【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。
[Abstract]:Objective: to analyze the effects of different frequency of vibration stimulation on the strength training of volleyball players for 9 weeks.Methods: the subjects were randomly divided into control group (30 Hz) and 45 Hz group. Before and after training, the pedal peak force and relative impulse were measured with a three dimensional force measuring table, and the balance ability was tested with a balance tester.Results: the peak strength of the experimental group was significantly higher than that of the control group (45 Hz), and the relative impulse of the test group was significantly better than that of the control group, except for the run-up jump of the 30Hz group and the control group.The other indexes of the experimental group were significantly different from those of the control group. The test data of the 45Hz group was obviously better than that of the 30Hz group, and the balance ability test had a significant difference between the experimental group and the control group.The other indexes of 45 Hz group were significantly better than that of 30 Hz group except the total distance of X axis movement of left foot balance ability in the two experimental groups.Conclusion: additional vibration stimulation can have beneficial effect on strength and balance ability. The effect of 45 Hz vibration stimulation on improving strength and balance ability is better than 30 Hz.
