Abstract

This study aimed to reveal developmental characteristics of physical fitness on the height of female wrestler of an elementary school by using a biological index from the viewpoint of growth and development. A total of 87 female wrestlers in an elementary school were assessed. Measurement items were height, weight, body fat percentage, basic physical fitness assessed by 20-m sprint, standing long jump, side steps, rebound jump (RJ) index and tackle jump peculiar to wrestling. These items, along with the height, were plotted on a logarithmic graph to obtain the allometric equation“ y = bxa”. Index“ a” of the 20-m sprint were 0.805. Index“ a” of standing long jump, side steps, and RJ were 1.492, 1.772 and 1.305 respectively. Index“ a” of tackle jump were 1.547. Considering the transition points, the standing long jump recognized transition point in about 115 cm in height. In case of side steps, RJ index and tackle jump the transition point were 115cm, 131cm and 127cm recognized in height. The basic physical fitness and wrestling ability increased with the growth in height. The main results obtained were as follows. 1. Instantaneous jumping power to forward and change of direction power follow the same developmental process. 2. Tackle continue to develop just before the adolescent peak.
