ABSTRACT

This study aimed to examine the reliability and the time-of-day effect of the 505 change of direction (CoD), 10-m sprint, and change of direction deficit test (CoDD). At two different time of days, 39 young diurnally active physical education male students performed different physical tests: 505 CoD, and sprint tests. Measurements were taken at two separate testing sessions, i.e. in the morning (07:00–08:30 h) and early evening (17:00–18:30 h) in a randomized and counter-balanced setting on nonconsecutive days in 21 of them (21.5 ± 1.5 y of age). The results showed that the 505 CoD test, 10-m sprint, and CoDD performances were a reliable test, and performances were better in the evening the 505 CoD, 10-m sprint, and CoDD testing provided reliable and sensitive scores. In addition, phase 2 showed that CoD, speed, and CoDD are affected by the time of day.

摘要

本研究旨在检验 505 方向变化 (CoD)、10 米冲刺和方向缺陷变化测试 (CoDD) 的可靠性和时间效应。在一天中的两个不同时间，39 名昼夜活跃的年轻体育男学生进行了不同的体能测试：505 CoD 和冲刺测试。测量是在两个独立的测试阶段进行的，即在随机和平衡的环境中，在 21 天的随机和平衡环境中，即早上 (07:00–08:30 h) 和傍晚 (17:00–18:30 h)他们（21.5 ± 1.5 岁）。结果表明，505 CoD 测试、10 米冲刺和 CoDD 性能是可靠的测试，晚上的性能更好，505 CoD、10 米冲刺和 CoDD 测试提供了可靠和敏感的分数。此外，第 2 阶段表明 CoD、速度、
