Resistance Exercise and Muscle Protein Synthesis in Obese Adults

Completed · Not applicable

Conditions studied: Obesity

In brief

Obesity has numerous comorbidities that are associated with exceedingly high healthcare costs. In addition to well- characterized impairments in lipid and glucose metabolism, obesity is associated with altered protein metabolism. We have recently observed that obese individuals are essentially nonresponsive to protein ingestion with respect to myofibrillar protein synthesis. This suggests that skeletal muscle remodeling in obese individuals is impaired possibly contributing to a poor metabolic quality of muscle. Resistance exercise is known to strongly augment muscle protein synthesis in response to protein ingestion. The purpose of this research is to determine the muscle protein synthetic response during post-exercise recovery in obese individuals. Using stable isotope methodology, we will determine the postprandial muscle protein synthetic response in 14 male and female obese adults (Age: 20-45, BMI: 30-39.9 kg/m2) immediately after an acute bout of resistance exercise. Participants will be sedentary (\< 60 min exercise/ week) and weight stable for a minimum of 6 months. During the testing blood and muscle samples will be collected. In addition participants will be asked to perform moderate intensity resistance exercise. Completion of the proposed research will identify the role of resistance exercise in the maintenance of skeletal muscle tissue after the consumption of a protein-dense meal in obese people.
