Abstract :
This study aimed to determine the effects of 4 weeks of vitamin C supplementation on total antioxidant capacity and serum lactate
of women active after eccentric exercise. Twenty active and healthy female volunteers (231.4 years, the percentage of fat 21.49
1.62 and the maximum oxygen consumption of 45.26 2.18 mL/kg. min) were divided into 2 random groups of complementary
homogenized vitamin C (1000mgdaily) and placebo (lactose 1000 mg). After 4 weeks of supplementation, all subjects participated
in an aerobic exercise on a treadmill at 80% of maximal oxygen consumption (negative slope of 5 degrees) for a total of 45 minutes.
Initial blood sample were taken at baseline before starting supplementation, the 2nd blood sample was taken after completing the
supplementation, and the 3rd samplewas taken after the sports convention. The normal data was examined using repeated analysis
of variance, Bonferroni and independent t-test at meaningful level of 5% by SPSS version 23. The results showed that 4 weeks of acute
consumption of vitamin C, prior to exercise, significantly increased (P < 0.05) the total antioxidant capacity of baseline. However,
45 minutes of running with a negative slope significantly decreased the total antioxidant capacity. Taking vitamin C had no effect on
serumlactate of activewomen(P> 0.05). According to the findings of the study, it can be concluded that vitaminCsupplementation
can probably reduce adverse changes in oxidative stress damage indices of aerobic exercise in disabled women by increasing total
antioxidant capacity of the base serum.
