Summary

This proposal will evaluate two brain health measures, cerebrovascular perfusion and cerebrovascular reactivity (CVR), before and after a proven, interval-based, aerobic exercise intervention in older Veterans. The hypothesis is that the 12-week aerobic exercise intervention (Spin) will increase perfusion and improve CVR in brain regions susceptible to age-related decline. This information will inform the impact of exercise on cerebrovascular health which is known to be negatively impacted in aging and implicated in the development of neurodegenerative disease. This information will also aid the investigators' continued efforts of clinical implementation of evidence-based exercise interventions in the local Atlanta VA and surround region.

Spin

The intervention will take place three times a week for 12 weeks and will be led by a qualified instructor (an Exercise Physiologist with five years of experience conducting the intervention). The duration of each session will be increased by 1-2 minutes to a maximum time of 45 minutes per session based on the progression of the participants and the recommendation of the instructor. Because participants are initially sedentary and detrained, exercise intensity will begin at low levels (50% of maximal heart rate reserve, HRR) but will be increased by 5% every week (if deemed necessary by the instructor) to a maximum of 75% maximal HRR.
