ABSTRACT

Carbohydrates are the main source of energy during prolonged moderate-to highintensity endurance exercise and repetitive, high-intensity activities that utilize the anaerobic energy systems. Sugars and starches consumed in the diet are stored within the body mostly in the form of glycogen, which can be rapidly mobilized as a source of energy during exercise. Carbohydrate stores in the body are limited, and are not able to indefinitely sustain moderate-to high-intensity exercise. Considerable research over the last 30 years has investigated dietary carbohydrate and methods of manipulating its intake at several key time points before, during, and after exercise. This chapter will present information regarding the metabolism of carbohydrate during exercise, as well as methods for manipulating carbohydrate consumption before, during, and after training or competition with the aim of enhancing performance and recovery.
