Effect of 8 weeks aerobic exercise and vitamin C on liver transaminases activities in obese 8-11 years girls

Liver diseases accompanied with growing of obesity in children. This study was done to evaluate the effect of aerobic exercise and vitamin C intake on liver transaminases activities in 8-11 years obese girls.
In this quasi-experimental study, 28 obese girls were randomly divided into four equal groups including control, exercise, supplement (500 mg vitamin C tablet, dailly) and combined (500 mg vitamin C, daily plus exercise) groups. Aerobic exercise was consisted of exercise movements at 50% to 70% maximal heart rate and 3 sessions per week for 8 weeks. Fasting blood samples were collected before and 48 hour after the last intervention. Serum transaminases activities were measured by enzymatic colorimetric method.
8 weeks of aerobic exercise, vitamin C and the combined intervention were associated with a significant reduction in Alanine aminotransferase (ALT) and Aspartate aminotransferase (AST) activities (P It seems selected aerobic exercise and vitamin C intake may induce their protective effect in obese girls via improvement in liver function.
