Abstract
Introduction: 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.
