Heel impact forces during barefoot versus minimally shod walking among Tarahumara subsistence farmers and urban Americans

摘要

Despite substantial recent interest in walking barefoot and in minimal footwear, little is known about potential differences in walking biomechanics when unshod versus minimally shod. To test the hypothesis that heel impact forces are similar during barefoot and minimally shod walking, we analysed ground reaction forces recorded in both conditions with a pedography platform among indigenous subsistence farmers, the Tarahumara of Mexico, who habitually wear minimal sandals, as well as among urban Americans wearing commercially available minimal sandals. Among both the Tarahumara ( n =?35) and Americans ( n =?30), impact peaks generated in sandals had significantly ( p
