Correlação entre aptidão aeróbia e biomarcador de estresse oxidativo em jogadores de futsal

The aim of the study was to verify the existence of correlation between level of aerobic fitness and the production of reactive oxygen species against an aerobic workload. The sample was composed of professional futsal players from the state of Sergipe. Variables related to maximal oxygen uptake (VO2max) and the production of reactive oxygen species were analyzed through the quantitative method of thiobarbituric acid reactive substances (TBARS). Data were analyzed using the Pearson correlation test and the student's t-test and significance level of 95% for the dependent variable. The results suggest that the production of reactive oxygen species and free radicals at rest is inversely proportional (r = -0.92) to the athlete's level of aerobic fitness and directly proportional (r = 0.56) during and / or after exercise. However, there was no significant difference (p> 0.05) between TBARS values before and after exercise.
