摘　　要：目的:使用不同频率的振动刺激对排球运动员进行9周力量训练,分析何种频率的刺激对改善力量和平衡能力的效果更好。方法:将实验对象随机分为对照组、30 Hz组和45 Hz组,训练前后采用三维测力台测试蹬伸峰值力和相对冲量,采用平衡测试仪测试平衡能力。结果:实验组峰值力提高幅度大于对照组,45 Hz组测试数据明显优于30 Hz组;相对冲量方面,除30Hz组助跑起跳与对照组无明显差异外,实验组其余各指标与对照组比较差异明显,45 Hz组测试数据提高幅度明显优于30 Hz组;平衡能力测试中,实验组与对照组组间比较差异显著,两实验组除左脚平衡能力X轴向移动总距离外,其余各项指标45 Hz组均明显好于30 Hz组。结论:附加振动刺激能对力量和平衡能力产生有益影响,45 Hz振动刺激对于改善力量和平衡能力效果优于30 Hz。Objective ： applied vibration stimulation of different frequencies to volleyball athletes in a 9 - week strength training and analyzed which frequency is better in improving athletes＂ strength and balance ability. Methods： randomly divided subjects into control group, 30 Hz group and 45 Hz group, tested pedaling and stretching peak force through 3 dimensional dynamometer before and after the experiment, and tested balance ability through balance tester. Result： The peak force of experiment group was better than that of control group, the test data of 45 Hz group was significantly better than that of 30 Hz group ; in terms of relative impulse, there was no significant difference in running take - off between 30 Hz group and control group, all the indicators in experiment group were significantly different as compared with control group and the test data of 45 Hz group were better than 30 Hz group; in balance ability test, the difference between experiment group and control group was dramatic, 45 Hz group was better than 30 Hz group except left lower limb＇s balance ability in X - axis direction. Conclusion： The vibration stimulation has positive effect on athletes＇strength and balance ability, 45 Hz vibration stimulation is better than 30 Hz vibration stimulation in improving athletes＇strength and balance ability.
