Abstract | |
This work of has several arms: first, to describe in kinanthropometrics terms top level male volleyball athletes at São Paulo State in different competitive categories - from minor to major and verify the existence of relationships among morphological aspects and motor performances; second, to verify the behavior of kinanthropometrics variables among athletes belonging to different competitive categories. The goal here is trying to determine how variables should be ranked in importance to define performance and how this ranking changes as we go from one stage to the next one; third, to compare four possibilities of procedures that may be used on the athletes ranking in different competitive stages namely: a) coachs subjective classification; b) classification using the standard Z score; c) classification using the coefficient derived by means; d) classification using the analysis of principal components. One tries to point out the ones which more effectively may cooperate in the process of selection and promotion of talent to volleyball. In order to make the comparison, a sample of 75 male volleyball athletes between the ages of 13 and 28 years old, divided among all the different competitive categories were evaluated in kinanthropometric terms by using the variables considered important to the practice of high level volleyball. It was possible to conclude that, 1) the evaluated athletes presented kinanthropometrics values close and/or superior to the expected for high competitive level male volleyball athletes in the variables measured, showing the good level of the athletes involved in the study; 2) there are differences in the importance of the variables in the passage from a lower stage to the following next ; 3) the coefficient of classification by means in this study seems to indicate that the multivariate analysis is more adequate to give better understanding of the complexity that involves the process of talent promotion (AU) |
