This study assessed the effect of time of day (TOD) and listening to music during warm-up on cognitive and physical performances after partial sleep deprivation (PSD) and normal sleep nights (NSN). In a randomized order, twelve male physical education students [mean (SD) age 20.3 ± 2.0 y; BMI 22.90 ± 3.57 kg/m)] completed a 30-s Wingate test (., mean (MP) and peak powers (PP)), simple (SRT) and choice reaction times (CRT), a mental rotation test (MRT) and a selective attention test. Measurements were performed at 07:00 h and 17:00 h after a NSN and PSD with and without music, with an in-between recovery period of ≥72. Salivary cortisol was measured before and immediately after the Wingate test. Compared to NSN, the results showed that PSD decreased PP ( < .05, = 0.86) and MP ( < .01, = 0.86) in the afternoon. However, compared to NSN, listening to music during the warm up after PSD enhanced PP ( < .01, = 1.40) and MP ( < .05, = 0.82) in the morning and PP ( < .05, = 0.78) in the afternoon. Moreover, listening to music lowered post-exercise cortisol in the morning both after NSN ( < .05, = 0.79) and PSD ( < .05, = 0.11). After PSD, music reduced the negative mood states ( < .01, = 0.94), the SRT ( < .05, = 0.79) and the CRT ( < .05, = 0.49) in the afternoon. These findings suggest that listening to music during warm-up (i) enhances cognitive and short-term all out performances after NSN and PSD and (ii) partially counteracts sleep-loss-induced degradation of physical and cognitive performances at both TODs.
本研究评估了日间时间(TOD)和热身时听音乐对部分睡眠剥夺(PSD)和正常睡眠(NSN)后认知和身体表现的影响。12 名男性体育教育学生(平均(SD)年龄 20.3 ± 2.0 岁;BMI 22.90 ± 3.57 kg/m)以随机顺序完成了 30 秒的 Wingate 测试(平均(MP)和峰值功率(PP))、简单(SRT)和选择反应时间(CRT)、心理旋转测试(MRT)和选择性注意测试。在 NSN 和 PSD 后,分别于 07:00 和 17:00 进行测量,中间有≥72 小时的恢复期。在 Wingate 测试前后测量唾液皮质醇。与 NSN 相比,结果表明 PSD 下午降低了 PP(<0.05,=0.86)和 MP(<0.01,=0.86)。然而,与 NSN 相比,PSD 后热身时听音乐增强了上午的 PP(<0.01,=1.40)和 MP(<0.05,=0.82)以及下午的 PP(<0.05,=0.78)。此外,听音乐降低了 NSN(<0.05,=0.79)和 PSD(<0.05,=0.11)后运动后的皮质醇水平。PSD 后,音乐降低了下午的负面情绪状态(<0.01,=0.94)、SRT(<0.05,=0.79)和 CRT(<0.05,=0.49)。这些发现表明,热身时听音乐(i)增强了 NSN 和 PSD 后认知和短期全力表现,(ii)部分抵消了 TOD 下睡眠剥夺引起的身体和认知表现的下降。
