The aim of the present study was to determine the effect of different nap opportunity durations on short-term maximal performance, attention, feelings, muscle soreness, fatigue, stress and sleep. Twenty physically active men (age: 21.1 ± 3.6 years, height: 176.4 ± 5.7 cm, body-mass: 72 ± 10.8 kg) performed the 5-jump and the digit-cancellation (i.e., attention) tests after four randomized nap opportunity conditions: no-nap opportunity (N0), 25 min of nap opportunity (N25), 35 min of nap opportunity (N35) and 45 min of nap opportunity (N45). Subjective measurement of feelings, muscle soreness, fatigue, stress and sleep were performed during each test session. Compared to N0, there was a significant improvement of the 5-jump performance during N35 (Δ = +3.5%, p < .01) and N45 (Δ = +3.7%, p < .01). Attention was also better after N45 compared to N0 (Δ = +7.5%, p < .05). Fatigue, sleep and stress scores were significantly lower after N25, N35 and N45 compared to N0 (p < .05). However, no-significant effect of naps durations on feelings and fatigue scores was observed. A nap opportunity has a beneficial effect on physical performance and attention with better results observed for naps ≥35 min.
本研究旨在确定不同小睡机会持续时间对短期最大性能、注意力、感觉、肌肉酸痛、疲劳、压力和睡眠的影响。20 名身体活跃的男性（年龄：21.1±3.6 岁，身高：176.4±5.7cm，体重：72±10.8kg）在四个随机小睡机会条件下完成了 5 次跳跃和数字取消（即注意力）测试：无小睡机会（N0）、25 分钟小睡机会（N25）、35 分钟小睡机会（N35）和 45 分钟小睡机会（N45）。在每次测试期间进行主观感觉、肌肉酸痛、疲劳、压力和睡眠测量。与 N0 相比，N35（Δ=+3.5%，p<.01）和 N45（Δ=+3.7%，p<.01）时 5 次跳跃性能有显著提高。与 N0 相比，N45 时注意力也更好（Δ=+7.5%，p<.05）。与 N0 相比，N25、N35 和 N45 时疲劳、睡眠和压力评分明显更低（p<.05）。然而，小睡持续时间对感觉和疲劳评分没有显著影响。小睡机会对身体表现和注意力有有益影响，持续时间≥35 分钟的小睡效果更好。
