Dehydration and substrate depletion are major factors in fatigue during prolonged exercise, and carbohydrate and fluid have independent and additive effects on performance. Sports drinks supply substrate in the form of carbohydrate as well as water to replace sweat losses, and have a clear role to play during any activity where fatigue is likely to influence the outcome. This applies as much to team games, where skill generally deteriorates in the later stages of the game, as to endurance running or cycling events. The optimum type and concentration of carbohydrate and the amount of sodium will depend on various factors including the intensity and duration of exercise, the ambient environmental conditions and on the individual physiology of the athlete. The basic formulation can be varied by the addition of other components such as proteins and amino acids as well as a wide range of other ingredients. |
