  15. Role of Carbohydrates in Sport • The body’s main source of fuel. • - They are used in a various range of sports. • - The carbohydrate intake should be specific to the chosen sport.

  16. Role of Carbohydrates in Sport • There are certain considerations to incorporate when developing a diet plan. • Specificity within the chosen sport.

  17. Role of Carbohydrates in Sport ? • Carbohydrate loading • Blood Glucose loading • Glycaemic Index • Daily Intake • Pre Competition nutrition • Post Competition nutrition ? ? ? ? ? ?

  18. Rebound Hyperglycemia • Rapid increase and then rapid decrease of the body’s sugar levels • Caused by the over consumption of high GI carbs 15-45 minutes before exercise. • Results in less fuel available for exercise. • Athlete will feel less energetic and highly fatigued.

  19. Rebound Hypoglycemia

  20. Blood Glucose Loading • Blood glucose is a main source of energy. • Used in the Lactate and Aerobic systems • Regulates the amount of Glucose released from the liver • Transported to muscles through the blood stream.

  21. Blood Glucose Loading • Glycogen is stored in the liver and muscles. • Liver breaks down stored glycogen. • If the liver cannot meet the body’s demand, will take from muscle stores.

  22. Blood Glucose Loading • Day of Competition • Pre-event meals should- • Top up glycogen and glucose stores. • Top up fluids. • Participant should feel satisfied.

  23. Carbohydrate Loading What is it? CHO loading is diet manipulation aimed at increasing the muscle cells glycogen stores.

  24. Carbohydrate Loading Two Protocols General Taper exercise by 50% in the last week before the event. Then by another 50% 3 days before the event Over this period the athlete should consume 8-10g of CHO per kilo of body weight.

  25. Carbohydrate Loading Two Protocols Strict Day 1, Exhaustive exercise. Day 2, 3, 4, Moderate intensity training and low CHO intake 9 ( 100g per day). Day 5, 6, 7, Athlete will consume 400g-700g per day to CHO load.
