O xidative stress and muscle cell damage biomarkers monitoring in male volleyball athletes during a competitive season . Brazilian Jou rnal of Biomotricity. v. 7, n. 4 , p. 208 - 218 , 2013. This study evaluated the oxidative stress markers in volleyball players along three distinct phas es of a championship to determine if they were able to reflect the different stress levels (phase 1: low intensity exercises; phase 2: increase in load of training and start of the championship; phase 3: decreases in sessions and load of training and the f inal phase of the championship). We measured the antioxidant status (catalase - CAT, glutathione reductase - GR activities and plasma total sulfhydryl groups - TSG concentration); the oxidant status (reactive carbonyl derivatives - RCD and thiobarbituric acid reac tive substances - TBARS concentrations); and assessed the muscular damage levels through plasma creatine kinase (CK) activity in blood samples of non - trained subjects (n = 9) and volleyball players (n = 9). We found at phase 2 a significant increase of plasm a RCD concentration and an evident tendency of increase in plasma CK activity. At this moment, the antioxidant enzyme activities decreased to the lowest levels. The decrease in overload during phase 3 induced a significant up - regulation of enzyme activitie s and an important decrease of RCD in comparison with phase 2. The biomarkers analyzed reflected the different degree of stress imposed during the championship and showed that the players presented the lowest oxidative stress level combined with the best p erformance parameters during the principal phase (phase 3) of the championship. 2013 artículo científico 1981-6324 https://www.redalyc.org/articulo.oa?id=93031520005 en http://www.redalyc.org/revista.oa?id=930 Brazilian Journal of Biomotricity application/pdf Universidade Iguaçu Brazilian Journal of Biomotricity (Brasil) Num.4 Vol.7 |
