一、垂直高度位移
坐墊位置調高,對一般女性的影響為:
膝、踝關節活動度範圍增加,臀大肌、股二頭肌與腓腸肌活化增加。
坐墊位置於中間,對一般女性的影響為:
踩踏效益與低坐墊位置比值相似。
坐墊位置調低,對一般女性的影響為:
各關節活動度下降,膝關節穩定性較佳,下肢雙關節肌群活化降低,踩踏效益 較高。
二、水平前後位移:
坐墊位置調前,對一般女性的影響為:
股四頭肌群活化程度越大。
坐墊位置調後,對一般女性的影響為:
關節活動度增加,膝關節穩定性較佳,腓腸肌活化越大。
建議:本研究建議中間坐墊位置或許比較適合一般女性,建議未來實驗之探討可以 針對前後位置移動距離長短的造成關節受力做分析,能更詳細的了解坐墊位置的調整。
針對肌肉訓練的部分,臀大肌與腓腸肌比較容易受到坐墊位置上下及前後的改變,股四 頭肌群容易受到坐墊位置前後改變的影響,股二頭肌則容易受到坐墊位置上下改變的影 響。或許未來可以參考本實驗結果針對設定要訓練的肌群進而調整適當的坐墊位置。
