Chapter 4: Diet, nutrition and the role of the energy systems Link with the Coursework Planner (PAP): Following completion of section 4.1 and 4.2 each student could analyse their own diet and hydration using a food diary, urine chart and/or app. The necessary proformas and samples are provided in the booklet.
4.1 A balanced diet Explain the main macro-nutrients including carbohydrate, fat and protein covering: • the role of each nutrient • where to find each nutrient (foods) • their importance for sport. – Ask the students to identify the most important nutrient for their sport. Explain the main micro-nutrients including vitamins and mineral covering: • the role of vitamins and minerals • their application to sport e.g. calcium for strong bones to avoid injury. NB: Students do not need to know the functions of each vitamin.
TASK 4.1 (Group work) ANSWER Research the main dietary requirements for one of the following sportspeople and report your findings to the class: –M arathon runner: High carbohydrate intake for energy; iron for RBC; calcium for strong bones; protein for recovery and repair of muscles; vitamins for energy production, immune function and blood circulation – Sprinter: Protein for muscle mass and recovery; moderate carbohydrate for energy; calcium for strong bones; vitamins for energy production, immune function and blood circulation – Jockey: Low carbohydrate and fat to maintain low body fat; protein for recovery; calcium for strong bones to avoid breaks when falling off; vitamins for healthy body function –G AA player: Carbohydrate as main energy source; protein to gain muscle mass and recovery; minerals for RBC and strong bones; vitamins for energy production, immune function and blood circulation –S umo wrestler: High fat and high protein diet to increase body mass; calcium for strong bones to carry the large mass; vitamins to maintain general health – Weightlifter: High protein diet to maximise muscle bulk, low carbohydrate and fat to avoid fat gain prior to competition, calcium for strong bones to bear the weight, vitamins for good general health.
Outline the Apply it guidelines: Nutritional considerations for performance. Discussion: Why do sportspeople need to take on additional macro-nutrients for training or competition lasting more than 90 minutes?
