The purpose of this study was to investigate the effects of time-of-day and morning vs. evening chronotype on the relationships between mood state and performance of extreme intensity cycling exercise. A quasi-experimental between-groups design was used to test the hypothesis that there would be an effect of time-of-day on mood state and physical performance, that mood state and physical performance would be interrelated, and that the relationships would be influenced by participants' morning . evening chronotype. From 74 university students who volunteered, 7 were identified as morning types (M-types) and 7 as evening types (E-types). They completed the Profile of Mood States (POMS) questionnaire and performed a 30 s Wingate test on three different days, once at 08h00, once at 14h00, and once at 20h00. The main performance measure, work done in the Wingate test, increased across the day (16.4 ± 4.8 kJ < 17.0 ± 5.0 kJ < 17.6 ± 5.2 kJ; < .01). For the M-types, individual changes in performance from the morning to the afternoon were correlated with individual changes in the POMS score for vigor ( = 0.81; = .03) and changes in performance from the afternoon to the evening were correlated with individual changes in fatigue ( = - 0.85, = .02). For the E-types, the opposite was true, as morning-to-afternoon changes in performance were correlated with individual changes in fatigue ( = - 0.70, = .08) and afternoon-to-evening changes in performance were correlated with individual changes in vigor ( = 0.78, = .04). Results demonstrate a time-of-day effect on morning . evening chronotype-dependent relationships between mood state and cycling performance.
这项研究的目的是调查时间和晨型/晚型对情绪状态与高强度间歇骑行运动表现之间关系的影响。采用准实验分组设计来检验以下假设：时间对情绪状态和身体表现有影响，情绪状态和身体表现相互关联，并且这种关系会受到参与者晨型/晚型的影响。从 74 名自愿参加的大学生中，确定了 7 名晨型（M 型）和 7 名晚型（E 型）。他们在三天内完成了心境状态问卷（POMS）并进行了 30 秒的 Wingtate 测试，分别在 08:00、14:00 和 20:00 进行。主要的表现衡量指标，Wingtate 测试中的做功，随着时间的推移而增加（16.4 ± 4.8 kJ < 17.0 ± 5.0 kJ < 17.6 ± 5.2 kJ；< 0.01）。对于 M 型，从早上到下午的个人表现变化与精力 POMS 得分的个体变化相关（ = 0.81；< 0.03），而从下午到晚上的表现变化与疲劳的个体变化相关（ = - 0.85；< 0.02）。对于 E 型，则相反，因为从早上到下午的表现变化与疲劳的个体变化相关（ = - 0.70；< 0.08），而从下午到晚上的表现变化与精力的个体变化相关（ = 0.78；< 0.04）。结果表明，时间对晨型/晚型的影响与情绪状态和骑行表现之间的关系有关。
