Background: The aim of this research was to examine the effects of green tea supplementation on plasma total antioxidant capacity (TAC) and lipid peroxidation in young women after a resistance training session. Methods: Forty young women were randomly divided into four equal groups of green tea supplementation, green tea supplementation and resistance training, resistance training, and control. After supplementation period (14 days, 600 ml/day), subjects performed an intensive resistance training session with 85% of one repetition maximum (1RM). Blood samples were taken at baseline, at the end of supplementation period, and after the exercise protocol. TAC and malondialdehyde (MDA) were measured using Ferric Reducing Antioxidant Power (FRAP) assay and thiobarbituric acid (TBA), respectively. Findings: After 14 days, the TAC significantly increased (P < 0.001) and MDA significantly decreased (P < 0.01) in the green tea supplementation and resistance training group. However, intensive resistance training decreased TAC (P < 0.04) and increased MDA (P < 0.01) significantly in the resistance training group. Conclusion: Our results suggested that green tea supplementation will be useful for improving TAC and thereby inhibiting exercise-induced lipid peroxidation after intensive resistance training.
