Carbohydrates for Performance - Following training and competition an athlete's glycogen stores are depleted. In order to replenish them the athlete needs to consider the speed at which carbohydrate is converted into blood glucose and transported to the muscles. The rapid replenishment of glycogen stores is important for the track athlete who has a number of races in a meeting.
The rise in blood glucose levels is indicated by a food's Glycaemic Index (GI) and the faster and higher the blood glucose rises the higher the GI. Studies have shown that consuming high GI carbohydrates (approximately 1grm per kg body) within 2 hours after exercise speeds up the replenishment of glycogen stores and therefore speeds up recovery time. There are times when it is beneficial to consume lower GI carbohydrates which are absorbed slowly over a longer period of time (2-4 hours before exercise). Eating 5-6 meals or snacks a day will help maximise glycogen stores and energy levels, minimise fat storage and stabilise blood glucose and insulin levels.

Eating and Competition - What you eat on a day-to-day basis is extremely important for training. Your diet will affect how fast and how well you progress, and how soon you reach competitive standard. These pages provide some general nutritional advice to help you manage your weight and body fat.
Once you are ready to compete, you will have a new concern: your competition diet. Is it important? What should you eat before your competition? When is the best time to eat? How much should you eat? Should you be eating during the event? And what can you eat between heats or matches? A lot of research has been done in this area, and it is clear that certain dietary approaches can enhance competition performance.
