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」。

    老年人跨越不同高度障礙物之生物力學分析
    (2005) 邱顯光; Hsien-Kuang Chiu
    在步態中跨越障礙物以及較差的身體平衡感,是最常引起老人跌倒的兩個因素。本研究目的在探討老人步行時跨越不同高度障礙物動作,對步態重心平衡及下肢神經肌肉調控的影響。實驗受試者為各10位健康年輕人(平均年齡20.9±1.73)與健康老年人(平均年齡73.5±4.06)。實驗要求受試者自我配速行走約六公尺後,跨越不同高度之障礙物;本實驗的障礙高度分為四個層級,即無高度、低高度(5公分)、中高度(20公分)與高高度(35公分)。利用一塊測力板(1200Hz)、一台Redlake高速攝影機(60Hz)和Biovision肌電圖儀器(1200Hz)等,進行各項參數收集。以混合設計二因子變異數分析檢定四種高度與兩組受試者之各項力學參數差異顯著性,統計水準定為α = .05。經分析後主要的研究結果為: 一、在跨越較高障礙物的單腳支撐期間,受試者增加重心垂直移動、減少向前重心線動量,並在身體重心與壓力中心平衡穩定的限度內,增加重心與壓力中心間距(p<.05),使身體通過障礙物。 二、在跨越較高障礙高度時,受試者在單腳支撐期因跨越動作改變致使下肢肌肉收縮順序有所改變;此外,老年人在擺動期對股直肌與腓腸肌有較高肌肉活化需求之傾向。 三、老年人跨越漸增障礙高度時,有其獨特的跨越策略:(1)縮短步幅長度並增加垂直位移,(2)減少向前重心線動量(p<.01),(3)增加跟隨腳跨越前足尖與障礙物距離(p<.001),以順利通過各種障礙高度。

    Better postural control during accurate shooting in elite female basketball players
    (2011-07-01) 黃長福; Yen-Ting Wang Wang; Tsung-Li Tseng; Lin Chi; Chen-fu Huang; Pao-Cheng Lin; Alex J.Y. Lee
    The purpose of this study was to evaluate the differences of postural control (PC) during accurate and inaccurate shooting in elite female basketball players. 21 female professional basketball players recruited as subjects. The PC was evaluated by the Accusway as sway radius, velocity, radial and 95% area of the center of pressure (COP) during standard penalty line shooting. The results showed that the COP sway area during accurate shooting was significantly smaller than during inaccurate shooting (74.0 � 37.9 vs. 110.6 � 49.1, p < .05). Moreover, no significant differences were found between situations in the COP radius and velocity. This study found that during the accurate shooting, elite female basketball player had better PC which demonstrated that significant smaller COP sway area than inaccurate shooting.
