不同深蹲訓練動作對於下肢肌肉刺激之比較
Lower Extremity Muscular Stimuli from Different Squatting Movements
摘要
本研究目的將比較四種商業健身指導規範中的常見深蹲基本動作之下肢肌肉刺激效果的比較。本研究徵招乙名26歲男性業餘射箭選手，進行四種深蹲法動作檢測：（一）傳統深蹲、（二）最新安全訓練法、（三）美式健體健臀法、（四）古典綜合式訓練法，每週進行一種動作檢測，經過指導練習動作後，進行一組50%體重次數七次的深蹲運動。將Delsys肌電儀黏貼在非慣用腳的臀大肌、股二頭肌短頭、股內斜肌及脛前肌肌腹上，並透過膝關節關節角度計進行深蹲動作分期。結果顯示：古典綜合式訓練法之深蹲動作可產生最多的股內斜肌及股二頭肌短頭之肌肉活化程度，而脛前肌的肌活表現與傳統深蹲法相似。因此，古典綜合式訓練法之深蹲動作更能均衡強化大腿前後側肌力。
並列摘要
This study was comparing four different commercial techniques and to justify their stimuli to the muscles. This study recrewed a 26 year-old subject which is an amateur of arching, and attached Electromyography(EMG)probes at non-dominant leg on different muscles, such as vastus medialis oblique(VMO), biceps femoris short head(BF) and as co-effecting muscles-gluteus maximus(GM) and also tibialis anterior(TA).To exam for four kinds of motion:(1)Traditional Squat (2)Safety Squat (3)American Hip Squat (4)Classical squat. To evaluate different commercial movement's patterns among stages of divided phases; decided by the integrations for a goniometer; we can observe the stimuli from the motion kinds to different squat movements in terms for induce muscle contractions. Subject then first be directed and coached for four different kinds of squatting before he got tested inside of the gym of Taipei University. Each kind of motion tested after the last one and holds 7 times of motions per set(We do only one set). Besides the weight used is 0.5 times of bodyweight(BW). And the result is that the one to two specific movements have much higher muscle stimulus toward thigh's anteriors and posteriors and TA; among this, The best one shown being the one that this study's writer invented in a way to stimulate both the anterior and the posterior sides of thigh.
