本研究的目的在編製棒、壘球揮棒擊球動作的測驗，研究對象島國立台灣師大體育系二年級已修習壘球課女生24名o以揮棒擊球的成績表現為效標變項，以揮棒擊球的動作過程為預測變項，運用無母數迴歸分析，其結果為:一、最具代表性的動作要領依次為:1.第6項變項:揮棒時頭部固定眼睛看球。2.第 5項變項:揮棒前由腰帶動的反轉動作。3.第 9項變項:兩肩水平旋轉水平揮棒。4.第13項變項:擊球瞬間兩手腕自然翻轉的時機o 二、原始分數迴歸去式鳥:Xc = 0.43X6 + O.17Xs + O.16X9 + O.15XJ3 + 5.45 三、標準分數迴歸去式為:Zc = 0.43Z6 + O.17Zs + O.17Z9 + O.15ZJ3
英文摘要
The purpose of this study was to develop a hitting test of baseball and softball. Twenty-four female students of Taiwan Normal University who attended softball class in there sophomore year were served as the subjects. Theoutcome hitting performance were used as the criterion and the hitting process was served as the predictors. By applying the nonparametric multiple regression analysis. the results were as follows: A.The most representative variables of the hitting action in sequence were: 1.Variable 6: Holding head still and fixing eyes on the balll. 2. Variable 5: Turning hips slightly back toward the catcher before swing. 3. Variable 9: Rotating shoulders horizontally and swinging bat smoothly. 4. Variable 13: Timing to roll wrists as the bat hitting the ball. B.Theregression equation of raw score is:Xc = 0.43X6 + O.17Xs + O.16X9 + O.15XI3 + 5.45 C.The regression equation of standard score is: Zc = 0.43Z6 + O.17Zs + O.17Z9 + O.15Z13
