Abstract

Taurine plays a major role in cell physiology, including membrane stabilization, osmoregulation and cytoprotective effects, antioxidant and anti-inflammatory properties. Therefore, the purpose of this study was conducted to identify the effect of taurine supplementation on response of muscle damage and oxidative stress indices following a simulated volleyball test in girl volleyball players. Methods: Twenty-four girls volleyball athletes (with mean age of 18.1±1.6 years, height: 177±9.2 cm and weight: 65.2±9.8 kg) in a randomized, quasi-experimental, double-blind design, were divided in two homogeneous supplement and placebo groups received 3 capsules containing 1g taurine or dextrose. After 14-days the supplementation, all subjects were participated in one session a simulated volleyball test. Blood samples were collected at four phases; baseline, after supplementation period, immediately and 24-hour after the test, were determined for changes in serum of muscle damage (CK and LDH) and oxidative stress (MDA and TAC) indices. Data were analyzed by repeated measure ANOVA and bonferroni post-hoc test at less than 0.05 α≤0.05. Results: The results show that the serum level of CK decreased significantly in the supplement group compared to the placebo group (P=0.012). On the other hand, one session a simulated training caused a significant decrease in TAC (P=0.02) and a significant increase in MDA (P=0.013). While, no significant difference was observed in any of the oxidative stress (TAC and MDA) and muscle damage (LDH) indices between the groups immediately after performing the activity (P≥0.05). Conclusions: Based on the present findings short-term supplementation of taurine may have an effect in reducing muscle damage. However, taurine consumption do not have the ability increased basal antioxidant capacity and also can not decrease the undesirable alterations of serum oxidative stress induced one-session of simulated volleyball test in female volleyball players.
