Effects of an Acute Bout of Light-Intensity Walking on Sleep in Older Women With Sleep Impairment: A Randomized Controlled Trial.
Study Goal
The researchers aimed to determine whether a single session of light-intensity walking could improve sleep quality in older women with mild sleep impairment.
Results Summary
The study found that light-intensity walking modestly reduced sleep latency and improved sleep efficiency in older women with mild sleep impairment, though no significant differences were observed in other sleep parameters.
Population
Older women aged 55 years or older with mild sleep impairment.
Effective Dosage
50 minutes of treadmill walking (single session).
Duration
Single session.
Interactions
None mentioned.

STUDY OBJECTIVES: This study aimed to explore the effects of a single bout of light-intensity walking on sleep in older women with mild sleep impairment. METHODS: A total of 40 women aged 55 years or older with mild sleep impairment were randomized to either a treadmill walking session for 50 minutes or a quiet-rest control. All participants completed the study (mean age: 60.4 ± 4.7 years). Sleep quality was assessed by ActiGraph for 2 nights before (pretest) and 2 nights after exercise (posttest). A mixed-design analysis of variance was used with group as the between-subjects factor and time point as the within-subjects factor. RESULTS: No significant group difference in demographic variables, body mass index, physical and mental status, and eight sleep parameters were observed at baseline. Significant group-time interactions existed for sleep latency ( CONCLUSIONS: A single session of light-intensity walking led to a modest reduction in sleep latency and improvement of sleep efficiency in older women with mild sleep impairment.
