(HealthDay News) — Reductions in liver fat or visceral adipose tissue do not differ significantly with the dose or intensity of aerobic exercise, according to a study published in the Journal of Hepatology.
Shelley E. Keating, from the University of Sydney, and colleagues examined the efficacy of commonly prescribed exercise doses for reducing liver fat and visceral adipose tissue.
Forty-seven inactive and overweight/obese adults were randomly assigned to receive 8 weeks of low- to moderate-intensity, high-volume aerobic exercise (LO:HI); high-intensity, low-volume aerobic exercise (HI:LO); low- to moderate-intensity, low-volume aerobic exercise (LO:LO); or placebo.
The researchers observed a significant change in group × time interaction in liver fat, with reductions of 2.38% in HI:LO, 2.62% in LO:HI and 0.84% in LO:LO and an increase of 1.1% in placebo. There were significant reductions in visceral adipose tissue in the HI:LO, LO:HI, and LO:LO groups but not in placebo.
No significant differences were seen between the dose or intensity of the exercise regimen and the deceases in liver fat or visceral adipose tissue.
“All of the aerobic exercise regimens employed reduced liver fat and [visceral adipose tissue] by a small amount without clinically significant weight loss,” the researchers wrote.
