UNIT TITLE: Sporting champions – Born or Made? LENGTH: 5 weeks (15 hours) UNIT DESCRIPTION: This unit of work is designed to build on the knowledge and understanding students have developed surrounding physical activity and the elements which are essential in order to be a successful athlete. Students will be given opportunities to discuss and critically think about what makes a successful athlete and they will be questioned about the degree to which these areas are essential. The main focus areas are nutrition, practice, and technology. Students will discuss how these areas may or may not have an impact on whether or not an athlete is successful. Students will be presented with many real life cases where athletes have been born or made. Students will be given opportunities to debate what type of athlete they think is more successful. OUTCOMES: Knowledge, understanding and skills Evidence of learning 1.1 discusses factors that limit and enhance the capacity to move and perform 3.1 demonstrates actions and strategies that contribute to enjoyable participation and skilful performance 3.2 evaluate the characteristics of enjoyable participation and quality performance in physical activity and sport 4.3 performs movement skills with increasing proficiency A student can: Design a nutritional plan for an elite athlete Debate the use of sports drinks in enhancing performance Assess which practice method is most effective for a given movement skill Justify the role of mental rehearsal in enhancing performance Examine the role of technology in enhancing performance Discuss the strategies that are employed by elite athletes to improve performance Debate whether there is such thing as a natural sportsperson Demonstrate how mental rehearsal and practice methods can improve performance Modules: Body Systems and Energy for Physical activity (AOS 1), Nutrition and Physical Activity (AOS 1), Fundamentals of movement skill development (AOS 1), Technology, Participation and Performance (AOS 3) © PDHPE Unit 2006 Students learn about: Students learn to: Interrelationships between the body systems (AOS 1) discuss the contribution and importance of each system during physical activity (AOS 1) compare general nutritional needs for health and physical activity of specific groups (AOS 1) compare the nutrient requirements for people who engage in physical activities of varying intensity and duration (AOS 1) investigate examples of nutritional plans to assess reasons for the inclusion of particular food and nutrients (AOS 1) design a basic nutritional plan for participation in a physical activity (AOS1) describe factors that contribute to rapid fluid loss during physical activity (AOS 1) examine the consequences of dehydration and over-hydration (AOS 1) evaluate claims made by manufactures of products promoted as effective (AOS 1) participate in a variety of practice methods to assess their effectiveness (AOS 1) debate the degree to which a coach should insist on the development of conventional technique (AOS 1) justify the role of mental practice in enhancing performance (AOS 1) identify the widespread applications of technology in physical activity and sport (AOS 3) examine through research and practical participation how technology is used in a selected physical activity or sport (AOS 3) debate the degree to which technology has created equity for participants in physical activity and sport (AOS 3) Nutrition for health and physical activity (AOS 1) Nutritional planning (AOS 1) Hydration and physical activity (AOS 1) Practice (AOS 1) The contribution of technology to participation and performance (AOS 3) The ethical implications of technology (AOS 3) © PDHPE Unit 2006 Students learn about Students learn to Teaching and learning activities What is an elite athlete? Show photos of elite athletes as a discussion starter. E.g. Liz Ellis, http://www.lizellis.com.au/graphics/LizThroughHoopHawkSml.JPG: or up and coming athletes such as those on the website at www.adelaide.edu.au/eliteathletes/profiles. Ask students a variety of questions to start them thinking about what makes an elite athlete. These questions will target the areas which the unit intends to cover so that students become familiar with what elite athletes need to consider in their preparation. Sample questions: Name some elite athlete. What makes these athletes elite? What do elite athletes need to do in order to be successful? How do you know this? Does an elite athlete need to follow all of these procedures in order to be successful? Why/why not? Is it possible for an elite athlete to be born with a natural sporting ability and therefore not have to follow strict procedures in order to be successful? Why? How should elite athletes behave in public? Discuss the implications and differences in public perception around athletes who behave exemplary in public, compared to those that behave poorly? Give examples and deconstruct the role of the media in forming public perception. Use newspaper clippings and magazine articles to demonstrate this point. Ask the students to complete the self-assessment questionnaire on becoming a champion athlete. http://www.drugfreesport.com/choices/decision/assessment.html This will orientate them to the topic and see that becoming an elite athlete involves many areas of focus. © PDHPE Unit 2006 Students learn about Students learn to - Interrelationships between the body systems the reliance of body systems on each other for effective functioning, e.g. muscular system and circulatory system discuss the contribution and importance of each system during physical activity Teaching and learning