摘要
06年任天堂公司推出Wii這種革命性之遊戲概念，包含拳擊遊戲在內的Wii Sport在全球創下千萬套銷售量，然其遊戲設計與運算上不能估計拳重、且其在拳種的判定上還相當粗糙。因此有必要觀察出拳之生物力學表現與出拳拳重之相互關係，以輔助其做拳重與拳種之判定。
以VICON 460動作截取系統與兩塊AMTI OR6-5-1000以及一顆AMTI MC6-6-2000之荷重元記錄於台南市拳擊委員會等處受訓之九位程度不等之拳擊選手做刺拳以及主直拳之出拳動作、拳力與地面反力。
結果顯示全體而論，刺拳拳力與肩關節速度（0.852）、手掌加速度（0.544）、肘關節加速度（0.702）有相當之正相關性，而主直拳則與手掌（0.764）、肘（0.672）、肩（0.650）關節速度有正相關。而資深組之刺拳拳力則與肩關節速度有最高之相關性（0.933），而與手掌（0.632）、肘（0.655）、肩（0.636）關節加速度有正相關；主直拳拳力則與手掌速度（0.810）、髖關節加速度（0.840）有最高相關性。資淺組在刺拳的肩關節速度（0.796）、手掌加速度（0.776）、肘關節加速度（0.889）有正相關，且主直拳的肘（0.748）、肩關節速度（0.769）以及手掌（0.743）、髖關節加速度（0.750）皆有正相關性。而動力學模型顯示出拳擊中目標之反力會在腕、肘關節造成相當之力矩，但資深組能有效將其分散至不同軸向。同時顯示資淺組之主直拳肩關節在水平外展方向之出力顯著小於刺拳(p<0.05)。

ABSTRACT
The Nitendo published the wii on 2006. Wii was revolutionary game. The wii sports had sold almost 20 million set on the world. Nevertheless, the game can’t calculate the punch force and judge motion rough. Therefore, we need to observe the connection between the biomechanical parameter and the punch force.
The study used the VICON 460 motion caption system and a AMTI MC6-6-2000 load cell to measure the punch motion and punch force. The nine subject was well training from Tainan boxing association.
Result showed the punch force of jab was had positive correlation with the shoulder joint velocity(0.852),hand acceleration(0.544)and elbow acceleration(0.702). And the straight had positive correlation with velocity of hand（0.764）elbow（0.672）and shoulder(0.650). The jab punch force of senior group had the greatest positive correlation with shoulder joint velocity(0.933), and the senior group straight punch force had positive correlation with hand velocity(0.810)and hip joint acceleration (0.840).The jab punch force of junior group had positive correlation with shoulder joint velocity(0.796),hand acceleration(0.776) and elbow acceleration(0.889), and the junior group straight punch force had positive correlation with shoulder velocity (0.769) and hip acceleration(0.750). The dynamic model showed the punch force had make torque on wrist and elbow. The torque of senior group shoulder joint with straight punch on horizontal abd/add axis is significance (p<0.05)small than jab.
