Study of Muscle, Mobility and Aging (SOMMA) Jr

About SOMMA Jr

Do you ever wonder what happens to our muscles as we get older?

SOMMA (Study of Muscle, Mobility, and Aging) Jr, is a university research study that is taking place at two academic research centers at the University of Pittsburgh and Wake Forest Baptist Medical Center. The main purpose of SOMMA Jr is to understand how muscle changes as we get older. We hope that this research project will allow us to compare muscle characteristics in older and younger adults and understand why some people develop problems walking as they get older.
