The purpose of this study was to investigate whether maximal muscle power production in humans is influenced by the habitual time of training to provide recommendations for adapting training hours in the month preceding a competition. Sixteen participants performed maximal brief squat and countermovement jumps and short-term cycle sprints tests before and after 5 weeks of training. Subjects were randomly assigned to either a Morning-Trained Group (MTG, 7:00-9:00 hr) or an Evening-Trained Group (ETG, 17:00-19:00 hr). They trained and performed the evaluation tests in both the morning and evening in their naturally warm and moderately humid environment. The results indicated a significant increase in performance (approximately 5-6% for both tests) after training for both groups but failed to show any time-of-day effect on either performance or training benefit. These findings could be linked to the stabilization of performances throughout the day because of the passive warm-up effect of the environment. In summary, our data showed that anaerobic muscle power production could be performed at any time of day with the same benefit.
本研究旨在探讨人类的最大肌肉力量产生是否受到习惯性训练时间的影响，以便为在比赛前一个月适应训练时间提供建议。16 名参与者在 5 周的训练前后进行了最大短蹲和反跳以及短期循环冲刺测试。受试者被随机分配到早晨训练组（MTG，7:00-9:00 小时）或傍晚训练组（ETG，17:00-19:00 小时）。他们在自然温暖且适度潮湿的环境中，在早晨和晚上都进行训练和评估测试。结果表明，两组的表现都有显著提高（大约为两个测试的 5-6%），但没有显示出任何时间对表现或训练效果的影响。这些发现可能与环境的被动热身效应导致全天表现稳定有关。总之，我们的数据表明，在一天中的任何时间进行无氧肌肉力量产生都可以获得相同的益处。