activities How important is it to have all body systems working effectively to be a successful athlete? Revise the four main body systems which contribute to physical activity: skeletal, muscular, circulatory and respiratory. Discuss the muscular system and why it is important to movement. Discuss the role muscle fibres play in producing a talented athlete. Explain that there are two types of muscle fibres, slow twitch and fast twitch. Slow twitch fibres are used during endurance events and fast twitch fibres are used in sprinting events. Olympic sprinters have been shown to possess about 80% fast twitch muscle fibres while marathon runners may have 80% slow twitch muscle fibres. Which dominant fibres do you think you have? Why? With a partner Think, Pair and Share your ideas regarding whether an athlete can train to alter their muscle fibres e.g. if an athlete is born with more slow twitch muscle fibres can they train to become a sprinter? It is suggested that not enough evidence has been found to suggest that this can occur but athletes can follow the principles of conditioning in order to work towards improving their performance for a particular sport/event Identify what makes up the skeletal system through a brief discussion or quiz. Critically discuss how a broken bone would affect an elite athlete’s performance later in life? Students may suggest that broken bones are never as strong again and forms of arthritis can develop. Search for athletes who have had serious injuries and as a result have taken up a sport and become very successful and have been labelled ‘elite’. Kieren Perkins is an example of an athlete who had a serious leg injury and took up swimming as a form of rehabilitation. He then went on to become a successful long distance swimmer for Australia. Identify factors that may affect an athlete’s respiratory system. For example, the effects that asthma may have on an athlete. Discuss if having asthma stops athletes from being ‘elite’? Can participation in physical activity help a condition such as asthma? © PDHPE Unit 2006 Students learn about Students learn to Teaching and learning activities Research the percentage of athletes who have asthma or respiratory problems. Teachers can use the internet for this task or have relevant information available; for students to read through. Students need to respond to the following: 1. Identify if this has limited their chances of being successful 2. Explain how they are able to be successful yet not 100% healthy Explore how each of the systems (skeletal, muscular, circulatory, respiratory) operates during physical activity. Represent diagrammatically how each system supports the other during physical activity. Explain your diagram and how the body systems operate to another student. To support this activity, conduct an Internet search on Body systems. Some suggested web sites include: http://www.innerbody.com/htm/body.html http://www.stcms.si.edu/hbs/hbs_student.htm http://www.medtropolis.com/VBody.asp (for skeletal system) Nutrition for health and physical activity - nutritional requirements for physical activity compare general nutritional needs for health and physical activity of specific groups Does an athlete need more than the recommended nutritional requirements in order to be successful? Think, pair, and share the general nutritional requirements that are necessary everyday for any person. Collect ideas on the board, students should come up with the 5 food groups and also the serving sizes that are compare the nutrient recommended. They may even discuss the 6 essential nutrients that are requirements for people needed daily and link these to the 5 food groups in terms of where these who engage in physical essential nutrients can be found. The following table provides a sample. activities of varying intensity and duration 5 food groups and daily servings 6 essential nutrients Bread, cereals, rice and pasta – 6-11 servings Fruit – 2-4 servings Meat, poultry, fish, dry beans, eggs and nuts – 2-3 servings Vegetables – 3-5 servings Milk, yoghurt and cheese – 2-3 servings Fats, oils and sweets – sparingly © PDHPE Unit 2006 Carbohydrates Proteins Lipids Vitamins Minerals Water Students learn about Students learn to Teaching and learning activities Brainstorm the different types of athletes within society and collect the ideas on the board. These different categories can include; female, male, runners, swimmers, sprinters, endurance etc. Discuss the difference in nutritional requirements for the different categories of athlete’s e.g. female athletes ensure they have adequate amounts of iron in their diet. Choose an athlete group from the brainstorm above and outline a dietary plan for this athlete. Refer to the recommended dietary servings for each food group and examine whether these servings suit the nutritional requirements of the athlete. Allow students to discuss their chosen athlete group with a partner and critique each others nutritional plan. Nutritional planning intake before, during and after physical activity energy requirements during activity Nutritional planning factors to consider when planning healthy nutritional intake for physical activity © PDHPE Unit 2006 investigate examples of nutritional plans to assess reasons for the inclusion of particular food and nutrients Distribute a typical athlete’s diet to each student and instruct them to examine the diet using the following questions as a guide. Use this to model the next activity. Information is available at http://sportsmedicine.about.com/od/sportsnutrition/ Compare and contrast your dietary plan with this athlete? Are foods