Does subjective sleep quality improve by a walking intervention? A real-world study in a Japanese workplace.
Study Goal
The researchers aimed to evaluate the impact of a 4-week walking intervention on subjective sleep quality in healthy workers with and without exercise habits.
Results Summary
The walking intervention improved overall sleep quality, including sleep latency, sleep duration, and perceived sleep quality, with more pronounced benefits in participants without prior exercise habits.
Population
490 healthy workers (214 with exercise habits, 276 without).
Effective Dosage
10,000 steps daily
Duration
4 weeks
Interactions
None mentioned

OBJECTIVES: The purpose of this study was to evaluate the impact of a 4-week walking intervention on subjective sleep quality. DESIGN: A prospective open-label study. PARTICIPANTS: A total of 490 healthy workers were included in the study. The 490 participants were divided into a group of 214 participants with exercise habits (exercising group, EG) and a group of 276 participants without exercise habits (non-EG). INTERVENTIONS: A walking intervention with a target of walking 10 000 steps daily for 4 weeks. OUTCOME MEASURES: The Pittsburgh Sleep Quality Index (PSQI) questionnaire was administered twice (before the start and after the end of the study). RESULTS: Overall, the walking intervention improved the participants' PSQI global score, sleep latency (minutes), sleep duration (hours), perceived sleep quality factor and daily disturbance factor. Among the EG participants, the walking intervention significantly improved the PSQI global score and perceived sleep quality. Among the non-EG participants, the walking intervention significantly improved the PSQI global score, sleep latency, sleep duration and perceived sleep quality. CONCLUSIONS: A walking intervention might reduce the sleep latency and increase total sleep duration in working persons without exercise habits.
