Abstract

Background and Objective: We aimed to compare the differences in the subjective and objective sleep quality, and quality of life (QOL) according to the duration and timing of exercise in community-dwelling adults, and to compare these between the exercise group (EG) and non-exercise group (non-EG) in insomnia patients.
Methods: We recruited 223 volunteers (EG: n = 119, age: 60.8 ± 12.8 years; non-EG: n = 104, age 61.6 ± 13.3 years), who visited to 3 Public Health Centers in a rural area of South Korea. The Pittsburgh Sleep Quality Index (PSQI), Korean version of Epworth Sleepiness Scale (KESS), and Short Form-12 Health Survey Questionnaire (SF-12) were administered for each subject. Actigraphy (Actiwatch-2, Philips Respironics Co.) recording was done for 7 days at home, and we included the data of 183 subjects in our analysis. We compared the scores of questionnaires and objective sleep parameters according to the duration and timing of exercise, and compared these between the EG and non-EG in insomnia patients.
Results: Physical component summary (PCS) scores in SF-12 were higher in the EG for more than 60 minutes per day. In the subjects with outdoor exercise, the afternoon EG had lower PSQI scores and higher KESS scores. In insomnia patients, PCS scores in the EG was higher than those of the non-EG.
Conclusions: Community-dwelling adults who exercised for more than one hour showed higher physical QOL compared to those for less than one hour. Insomnia patients who exercised also showed higher physical QOL. In outdoor exercise, afternoon exercise would be beneficial for subjective sleep quality than morning exercise.
