Overview

The goal of this clinical trial is to test the benefits of beat-accented music stimulation (BMS) for behavioral changes of physical activity (PA) in older adults with subjective memory complaints. Specific Aims are to determine (1) whether BMS beneficially influences PA behaviors and psychological responses to PA in older adults for 6 months, and (2) whether exercising with BMS differently influences physical and cognitive functioning as well as quality of life in older adults.To test the effects of BMS on PA, participants will be randomly assigned to an exercise intervention that either includes BMS or does not include BMS. Participants will attend a supervised group strength training (ST) (30 min/day) and and aerobic exercise (AE) (30-50 min/day) session for 3 days/week for the first 2 months, 1 day/week for the next 2 months (while encouraging participants to independently perform both AE and ST on other days), and independently for the final 2 months (always with a goal of performing >150min/week AE and 3 days/week of ST for 30 min/day).
