Introduction: The effect of green tea supplementation and resistance training on malondialdehyde (MDA) levels, total antioxidant capacity (TAC) and lipid profile is not well known. The present study investigated the effect of green tea supplementation with and without resistance training on the levels of MDA, TAC and lipid profiles of overweight men and women. Methodology: The statistical sample of this research was 35 men and women (age: 37.9±4.7, body mass index: 28.6±2.2) middle-aged volunteers and overweight, who were randomly divided into three exercise groups + Placebo, green tea and exercise + green tea were included. Resistance training was performed for 10 weeks, 3 sessions per week in 7 movements and with 70% intensity of one maximum repetition. The subjects of the green tea group consumed 2 tablets of 500 mg of green tea daily and after each meal. The exercise group + placebo, under the same conditions, consumed maltodextrin. 48 hours before and after the intervention, blood sampling was done under fasting conditions. Results: Triglyceride and HDL did not change significantly in any group (p<0.05). TAC and MDA levels increased (p=0.012) and decreased (p=0.003) only in the exercise + green tea group. Total cholesterol was reduced in all three groups of exercise + green tea (p=0.006), exercise + placebo (p=0.001) and green tea (p=0.020). LDL decreased only in the exercise + green tea group (p=0.009). Conclusion: 10-weeks consumption of green tea supplement along with resistance training has better effects than consumption of green tea alone on oxidative and anti-oxidant indices and also improving lipid profile of overweight people.
