The assessement of somatotype and bone mass density in female athletes

The recognition of motor abilities structure, especially the selection of measurement procedures include the most important aspects in the training process. The aim of the research was to determine the level of chosen motor abilities of 13 year old soccer players in comparison to boys of the same age not participating in any kind of sport. In this investigation an attempt was made to estimate the effects of primary selection and the first stage of soccer training. The subjects include 40 randomly chosen soccer players born in 1989 – the finalists of the U-14 Polish Soccer Championships. The comparative group consisted of 40 boys born in 1989, which were not active in any kind of sport and were somatically similar to the soccer players. The level of the following motor abilities was estimated: maximal absolute static strength, maximal anaerobic power, speed, reaction time, frequency of movements, senso-motor differentiation, static balance and space orientation. Moreover the morphological age of the examined was estimated. There were no statistically significant differences in morphological age of both examined groups. The soccer players possessed higher level of motor abilities than comparative group. The highest differences in the results of both groups were noticed in the tests evaluating the following motor abilities: frequency of movements, speed and the maximal anaerobic power. Greater differences were observed in the area of conditioning than in coordination.
