摘要

目的：本研究探討騎乘不同市售坐墊分別對男性及女性對下肢肌肉活化程度和騎乘舒適度之影響。方法:本研究招募6名大專男性（平均身高：175.12±2.44公分、平均體重70.24±5.54公斤、平均年齡20.6±1歲）及6名大專女性（平均身高：160.13±5.26公分、平均體重55.32±3.24公斤、平均年齡21.3±1歲）6個月內無下肢骨骼肌肉及神經系統之傷害，利用肌電儀及舒適量表比較不同性別騎乘兩種不同坐墊寬度設計（男用143mm與女用155mm坐墊）下肢肌肉活化程度（股內側肌、股外側肌、股直肌、股二頭肌、脛前肌、腓腸肌）、及填寫主觀舒適量表，顯著水準定為α=.05。結果：兩種不同市售坐墊設計對不同性別下肢肌肉活化程度及舒適度均沒有顯著差異。結論：目前市售之自行車坐墊無法有效提升騎乘效益及舒適度。

Purpose: The study aimed at investigating different market available saddle to male and female's lower limb muscle activation and personal perception. Methods: The study recruited six male college students as participants (mean height: 175.12±2.44cm, weight: 70.24±5.54, age: 20.6±1 year-old) and six female college students (mean height: 160.13±5.26 cm, weight: 55.32±3.24, age:21.3±1 year-old). None of any participants suffered from neuromuscular injuries in lower limb in the past six months. The electromyography was instrumented to access lower limb muscle activation (Vastus medialis, Vastus lateralis , Rectus femoris, Biceps femoris, Tibialis anterior, Gastrocnemius) of riding two saddles with different width (male: 143mm, female: 155mm), the PRE was utilized to access the comfort of different saddles. The significant level was set as α=.05. Results: No significant difference was observed between two saddles and PRE measurement. Conclusion: Market available saddle were not able to enhance cycling efficacy and comfort.
