Identification of Novel Skeletal Muscle-derived Factors That Promote Lipid Oxidation (Columbus)

Running, not enrolling · Not applicable

Conditions studied: Obesity, Disorder of Lipid Storage and Metabolism, Lipid Metabolism Disorders, Metabolic Disorder

In brief

The purpose of this study is to collect data to help researchers identify factors, such as certain proteins or genetic codes, that are secreted from muscle that are associated with the beneficial effects of exercise.
