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.


- There are certain considerations to

incorporate when developing a diet plan.

- Specificity within the chosen 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.


- 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.


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.


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.


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.
