摘要

本研究目的為探討三種不同助跑型式訓練（站立、墊步以及交叉步）對7-12歲男童過肩投擲動作型式及投擲距離的影響。共計80位7-12歲男童以三種助跑方式分別進行用力過肩擲遠，配合高速攝影機(120Hz)記錄動作型式，並以單手用力過肩投擲形式評量表為工具分析動作型式，以二因子變異數分析探討年齡與助跑型式是否在投擲距離及投擲動作型式上有顯著差異。所得結果在投擲距離方面，10歲與12歲男童交叉步及墊步投擲距離顯著優於站立投擲距離；在投擲動作型式方面，9-12歲組的動作型式分數均顯著優於7歲組，不同助跑形式之間則無顯著差異。本研究結論為10歲與12歲男童在交叉步及墊步助跑方面所獲得的利益可以延續到投擲距離表現上，但交叉步與墊步助跑之間則無顯著差異。未來建議可以在10歲與12歲男童的投擲教材（如國小體育領域教材）上放入投擲墊步及交叉步助跑教學內容，但不需要特意強調採用交叉步助跑。

The purpose of this study was to examine the effects of three approaching steps (standing, approach pad steps and approach across steps) on overarm throwing for 7-12 years old boys. Eighty boys aged 7-12 years old were served as participants for this study. Participants were required to practice throwing for 300 times, including three different approaching steps of overarm throwing. The throwing patterns were simultaneously acquired by using a high-speed camera (JVC 9800) with sampling frequencies 120 Hz. The attained data were evaluated using the Burton's amendment (1992) of development sequences for overhand throw. Two-way ANOVA was used to examine the difference of distance and throwing patterns among age and approaching steps. The result were as the followings; 1. The throwing distances of approach pad steps and approach across steps were significantly better than standing for the boys aged at 10 and 12 years old. As for the throwing patterns, the scores of boys aged from 9-12 years old were significantly higher than the boys aged at 7 years old. However the scores among three approaching steps didn’t achieve the differences significantly. It was concluded that the boys aged 10-12 years old could take the advantage of pad steps and approach across steps to make throwing performance better. These results suggest that boys aged from 10-12 years old could be provided with the instruction of approach pad steps and approach across steps for overarm throwing movements, but no need to emphasize the use of the approach across steps.
