The association of physical activity and fitness with sleep still remains unclear since there is a lack of studies in this field of research using objective measurements of these variables. This study aimed to investigate the association of objectively-measured sedentariness, physical activity levels, and physical fitness with sleep quantity and quality in sedentary middle-aged adults. A total of 74 volunteers (52.7% women; aged 53.7 ± 5.1) were recruited for the present study. Cardiorespiratory fitness was measured through a maximal treadmill test, and muscular strength by extension and flexion peak torque, and by the hand grip test. Physical activity and objective sleep parameters were determined through accelerometry, and subjective sleep by the Pittsburgh Sleep Quality Index (PSQI). Reduced levels of sedentariness, greater VO, and greater muscular strength were positively related to improved objective sleep quantity and quality (all P ≤ 0.05). Furthermore, higher levels of overall physical activity, VO, and muscular strength were related to better subjective sleep quantity and quality (all P ≤ 0.05). Reduced sedentariness and increased physical activity and fitness may be a potential prevention and/or treatment pathway to reduce sleep disturbances and, in general, to improve patients physical and psychological health for a successful aging process.
由于缺乏使用这些变量的客观测量值的研究，体力活动和健康与睡眠之间的关联仍然不清楚。本研究旨在调查久坐的中年成年人中客观测量的久坐行为、体力活动水平和身体健康与睡眠数量和质量的关联。本研究共招募了 74 名志愿者（52.7%为女性；年龄 53.7±5.1）。心肺健康通过最大跑步机测试进行测量，肌肉力量通过伸展和弯曲峰值扭矩以及握力测试进行测量。通过加速度计确定体力活动和客观睡眠参数，通过匹兹堡睡眠质量指数（PSQI）确定主观睡眠。减少久坐时间、更大的 VO₂ 和更大的肌肉力量与客观睡眠数量和质量的改善呈正相关（均 P≤0.05）。此外，更高水平的总体体力活动、VO₂ 和肌肉力量与更好的主观睡眠数量和质量相关（均 P≤0.05）。减少久坐时间以及增加体力活动和身体健康可能是减少睡眠障碍的一种潜在预防和/或治疗途径，总体上可以改善患者的身心健康，以实现成功的老龄化过程。
