确定影响运动成绩的关键因素，对于发展运动员的技术和力量具有重要意义。许多武术形式已被研究，但一个相对较新的武术比赛形式，散手，还没有被分析。本研究的目的是确定在发展的三手运动员，特别是女性参与者的关键属性。6名精英选手和6名新手选手使用等速测力计以60度/秒和180度/秒两种速度连续重复30次躯干段、膝关节和肘关节的周期性伸展和屈曲。关注的变量为最大扭矩产生、标准化扭矩（Nm/kg）、疲劳指数（前三个循环中三个最大力的平均值/后三个循环中最大力的平均值）和扭矩发展速率（Nm/s）。结果表明，两组之间的显着差异，只有在躯干屈曲的最大扭矩，标准化扭矩，和力的发展速度，而运动速度之间的差异是明显的多个变量在每个解剖区域。这些分析有助于提供进一步的信息，可能的关键因素，在发展中的散手女运动员。进一步的工作需要确定更多的参数在发展三手运动员。中国运动生理学与体适能学会版权所有（C）2013由爱思唯尔（新加坡）私人有限公司出版。版权所有。
Determining the key factors in athletic performance is important for developing the technique and strength of athletes. Many martial arts forms have been studied, but a relatively new form of martial arts competition, San Shou, has not been analyzed. The purpose of this study was to determine key attributes necessary in the development of the San Shou athlete, particularly in female participants. Six elite and six novice competitors performed 30 continuous repetitions of cyclic extension and flexion of the trunk segment, knee joints, and elbows joints at two velocities, 60 degrees/second and 180 degrees/second, using an isokinetic dynamometer. Variables of interest were maximum torque production, normalized torque (Nm/kg), fatigue indexes (average of three maximal forces in the first three cycles/average of maximal forces in the last three cycles), and rate of torque development (Nm/s). Results indicate significant differences between groups only during trunk flexion for maximum torque, normalized torque, and rate of force development, whereas differences between movement velocities were apparent for multiple variables at each anatomic region. These analyses assist in providing further information regarding the possible key factors in developing the San Shou female athlete. Further work is required to identify additional parameters in developing the San Shou athlete. Copyright (C) 2013, The Society of Chinese Scholars on Exercise Physiology and Fitness.
