Participants will be randomized into one of two different experimental groups: 1) Exercise group and 2) No exercise (control group). Subject participation in the study will involve a series of metabolic tests before and after participants undergo a 10% weight loss program (with or without exercise training depending on group randomization). After completing this weight loss portion of the study, participants will then be required to adhere to a high calorie diet program to regain half of the weight the participant lost - followed by the same series of metabolic tests.
Exercise is among the first line treatments for obesity and obesity-related diseases, yet it is shocking how little is known about how exercise works to improve health. Expanding the knowledge about novel exercise-induced adaptations in fat tissue of obese individuals and furthering the understanding about mechanisms underlying these adaptations could lead to innovative approaches for preventing and treating insulin resistance and obesity-related diseases. Overall, the researchers believe that exercise training modifies key processes in subcutaneous fat tissue that may contribute to an increa…
