Introduction: The endurance race is an important natural gesture for humanity for having contributed to their survival. The survival depended on hunting and gathering food, which required a prevalent pattern of physical activity probably practiced on a daily basis, which included prolonged exercise in the submaximal running form, interspersed with other high intensity. Studies aimed at assessing the effects of race on performance indicators have long been consolidated, while those related to the immune system have only begun to be investigated by science in the 1980s To investigate the effects of a periodic training protocol on performance determinants lasting 16 weeks on performance indicators: VO2max., LAn and EC, and on the circulating levels of IL-6 and IL-10 inflammatory mediators. Methodology: 23 runners resistance (endurance), male, divided into two groups: athletes-AG (N = 11), age (32.3±4 years age, VO2máx (ml∙kg-1∙min-1) 65, 6 ± 6.5) and recreational group-RG (N = 12), aged 32.1±6.4 years age, VO2máx (ml∙kg-1∙min-1) 46±4.7, were submitted to evaluations of performance indicators: underwent performance indicators of ratings: Maximum consumption of oxygen (VO2máx), anaerobic threshold (AT), and race economy (ER) and circulating inflammatory mediators: IL-6 and IL-10 before, during and after a training macrocycle lasting 4 months. Statistical Analysis: The variances normality and homogeneity were evaluated by Shapiro-Wilk and Levene tests, respectively. All data showed normal distribution and variance homogeneity, except interleukins, which were assessed by the McNemar absolute frequency test and Fischer's exact test for significance of changes (i.e., tests for two related samples). The results were expressed as mean (±) standard deviation. It was applied Student's t test for independent samples for comparison the sample characterization variables. The repeated measures interaction between and within groups were compared using ANOVA. Comparison of interleukins, without normal distribution (p <0.05) was Comparison of interleukins, the normal distribution without (p <0.05), which were evaluated by absolute frequency McNemar test and Fisher's exact test for the significance of changes (test for two related samples). The procedures were performed with the software Statistical Package aid for Social Sciences for Windows 21.0 (SPSS 21.0) and Graph Pad Prism 6. The significance level was set at 5% (p<0.05). It was observed significant improvements in the comparison between the pre- (T1) and after (T3), in both groups, the VO2máx. (P=0.001) and (p=0.003), respectively). IL-6 levels were lower the detection values at three different times (T1, T2 and T3), in both groups, while IL-10 levels showed a significant increase in the frequency, when compared to pre- (T1) with prost time (T3) (p=0.038) among all subjects. Conclusion: There was a significant improvement in VO2max and an increase in the absolute frequency of IL-10, when pre (T1) and post macrocycle (T3) were compared. |
