NCT04987879

Brief Summary

There is no known cure or regulatory agency approved drug therapy for nonalcoholic fatty liver disease (NAFLD), the leading cause of liver disease worldwide, and its progressive type, NASH. This places increased importance on using exercise to treat NAFLD. While physical activity is recommended for all with NAFLD, how to best prescribe exercise as a specific treatment remains unknown, including what dose of exercise is most effective.

Study Arms (3)

Exercise Arm 1

EXPERIMENTAL

Aerobic exercise will be completed by walking, jogging or running or by using cardio equipment (e.g., recumbent bike). Each session will begin with a warm-up with walking and dynamic exercises. A 5-min walking cool down will end the session. The training dose for this arm is 750 MET-min/wk for 3-5 days per week, 22-45 minutes per session at a moderate to vigorous intensity. The exercise can be completed in person or virtually.

Behavioral: Exercise

Exercise Arm 2

EXPERIMENTAL

Aerobic exercise will be completed by walking, jogging or running or by using cardio equipment (e.g., recumbent bike). Each session will begin with a warm-up with walking and dynamic exercises. A 5-min walking cool down will end the session. The training dose for this arm is 1,000 MET-min/wk for 3-5 days per week, 30-60 minutes per session at a moderate to vigorous intensity. The exercise can be completed in person or virtually.

Behavioral: Exercise

Standard of Care

NO INTERVENTION

This group will receive best NASH clinical practices counseling at baseline and end-of-trial in accordance with NAFLD clinical practice guidelines and be reinforced by handouts from the American Liver Foundation.

Interventions

ExerciseBEHAVIORAL

Aerobic exercise can be completed by walking, jogging or running or by using cardio equipment (e.g., recumbent bike). Each session will begin with a warm-up with walking (30-40% target HR for 5-min) and dynamic exercises (knee-to-chest, 10-yd lateral shuffle, bent over twist, calf sweeps, leg swings). A 5-min walking cool down will end the session (30-40% target HR).
