      • Sports Drinks
      • Intravenous Drips
    • NEED TO DO
      • Compare and contrast practices designed to enhance performance and recovery
      • Analyse and evaluate nutrition and hydration procedures to enhance individual performance and recovery
    • WHEN IS DIET IMPORTANT?
      • Pre
      • During
      • Post
    • CARBOHYDRATE LOADING
      • 10 days prior to major competition
      • Increase in carbohydrate stores
      • Tapering training
      Discuss the following:
      • Carbohydrate loading is only really of benefit for endurance events lasting longer than 90 seconds

    • Carbohydrate loading
      Sample menu plan for a 70kg athlete aiming to carbohydrate load. Note that it is important to snack regularly when carbohydrate loading.
    • GLYCEMIC INDEX
      • Scale 0 to 100
      • Effect on blood sugar levels in 2 hours
      • Pre exercise – Low GI
      • During Exercise – Moderate – High GI
      • Post Exercise – High GI
    • ACTIVITY
      HUMAN CONTINUUM
      Rank each of the following foods according to their glycemic index in a continuum from one side of the room to the other
    • HYDRATION
      • Body core temp around 37 degrees
      • How do we hydrate?
      • Is only hydration important?
