Study of Remote and In-Person Aerobic Exercise Training to Improve Heart Health in Adults Over 45

What this Trial Is About

Researchers are evaluating different remote and in-person aerobic exercise training methods for adults over 45 who are at risk for cardiovascular disease CVD but are not meeting recommended physical activity levels. This pilot study aims to compare how acceptable and effective 12 weeks of exercise training delivered via smart-device apps, live virtual classes, self-directed programs, and in-person supervised sessions are for improving physical activity, cardiovascular fitness, and CVD risk factors. Participants will be randomly assigned to one of four exercise approaches in-person supervised sessions three times per week at a facility with real-time heart rate monitoring live-streamed virtual classes led by a trainer with real-time feedback self-directed aerobic exercise with guidance and periodic trainer check-ins using the Map My Fitness app or training using the Myzone heart rate monitor and app, which provides automated feedback and motivational support three times per week. The exercise intensity and frequency vary slightly depending on the modality. During the study, participants will undergo cardiopulmonary exercise testing before and after the 12-week program to measure fitness changes. Researchers will track weekly moderate to vigorous physical activity minutes, cardiovascular fitness VO2peak, blood pressure, body mass index, body fat percentage, fasting glucose, and quality of life using the SF-36 survey. Participants will also answer questions about their experience and acceptance of the exercise programs. The study will last up to 13 weeks for each participant.
