The effect of eight weeks interval aerobic exercise and consumption of green tea supplementation on oxidative stress indices of inactive young girls

Not having physical activity with a physiological function disorder and reducing the body's resistance to oxidative stress. The green tea supplement increases plasma antioxidant defense system during rest and during exercise. The purpose of this study was to determine the effect of eight weeks of periodic aerobic exercise and green tea supplementation on oxidative stress indices in young girls inactive. The present semi-experimental study was carried out in the form of a pre and post design test. The statistical population consisted of all inactive young girls in Sanandaj city. 30 volunteers were randomly selected and divided into three groups of 10, including Practice-supplements, Practice-placebo and supplement alone. The periodic aerobic exercise program increased over the course of eight weeks, triple periods/week. Primary blood samples were taken at baseline before the start of supplementation, and the second blood samples were taken 48 hrs following the end of the 8-week activity. The Total Antioxidant Capacity (TAC) and Malondialdehyde (MDA) were measured using ELISA kit. One-way analysis of variance (ANOVA) with Tukey's post hoc test and t-test with significant level of p≤0.05 were used. There was a significant difference in MDA between the three groups. With MDA, the practice-placebo group showed a significant difference with the supplement group. However, in the TAC index, no significant difference was observed between the three groups in the post-test phase. Based on the results of t-test, the MDA index decreased significantly in all three groups, but the TAC index decreased significantly in the supplementation group. Regular physical activity seems to work like a supplemental anti-oxidant supplement which in stressful conditions maintains and improves the health of the person and addition of green tea supplement doubles the effect.
