【 摘 要 】

Purpose: To investigate the effects of midsole thickness on non-rearfoot strike runners’redistributions of knee and ankle joint negative and positive work.Methods: Fourteen healthy male runners wore minimalist, traditional, and maximalist shoesand ran in a straight line in each shoe in the laboratory at a speed of 15 km/h, with a ±5%difference being allowed. Whole-body kinematics and ground reaction forces were recorded,and the data of eleven non-rearfoot strikers were used for the analysis. Ankle and knee jointnegative and positive work was calculated by integrating each joint's torque power. Friedmantest was used for statistical comparisons.Results: Minimalist shoes induced significantly greater ankle joint negative and positive workthan in other shoes. Maximalist shoes induced significantly lower ankle joint positive workand greater knee joint negative work than in other shoes, and significantly greater knee jointpositive work than in minimalist shoes.Conclusions: Our results indicated that non-rearfoot strikers redistributed joint negative andpositive work from the knee to the ankle when using minimalist shoes or from the ankle tothe knee when using maximalist shoes. It is recommended that future research employs morerigorous study designs, such as randomised controlled trials and longitudinal studies, toprovide a more accurate assessment of the effect of these shoes on injury rates.
