國內女子鉛球運動員上肢肢段長度與運動表現之相關

Correlation between upper arm length and athletic performance on female shot putters in Taiwan

目的：分析國內女子鉛球運動員上肢肢段長度與運動表現之相關。方法：以24位女子鉛球運動員為受試對象，所有受試者接受上肢肢段長度之測量，包括指距、手臂長及手掌長，所得之數據以Pearson相關績差分析女子鉛球運動員各上肢肢段參數與運動表現之相關。結果：本研究所測得之肢段長度分別為指距169.75 ± 5.99公分,手臂長62.95 ± 3.19公分,手掌長18.29 ± 0.69公分及專項運動表現12.67 ± 1.37公尺。經相關績差分析後發現，上肢各肢段長度參數中，指距及手臂長與運動表現達顯著相關。結論：本研究結果發現女子鉛球運動員上肢肢段長度參數中，指距及手臂長與專項運動表現有顯著相關。

Purpose: This study aims to analyze and explore correlation between upper arm length, and athletic performance on female shot putters in Taiwan. Methods: A total of twenty-four female shot putters was recruited and parameters of length of upper arm including arm span, length of upper arm, and palm size were recorded and analyzed using Pearson’s correlation. Results: Limb segment parameters measured in cm and the results have shown that arm length were 169.75 ± 5.99 centimetres, arm length of upper arms were 62.95 ± 3.19 centimetres, and palm sizes were 18.29 ± 0.69 centimetres while athletic performances reported 12.67 ± 1.37 meters. Statistically significant differences using Pearson’s correlation coeddicient were yielded among arm span, upper arm length and athletic performance. Conclusions: This study revealed significant correlation among limb segment parameters of upper arm including hand length, arm length, and athletic performance.
