TEAM PULLING TECHNIQUE OF THE TUG OF WAR -A BIRDS-EYE ANALYSIS OF TOW

Abstract

The purpose of this study was to clarify the loss of the force on first 1 second of drop phase for Japanese female elite tug of war team from view point of a backward pulling direction. In order to examine the pulling movement, performances of 10 teams in 2006 All Japan Tug of War Championship tournament were videotaped from directly above the lane by digital video camera located near the ceiling of gymnasium. The team slanting angle was measured by using two-dimensional motion analysis system. About 0.5 % of team pulling force was wasted in first drop phase for female elite tug of war team. This is small compared with total loss of the team pulling force (about 20%. Liou et al. 2005). The lateral slanting has likely no relation with the loss of the force in drop phase.
