三种深蹲动作模式肌电特征的研究

目的：对3种不同深蹲模式进行肌电测试，以期探讨不同模式下动作的合理性，为教学、训练提供一定的理论依据。方法：本文运用文献资料法、实验法和数理统计法对不同模式的肌电测试进行对比分析研究。结果：动作模式1与动作模式2相比，股内侧肌、股直肌、股外侧肌、臀大肌有非常显著性差异（P〈0.01），股二头肌有显著性差异（P〈0.05）。动作模式1与动作模式3相比，股内侧肌、股直肌、股外侧肌、臀大肌有非常显著性差异（P〈0.01），股二头肌有显著性差异（P〈0.05）。动作模式2与动作模式3相比，股内侧肌、臀大肌有非常显著性差异（P〈0.01），股直肌、股外侧肌有显著性差异（P〈0.05），股二头肌没有显著性差异（P〉0.05）。结论：3种不同模式深蹲动作的股外侧肌、股直肌、股内侧肌、股二头肌、臀大肌的积分肌电数值表现出显著性差异，动作模式3优于其它两种动作模式。在深蹲训练中强调臀部肌肉的主动收缩，才能更好的提高下肢力量的作用。

Electromyography Characteristics of the Three Squats Action Modes

Objective：EMG tests on three different squat modes to explore the rationality of action in different modes, to provide a theoretical basis for teaching and training. Methods：In this paper, use documents, experiments and mathematical statistics EMG test comparison of different modes to analysis. Results： The first operation mode and second operation mode compared to the vastus medialis, rectus femoris, vastus lateralis, gluteus maximus very significant difference （P〈0.01）, biceps femoris significant difference （P〈0.05）. The first operation mode and third operation mode compared to the vastus medialis, rectus femoris, vastus lateralis, gluteus maximus very significant difference （P〈0.01）, biceps femoris significant difference （P〈0.05）. The second operation mode and third operation mode compared to the vastus medialis, gluteus maximus very significant difference （P〈0.01）, rectus femoris, vastus lateralis significant difference （P〈0.05）, biceps femoris no significant difference （P〉 0.05）. Conclusion： Three different modes of squat vastus lateralis, vastus medialis, biceps femoris, gluteus maximus integrated EMG values showed significant differences, the third operation mode is better than the other two operation modes. Squat stressed that the hip active contraction of the muscles in order to enhance the role of the lower extremity strength.
