摘要:	目的：本研究以站立於震動機臺上練習太極拳的方式，探討太極拳結合震動訓練對膝伸肌最大等長肌力、等速肌力、肌電活化、電機械延遲與發力率等影響。方法：48位一般大學生分爲3組：太極震動組、太極拳組以及控制組，進行爲期8週、每週3次的訓練。訓練前後以Biodex等速肌力儀、Biopac多功能訊號擷取系統與表面肌電片，測試膝伸肌之最大等長肌力、等速肌力與肌電活化。統計分析以混合設計二因子變異數分析來進行考驗，顯著水準定爲α=.05。結果：太極震動組的60°/s等速向心肌力顯著進步11.8%。此外，太極震動組在各等速收縮時的肌電活化程度降低，但其肌力卻呈現增加的趨勢；太極拳組及控制組在各依變項中均無顯著變化。結論：在8週的訓練中，太極拳結合震動訓練可有效增進膝伸肌等速肌力的表現。 Purpose: The study was to investigate the effects of Tai Chi combined with vibration stimulation on maximal isometric contraction, isokinetic contraction, muscule activity, electromechanical delay and rate of force development by playing Tai Chi on the vibration training machine. Methods: Forty-eight normal university students were recruited as subjects and randomly assigned to three groups: Tai-Chi-Vibration group, Tai chi group and control group. They were participated training programs for eight weeks, three times a week. Before and after the training, maximal isometric contraction, isokinetic contraction and muscule activity of the knee extensor were measured by Biodex dynamometer, Biopac multi-function signal recorder and bipolar surface electrodes. The collecte data were analyzes by mixed design two-way ANOVA. The level of significance was set at α=.05. Results: 60°/s isokinetic concentric contraction of Tai-Chi-Vibration group was significantly improved 11.8%. In addition, muscule activity of Tai-Chi-Vibration group in each isokinetic contraction was decreased, but the torque showed a increased trend; There were no significant results in Tai chi group and control group. Conclusion: Tai Chi combined with vibration training for eight weeks can significantly improve isokinetic contraction of knee extensor.
