Mukwaya Godfrey, Masahiro Marshall Nakagawa, Hiroh Yamamoto · 2007
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. KEY WORDS: tug of war, the loss of team pulling force, pulling direction, straightway Tug of war is one of the team sports where it is important to utilize the maximum force of all players. The team pulling force is about 20 % smaller than sum of force exerted by 8
