本研究目的在比較時下商業健身指導中四種不同類型的深蹲動作，對下肢肌肉活化程度之差異。本研究徵招8名男性大專運動專長生，分別進行(一)傳統法(二)安全法(三)美式法(四)古典法。受試者經過動作指導並練習四種深蹲動作後，予以一組負重為體重之50%的槓鈴；及進行七次的深蹲。每個動作間休息2分鐘。深蹲過程中，以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，紀錄肌肉活化狀況。並透過膝關節角度計，將深蹲動作分期為下蹲期及上升期。擷取計算四條主要肌群在深蹲動作周期的積分肌電值之平均值，透過最大自主收縮肌電進行標準化。結果顯示：美式法在脛前肌的肌活程度顯著低於傳統法、安全法及古典法；但股二頭肌的肌活程度顯著高於傳統法與安全法，其餘臀大肌與股內斜肌，在四種動作間沒有顯著性差異。因此；美式法應可達到健臀蜜大腿效果。

This study was comparing four different commercial techniques and to justify their stimuli to the muscles of lower extremities. 8 college male subjects were recruited and attached with 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. 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).The data then conversed to EMG’s root mean square integration areas of the curve and was normalized with Maximum volunteer contraction (MVC) to the percentages for different movement’s aspect. And the result is that American Hip Squat had a lower muscle activity on TA than Traditional Squat, Safety Squat and Classical Squat; with higher BF activity rather than Traditional Squat and Safety Squat；the rest of the tested muscles－GM and VMO didn’t show differences between different kinds of movements. Therefor, American Hip Squat should present it’s hypertrophy effect.
