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」。

    The purpose of the study was to analyze the biomechanics of taekwondo front-leg axekick. One force plates, two synchronized high-speed cameras were used to measure biomechanical parameters in each phase of the front-leg axe-kick. The results included: 1. The average reaction time and movement time were 0.423 sand 0.327 s, which respectively occupied about 56% and 44% of attack time. 2. The maximum velocity of hip, knee and ankle were 1.74 m/s, 5.25 m/s and 7.43 m/s respectively. When the kicking leg touched the target, the velocity of knee and ankle were 0.78m/s, 1.72m1s, and 4.64m1s respectively. 3. The peak vertical GRF and impulse were 0.96 SW and 77.57N-s. For decreasing the movement time, it's suggested that an athlete should increase the power and flexibility of lower extremities during the training section.
