| 摘 要： | 目的:为深度探求三体势的运动机理,服务于健身和竞赛需要,为教学训练提供科学依据。方法:采用肌电测试系统对17位形意拳练习者的形意拳三体势单重桩和双重桩站桩过程中sEMG变化情况进行记录。结果:单重桩右腿承担体重的贡献率占72%,双重桩右腿贡献率占60%,三体势桩功均在40 s后就开始出现主要肌群的疲劳,有明显抖颤感。结论:验证了传统意义上的前4后6式肌肉用力分配的三体势,更多的是指双重桩,而前3后7式的肌肉用力分配为单重桩;单重桩和双重桩主要锻炼肌肉无明显差异;单双重桩贡献率最大的两块儿肌肉都是后支撑腿的股外、内侧肌;双重桩前支撑腿的股外侧肌肉负荷稍大于单重桩;单重桩后腿的贡献率占72%,双重桩后腿贡献率占60%;相同条件下单重桩对腿部的刺激深度大于双重桩,有利快速出功;双重桩两腿承重比例有利前后的稳定性。动作姿势正确的条件下,三体势桩功练习时机体产生疲劳的时间阈值为40 s。

| Abstract: | Objective: To explore the deep movement mechanism of Santishi,satisfy the needs of fitness and competition,provide science basis for training and teaching.Method: 17 Wushu players were called to do single pile and double pile of Santishi,and meanwhile the sEMG of certain muscles were recorded.Result: The right leg undertake 60% body weight when doing double pile,and 73% when doing single pile.The major muscle began to appear fatigue after 40 seconds when doing both the single and double Santishi,there is obvious tremors sense.Conclusion: The validation of the traditional weight of the 4: 6-type distribution of Santishi almost means double pile,and the first 3:7-type means single pile.The single pile and double pile exercise have almost the same effects on the muscles,namely,Vastus Lateralis and Vastus Medialis of the load-bearing leg,while Vastus lateralis of load-bearing foreleg is slightly larger than single pile load when doing double pile.The single pile has bigger incitement to the load-bearing leg than double pile in the same condition.Double pile is advantageous to keep body stability;40 seconds is the fatigue threshold of Santishi under the right conditions. |
