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.
Role of Carbohydrates in Sport
- There are certain considerations to
incorporate when developing a diet plan.
- Specificity within the chosen sport.
Role of Carbohydrates in Sport
- Carbohydrate loading
- Blood Glucose loading
- Glycaemic Index
- Daily Intake
- Pre Competition nutrition
- Post Competition nutrition

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.
Rebound Hypoglycemia
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.
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.
Blood Glucose Loading
Day of Competition
Pre-event meals should-- Top up glycogen and glucose stores.- Top up fluids.- Participant should feel satisfied.
Carbohydrate Loading
What is it?
CHO loading is diet manipulation aimed at increasing the muscle cells glycogen stores.
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.
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.
