Abstract

The aim of the present study was to investigate effects of a 12-week aerobic exercise training program and a gym-ball exercise training program on body composition, aspartate aminotransferase (AST), alanine aminotransferase (ALT), adipokines, and cardiovascular risk factors in obese children with nonalcoholic fatty liver disease. The subjects were separated into two groups, an aerobic exercise group (n=10), which practiced moderate aerobic exercise training for 12 weeks, and a gym-ball exercise group (n=13), which practiced resistance exercise training for 12 weeks. The results of the analyses are as follows: Weight, body mass index, and body fat were significantly lower (p<0.01, respectively), whereas the VO₂ max was higher in both groups (p<0.01). Fasting glucose, insulin and HOMA-IR levels were significantly decreased in the gym-ball exercise group (p<0.05), whereas adiponectin, AST, and ALT levels were significantly increased (p<0.05, p<0.001, p<0.001, respectively) in both groups after the 12-week exercise training program. In addition, our results showed that HOMA-IR, insulin, and concentrations of C-reactive protein (CRP) were significantly lower in both groups. They demonstrate that a 12-week program of regular aerobic exercise or gym-ball exercise yields beneficial effects such as an amelioration of cardiovascular risk factors, body indices, and liver function in obese children with nonalcoholic fatty liver disease.
