Abstract

This study examined the effects of length and movements of preshot routines on free throw shooting in basketball. 17 members of an intercollegiate men's basketball team attempted 20 free throws in each of four different conditions: (1) normal routine and time, (2) normal routine with altered time, (3) altered routine with normal time, and (4) altered routine with altered time. Free throw performance was measured using an objective 5-point scoring system. A multivariate analysis of variance indicated a significant effect for routine. Neither time nor routine by time was significant. Results indicated that altering the movements in the routine had a significant effect on performance while lengthening the time did not.

摘要

本研究考察了投篮前常规动作的时长和动作对篮球罚球的影响。一支大学男子篮球队的17名队员在四种不同条件下各进行20次罚球：（1）正常常规动作和时间；（2）正常常规动作但时间改变；（3）常规动作改变但时间正常；（4）常规动作和时间均改变。罚球表现采用客观的5分制评分系统进行衡量。多因素方差分析表明常规动作有显著影响。时间以及常规动作与时间的交互作用均不显著。结果表明，改变常规动作中的动作对表现有显著影响，而延长时间则没有。
