拔罐介入對於運動疲勞和肌肉活化電訊號的影響

Abstract

目的：此篇研究的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。方法：本篇研究收錄10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。受試者半年內若有上肢損傷、拔罐區域有傷口、出血以及無法接受拔罐的副作用等等，皆予以排除。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。統計方法選用單因子變異數重複量數分析，呈現運動表現和肌電之活化程度及中位頻率之變化趨勢與差異。結果：在受試者疲勞後使用拔罐的介入，無論是定罐或動罐組在不同時間點，統計上皆未發現顯著差異。不過趨勢上看似有立即的力量恢復效果，並且在post30發現定罐組力量恢復的程度最接近前測值。發力率方面，則是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(胸大肌，Pectoralis Major m.)在post30時有較明顯回升，且回升幅度比靜態組更大。雖然動罐組相較於其他兩組在post0時PM和AD(Anterior Deltoid m.)的活化程度有降低的趨勢，但在整體的活化程度上都較為接近mid的值。結論：定罐與動罐組能夠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，使得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。

The purpose of this study is to explore the effects of cupping intervention after muscle fatigue on sports performance and muscle activation levels. Methods: The study enrolled 10 male college students with regular exercise habits, each of whom received interventions for the fixed cupping group, the moving cupping group, and the control group. Participants were excluded if they had upper limb injuries, wounds in the cupping area, bleeding, or were unable to accept the side effects of cupping within the last six months. The experimental process used electromyography (EMG) signal receivers and a dynamometer to measure changes in muscle activation and peak power of plyometric push-ups before and after fatigue, as well as within 30 minutes after the intervention. A one-way repeated measures ANOVA was used to present the trends and differences in changes in sports performance, EMG activation levels, and median frequency. Results: There were no significant differences between fixed and moving cup groups. However, the use of cupping intervention after fatigue showed an immediate effect on power recovery, whether with fixed or moving cups, with the fixed cupping group showing a degree of power recovery closest to the pre-test value at post30. In terms of rate of force development, the fixed cupping group showed an immediate recovery trend after the intervention, but the moving cupping group had the greatest degree of recovery at post30, closest to the pre-test values. For muscle activation, the fixed cupping group showed a more significant rebound at post30, and the rebound amplitude was larger than the static group. Although the moving cupping group showed a trend of reduced PM and AD activation at post0 compared to the other two groups, the overall activation level was closer to the mid-value.Conclusion: The trends in strength recovery and rate of force development produced by the fixed and moving cupping groups may be due to increased muscle activation during cupping, allowing more motor units to assist in force output. Subsequent experiments could further explore the relationship between the level of EMG activation and sports performance to infer whether the phenomenon of increased EMG activation due to cupping intervention has a genuinely positive effect on the recovery from post-exercise fatigue under a fixed experimental method.
