygen consumption or VO2max (a scientific symbol meaning the volume of oxygen consumed per minute), is one of the most important factors determining how hard they can exercise, how long they can sustain exercise, and how quickly they recover.

Cellular endurance capacity refers to how cells consume oxygen, process fuels, and transform energy for cell functions such as muscular work. Cellular endurance capacity is an extremely important part of aerobic capacity because the cells ultimately supply energy for exercise. Oxygen consumption and much of the cell’s energy production occur in the mitochondria—the powerhouses of the cells. Mitochondria allow the cells to consume oxygen, use fat as fuel, and protect themselves against destructive chemicals called free radicals. Free radical damage may be a cause of aging, disease, and tissue injury. "ŀÄĖ·ÝĝÝúÓĦăÄĺÄòăēÄĖă¶Ý·§ē§·ÝĦŁ Endurance exercise best develops both components of aerobic capacity.

Section 4 of this course discusses the development of aerobic capacity and endurance in further detail. Sports Performance Enhancement "ŀÄĖ·Ýĝħú½7ħòĦÙ It is official. The surgeon general has determined that lack of exercise is hazardous to health. In 1996, the government issued the landmark “The Surgeon General’s Report on Physical Activity and Health.” It stated that regular, moderate activity dramatically reduces risk of many diseases and health problems. Prior to 1980, exercise recommendations emphasized vigorous exercise and participation in team sports such as basketball and soccer and activities individuals could pursue on their own such as jogging. The first exercise recommendations from the American College of Sports Medicine (ACSM) were issued in 1975. The ACSM recommended exercise three to five days a week for 15 to 60 minutes at 50% to 85% of heart rate reserve (maximum heart rate – resting heart rate + resting heart rate). These guidelines were modified in 1978, 1990, 1998, and 2011 to reflect current knowledge on the effects of exercise on health and body composition. During the 1980s and 1990s, research showed that moderate-intensity exercise promoted health and longevity. This led to changes in exercise recommendations from the United States Surgeon General (issued in 1996), the Department of Health and Human Services (2005 and 2008), and the American College of Sports Medicine and American Heart Association (2007 and 2011). In 2008 and 2010, the US Surgeon General issued The Surgeon General’s Vision for a Healthy and Fit Nation and the US Department of Health and Human Services made Principles of Physical Fitness | 21 specific recommendations for promoting exercise and health (https://www.cdc.gov/nccdphp/sgr/index.htm). These reports stressed the importance of regular physical activity and emphasized that some physical activity is better than none. Regular exercise may be the single most important lifestyle activity that will make people healthier and more resistant to disease. The Centers for Disease Control (CDC), the lead federal agency for protecting the health and safety of people Prevention (www.cdc. gov/), and the Office of the Surgeon General, the nation’s leading spokesperson on matters of public health (www.surgeongeneral. gov/sgoffice.htm), stated that regular exercise is perhaps the single most important lifestyle practice people can undertake to enhance wellness. The following summarizes six ways that regular exercise can enhance overall health status: 1.
