Distinct effects of low-intensity physical activity in the evening on sleep quality in older women: A comparison of exercise and housework

The effects of intensity, type, and time day physical activity on sleep are not well understood. An appropriate increase in core body temperature, due to during daytime, aids older adults. Our previous study showed that evening exercise has more positive quality adults when compared with morning exercise. However, who do form a large part the population. This aimed examine distinct low-intensity housework women. randomized crossover included 10 healthy women aged 65–79 years. participants engaged for 30 min, either aerobic (70 steps per minute), (at same intensity), or remained sedentary (control) 3 h before bedtime. Sleep was recorded polysomnographically, self-reported assessed next using Oguri-Shirakawa-Azumi inventory, Middle-Aged Aged version (OSA-MA) questionnaire. Compared control trial, temperature significantly elevated after each trial (0.5 ± 0.4 °C exercise, respectively). There significant difference latency (14.2 19.1, 9.9 15.6, 4.2 3.5 min control, housework, respectively; ANOVA P = 0.011) among trials. delta power density higher than trial. We observed an 53% 15% 1st hour as result respectively. total score OSA-MA (91.0 5.4, 88.1 6.9, 108.6 5.9 points Engaging improved polysomnographic quality. Although increased level lower
