Study Summary
It has been hypothesized that exercise may have a beneficial effect on sleep quality and insomnia severity in those who have insomnia symptoms as well as those who meet diagnostic criteria for insomnia disorder (e.g., Diagnostic and Statistical Manual 5th edition (DSM-5)). Yet, the studies that have tested this are extremely limited in number and even fewer explore any acute effects of exercise training on subjects who meet diagnostic criteria. Thus, the investigators propose to conduct a randomized parallel design to compare the effects of short-term moderate-intensity aerobic exercise on insomnia severity and measures of sleep in a sample of adults who meet diagnostic criteria for insomnia.
Primary Outcome
Mean SE derived from wrist-worn actigraphy (7 nights of data)
Interventions
- OTHER Quiet Rest
- BEHAVIORAL Outdoor Walking
