Abstract
The aim of this study was to investigate the effects of exercise characteristics and physical activity level on sleep quality in older adults. The study was completed on 349 older adults. Individuals, aged 60 years and older who scored 24 or greater on the mini mental test’s scores and who were not actively working were included. The short form of The International Physical Activity Questionnaire was used to determine the level of physical activity. The Pittsburgh Sleep Quality Index was used to evaluate sleep quality. There was a poor positive correlation between age and self-reported sleep quality in older women and older men (r = .205, p = .004, r = .317, p = .001). There was a negative correlation between physical activity and self-reported sleep quality in older women and older men (r = –.410, p = .001, r = –.488, p = .001). Living status was a factor significantly affecting sleep quality in older women (p = .016), whereas it was not significant for older men(p = .128). The presence of disease and regular exercise significantly affected sleep quality in older women and older men (p = .012, p = .003). However, no difference was found between exercise frequency, exercise duration, exercise time, exercise intensity and sleep quality in older adults (p > .05). According to these findings, regular exercise or physical activity at a minimal level may positively affect self-reported sleep quality in older adults. But exercise’s characteristic does not affect self-reported sleep quality differently.
