摘要

Purpose: The purpose of this study was to the explosive strength and grades, and stride length, stride frequency, and legs length of the relationship among these parameters was further investigated for generating useful information for coaches and athletes while training. Method: 14 male senior high school sprint athletes were recruited in this study as subjects and their averaged age, grade, height, weight, and legs length are 17.36 ± 1.84 years old, 24.79 ± .89 seconds, 174.64 ± 5.28 centimeters, 64.93 ± 5.18 kilograms, and 94.43 ± 3.85 centimeters. As using the standing long jump which jumps three times continuously be the grade of explosive performance; then we record the athletes of 200m Sprinting of the whole distance and capture data that we record. The speed of the data is film 60 second and calculate 200m times. The collected data were analyzed by descriptive statistics and we used Pearson product moment correlation to test the relation among explosive strength, legs length, and grade, stride length, stride frequency, and legs length of 200 meters. The level of significance was α = .05. Results: 200m Sprinting Explosive strength and grade performance of the subjects are negatively related (r = -.714, p ＜ .05). the relation among legs length, and stride length are positive (r = .574, p ＜ .05). Conclusions: (1) 200m of the whole distance, athletes' lower limbs will impact their grade of performance. Shows the worse of the athlete's grade is, the worse explosive strength of the athletes will be. (2) Those tested who the lower limbs are related between the strength and stride length, so the athletes who have longer strength and so does the bigger stride length than others. As we cans say that the length of lower limbs impact on the performance of ability.