included to assist in the increase of energy levels? What foods are high in energy? Why do athletes need to time their meals? Why is this even more important when leading up to an event? What nutritional considerations need to be taken into an account after an event? Is the pre or post meal more important? Why? design a basic nutritional plan for participation in a physical activity, e.g. menu for outdoor expedition, carbohydrate loading for a fun run or triathlon To what degree is a strict diet important to an elite athlete? Students should have a basic understanding of the nutritional requirements for different athletes. This activity gives them an opportunity to research a particular athlete of interest to them. Using the internet, students research the following. What are the special dietary requirements for this athlete? This should include amount of meals per day and what foods the athlete needs to be eating to be successful When leading up to an event do the meals change? If so, how? Students learn about Students learn to Teaching and learning activities Draw up the dietary plan for this athlete. Do you think this athlete could be successful if they didn’t follow this diet? Why or why not? Suggested Internet Sites: http://www.gssiweb.com/sportssciencecenter/topic.cfm?id=61 http://www.ais.org.au/nutrition/documents/FuelNetball.pdf How important is hydration for an elite athlete? Hydrations and physical activity – role and importance of water intake during physical activity – managing fluid loss and replacement – sources of hydration describe factors that contribute to rapid fluid loss during physical activity, e.g. humidity, high temperature, alcohol examine the consequences of dehydration and overhydration analyse through case studies the fluid replacement regime of different athletes Discuss the physical effects you notice when you exercise. Collect responses on the board. Students should come up with increased breathing rate, heart rate, become thirsty and start sweating. Discuss how different environments effect these signs e.g. how high humidity makes it more difficult to regulate body temperature, how high temperatures increase core body temperature and how when swimming in a pool you don’t notice that you are actually sweating. Discuss the physical effects that would occur to an individual exercising in one of these environments. Students search the internet in order to answer the following questions. The following websites are recommended: http://www.gatorade.com.au/flash/default.asp http://chemistry.about.com/cs/5/f/blwaterintox.htm http://walking.about.com/od/fluids/ Research the following questions. Why do we sweat? What is sweat made up of? How can we replace what we lose through sweat? How important is it that you do drink fluids? What will happen if you don’t drink fluids? What happens if you drink too much? What fluid is the best to drink? Why? Refer back to the focus question “How important is hydration for an elite athlete?” Discuss the importance of effects of keeping hydrated while exercising. © PDHPE Unit 2006 Students learn about Students learn to evaluate claims made by manufactures of products promoted as effective for hydration Teaching and learning activities Research, what do sports drinks have that water doesn’t? Are sports drinks suitable for all athletes? Debate the question What athlete would be more successful, one who only drinks water or one who only drinks sports drinks? Practice - qualities of effective practice - practice methods - duration and frequency of practice - mental practice/rehearsal participate in a variety of practice methods to assess their effectiveness for developing movement skills, e.g. lay-up in basketball, abseiling descent, golf swing How important is practice for an elite athlete? Choose four students in your class who are highly proficient at a particular skill (it is ideal to have four different skills e.g. tennis serve, soccer goal kick, basketball lay up, golf swing etc). Split the class into four groups with three students to perform the skill, one highly proficient student, one student who will be given verbal instructions and the other will be given visual instructions, also a recorder in each group and a student to retrieve and set up equipment. The recorder is responsible for giving any instructions and recording the amount of successful shots by the participant. The recorder will need to be trained on what a successful attempt looks like in their skill. After all three students have completed their attempts (maximum of 10) the group then needs to graph the results to see the differences in the three students. Discuss the following questions: Who did you think would have been most successful and why? Who was most successful at the completion of the task and why? Was the highly proficient student always using the correct technique? Do you think the results would have been different if the highly proficient student was given verbal instructions to correct his/her technique? Why? The responses to these questions can be recorded in the students work books Identify a sportsperson who is highly proficient at the skill you just witnessed. Do they need to practise this skill every day? Why/why not? If they didn’t practise the skill everyday what might happen? Discussions need to surround the concept that if you don’t use it, you loose it. Discuss how if athletes stop training their fitness and skill levels drop very quickly. © PDHPE Unit 2006 Students learn about Students learn to justify the role of mental practice in enhancing performance Teaching and learning activities Imagine you are Grant