摘　　要：Purpose:The purpose of this study was to determine the effects of 12 weeks of barefoot running on foot strike patterns,inversion-eversion and foot rotation in long-distance runners.Methods:Thirty-one endurance runners with no experience in barefoot running were randomized into a control group and an experimental group who received barefoot training.At pre-test and post-test,all subjects ran at low and high self-selected speeds on a treadmill.Data were collected by systematic observation of lateral and back recordings at 240 Hz.Results:McNemar’s test indicated significant changes(p <0.05) in the experimental group at both high and low speed running in foot strike patterns,reducing the percentage of high rearfoot strikers and increasing the number of midfoot strikers.A significant increase(p <0.05) of external rotation of the foot and a decrease of inversion occurred at comfortable speed in the experimental group.Conclusion:Twelve weeks of barefoot running,applied progressively,causes significant changes in foot strike pattern with a tendency toward midfoot or forefoot strikes,regardless of running speed and significant changes in foot rotation at low speed,while the inversion was reduced in left foot at low speed with a tendency toward centered strike.Purpose:The purpose of this study was to determine the effects of 12 weeks of barefoot running on foot strike patterns,inversion-eversion and foot rotation in long-distance runners.Methods:Thirty-one endurance runners with no experience in barefoot running were randomized into a control group and an experimental group who received barefoot training.At pre-test and post-test,all subjects ran at low and high self-selected speeds on a treadmill.Data were collected by systematic observation of lateral and back recordings at 240 Hz.Results:McNemar’s test indicated significant changes(p <0.05) in the experimental group at both high and low speed running in foot strike patterns,reducing the percentage of high rearfoot strikers and increasing the number of midfoot strikers.A significant increase(p <0.05) of external rotation of the foot and a decrease of inversion occurred at comfortable speed in the experimental group.Conclusion:Twelve weeks of barefoot running,applied progressively,causes significant changes in foot strike pattern with a tendency toward midfoot or forefoot strikes,regardless of running speed and significant changes in foot rotation at low speed,while the inversion was reduced in left foot at low speed with a tendency toward centered strike.
