| Summary: | 碩士 === 國立屏東教育大學 === 體育學系 === 97 === Purpose: The purpose of this study was to probe the effect of different vibration stimulation types for the elbow joint flexors’ performance. Method: Subjects are fourteen healthy university male students. Measured the elbow joint flexors torque of un dominate arms. In the pre-test before vibration stimulation and then the latter was assigned randomly different fore stimulation types that including：high frequency high amplitude(HFLA)(30Hz,50Nm),high frequency low amplitude(HFLA)(30Hz,2.5Nm),low frequency high amplitude(LFHA)(2.5Hz,50Nm),low frequency low amplitude(LFLA)(2.5Hz,2.5Nm) and the control group(non-vibration stimulation).
The duration of stimulation time is ten second. The post-test was take after vibration stimulation. The parameter contains the maximal force, rate of force development,and electromyography .The two-way AVOVA repeated measures are used to exam the variance (α=.05). Results: First, four kinds of vibration stimulations after vibration are different(P＜.05).Second, Demonstrated by way of the RMS of EMG index after stimulations, four kinds of vibration stimulations do not get the difference levels (P >.05).Third, four kinds of vibration stimulations after vibration, achieves the significant levels on RFD0.5S (P＜.05).Conclusion: The result showed that the muscle’s activate do not got the significance level by different vibration stimulation, The are positive effect to the elbow joint flexors’ performance.
