ASYMMETRIC CONTRIBUTION OF SUPPORT LEG TO CURVED RUNNING VELOCITY
Keywords: curved running, sprinting, momentum generated, generated force
AbstractThe purposes of this study were to show the support leg contributions in the curved sprinting, and to investigate the differences of contribution between inside and outside legs. Twenty athletes participated in the experiment and ran 60m with maximal effort on the curved path with 41 markers. The trials were recorded by motion capture systems. The relative momentum generated by the support leg and the generated forces were calculated. The asymmetric contributions were found in centrifugal-centripetal component. In the inside leg, the forces to the centripetal direction were generated by the thigh and foot. On the other hand, in the outside leg, the forces to the centripetal direction were generated by the shank and foot. However, the contributions of 3 segments in anteriorposterior and vertical components were similar to the straight sprinting in each leg.
