Journal Title: Antropomotoryka. Journal of Kinesiology and Exercise Sciences - Year 2003, Vol 13, Issue 26
Abstract
Tetrathlon, the four-even field and track competition, is commonly treated as a basic form of creation of the general motor fitness of children, which determine their future sports achievements. In events this competition consists on - 60 m run, long jump, small ball (baseball) throw and 1000 m run - a special role plays the muscle strength in relation to the somatic build of a competitor. In the presented paper the methods of evaluation of an actual strength fitness of weightlifters were compared with the traditional forms of the relative strength determination. The obtained results confirm conclusions the author came in his previous papers, namely the advantage of the new indices in evaluation of the relative muscle strength in comparison with previous methods as well as the necessity to apply these indices only to groups of children which are uniform in age and are characterized by small dispersion of their physical fitness.
