Unit 17: Nutrition for sport and exercise (LEVEL 3)

Transcription

1 Unit 17: Nutrition for sport and exercise (LEVEL 3) Learning outcomes By completing this unit candidates will develop knowledge and understanding of the role that nutrition has in sport and exercise, and nutritional and fluid requirements for different types of sports participants. Candidates will produce evidence to meet the unit assessment objectives in order to show that they understand: the relationship between nutrition and energy requirements the methods of dietary assessment the role and contribution of carbohydrate, fat, protein and micro nutrients in exercise the importance of fluid intake in exercise the value of nutritional supplements in relation to exercise. Assessment objectives 1 Describe the relationship between nutrition and the energy demands of the athlete 2 Describe the advantages and disadvantages of methods of dietary assessment 3 Analyse the roles of carbohydrate, fat and protein as fuels for exercise 4 Describe the role of micronutrients in sport and exercise performance Knowledge, understanding and skills Nutrition and energy demands: the concept of a balanced diet and recommended dietary intakes the energy value of food (kcal) energy (kcal) requirements of athletes and sedentary individuals in relation to energy balance Methods: journals/diaries recording sheets interviews software packages observation Roles: the functions, classifications and dietary sources of carbohydrate, fat and protein the role and relative contributions of each macronutrient as a fuel for exercise in relation to exercise intensity and duration feeding strategies before, during and after exercise to optimise performance Roles: exercise-related functions and dietary sources of water soluble and fat soluble vitamins exercise-related functions and dietary sources of minerals dietary requirements and rationale for increased micronutrient requirements in athletes OCR Level 3 Nationals in Sport 1

2 Assessment objectives 5 Explain the importance of fluid and electrolytes to the athlete 6 Explore and evaluate the ergogenic value of nutritional supplements Knowledge, understanding and skills Importance: implications of dehydration on sport performance and health influence of beverage composition on gastric emptying fluid intake strategies before, during and after exercise to optimise performance Issues: ergogenic properties of nutritional supplementation practices including creatine, protein powders, herbal remedies, carbohydrate loading and caffeine intake limitations of nutritional supplementation practices moral and ethical issues surrounding the use of nutritional supplements Assessment This unit is centre assessed and externally moderated. In order to achieve this unit candidates must produce a portfolio of evidence showing that they have met all of the assessment objectives. Portfolios of work must be produced independently. They will need to be made available, together with witness statements and any other supporting documentation, to the OCR Visiting Moderator when required. Centres must confirm to OCR that the evidence produced by candidates is authentic. An OCR Centre Authentication Form is provided in the Centre Handbook and includes a declaration for assessors to sign. It is a requirement of the QCA Common Criteria for all Qualifications that proof of authentication is received. Guidance on assessment and evidence requirements This unit aims to develop the candidates knowledge and understanding of the role that nutrition plays in sport and exercise. This unit has links with Unit 7: Anatomy and physiology for sport and exercise, Unit 16: Analyse and improve performance and Unit 18: Optimising performance in sport. In exploring dietary assessment methods there are a number of appropriate software packages available commercially and on the Internet. Tutors are advised to make full use of these in order to explore important concepts and principles addressed in this unit, specifically those dealt with in Assessment Objectives 1 and 2. To help candidates gain the necessary knowledge for Assessment Objectives 3 and 4 tutors should reinforce classroom-based delivery with practical assessments that allow the student to explore calorific value of foodstuffs and energy expenditure during exercise. The use of real life or tutor-devised written case studies will help candidates to examine the importance of fluid and electrolyte balance and make recommendations on the use of ergogenic aids for the training athlete (Assessment Objectives 5 and 6). Candidates may provide portfolio evidence for the assessment objectives of this unit using a range of presentation techniques. This may include written work, the use of video, audio tapes, presentations and assessor testimony/witness statements (if appropriate). Where candidates demonstrate competence, centres should record skills demonstrated on appropriate recording documentation. 2 OCR Level 3 Nationals in Sport
