摘要

本研究針對個案跑者穿著不同釘數釘鞋於踏板進行蹲踞式起跑時，後腳的生物力學參數進行分析，以了解不同釘數釘鞋對於跑者起跑之影響。實驗以1名男性大專院校田徑運動選手為受試者，使用VICON動作分析系統（6部M2攝影機，取樣頻率250Hz；1塊AMTI測力板，取樣頻率1000Hz）進行資料結果與分析。結果顯示受試者穿著不同鞋釘數釘鞋起跑時：（一）起跑反應時間和後腳推蹬踏板時間無明顯差異。（二）向後踩踏板力量最大值、向後踩踏板力量最大斜率、踩踏板之摩擦係數、踩踏板與足部蹠屈動作力矩最大值均以穿著8釘釘鞋最大、5釘釘鞋次之、7釘釘鞋最小；但向後踩踏板力量之衝量無明顯差異。（三）後腳髖、膝關節各項角度曲線數值無明顯差異；踝關節角度曲線數值以穿著8釘釘鞋的後腳踝關節角度曲線最大值較穿著5、7釘釘鞋數值來的大；至於起跑第一步步長則無明顯差異。由上述結果可知，受試者穿著不同鞋釘數釘鞋起跑時，有多個力量參數結果呈現規律性差異，因此建議受試者未來在進行訓練時以穿著8釘釘鞋或者5釘釘鞋為優先。在未來研究部分，可使用足底壓力分析來了解受試者穿著釘鞋起跑時，足部是否有特定的用力方式；另外也可增加受試者並且擴大分析受試者在起跑之後的動作。

In this study, a subject was aimed to analyze biomechanic parameters of his rear foot when wearing running shoes with different number spikes on pedal to do crouching starts. In experiment, one track & field male player from college was recruited as subject. VICON motion analysis system (six M2 cameras, sampling rate: 250Hz; one AMTI force plate, sampling rate: 1000Hz) was used to gather and analyze data. Results when the subject wearing running shoes with different number spikes to do crouching starts showed: (1). The reaction times and the times of rear foot pushing pedal were not different. (2). The results of maximum force to push pedal backward, maximum force slope when the force pushing pedal backward, friction coefficient when the force pushing pedal and maximum torque when the subject’s rear foot to push pedal and to do plantar flexion between running shoes with different spikes were different. Moreover, the orders of these results were wearing shoe with eight spikes was the biggest, wearing shoe with five spikes was mid and wearing shoe with seven spikes was the least. As for the results of impulse when force to push pedal backward, these impulse results between running shoes with different spikes were not different. (3). Hip and knee joint’s angle curve values were not different. But ankle joint angle curve values between shoes with different spikes were different. The value of shoe with eight spikes was bigger than the values of shoe with five and seven spikes. As for the length of the first steps, these results were not different. By these results, we could understand several force parameters were different regularly when the subject wearing running shoes with different number spikes. So wearing running shoes with eight spikes or five spikes to train was suggested for the subject. As for the future study, foot pressure analysis could be used to understand the subject’s specific way of rear foot to push pedal. Moreover, more subjects could be recruited and more motions after crouching starts could be analyzed.
