【論文摘要】具有肌力感測與短波治療智慧護膝對肌肉恢復能力的影響
【論文摘要】Effect of muscle strength sensing and short wave therapy knee support on muscle recovery
摘要
研究背景：短波屬於深層的熱治療，具有促進深層血液循環以提升運動後肌肉恢復能力的效果。傳統上，短波儀器屬於大型儀器，會有攜帶不便的問題。本研究將短波技術微小化，並放置於護膝中，探討這樣的設備是否能有效增加肌肉在運動後的恢復能力。本研究目的為探討含有微小化短波的智能護膝，對於深蹲到衰竭後肌肉恢復能力的影響。研究方法：以3名有重量訓練經驗的成年男性為研究對象，隨機區分成短波介入組（Shortwave trial，簡稱ST）或是不開短波的控制組（Control trial，簡稱CT）。受試者首先進行股直肌與股內側肌的最大等長收縮，使用肌電圖（electromyography）測量等長收縮時的肌電訊號。執行完成後，受試者使用85%最大肌力的重量進行深蹲，直到衰竭。ST組在衰竭後會開啟短波治療20分鐘，CT組則是不開啟短波，坐著休息20分鐘。在休息之後，重新測量股直肌與股內側肌的最大等長收縮，使用Wilcoxon符號檢定比較重訓前後兩組之間的最大等長收縮肌電訊號比值。結果與結論：在訓練到衰竭後，兩組的最大等長收縮比值在股內側肌（p=0.109）和股直肌（p=0.9）並沒有顯著差異。使用微小短波介入並不會影響衰竭運動後的肌肉恢復能力。

Introduction: Short wave is a deep heat therapy, which has the effect of promoting deep blood circulation to enhance muscle recovery after exercise. Traditionally, short-wave devices are large devices that are inconvenient to carry. In this study, the short wave technology was miniaturized and placed in a knee support to investigate whether such a device could effectively increase muscle recovery after exercise. The purpose of this study is to investigate the effect of intelligent knee pads containing miniaturized shortwave technology on muscle recovery after squatting to exhaustion. Methods: Three adult males with weight training experience were randomly divided into a shortwave trial (ST) and a control trial (CT). The subjects first underwent maximum isometric contraction of the rectus and medial femoral muscles, and electromyography was used to measure the electromyographic signals during the isometric contraction. After performing the electromyography test, subjects performed squats with a weight of 85% of maximum muscle strength until failure. The ST trial turning on shortwave therapy for 20 minutes after failure and the CT trial resting for 20 minutes without turning on shortwave. After rest, the maximum isometric contraction of the rectus femoris and medial femoris muscles were re-measured and the maximum isometric signal ratios between the two trials before and after the training were compared using Wilcoxon sign verification. Results & Conclusions: After training to failure, the maximum isometric contraction ratio did not differ significantly between the two trials for the medial femoral muscle (p=0.109) and the rectus femoris (p=0.9). The use of miniaturized shortwave interventions did not affect muscle recovery after exhaustion.
