為配合我國社會變遷與體育發展及本校的轉型與發展,本學院於90年8月正式成立,並將原屬本校教育學院之體育學系(所)、運動競技學系、運動與休閒管理研究所調整成立運動與休閒學院,並於95學年度增設運動科學研究所:為提升本院競爭力於101學年度運動競技學系與運動科學研究所整併為「運動競技學系」,運動與休閒管理研究所與管理學院餐旅管理研究所整併為「運動休閒與餐旅管理研究所」。

Therefore, it is important to control precisely the distribution of applied forces to the javelin for further distance and tip-first landing. Methods: Two synchronized Redlake high-speed cameras (250 Hz) were used to videotape an elite thrower and a javelin with three fixed non-collinear markers. The aerodynamic and inverse dynamics were taken into account in the 3D dynamic analysis. Rerults: When the hand gripped the javelin, the applied force was mainly distributed to the axial direction. At release, the javelin was controlled by distal parts of fingers, and the distribution of force was changed from the axial to the lateral direction. The lateral torque was significantly larger than the axial torque all the phase. The peaks of lateral and axial torques were 24.08 and 1.31 Nm respectively. Conclusions: The results calculated by the inversed dynamics were similar to those by previous research. In addition, the method adopted in this study is simple and has no interference of connecting wire, which could be used for further javelin research.Item 壘球投手跨步腳著地期間下肢關節之動力學分析(中華民國體育學會, 2001-09-01) 王令儀; 杜惠萍; 林德嘉; 黃長福本研究之主要目的是要藉由地面反作用力以及淨關節間作用力、力矩與功率來了 解疊球投手投擲快速球時跨步腳在著地期間下肢關節承受的負荷及各肢段肌群參與活動的情 形。 以四名國家級女子快速壘球投手為施測對象。 將一塊測力板( 600Hz )與一部 Peak 高速攝影機( 120Hz )同步擷取跨步腳著地期間各運動學與動力學參數, 並以動力學逆過 程算得跨步腳著地期間其踝、膝、髖關節之淨關節間作用力與力矩。實驗結果發現,地面反 作用力第一峰值出現在人體骨骼神經系統產生緩衝反應之前,劇烈的地面反作用力值在下肢 緩衝動作不足的情況下形成強大的壓力與剪力值作用在各關節上,長期訓練的累積可能會使 關節、韌帶與軟骨組織承受不容輕忽的負荷。此外,在運動技術上建議加強膝關節伸肌的離 心肌力可促進著地時的制動技術,讓能量有效的傳導到軀幹,以達高效能的投球表現。
