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」。

    武術「發勁」與「化勁」技術機轉之生物力學評估
    (2010/08-2011/07) 張家豪; 黃長福
    背景:「引進落空合即出」記載於拳論，其意為當對方攻來時，利用牽引轉化等化勁的 方式，讓對方的勁力不能攻到己身，並利用對方本身的衝力讓對方失去平衡，進而被我 掌握而加以發勁反擊。本計畫預計以三年時間探討整個結合化、發勁之「引進落空合即 出」技術，藉由動作與肌肉收縮機轉的模式，期能在教學傳承上給予助益。目的:第一 年探討武術中「發勁」動作的肌肉活化機轉，對照運動學與動力學參數，建立出發勁動 作的常模；第二年對武術中防守走化之「化勁」動作進行運動學、動力學與肌電圖分析， 並建立動作常模；第三年探討化勁後發勁—即拳論中『引進落空合即出』的連貫動作， 結合人體運動學參數、地面反作用力與肌電圖的分析，建立動作常模。方法:第一年將 採用Vicon 三維動作分析系統、Kistler 測力板以及Noraxon 肌電圖儀同步收集12 位熟 悉「發勁」技術的武術學習者，對目標物發勁時的運動學、動力學與肌電訊號資料；第 二年亦將採用Vicon 三維動作分析系統、Kistler 測力板以及Noraxon 肌電圖儀同步收 集12 位熟悉「化勁」技術的武術學習者，將對方推力化解時的運動學、動力學與肌電 訊號資料；第三年將採用Vicon 三維動作分析系統、Kistler 測力板以及Noraxon 肌電 圖儀同步收集12 位熟悉「引進落空合即出」技術的武術學習者，將對方推力化解後同 時發勁將對方推出的運動學、動力學與肌電訊號資料。資料將利用弗里曼二因子等級變 異數分析法、卡方檢定進行統計分析，顯著水準定為α=.05。

    Kinetic differences in lower extremity between baseball pitching from pitcher's mound and flat-ground
    (2014-07-16) 黃長福; Po-Chieh Chen; Chen-Fu Huang; Chun-Lung Lin; Bo-Jen Ko
    The purpose of this study was to investigate the kinetic differences in lower extremity between pitching from a mound and flat-ground. A motion capture system and two force plates were used simultaneously to collect the dynamic data of 8 baseball male pitchers. The results revealed that pitching from the mound generated higher propulsive force at the trailing leg as well as greater braking force and vertical ground reaction force at the lead leg (p< .05). The trailing leg in the mound condition generated greater knee posterior joint force while the lead leg had greater axial joint force at ankle and knee, as well as greater extension moment at ankle, knee and hip (p< .05). It was concluded that pitching from the mound generated higher ground reaction force, which resulted in higher joint forces and moments and thus might increase stresses at lower extremity.

    Ground Reaction Force of Baseball Flat Ground Pitching
    (2009-08-21) 黃長福; C. Lin; C.F. Huang
    The purpose of this study was to describe the characteristics of the ground reaction force (GRF) of baseball flat ground pitching, and compares the characters with previous research which pitched on pitching mound. Fourteen division I college pitchers participated in this study. A VICON Motion capture system (10 cameras) and two force platforms were used to collect 3-D kinematic data (500Hz) and GRF data (1000Hz). Three successful trials for each subject were analyzed. The result shows the pivot foot anterior/posterior (AP) propulsive force was larger on flat ground, and the leading foot AP force was larger on pitching mound. The other two components GRF were similar in these two ground situations. The three components of GRF had low correlation with ball velocities. Comparing the peak GRF in three components between pitcher with fast and slow ball velocity groups, the fast velocity group produced a larger leading AP braking force. The leading foot AP breaking force may be an important variable for identify the fast and slow pitching ball velocities.

    Angular analysis of the index and middle fingers during fastball and curveball pitching - a case study
    (2008-07-18) 黃長福; Chung-Lung Lin; Chen-fu Huang; Jia-Hao Chang
    The purpose of this study was to expand the knowledge by quantifying and comparing finger angle between curveball (CB) and fastball (FB) pitching. One division II college pitcher was participated in present study. A VICON Motion capture system were used to collect 3-D kinematic data (500Hz). Three successful trials for each FB and CB were collected. The metacarpal phalangeal joint (MCP), proximal interphalangeal joint (PIP) and distal interphalangeal joint (DIP) angle was analysed. There were several differences in MCP, PIP and DIP angle for CB and FB. But similar patterns were found between index finger and middle finger. This information may beneficial to conduct thefurther study to explore the mechanics of pitching.

    The effect of hand-held weights on standing long jump performance
    (2005-08-27) 黃長福; Chenfu Huang; Hung-ying Chen; Hsiente Peng
    The standing long jump was one of the events in ancient Olympiad Games. Extra weights were held in the hands of athletes during the jump. It has long been debated whether the extra weights were used to make the challenge more difficult or to enhance the jumping performances. The purpose of this study was to investigate the effect of extra weights on standing long jump performance. A Redlake high-speed camera was synchronized with a Kistler force platform to collect the data of eight male jumping performances. The results Indicate that the total horizontal propelling time, time to maximal horizontal force, horizontal impulse and horizontal velocity of body CG at takeoff all increased. with loaded jumps. In addition, the vertical velocity of body CG and angles at takeoff decrease with loadedl weights. It was suggested optimal extra weights for extending standing jump distance is 8% of body mass.
