本研究利用分段計時器及無線心率計，記錄並從完成時間和心跳率變化，探討穿不同後負重羽球鞋（負重50g、100g、150g、200g、250g）對大專羽球運動員從事基本基本步法之影響。本研究招募 40 位不同球技水準（校、系隊）、性別的大專羽毛球運動員完成兩個實驗，實驗一是以成對比較的方式，找出參與者可以正確辨識重量差異的閾值，正確辨識的分數越高表示對重量差異的敏感度越好；實驗二是基本步法測試，透過分段計時器及無線心率計，分別記錄完成指定基本步法所需的時間及心跳率。重量辨識的結果顯示，女性（8.39±3.86分）在重量差異敏感度高於男性（5.55±2.24分）達顯著差異（p< .05），多數女性在鞋重差異100g時可以正確辨識，多數男性要超過150g以上的差異才能正確辨識。完成指定步法所需時間結果顯示，校隊顯著比系隊快（p< .05），男性顯著比女生快（p< .05），當負重超過50g，完成步法時間與未負重達顯著差異（p< .05），且負重越重完成時間越久；不同的球技水準和性別在心率的改變率表現未顯著差異（p> .05），心率的改變量在負重超過50g時，與未負重狀況達顯著差異（p< .05），且開始測試後10秒（t10）的心跳上升率即達顯著差異（p< .05）。因此，在未能感受鞋重量的差異下，本研究建議女生宜可穿著負重150g以下，而男生穿著負重200g以下的後負重鞋，進行10秒以上的步法訓練，方能達到訓練效果。

關鍵字：後負重鞋、重量辨識、基本步法、心跳率

In this research, segment timer and wireless heart rate monitor were used to measure the complete time and the change of heart rate. Including varsity and department team players with different genders, forty university badminton players were recruited in the experiment. Participants were asked to wear the rear-weighted shoes with 50, 100, 150, 200 and 250g added mass to finish designated tasks. There were two experiments in this study. In the first experiment, participants were asked to discriminate which testing shoes were heavier or lighter by using paired comparison method. The result showed that there was no difference between varsity players and department team players but significant difference between males and females. The correct discrimination rate of the female group was higher than the male group. The threshold of weight discrimination of males was 150g~200g and females was 100g~150g. In the second experiment, participants were asked to do designated footwork on the badminton court with a wireless heart rate monitor. Compared to non-weighted testing shoes, the result shows that participants took more time when testing shoe added over 50g (p< .05). The variation of heart rate rose significantly when testing shoe added over 50g (p< .05). Heart rate rose up apparently while participants were doing footwork over 10 seconds with rear-weighted shoes. It seemed that rear-weighted shoes bring more loading and increase the training intensity.
