Muscle Quantity and Quality, With and Without Exercise, Combined With Anti-Obesity Medications
The goal of this clinical trial is to learn about changes in body composition related to obesity medication use, and whether aerobic or resistance exercise training will impact these body composition changes. It will also provide information about whether aerobic or resistance exercise training has additional benefits on other health and fitness measurements. The main questions it aims to answer are: * Is there a difference in the change in body composition (fat mass, lean mass, muscle mass, and bone content) between the standard medical care and the exercise conditions (aerobic training and resistance training)? * Is there a difference in the change in body weight and BMI between the standard medical care and the exercise conditions (aerobic training and resistance training)? * Is there a difference in the change in cardiorespiratory fitness between the standard medical care and the exercise conditions (aerobic training and resistance training)? * Is there a difference in how much physical activity is completed between the standard medical care and the exercise conditions (aerobic training and resistance training)? * Is there a difference in the change in physical function between the standard medical care and the exercise conditions (aerobic training and resistance training)? * Is there a difference in the change in muscle strength between the standard medical care and the exercise conditions (aerobic training and resistance training)? * Is there a difference in the change in resting blood pressure between the standard medical care and the exercise conditions (aerobic training and resistance training)? * Is there a difference in the change in food intake between the standard medical care and the exercise conditions (aerobic training and resistance training)? * Is there a difference in the change in health-related quality of life between the standard medical care and the exercise conditions (aerobic training and resistance training)? Participants will: * Participate in an intervention for a period of 6 months that involves being assigned to a no exercise/standard medical care condition, or a supervised exercise condition (aerobic training or resistance training). * Visit the clinical before starting the study and at 6 months to complete study measurements of their body composition and other measurements to monitor their progress. * Complete a brief monitoring session at weeks 6, 12, and 18 across the 6 months. * Complete supervised exercise sessions at the research center 3x per week for 6 months (Participants in the exercise groups only: aerobic training or resistance training).
• Both males and females of all race/ethnic groups are eligible for participation in this study.
• Age: Randomized Study: Adults that are 18 to \<60 years of age. Observational Study: Adults that are \>60 years of age.
• Newly prescribed AOM (semaglutide, tirzepatide) for the treatment of obesity, approval for treatment (pharmacy, insurance, etc.), and the participant agreeing to start this treatment and continue treatment for at least 6 months (the participant will be recruited prior to this medication being initiated).
• Body mass index (BMI) of \>27.0 kg/m2 with at least one weight-related complication (hypertension, dyslipidemia, obstructive sleep apnea, or cardiovascular disease) provided it this does not compromise the ability to safely complete the screening or outcome measures or to engage in the prescribed exercise interventions), or \>30 kg/m2 without weight-related complications. Enrollment will not be limited based on an upper BMI level provided that the participant meets the other eligibility requirements. However, weight or size limits of the dual-energy x-ray absorptiometry (DXA) system that is used to assess body composition must not be exceeded.
• Ability to provide informed consent prior to participation in this study.
• Clearance from the study physician for meeting all eligibility criteria for this study.
