Active people and athletes alike often view diet as a way to enhance health and optimise performance. Exercise and proper diet help to control body weight and reduce the risk of heart disease, hypertension, or other chronic diseases. Athletes, in particular, look for ways to improve their performance and often want to consume the most appropriate diet before, during and after competitive events.
When starches or sugars are eaten, the body changes them all to glucose, the only form of carbohydrate used directly by muscles for energy. Whether carbohydrates are in the form of starches (in vegetables and grains), sucrose (table sugar), fructose (found in fruits and juices) or lactose (milk sugar), carbohydrates are digested and ultimately changed to glucose. The body uses this glucose in the blood for energy. Most glucose is stored as glycogen in the liver and muscles. During exercise glycogen is broken down in the muscles and provides energy. Usually there is enough glycogen in muscles to provide fuel for 90-120 minutes of exercise. Most exercise and sport games do not use up glycogen stores so eating carbohydrates during the activity usually is not required. But for some athletes, eating or drinking carbohydrates during exercise helps maintain their blood glucose and energy levels.
