Relative Sarcopenia and Cardiometabolic Risk in Young Adults With Obesity

Relative Sarcopenia and Cardiometabolic Risk in Young Adults With Obesity

The goal of this research study is to learn more about the hormones that muscles make during exercise, and if those hormones are associated with type 2 diabetes risk in adults who are overweight or obese. Participants will undergo exercise testing on an upright bicycle, with blood samples taken for muscle hormones before and after exercise. The hypothesis is that adults with overweight/obesity and insulin resistance will have an impaired muscle hormone profile in response to exercise compared to adults with overweight/obesity who are not insulin resistant.

Inclusion Criteria:

• Previously enrolled in protocol 2004P000013 or protocol 2012P002276, which had overweight or obesity as inclusion criteria
• Ability to walk up 3 flights of stairs and 3 city blocks (to ensure ability to complete exercise testing)

Exclusion Criteria:

• Unstable heart or lung disease
• Exercise >150 minutes/week
