sports drinks

commercially available drinks, designed for optimal delivery of water and carbohydrate during and after exercise. Water is often equally effective for hydration, but the taste of sports drinks makes them more likely to be taken in adequate quantities. The composition of commercial sports drinks is generally based on studies which have defined the content of carbohydrate (to supplement energy supply) and of electrolytes (mainly sodium salts) to promote fluid retention during and after prolonged exercise and to avoid hyponatraemia. There has, however, been some controversy about the standard recommendations, as some experts have disputed their adequacy in avoiding hyponatraemia, exemplified recently in studies of its occurrence in endurance athletes. Osmolality of these drinks varies according to the concentration of carbohydrate, most often in the form of glucose polymers. isotonic sports drinks contain glucose in a concentration of 6- 8% and are best for events such as middle- and long-distance running and team sports, rapidly replacing fluid lost by sweating as well as supplying an energy source. hypotonic sports drinks are suitable, for example, for jockeys, gymnasts and dancers, who need fluid but have less need for a carbohydrate top-up. hypertonic sports drinks have the most carbohydrate and are taken after exercise to supplement daily intake in the replacement of muscle glycogen stores; also used during very long-distance events when high levels of energy are required. See also hydration status.
