NCT00771108

Brief Summary

The purpose of this research is to provide a better understanding of how exercise (walking) affects non-alcoholic fatty liver disease (NAFLD) in overweight people. NAFLD, which is common in obese people, occurs when the liver has too much fat.

Outcome Measures

Primary Outcomes (1)

  • The effect of aerobic exercise on: Intrahepatic fat content

    3 years

Secondary Outcomes (4)

  • VLDL-triglyceride (TG) and VLDL-Apolipoprotein B (apoB) kinetics

    3 years

  • Insulin action in liver (suppression of glucose production), muscle (stimulation of glucose uptake), and adipose tissue (suppression of lipolysis).

    3 years

  • Plasma markers of inflammation

    3 years

  • Potential cellular mechanisms responsible for changes in insulin action and inflammation

    3 years

Study Arms (2)

control

NO INTERVENTION

Subjects will serve as controls, continuing current diet and activity levels. Subjects will get monthly weights by the investigator at the research center.

Exercise

EXPERIMENTAL

For 16 weeks subjects will exercise from 30-60 minutes five times a week.

Behavioral: exercise

Interventions

exerciseBEHAVIORAL
