Abstract

Background: Intensive and acute exercise trainings may induce oxidative stress, but antioxidant supplements may attenuate its degenerative consequences. The aim of this research was to examine the effect of green tea supplementation on the oxidative stress indices after an intensive resistance training session.
Materials and Methods: 40 non-athletes (without regular physical activity) women were randomly divided into 4 equal (n=10) groups including green tea supplementation, green tea supplementation plus resistance training, resistance training, and control groups. After supplementation period (600 mg/day, 14 days), resistance training and green tea supplementation plus resistance training groups performed an intensive resistance training session at 75-85 % of one repetition maximum. The malondialdehyde and total thiol were measured as oxidative stress indices. Data were analyzed by using of repeated measure ANOVA and LSD tests at p<0.05.
Results: Results showed that after 14 days of green tea consumption, malondialdehyde significantly decreased in green tea supplementation (p=0.03) and green tea supplementation plus resistance training (p=0.01) groups, while total thiol increased significantly (p=0.01) in two green tea supplementation groups. However, an intensive resistance training session increased malondialdehyde (p=0.01) without any significantly changes in total thiol (p=0.42).
Conclusion: It seems that green tea supplementation can inhibit exercise-induced protein and lipid oxidation in non-athletes women via enhancement of antioxidant defense system of the body.
