Brown Adipose Tissue as a Therapeutic for the Metabolic and Cardiac Dysfunction With Senescence (BATSR)

Older sedentary participants will undergo 8 weeks of exercise training. The exercise program will be supervised by a certified exercise physiologist and will take place at the AdventHealth Translational Research Institute (TRI) exercise training facility. Exercise compliance will be monitored for exercise training 4 days per week (32 total sessions). Aerobic training will be 30 minutes of brisk walking, jogging, cycle ergometry. Walking will be the primary mode of aerobic exercise given its widespread popularity and ease of administration across a broad segment of the older adult population. Walking will be at a moderate intensity and determined based on Heart Rate (50-70% of Maximal Heart Rate from most recent VO2max) and rating of perceived exertion using Borg's scale (ranges from 6 to 20).
