三分線距離增加對HBL三分球相關數據之影響

Abstract

目的：本研究旨在探討三分線距離增加對HBL男子與女子球隊三分球相關數據之影響。方法：以獨立樣本t檢定，比較99學年度及100學年度HBL男子組與女子組球隊之三分球相關數據表現。結果：一、男子前八強整體在三分球試投、三分球中籃、三分球命中率等三項數據皆下降，達顯著差異。二、女子前八強整體在三分球中籃與三分球命中率皆下降，三分球試投卻增加，三項數據皆未達顯著差異。結論：三分線距離的增加，確實影響了HBL男子組的三分球相關數據表現；而女子組的試投次數，不減反增，若投中數減少，將會使得命中率也隨之下降。因此，若要能隨時保持最佳運動表現，縮短國際籃球規則改變時所花費的適應時間，建議於投籃訓練時拉遠出手距離，並且增加訓練強度與肌力負荷。

Purpose: The study aims to explore the impact of increasing 3-point line distance on the 3-point shooting performance of the HBL male and female. Method: This research is based on the top 8 male and female teams from HBL. Compared the statistics of 3-point shot from 99 semester year and 100 semester year using independent samples t-test. Analyzed the effect of the increment of 3-point line on the 3-point shot performance of the players. Results: 1. Top 8 male teams decreased 3-point attempts, 3-point made and 3-point percentage with significant differences. 2. The 3-point made and 3-point percentage of the top 8 female teams decreased, while 3-point attempts increased. But none of them reach significant differences. Conclusion: The increment of 3-point line do affect the performance of HBL male 3-point statistics. On the other hand, the attempts made of the female teams increased. The decrement of the number of 3-point made will also lead to the decrement of 3-point percentage. Therefore, in order to keep the best sport performance at any time so that the player adjust quicker to the changing official basketball rules, we suggest to increase the shooting distance while practice and enhance the weight training.
