Exercise training can reduce hepatic fat accumulation and cardiovascular risk among patients with non‐alcoholic fatty liver disease (NAFLD), but how long these benefits extend beyond the period of active intervention is unclear. Intrahepatic triglyceride (IHTG) content, measured by proton magnetic resonance spectroscopy, and metabolic risk factors among 220 obese people with NAFLD, who were randomly assigned to vigorous/moderate exercise, moderate exercise or no exercise (control), were assessed at 1 year after the 12‐month exercise intervention. IHTG content was significantly reduced in the 2 exercise groups compared with the control group over the 12‐month active intervention. It was significantly lower (by −2.39%) in the vigorous/moderate exercise group compared with the control group at the 1‐year follow‐up (95% confidence interval −4.72 to −0.05%; P = .045). Waist circumference and blood pressure remained significantly lower in the vigorous/moderate exercise group and the moderate exercise group compared with the control group at the 1‐year follow‐up. Visceral adipose fat remained significantly reduced, but with no differences among 3 groups. These findings suggest 12‐month exercise intervention induced reductions in hepatic fat accumulation, abdominal obesity and blood pressure for up to 1 year after the active intervention, with some attenuation of the benefits.
