Changes in fat and skeletal muscle with exercise training in obese adolescents: Comparison of whole‐body MRI and dual energy X‐ray absorptiometry

We examined skeletal muscle (SM) and fat distribution using whole-body MRI in response to aerobic (AE) versus resistance exercise (RE) training in obese adolescents and whether DXA provides similar estimates of fat and SM change as MRI.Thirty-nine obese boys (12-18 years) were randomly assigned to one of three 3-month interventions: AE (n = 14), RE (n = 14), or a control (n = 11).At baseline, MRI-measured total fat was significantly greater than...
