The effect of completed nutrition on the athletes' performance

The performance capacity, some somatical parameters, the cardiorespiratory system and the anaerobic exertion of 92 athletes were studied in the function of nutrition. The traditional alimentation was completed partly by a complete food and partly by a protein-rich food. In every case in double-blind arrangements placebo was also used. The treatments lasted one month each. Between the effective and placebo treatments one months interval was kept. The complete food contained 40-60 KJ/body mass kg; the protein completion was 0.5-0.7 g protein/body mass kg. On the effect of both treatments the performance improved in more than the half of the examined persons. The increase of lean body mass could be observed mainly after protein treatment. The relative aerobic power increased significantly only after complete food treatment. The work-heart-rate did not change significantly on the effect of the treatments. The data indicate that the traditional alimentation neither qualitatively nor quantitatively can be considered optimal in more than the half of the examined athletes.
