O efeito de carga de treinamento nas respostas imuno-hormonais e subjetivas no período competitivo de atletas de voleibol

Abstract

His dissertation aims to describe the effects of training loads on immunohhormon and subjective responses during the competitive period of volleyball, as well as to verify the relationship between physiological and subjective variables and the internal training load (ITC). CIT was recorded daily using the subjective effort perception (PSE) method of the session, and the recovery status was obtained through the Total Recovery Quality (TQR) scale. During the competitive period, comparisons were made between three microcycles of different moments. Participated in this study 14 professional volleyball athletes from the team of Juiz de Fora. Athletes responded to pre and post microcycles on the scale of Well Being Scale (QBE) to assess overall welfare status. Saliva was also collected pre and post microcycles for salivary dosing of cortisol, testosterone and immunoglobulin (IgA). In addition to the ANOVA tests with Bonferroni post hoc, Pearson correlation and effect size, statistical tests of normality and sphericity were performed. For these tests, SPSS software (v. 20.0) was used and significance level of p ≤ 0.05 was adopted. The results showed the following data: medium-high and high loads; Responses with high IgA variability with 465.36% variation between pre and post in the M3 microcycle; No significant difference in relation to testosterone; Values below reference, at all times, relative to cortisol; Cortisol, testosterone and IgA did not show any significant correlation with CIT and with subjective variables, whose results - TQR and QBE - were compatible with the training load, with a significant correlation of very large magnitude in post M3 and CIT ; Already in the M1 microcycle, presented a peculiar behavior; In QBE, also responded to the behavior of the training load after M1 and M3, except in M2; Did not present any significant correlation with ITC. It is concluded that the effects of CIT indicate that the polishing microcycle should be planned from 1 to 2 microcycles to promote satisfactory effect of testoterone, cortisol and IgA in the competitive period.
