The effect of a ۲ weeks Taurine supplementation on liver damage indices, URE and lactate following a simulated volleyball test in female volleyball players

intense physical activity alters liver enzymes, URE and lactate by increasing metabolism. Taurine, as an antioxidant supplement, can reduce these amounts. researches have shown that protein supplementation can be effective in strength training.The aim of this study was to investigate the effect of a ۲-week Taurine supplementation on the response of some liver damage indices such as aspartate transaminase (AST), alanine amino transferase (ALT), urea (URE) and blood lactate following a simulated volleyball test for female volleyball players.In a quasi-experimental research project, ۲۴ adolescent female volleyball players (age: ۱۸/۱۱/۶ years, body mass= ۶۵/۱۹/۷ Kg ) were purposefully selectee and randomly assigned to the group Taurine (n=۱۱) or placebo (n=۱۲). Both groups had ۳ sessions of regular volleyball training every week. Taurine group had consumed ۳ gr per day. Blood samples were prepared in four stages: baseline, a day after supplementation, immediately and ۲۴ hours after simulated volleyball test at the rate of ۵cc of the forearm vein of the right hand in a sitting position. The samples were then tested by its kits to determine the changes in AST, ALT, URE, lactate. ۲۴ analysis of variance and T-test were used at the significant level of = ۰/۰۵.The level of AST enzyme in the supplement group was significantly increased in the compare of the placebo group (p< ۰/۰۵). Other indicators Changes were not significantly different between groups (p>۰/۰۵).Results show that there were only a significant difference between groups in stage three in AST. Unexpectedly we had an increase in AST levels in Taurine group. Taurine, as metabolic mediator, increased protein utilization in the liver, but the increase in AST is normal and it doesn’t lead to a liver damage. Maybe the stress or the duration of the simulated test was not high enough to lead to the expected rate of damage or the dosage of Taurine should be more than we used.
