초록
The purpose of this study was to investigate the effect of performance to stabilization maintenance of muzzle and posture on aiming and firing with position control in 10m air rifle shooting. Participants were 8 male athletic shooter (4 high school shooter, 4 college shooter) with at least three years of experience. For the purpose, the sway of muzzle and posture of shooting was analyzed using three dimensional motion analysis and two force plate with synchronized. The results of this study was appeared that score of shooting was little college group than high school group during the 10 shooting. Sway of muzzle was appeared stable to vertical movement about phase of aiming and firing college group than high school group. Change in the ground reaction force when aiming was less medial movement of anterior foot, the posterior foot of the center of gravity to the rear tended to be more stable support for the body at the college group than high school group. In addition, change in the ground reaction force when firing was tended to be more stable support for the body the posterior foot of the center of gravity to the rear at the college group than high school group. To the results, it was appeared that air rifle shooting can be influenced during aiming and firing with stabilization to the position stability and control ability.