Hackett (teachers can use any athlete that is appealing to their group of students); you walk out to swim the 1500m Freestyle at the World Championships in Melbourne in March 2007. What thoughts are running through your head? Record these thoughts on the board e.g. ‘I can do this’, ‘I’ve done this so many times before’, ‘I can’t let my country down’, ‘This will be a piece of cake’. Discuss what you notice about these comments. Students should notice that some are negative and some are positive. Discuss, do you think that Ian Thorpe would really have negative thoughts going through his mind? What do you think Ian Thorpe would do in his preparation to feel more positive about his ability to achieve his goals? Discussion should lead into the concept of ‘mental practice’ and how this enhances an athlete’s performance. What do you notice about elite athletes preparing for competition? Think of different groups and what they might do e.g. swimmers, footballers, netballers, track athletes, field athletes etc. Brainstorm what steps are necessary in order to mentally prepare to perform a skill successfully e.g. Be in a quiet place Relax, concentrate, and focus Take deep breaths and exhale slowly releasing any tension Once relaxed focus on the skill Tell your self that you can perform the skill successfully Visualise yourself performing the skill successfully. Groups need to go back to the original skills task and perform the skills using the concept of ‘mental practice’. Recorders need to record the amount of successful attempts out of 10 again. Discuss as a class if mentally preparing yourself this time actually made a difference. Do you think an athlete can be successful if they don’t mentally prepare? Refer back to the beginning question “Is practise really important for an elite athlete?” Discuss this question in relation to what you have learnt exploring this focus question. © PDHPE Unit 2006 Students learn about The contribution of technology to participation and performance – preparation, e.g. heart rate monitoring, technique analysis – performance, e.g. clothing, equipment, playing surfaces – judging, officiating, e.g. video replays, touch pads, wireless communication Students learn to identify the widespread applications of technology in physical activity and sport examine through research and practical participation how technology is used in a selected physical activity or sport examine through research and practical participation how technology is used in a selected physical activity or sport Teaching and learning activities Has technology made athletes more successful? Brainstorm a list of sports and the technological advances that students know or have heard of for those sports. Examples include: heart rate monitors to work out an athletes peak performance level. movement analysis is used to video and slow down performance in order to critique skill and technique. playing environments – grass compared to astro turf for hockey, diving blocks for swimming are now on an angle, sprung floors in gymnastics, indoor facilities, synthetic athletics tracks. clothing – swimmer and athletes now where tight skin uniforms. Ask the students to select a sport that they are interested in and research one technological advancement in that sport e.g. tennis and racquet technology. Explore some of the following areas. Provide students with a scaffold for their research assignment. What is the technological advancement? Does it enhance performance? Compare performances now and in previous times? What is the impact of the technology in the sport? What other technology advancements can you predict will occur in this sport? Provide a feedback sheet to the students and get them to read two other pieces of work form other students and provide written feedback one the work. You may like to provide marking guidelines to the students. © PDHPE Unit 2006 Students learn about The ethical implications of technology – comparability of performances – access and equity – illegal use of technology, e.g. drug masking – media, marketing and profit, e.g. computer games © PDHPE Unit 2006 Students learn to Teaching and learning activities Debate the degree to which technology has created equity for participants in physical activity and sport. Examples could include: - impact of drug testing - assisting referees and umpires - access to training techniques, equipment and clothing Has technology stopped naturally talented sports men and women from being the best? Set up an academic controversy with the class. Suggestions of controversial statements to be explored include: Technology has stopped the naturally talented sportsmen and women from being the best. There is no such thing as a natural sportsperson any more. Academic Controversy Instructions for academic controversy Form class into groups of two pairs (Pair A and Pair B) All groups are given the topic phrased as a statement such as – There is no such thing as a natural sportsperson anymore. Team A takes the positive position, Team B takes the negative position. Each pair has a set time (5-10 minutes) to construct an argument for their position. Team A presents their argument to Team B who listen but may not interrupt or question. Team B presents their argument to Team A who listen but may not interrupt or question. Each pair adopts the opposing position and has a set time to prepare new arguments for that position (they may not use arguments already contributed by the other pair). Team A presents as above, followed by Team B. Working together, Team A and Team B review their arguments and achieve an agreement in relation to the topic.
