不同運動項目選手下肢動力特性之探討

This study compared lower-limb power in different sports and provided useful information for the coaches in training. The Chinese Taipei Women Volleyball team, the Softball team and the Soccer team participated in this study. All subjects performed squat jumps (SJ), counter movement jumps (CMJ) and one-minute continuous jumps with bent legs individually with their maximal efforts on the Kistler force plate. The parameters of jump height, average mechanical power, prestretch, and lower-limb muscular endurance were analyzed by one-way ANOVA. Three findings were obtained. First, there were no significant differences among the three teams on average mechanical power. However, the height of SJ (42.58±2.76 cm) and the height of CMJ (45.62±3.3 cm) were significantly higher in the Volleyball team players than those in the other two teams (p＜.05). Second, the ability of prestretch in the Soccer team players (11.15±5.82%) was significantly better than the other players in the other two teams (p＜.05). The Softball team players were the second and volleyball team players were the third. Third, the Soccer team players (67.59%) were significantly better on muscular endurance than the Softball team players and the Volleyball team players which were in the second and third places (p＜.05). The results of this study indicated that there were some differences on lower-limb power in different sports. Coaches and athletes of different sports can understand further and clearly about the characteristics of the lower-limb power from this study. The results of this study can also provide a useful reference in sports training program in the future.
