Nutrition in sport
1987
Some dietary practices of athletes in pursuit of success are sound; others have no scientific foundation and may even be harmful. Data for most athletes suggest that they are in energy balance within the limits of the techniques used, but data for women engaged in sports for which a low body-weight, and especially a low body fat content are important, consistently show a lower-than-expected energy intake. Athletes engaged in strength and power events have traditionally striven to achieve a high protein intake. However, the energy requirements of training are largely met by oxidation of fat and carbohydrate; the primary need is for enough carbohydrate to enable the training load to be sustained at a high level. Water uptake is greatest from dilute glucose-electrolyte solutions, although optimum strategy for replacement depends upon the nature of the event, environmental conditions, and the individual.(rah)
