| Summary: | 碩士 === 國立體育大學 === 運動科學研究所 === 102 === Objective: To compare the difference of extremely joints force between variant sports shoes under difference velocity. Method: In this study, 12 healthy male volunteers were asked to walk and run under self-select speed, each for 30 times, with barefoot and two difference sports shoes respectively. And the data was acquired by 3-D motion capture system and force plate. The inverse dynamic data of ankle joint, knee joint, and hip joint was analyzed by Visual 3D software. One-Way ANOVA was calculated by SPSS 20.0 software, to discuss the difference of lower joint force wearing different shoes. Result: According to the result of this study, sports shoes of NIKE LUNAR have the minimum ankle joint force, knee joint force, and hip joint force, comparing with NIKE FREE and barefoot. The differences between LUNAR and FREE, LUNAR and barefoot are both significantly different (p<.05). Conclusion: Lower joint force is variant with different structure of outsole. And the result indicates the ability of shock absorption of LUNAR is better than FREE.
