Effect of Ginkgo biloba L. on total antioxidant capacity and malondialdehyde after aerobic exercise in inactive women

This study was conducted to determine the effect of short-term Ginkgo biloba L. on total antioxidant capacity (TAC) and malondialdehyde (MDA) after an aerobic exercise in inactive women. In a quasi-experimental study, twenty-four non-athlete women were allocated into a supplement (120mg/day Ginkgo biloba for 21 days) and placebo groups (120mg/day dextrose for 21 days). All the subjects participated in aerobic exercise protocol with 75% VO2 max on the treadmill for 30 minutes in pre and after supplementation. Venous blood samples were collected to assess the capacity of the TAC and MDA in four phases; 1) at the baseline 2) immediately after exercise test 3) after supplementation and 4) after supplementation and the second exercise test. Dates were analyzed by repeated measure ANOVA and LSD post-hoc test at α≤0.05. The results showed that MDA concentration increased, but TAC decreased significantly after aerobic exercise (P
