About

This is a research study about how short-term exercise intervention affects adolescents with a disease called non-alcoholic fatty liver disease (NAFLD).

Full description

The study investigators want to learn more about the effect of a type of exercise on non-alcoholic fatty liver disease (NAFLD), and on markers of health (for example, liver, heart, and overall health) and how the body uses energy in teenagers. The exercise we are studying is called high-intensity interval training, or HIIT. Some participants in this study will receive a 4-week exercise program, and the others will not.
