Abstract

The purpose of this study was to clarify the effect of the presence or absence of upper limb movement on the propulsion direction body velocity (TPV) leaving the platform at kick start. The first trial (Standard trial) is a normal kick start, and the second trial (Lower trial) is the same as a normal kick start. The force from the upper limb movement at the time was set so that the start table was not applied, and the start movement calculated the 3D coordinates of the marker attached to the body by 3D movement analysis. As a result, in the movement speed at the time of leaving the platform, the standard trial had a significantly higher value in the propulsion direction and a significantly lower value in the vertical movement speed than the lower trial. In addition, since the standard trial had a significantly lower value in the jumping angle when leaving the platform, the role of the upper limb movement in kick start is to promote by making the jumping angle closer to the horizontal when leaving the platform. It was suggested that it may affect the directional velocity.
