摘要

本研究以不同重量及分布之負重鞋為主軸，分別以兩個實驗探討男女性別是否影響偏好負重鞋款以及分析在走路步態週期，穿著不同負重鞋款是否影響下肢肌電訊號。本實驗招募40位受試者，男女各20位，實驗一以穿鞋配對比較法方式，讓受試者從五雙負重鞋款選出最偏好一款，實驗二則以肌電訊號儀(EMG)收集受試者以走路方式穿五款負重鞋之下肢肌電訊號。實驗一結果發現性別會影響偏好負重鞋款，男性皆偏好後負重鞋款(負重鞋D&E)，女性則多數偏好後負重鞋款(60%)，實驗二結果則發現男、女穿著不同負重鞋款並不會影響下肢肌肉(RF,LBF,TA,GA)之積分肌電值，其中我們發現下肢積分肌電最小值傾向發生於偏好與穿鞋情境為同一個負重鞋款，因此我們認為男、女偏好不同負重鞋款的影響因子為男女習慣穿鞋款之質量中心的不同以及下肢骨骼排列之差異。

This study focused on walking with different additional weighted shoes. The purpose of this study was to analyze the lower extremity electromyography under wearing different weighted shoes and to find the gender influence on preference of the weighted shoes. Forty subjects (20 males & 20 females) who were used to exercise regularly included in this study. In the first experiment, the subjects were required to choose the most comfortable from five weighted shoes models with paired comparison. In the second experiment, an EMG device was used to simultaneously record lower extremity muscles activity when walking on the treadmill with sampling frequency of 1000/sec. The results of preference test showed that gender would affect preference model of weighted shoes. All male preferred weighted shoe D and E that the weight added on the rear tip of the sole. However, twelve females (60%) preferred shoe D and E, eight females (40%) preferred other shoe models. Gender had no significant influence on iEMG under different weighted shoes conditions. Participants who preferred different weighted shoes would have different muscle activation patterns. It was worthly noted that the minimum iEMG of lower extremity seemed to occur when the particpants wearing their preference weighted shoes. The habit of wearing shoes (COM position) and lower extremity skeletal alignment perhaps are the key factors leading to different weighted shoes preference between the male and female paticipants.
