Body Composition and Dietary Intake in Athletes of Different Age, Sex, Performance Capacity and Specialization
Adequate dietary intake and proper nutritional status belong to the most important determinants of physical fitness and performance: insufficent and/or too abundant intakes of energy or of other nutrients may interfere with optimal level of physical performance and ability of sport training on a necessary level. Most sport disciplines do not require special dietary allowances, and a well-balanced diet as recommended for the individuals of the normal population with enough energy ought to satisfy athlete’s dietary needs. However, just as in the subjects of the normal population, a disbalanced diet with slight deficiencies of e.g. vitamins and/or minerals is also quite frequent in athletes: prevention of such errors can help to improve athletes’ ability to undergo very high work loads during training to guarantee the satisfactory imunoresistency, emotional stability and so forth. The problem is even more urgent in growing athletes the proportion of which has been steadily increasing among champion participants in top level competitions. Moreover, in some sports low weight along with low fatness and thus decreased food intake are necessary; this enables more often a disbalanced intake of necessary items of food.
