Abstract

The aim of this study was to clarify the effect of implementing the new long-jump rule with a takeoff zone, which is currently proposed by World Athletics, on the approach-run and takeoff movements. Ten male collegiate jumpers specializing in horizontal jumping events participated in the experiment. The main finding was no significant difference of effective distances was observed between the proposed and conventional trials. This may due to the fact that no significant differences of maximal horizontal center of mass (COM) velocity, horizontal COM velocity at the landing of takeoff, and takoff angle were observed between the proposed and conventional trials.Therefore, this proposed rule change is expected to only avoid fault trials where athletes touch the ground beyond the take-off line in long jump.
