Résumé / Abstract

In order to further compare shod versus barefoot running, 35 subjects ran two bouts of 4 minutes at 3.33 m.s-1 on a treadmill dynamometer. Parameters were measured on about 60 consecutive steps. Barefoot showed mainly lower contact and flight time (p<0.05), lower passive peak (1.48 versus 1.70 body weight, p<0.05), higher braking and pushing impulses (p<0.05), and higher pre-activation of triceps surae muscles (p<0.05) than shod. It was concluded that when performed on a sufficient number of steps, barefoot running leads to a reduction of impact peak in order to reduce the high mechanical stress occurring during repetitive steps. This neural-mechanical adaptation could also enhance the storage and restitution of elastic energy at ankle extensors level.
