The purpose of this observational study is to determine whether moderate-intensityexercises improve the quality of sleep for subjects with insomnia. The duration of thisobservational study was four weeks. For the first two weeks of the observational study,subjects served as their own control and completed a sleep log. At the beginning ofthe third week, subjects were randomly split into (1) Group One with moderate-intensityexercise or (2) Group Two with high-intensity exercise. Two-tailed t-tests displayedsignificant improvements in quality of sleep with the implementation of both moderateand high-intensity exercise. However, Group One participants were found to feelsignificantly more well-rested than Group Two. The moderate-intensity exercise groupshowed improvement in quality of sleep, the number of awakenings, and restfulness.In comparison, the high-intensity exercise group demonstrated improvement in thenumber of awakenings and daytime sleepiness; although, without reported improvementin sleep quality. There were variables in participants’ sleeping environments, includingchanges in sleep location, travel, sleep-inducing medication, alcohol use, anxiety,unanticipated noise disturbances, and use of electronic devices before bed that wasnot controlled for in this observational study.
