情境壓力對籃球罰球投籃例行動作行爲一致性與準確性的影響

Purpose: This study was to examine the effects of situational stress on basketball preshot routines behaviors, preshot routines consistency and free throw accuracy via system observation. Methods: Observation via video tape was obtained during the 7 Chinese Basketball Alliance (CBA) play-off games. The measures included sequence of preshot routine, contents of preshort routine and free throw accuracy by different condition for every male player. The one-way repeated measures ANOVA tests was use to analyze data. Results: The finding was that the sequence and contents of preshot routine changed in the 3 conditions of scores. One of six players was maintained at constant level that caused pressure factors on different scores condition. The preshot routine showed no change in the 0-4 and 5-9 scores condition, but sequence of preshot routines had small variation. In above 10 scores condition, players added some content of routine (e.g., spin and pause). Furthermore, the consistency of preshot routines and free throw shooting accuracy were not significant under 3 conditions of scores F (2, 10) = .29 (p＞.05; F (2, 10) = .21 (p＞.05), . Conclusions: The sequence and contents of preshot routine partial changes that caused different scores condition pressure factors. However, neither preshot routines nor free throw accuracy was influenced by situational stress.
