本研究目的是利用不同慣用腳評定方式(踢球、登階、跳遠、往前踩步、恢復平衡、銳劍防衛和個人喜好等七項)來分別探討慣用腳和非慣用腳在靜態平衡能力、對地反作用力和速度之差異性,並發現不同評定方式的信度(個人喜好除外)以及相互之問的差異性。以48位下肢或臀部無病史的一般男性大學生為受試對象,其中24位是用來求出慣用腳評定方式的信度,另外24位是用來求出慣用腳和非慣用腳在靜態平衡能力、對地反作用力和速度之差異性,並找出不同評定方式相互之間的差異性。本研究以重測法考驗其信度,並以t考驗比較各種慣用腳評定方式中,慣用腳和非慣用腳之差異性,最後再以單因子變異數分析不同慣用腳評定方式的差異性。結果發現:(一)一般人有所謂的慣用腳,可歸因於「習慣」使然。(二)一般人的慣用腳和非慣用腳在對地反作用力、單腳站立平衡和踢腿速度三項上並無差異性。本研究結果顯示,無法利用任一種方式找出何腳在對地反作用力、平衡能力或踢腿速度上有其優異性。
This study examined the different effects the dominant legs and the non-dominant legs caused on the static balance, the ground reaction and the speed by the seven evaluation methods of the dominant legs: ball-kick, step-up, hop-for-distance, step-forward, balance-recovery, fencing in epee, and the individual preference. This study also examines the differences of the reliability of the six evaluation methods (except the individual preference) and the seven methods of the dominant legs. The subjects were 48 male college students without any anamnesis of legs and bottoms. Twenty-four of them were tested for reliability of the six methods of the dominant legs (except the individual preference), and the other twenty- four were tested to discover the different effects of the dominant legs and non-dominant legs on the static balance, the ground reaction and the speed, to pursue the correlation among the seven evaluation methods. This study used the repeated measures to verify its reliability, and ttest to compare different effects of the dominant leg and non-dominant leg on different kinds of evaluation methods. Finally, ANOVA was used to analyze the difference between the seven evaluation methods of the dominant leg. The result showed: (1) people had their dominant (preferred) legs, which could be attributed to their habits; (2) there was no significant difference in ground reaction force, balance with a single leg, and the kicking speed between the dominant and the non-dominant leg, and (3) since there was no significant difference between the dominant and the non-dominant legs; none of the above seven methods could be used to find which leg (dominant or non-dominant) had its superiority in force, balance or speed.
