Differences in Repetitive Strength and Strength of Kicking a Ball between Soccer Players U14 and Children who are not Involved in Soccer

Abstract

The research is conducted with the aim of setting out the diff erences in repetitive strength of legs, torso, hands and shoulder girdle and strength of kicking a ball between soccer players U14 and children who are not involved in soccer. The sample consists of two groups of respondents. The fi rst subsample group was comprised of 20 respondents of chronological age between 12.50±0.43 who were actively involved in training process at soccer team Stars, and the other subsample included 20 respodents of chronological age between 12.50±0.62 involved in system of Physical Education but who were not involved in training process of other sport branches. Canonical Discriminant Analysis within set of four motoric variables is used to determine the basic diff erence between groups and the contribution of each variable taken individually in overall discrimination groups. The sample of respondents who train soccer achieved better results in all applied tests. All tests showed statistical signifi cance in discrimination of groups other than the test for assessing the strength of kicking a ball which is at the very margin of significance.
