Introduction: Green tea as a rich source of antioxidant compounds, anti-inflammatory and anti-cancer one, has been under so much attention nowadays. The aim of this study is to investigate the effects of an eight-week aerobic exercises and the consumption of green tea as a supplement, and the effects of the compound of them on insulin resistance markers, liver enzymes and cardiovascular risk factors in overweight women.

Methods: In this clinical trial study, 40 volunteer subjects took part in the following research based on the agreement after signing a consent form. They were divided into four equal groups: green tea (T), aerobic training (A), aerobic training+green tea (A+T) and control groups (C). T group (3 times per day and after 2 hours of each meals, brewed 2 g green tea in 100 mil liter water and consumption).A group, participate in aerobic training included eight weeks (3 sessions per week, 45-60 minutes). Moreover, T+A group both actions were done with each other. To make intra and between groups comparison, paired sample t-test and one-way analysis of variance was used.

Results: The levels of APOA and APOB had a significant increase and decrease only in A group respectively compared with the period before and after training. Alanine aminotransferase (ALT) (p=0.001) had a significant variation in A and A+T group, and aspartate aminotransferase (AST) (p=0.001) levels in T and A group. Insulin and insulin resistance had statistically a significant decrease (p=0.001) in A and A+T group.

Conclusion: The combination of the eight-week aerobic exercises with the consumption of green tea has lead to reduce the insulin resistance markers, liver enzymes, and these factors can affect the reduction of the inflammation and improvement of  heart and vessels.
