The effects of eight weeks aerobic training, green tea supplementation and compound of them on serum liver enzymes and apolipoproteins in inactive overweight women

Introduction: Catechin compounds in green tea can prevent lipid peroxidation by chemical materials in the liver and kidneys. The aim of this study was to evaluated the effects of eight weeks aerobic training and green tea supplementation and combination of them on serum liver enzymes and apolipoproteins in inactive overweight women. Methods: In this quasi experimental study, 40 subjects with age range 35-50 years and BMI 25-27 kg/m2 were selected by convenience sampling. They were divided randomly into 4 equal groups: aerobic training, green tea, aerobic training + green tea and control groups. Aerobic training program included aerobic exercises 45-60 minutes at 65-75 maximum reserve heart rate, three sessions per week which lasted for 8 weeks. Green tea group 2 hours after each meal brewed 2 g green tea in 100 mil liter water and consumed. To make intra and between group’s comparison, paired sample t-test and one-way analysis of variance (ANOVA) along with the follow-up test of LSD were used to examine the mean differences between the groups. The significance level for the study was less than 0.05. Results: The amounts of weight and BMI in each of three group’s aerobic training, green tea, aerobic training + green tea were reduced significantly. The levels of APOA and APOB only in aerobic training groups were statistically significant. The amount of ALT in aerobic training and the combination group, and AST levels in green tea and aerobic training group had a significant variation. The average difference in weight, BMI, APOB and AST were statistically significant. Conclusion:Eight weeks of aerobic training, consumption of green tea and combination of them through the reduction of liver enzymes and some cardiovascular risk factors can reduce the inflammation and improve cardiovascular health.
