- % Time in Stage 2 Sleep at 12 Months, Adjusted for Baseline [ Time Frame: baseline, 12 months ]Percent of total sleep time spent in Stage 2 sleep at 12 months after adjusting for baseline level of Stage 2 sleep (i.e., baseline value included as a covariate in regression models conducted).
- Sleep Disturbances [ Time Frame: 12 months ]
Self-reported sleep disturbance subscale on Pittsburgh Sleep Quality Index Subscale consists of 9 items scored on a range of 0 to 3, 0 indicating no disturbance and 3 indicating frequent disturbance.
All 9 items are summed, and the summary scores is captured by 1 of 4 categories ranging from 0 to 3, with 0 indicating less frequent disturbances and 3 indicating greater frequency of disturbances.
- Peak Exercise Oxygen Consumption [ Time Frame: 12 months ]Peak oxygen consumption measured during symptom limited treadmill exercise stress test

Sleep deprivation is a common problem among older adults. It is often at the root of increased mortality and some psychiatric disorders. Regular participation in a medium-intensity exercise regimen may help people sleep better. This study will assess the effectiveness of a regular exercise program on improving sleep in older adults with moderate difficulty sleeping.
Participants will be randomly assigned to one of two conditions. One group will partake in a moderate-intensity physical activity training regimen. The other group will act as a non-exercise attention-control comparison group. Each group will undergo its assigned treatment for 12 months. Sleep quantity and quality will be measured objectively using in-home polysomnography. Subjective sleep quality and health-related quality of life measures will be evaluated with questionnaires. All measurements will be performed at the beginning of the study, Month 6, and Month 12.
