Estimation of condition and coordination abilities in ten-year-old children within the confines of sport training selection
Journal Title: Antropomotoryka. Journal of Kinesiology and Exercise Sciences - Year 2009, Vol 19, Issue 45
Abstract
[b]Introduction[/b]. In November 2007 management of the Youth Sport Center in Wrocław offered to two retired research workers in University of Physical Education Wrocław (dr Adam Haleczko and dr Ryszard Jezierski) to draw up several selection tests enabling to estimate motor abilities of 10 years old children in order to encourage them to do sport. The most gifted children could be included then into training in sports sections cooperating with the Youth Sport Center. Dr Jezierski get about organization matters while content-related side was in dr Haleczko hands, who cooperated additionally with of dr Leszek Korzewa, dr Ewa Misiołek and dr Urszula Włodarczyk. The research was done in two grammar schools during physical education classes in rather small groups of pupils so as not to disturb the teaching process what, however, prolonged the duration of examination. The study comprising: methods of determination of morphological age and prediction of the final body height was presented to the Youth Sport Center a month after end of research and, as a basic material, the instructions for currying out of certain motor trials together with related score tables (in T-scale). The essence of the study was, first of all, an evaluation of child’s condition and coordination abilities with relation to the age and the body build. The examination of relationships: school – parents – children was studied by other group of researchers. Taking into account that efficiency of selection process depends mainly on how its specific demands are obeyed, the description of the crucial principles of sports selection were presented on the basis of relevant literature.[b]Aim[/b]. Realization of the tasks presented by Youth Sport Center management.[b]Material and methods[/b]. The results were analyzed statistically with use of basic indices and Pearson linear correlations. The quotient index was defined in which product of scores of two condition trails (both-feet triple jump from standing position and chest 1 kg medicine ball put) was in numerator while product of three coordination trials scores (wall bar cross, passage over and under cross-bar, both-feet lateral jumps) formed denominator. Such defined index was signed as index I, while one in which products of scores were replaced by respective sums was signed as index II. The sum of results of five trials expressed in T-scale was applied as the third form of ability evaluation.[b]Results[/b]. The gathered material was presented in seven tables where values, steps of variability and relationships between measurements were included. The comparison of usefulness of three variants of summary ability evaluation methods was done on the basis of correlation analysis. Index I seemed to be the most promising, but to some extend it preferred older girls. The correction was possible with use of morphological age, what reduced the influence of somatic factor and decreased the age impact. To complete the presentation the three variants of relative strength indices were also presented. Two from among them because of elimination of the body mass influence on results may be used in comparison of strength abilities of children with different body sizes, increasing thereby the selection efficiency. Conclusion. To judge the prognostic validity of proposed methods of motor ability evaluation, and at the same time the selection efficacy, will be possible only after several years, of course if continuity of research will be kept.
