RESUMO:

The purpose of this paper was to investigate the effect of competitive games on a congested calendar on mucosal immunity in young soccer players. For the development of this research, an observational, descriptive, transversal study was conducted in a quantitative approach. Twelve young male soccer players from the same team (age: 16.6 ± 0.51 years, height: 175 ± 8cm, body mass: 65 ± 7.9kg), from the sub category 17, that played five competitive games (J1, J2, J3, J4 and J5) with about 24-hour breaks between games. For quantification of S-IgA, it was expressed as absolute concentration of IgA (S-IgAabs), rate of IgA secretion (S-IgAtaxa) and salivary flow (FS), as proposed by Fahlman and Engels (2005) and Koch et al. Al. (2007). For the competitive internal load, it was determined by the PSE of the session. The playing time of each participating athlete during the five games was recorded to determine the competitive internal load by the session PSE. The results are presented as mean and standard deviation. Normality of the dependent variables was verified acording the Shapiro Wilk test (p> 0.05). Student's test was used to analyze salivary IgA and salivary flow rate in the first and fifth games of the competition ANOVA compared the session's score and an internal load over the games, Bonferroni's post hoc was used to identify the differences between how measures. Cohen 's "d" was used to estimate the magnitudes of the differences (effect size - TE) among all as comparisons. The Spearman correlation coefficient was used to analyze the correlation between the monotony index and the competitive effort with the absolute SIgA. The PSE values of the session were different throughout the games F (4.44) = 6.302, p <0.001, η²: 0.36. As observed in our games 1, 2 and 3 compared to game 5 (p <0.05), as well as values of internal load, also deferred along the competition F (4.44) = 5.175, p = 0 , Δ: 0.32. The absolute salivary IgA concentrations and compartment decreased after a competition when compared to the competition time (absolute IgA t (11) = 0.05) was observed in our games 2, 4 and 5 compared to 3 (p <0.05). In contrast, salivary flow flow preload pre-sets for post-t (11) = 0.1010, p = 0.921, p = 0.01, and relative IgA (t (11) = 2.744, p = 0.04). ). An association between the values of the salivary IgA variation delta and a competitive load was found to have a high and significant correlation with one (r = 0.68: p <0.05). In addition, a high positive and significant correlation was found between the competitive effort and the absolute IgA variation delta (r = 0.67: p <0.05). The data demonstrate that competitions with competitive games in a congested calendar had impact on the immune system and perceptual responses of perceived        exertion.
