Objectives: To compare the effects of self-selected and predetermined intensity on sleep quality and duration, daytime sleepiness, and sleep efficiency of adolescents with obesity after 12 weeks of aerobic training.
Material and methods: Thirty-seven adolescents (12 girls), 13-18 years old, with obesity (BMI = 95th) were randomized into a predetermined intensity group (PIG), exercise intensity around 60-70% of heart rate reserve; or self-selected intensity group (SIG), the adolescents chose the speed/intensity at the beginning of each session and were able to change it every 5 minutes. The Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS) were used to assess sleep outcomes.
Results: No differences were observed for PSQI [0.00 ± 2.00 vs 1.38 ± 2.7; p=0.195; d=0.60 (moderate effect)], sleep duration [-0.95 ± 1.2 vs -0.35 ± 1.6; p=0.358; d=0.41 (small effect)], ESS [(2.10 ± 3.9 vs 1.15 ± 4.5; p=0.195; d=0.23 (small effect)], and sleep efficiency [(81.5 ± 24.0 vs 79.4 ± 17.0; p=0.8.14; d=0.10 (trivial effect)] for the PIG and SIG groups, respectively.
Conclusion: Aerobic training at a self- selected or predetermined intensity does not modulate sleep quality, sleep duration and efficiency, and daytime sleepiness, independent of intensity.
目的比较自我选择强度和预定强度对肥胖青少年进行 12 周有氧训练后的睡眠质量和持续时间、白天嗜睡和睡眠效率的影响：37名13-18岁的肥胖青少年（12名女生）（体重指数=95）被随机分为预定强度组（PIG）和自选强度组（SIG），预定强度组的运动强度约为心率储备的60-70%；自选强度组的运动强度为每节课开始时的速度/强度，青少年可以每5分钟改变一次。匹兹堡睡眠质量指数（PSQI）和埃普沃斯嗜睡量表（ESS）用于评估睡眠结果：结果：匹兹堡睡眠质量指数[0.00 ± 2.00 vs 1.38 ± 2.7; p=0.195; d=0.60（中等效应）]、睡眠持续时间[-0.95 ± 1.2 vs -0.35 ± 1.6; p=0.358; d=0.41（小效应）]、ESS[（2.10±3.9 vs 1.15±4.5；p=0.195；d=0.23（小效应）]，PIG组和SIG组的睡眠效率[（81.5±24.0 vs 79.4±17.0；p=0.8.14；d=0.10（微小效应）]分别为-0.95±1.2 vs -0.35±1.6；p=0.358；d=0.41（小效应）]：结论：自选或预定强度的有氧训练不会调节睡眠质量、睡眠时间和效率以及白天嗜睡，与强度无关。
