在羽毛球比赛中，短双打发球要求准确，而长单打发球也要求有力。8名男子羽毛球运动员在08：00、14：00和20：00完成两次熟悉训练，并在训练时间上进行平衡。在每个阶段，受试者进行10次热身服务，然后是10个短和10个长的测试服务。1平方米的黄色网格被放置在受发球方的发球区前面（短发球）或球场后面沿着中线（长发球）。受试者通过将球尽可能靠近目标网格的一个角落来获得发球的“命中”。准确性通过计算发球的平均径向误差（RE）进行评估，一致性通过计算RE的标准差进行评估。数据通过ANOVA进行分析，温度存在时间效应（p < 0.0005），握力存在时间效应（p = 0.052）。在14：00时，“命中”的准确性最高（p < 0.05），短发球的准确性高于长发球（p < 0.0005）。发球次数对短发球有显著影响，受试者在较晚的发球中更准确（p = 0.036）。结果表明，两种方法的一致性差异不显著（p > 0.05）。总之，在温度和长期和短期服务的准确性方面缺乏一致性表明，除了体温之外，在清醒时间过程中恶化的一些因素可能参与确定测量任务的准确性。
In badminton, the short doubles serve requires accuracy, whereas the long singles serve also requires power. The present study investigated if there are time-of-day effects for these two types of serve.Eight male badminton players completed two familiarization sessions before being tested at 08: 00, 14: 00 and 20: 00 hours, the session times being counterbalanced. At each session, subjects performed ten warm-up serves, followed by ten short and ten long test serves. A 1 m 2 yellow grid was placed at the front of the recipient's service box ( short serve) or at the back of the court along the centre line ( long serve). Subjects scored 'hits' with their serves by putting the shuttle in the grid as close as possible to one corner of the target grids. Accuracy was assessed by calculating the average radial error ( RE) of the serves, and consistency by calculating the standard deviation of the RE. Data were analysed by ANOVA.There was a time of day effect for temperature (p < 0.0005) and a trend in this for grip strength (p = 0.052). The accuracy of the 'hits' was highest at 14:00 hours (p < 0.05) and the short serve showed greater accuracy than the long serve (p < 0.0005). There was a significant effect of serve number with the short serve, subjects getting more accurate with later serves (p = 0.036). No significant variation in consistency was found (p > 0.05). In summary, the lack of agreement in profiles for temperature and the accuracies of long and short service suggests that some factor(s) that deteriorate during the course of the time spent awake might be involved, in addition to body temperature, in determining accuracy in the tasks measured.
