Inadequate sleep is associated with cardiometabolic risk and adiposity. Exercise has been suggested as an efficient strategy to improve sleep; however, the effects of different types of exercise on sleep in individuals with overweight and obesity are not well understood. We examined effects of active commuting and leisure-time exercise on sleep in individuals with overweight or obesity. 130 physically inactive adults (20-45 years) with overweight or class 1 obesity (body mass index: 25-35 kg/m) were randomized to 6 months of habitual lifestyle (CON, = 18), active commuting by bike (BIKE, = 35), or leisure-time exercise of moderate intensity (MOD, 50% VOpeak-reserve, = 39) or vigorous intensity (VIG, 70% VOpeak-reserve, = 38), 5 days/week. Sleep was assessed from 7-day/night accelerometry and questionnaires at baseline, 3 months, and 6 months. 92 participants were included in a analysis. At 3 months, sleep duration was longer in VIG (29 min/night [3; 55] (mean [95% CI]), =0.03) but not in BIKE and MOD ( ≥ 0.11) compared with CON and was not different between groups at 6 months ( ≥ 0.36 vs. CON). At 6 months, sleep duration variability was lower in MOD (-31% [-50; -3], =0.03) and numerically lower in VIG (-28% [-49; 1], =0.06) relative to CON but was unchanged in BIKE (=0.17 vs. CON). The effects were, however, primarily attributable to shorter and more irregular sleep in CON over time. Our findings suggest that effects of exercise on sleep in individuals with overweight and obesity may be restricted to leisure-time exercise with a short-term effect on sleep duration after vigorous intensity exercise (3 months) but a more regular sleep pattern after 6 months of moderate and vigorous intensity exercise compared with physically inactive controls. This trial was registered at clinicaltrials.gov with ID NCT01962259.
睡眠不足与心血管代谢风险和肥胖有关。运动被认为是改善睡眠的有效策略；然而，不同类型的运动对超重和肥胖个体睡眠的影响尚未得到充分了解。我们研究了主动通勤和休闲运动对超重或肥胖个体睡眠的影响。130名身体不活跃的成年人（20 - 45岁），超重或患有1级肥胖（体重指数：25 - 35kg/m²），被随机分为6个月的习惯性生活方式组（CON，n = 18）、骑自行车主动通勤组（BIKE，n = 35）、中等强度休闲运动组（MOD，50% VO₂峰值储备，n = 39）或高强度休闲运动组（VIG，70% VO₂峰值储备，n = 38），每周运动5天。在基线、3个月和6个月时，通过7天/夜的加速度计和问卷对睡眠进行评估。92名参与者纳入分析。在3个月时，与CON组相比，VIG组的睡眠时间更长（每晚29分钟[3；55]（均值[95%置信区间]），P = 0.03），而BIKE组和MOD组则不然（P≥0.11），6个月时各组之间无差异（与CON组相比P≥0.36）。在6个月时，相对于CON组，MOD组的睡眠时间变异性较低（-31%[-50；-3]，P = 0.03），VIG组在数值上较低（-28%[-49；1]，P = 0.06），而BIKE组则无变化（与CON组相比P = 0.17）。然而，这些影响主要归因于CON组随着时间推移睡眠更短且更不规律。我们的研究结果表明，运动对超重和肥胖个体睡眠的影响可能仅限于休闲运动，高强度运动（3个月）对睡眠时间有短期影响，但与身体不活跃的对照组相比，中等强度和高强度运动6个月后睡眠模式更规律。该试验已在clinicaltrials.gov注册，注册号为NCT01962259。
