Carbohydrate and lipid requirements of soccer.

Soccer involves high-intensity, intermittent exercise and places a heavy demand on the body's liver and muscle glycogen reserves. Thus, carbohydrate depletion may contribute, in part, to fatigue and reduced performance during a soccer match. In addition, fatty acids derived from both adipose tissue and intramuscular triglyceride stores will be utilized. Soccer players engaged in strenuous competition and training should be encouraged to consume a diet that is relatively high in carbohydrate (at least 55% of total energy intake). Furthermore, the inclusion of carbohydrate in beverages consumed during and after a soccer match is likely to enhance performance and facilitate the recovery of liver and muscle glycogen reserves.
