目的：探讨8周预负荷练习与非预负荷练习对肌肉力量的影响。方法：以浙江省16名女子乒乓球队员为实验对象,利用Isomed 2000等速测力系统和Mega 6000肌电系统分别对左、右两侧的肘关节肌力和肌电信号进行同步测试。结果：1）与非预负荷组相比,预负荷组的相对峰力矩和平均IEMG增长均显著性提高（P〈0.05）;2）预负荷组的力矩加速能具有显著性提高（P〈0.05）,非预负荷组则没有显著性变化（P〉0.05）;3）预负荷组和非预负荷组肱二头肌围度无显著性差异（P〉0.05）。结论：预负荷练习能够有效地提高肌肉最大力量、爆发力和肌肉围度。预负荷练习比非预负荷练习能够有效的提高肌肉最大力量和爆发力,而对于肌肉围度没有差异。

Objective： The purpose of this study was to explore the effect of 8-week preloading training and non-preloading training on muscle strength. Methods： Sixteen female table tennis players from Zhejiang province team were recruited in this study,and the strength and s EMG of elbow muscles were tested by Isomed2000 isokinetic testing system and Mega 6000 SEMG test system. Results： 1） Compared with non-preloading training group,the relative peak torque and average IEMG in preloading training group are significantly higher（ P〈0. 05）. 2） The acceleration energy of torque has been improved in preloading training group（ P〈0. 05）,but not in non-preloading training group（ P〉0. 05）. 3） There is no significant difference of biceps brachii＇s circumference between the two groups（ P〉0. 05）. Conclusions： Preloading training can improve muscle＇s maximum strength,muscle＇s explosive force and muscle＇s circumference. Its effects on muscle＇s maximum strength and muscle＇s explosive force are more effectively than non-preloading training＇s,but it has the same effect on muscle＇s circumference as nonpreloading training.
