Changes in Body Composition Including Muscle With Anti-Obesity Medications, Both With and Without Exercise

Sponsor: University of Kansas Medical Center

Summary

The goal of this clinical trial is to learn whether adding either cardiovascular exercise or resistance exercise to pharmacotherapy treatment for obesity improves the retention of lean mass compared to pharmacotherapy alone in adults with overweight or obesity who are prescribed pharmacotherapy for obesity treatment by their personal physician. It will also provide information about whether either form of exercise added to pharmacotherapy for obesity treatment 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 total lean body mass between pharmacotherapy alone and either pharmacotherapy plus cardiovascular exercise or pharmacotherapy plus resistance exercise? * Is there a difference in the change in muscle mass between the intervention conditions (pharmacotherapy alone, pharmacotherapy plus cardiovascular exercise, pharmacotherapy plus resistance exercise)? * Is there a difference in the change in muscle quality between the intervention conditions (pharmacotherapy alone, pharmacotherapy plus cardiovascular exercise, pharmacotherapy plus resistance exercise)? * Is there a difference in the change in body weight between the intervention conditions (pharmacotherapy alone, pharmacotherapy plus cardiovascular exercise, pharmacotherapy plus resistance exercise)? * Is there a difference in the change in body composition (fat mass, fat mass distribution) between the intervention conditions (pharmacotherapy alone, pharmacotherapy plus cardiovascular exercise, pharmacotherapy plus resistance exercise)? * Is there a difference in the change in cardiorespiratory fitness between the intervention conditions (pharmacotherapy alone, pharmacotherapy plus cardiovascular exercise, pharmacotherapy plus resistance exercise)? * Is there a difference in the change in muscle strength between the intervention conditions (pharmacotherapy alone, pharmacotherapy plus cardiovascular exercise, pharmacotherapy plus resistance exercise)? * Is there a difference in the change in physical function between the intervention conditions (pharmacotherapy alone, pharmacotherapy plus cardiovascular exercise, pharmacotherapy plus resistance exercise)? * Is there a difference in the change in bone mineral density between the intervention conditions (pharmacotherapy alone, pharmacotherapy plus cardiovascular exercise, pharmacotherapy plus resistance exercise)? * Is there a difference in the change in bone biomarkers between the intervention conditions (pharmacotherapy alone, pharmacotherapy plus cardiovascular exercise, pharmacotherapy plus resistance exercise)? * Is there a difference in the change in resting blood pressure between the intervention conditions (pharmacotherapy alone, pharmacotherapy plus cardiovascular exercise, pharmacotherapy plus resistance exercise)? * Is there a difference in the change in energy intake between the intervention conditions (pharmacotherapy alone, pharmacotherapy plus cardiovascular exercise, pharmacotherapy plus resistance exercise)? * Is there a difference in the change in physical activity between the intervention conditions (pharmacotherapy alone, pharmacotherapy plus cardiovascular exercise, pharmacotherapy plus resistance exercise)? * Is there an effect of sex, race/ethnicity, age, menopausal status, obesity management medication type, or other demographic characteristics on the outcomes that are being measured. * What is the extent to which the retention of lean body mass or muscle mass mediates the effect of exercise on weight changes. Participants will: * Initiate and continue throughout the study period an eligible obesity management medication that is prescribed by their healthcare provider, and to report their adherence to this medication to the investigators. * Participant in this study for a period of 6-8 months to complete outcome assessments that occur at baseline and at the conclusion of 6 months of the intervention period, and monitoring visits that occur at weeks 3, 6, 9, 12, 15, 18, and 21. * If attend 3 supervised exercise sessions per week if assigned to either the cardiovascular exercise intervention or the resistance training intervention for a period of 24 weeks.
