本研究目的在探討世界一流男女鉛球選手(各十四名)，鉛球推擲時的運動學參數對影響推擲成績的相關研究，其運動學參數(預測變項)包括基本參數與幾何參數。使用統計方法為多元逐步迴歸分析法。 研究結果發現男女鉛球一流選手，在基本變項方面，出手速度與出手角度兩個變項上能有效預測推擲距離，亦驗證拋射體的科學理論；而在幾何變項上，男鉛球選手在旋轉階段的鉛球運行路徑、滑步距離兩個變項上亦有效預測出手速度。而在預測迴歸方面分為 一、基本變項與推擲距離的迴歸方程式為（一）男選手原始分數迴歸方程式為：推擲成績=-24.43+2.82*出手速度+0.10*出手角度；男選手標準化分數迴歸方程式：推擲成績=1.21*出手速度+0.28*出手角度；（二）女選手原始分數迴歸方程式：推擲成績=-17.13+2.51*出手速度+0.10*出手角度；女選手標準化分數迴歸方程式：推擲成績=1.56*出手速度+0.1*出手角度。 二、幾何變項與出手速度的迴歸方程式為：男選手原始分數迴歸方程式：出手速度=12.5+1.37*鉛球加速路徑-1.01*滑步距離；標準化分數迴歸方程式：出手速度=0.43*鉛球加速路徑-0.38*滑步距離。

　　　　　The purpose of this study was to examine the relationships of parameters of the kinematics to distance. Subjects were 14 males and 14 females shot-putters. Parameters(preictors variable)included basic parameters and geometric parameters. The analysis of stepwise multiple-regression was conducted. The results indicated that males and females release velocity and release angle were the effective predictors of the distance of the shot-put in the basic parameters and proved the science theory of the projectiles motion. The second results indicated that males length of trajectory (L.T, rotational phase) and length of glide (L.G, gliding phase) were the effective predictors of release velocity. The basic(geometric)parameters and the distance(velocity) of put predicted regression were as follows: 1.Predicted regression in male S=-24.43+2.82*V+0.10*��,S=1.21* V+0.28��;V=12.5+1.37*(L.T)-1.01*(L.G), V=0.43*(L.T)-0.38*(L.G) 2.Predicted regression in female S=-17.13+2.51*V+0.10*��;S=1.56*V+0.1��
