Abstract
Runners change their running style, e.g. heel strike strategy, to adapt to different shoe conditions [1]. Various mechanisms for adaptation are discussed [2,3]. Alteration of stiffness of the ankle joint at heel strike by dorsiflexion or plantarflexion of the foot seems to be disregarded as mechanism of adaptation. In this study, alterations of heel strike angle (HSA) and plantarflexion velocity (PFV) in the sagittal plane due to wearing different shoe conditions was examined. By this, adaptation in running style as a mechanism of shock attenuation should be investigated.
Highlights
Runners change their running style, e.g. heel strike strategy, to adapt to different shoe conditions [1]
heel strike angle (HSA) and plantarflexion velocity (PFV) show an individual range from 15.3° to 36.1° and 377°/s to 664°/s between subjects and shoes
Low intraindividual variability of subjects was found for all shoe conditions (COVØHSA = 5.4%, COVØPFV = 5.6%)
