拔罐介入對於運動疲勞和肌肉活化電訊號的影響

Effect of cupping therapy on fatigue recovery and electromyography

研究目的：為探討肌肉疲勞後進行拔罐介入對運動表現和肌肉活化程度的影響。研究方法：本篇研究收錄三位有運動習慣之大專男性，每人將接受定罐組、動罐組和控制組三個組別之介入。實驗過程使用肌電訊號接收器及一臺測力板測量疲勞前、後以及介入後30分鐘內的肌肉活化變化和彈震式伏地挺身的力量峰值。本次實驗採用描述性統計呈現拔罐介入前後運動表現、肌電活化程度和肌電中位頻率的變化趨勢。結果與結論：在受試者疲勞後使用拔罐的介入，定罐或動罐皆有立即的力量恢復效果，且在post30發現定罐組力量恢復的程度最接近前測值。發力率方面，定罐組在介入後就有立即恢復的趨勢，但動罐組post30恢復的程度最大，最接近前測的數值。肌肉活化方面，定罐組PM在post30時有回升趨勢，且回升幅度比靜態組大。雖然動罐組相較於其他兩組在post0時PM和AD的活化程度有降低趨勢，但在整體的活化程度上都較接近mid的值。因此定罐與動罐組能產生力量以及發力率回升的趨勢有可能來自於拔罐時肌肉活化提升，使更多運動單元幫助出力。後續實驗可針對肌電活化程度和運動表現之關聯性做更進一步探討，以推斷在固定的實驗方法下，拔罐介入使肌電活化程度增加的現象對於運動後疲勞的恢復是否真的具有正面的影響。

Purposes: The purpose of this research is to find out how cupping therapy takes effect on fatigue recovery and electromyography. Methods: There are 3 healthy collegiate students with exercise habit included. Each of them will receive 3 groups of intervention, including static cup, moving cup and static rest. The participant will be excluded if they have upper body injury in 6 months, wound on expected cupping area, bleeding and not accept the side effect of cupping. The electromyography and force data will be collected on these points: before the fatigue trial, right after the fatigue trial, and 10, 20, 30 minutes after the fatigue trial. The descriptive statistics is the statistics method, which describes the trend of performance and electromyographic data. Result: The recover of force output shows immediately increase on static and active cupping group, also found that the force output of post30 from static cupping group is the closest to pretest value. The post0 of static cupping group shows increasing trend of RFD, on the other hand, the post30 of active cupping group shows the highest recovering effect. The muscle activation of post30 of static cupping group shows more recovery than the post30 of static group. Although PM and AD activation level of active cupping group shows decreasing trend, but its active level is closer to the value of mid. Conclusion: The recovery of strength and RFD in active and static cupping group may due to the increased level of muscle activation, which recruit more motor unit for performing power push up. The following researcher can focus on the relationship between muscle activation level and sports performance, in order to find out whether cupping therapy works for improving recovery of sports fatigue or not.
