| Popis | Salivary lysozyme (SLys), an antimicrobial protein of nonimmunoglobulin nature, and salivary immunoglobulin A (sIgA), the principal antibody in saliva, cooperates in ensuring of oral tissue and airways health. Besides their antibacterial activity SLys and sIgA have been proven as parameters changing in response to stressful stimuli of different origin (e. g., physical or mental strain), therefore might be useful for assessing optimal sports load/recovery ratio. There is only one study investigating SLys (and numerous studies regarding sIgA) after long-term intense exercise in adolescent athletes, however no study has been conducted to deal with relationship (correlation) between SLys and sIgA in relation to the individual periods of adolescent athletes´ annual training cycle (I-just after the pre-seasonal rest, II-immediately after the training period and III-just after the competition period). Therefore -based on previous research- in this pilot study in adolescent male gymnasts of national/international level (n=11, age: 15.0±1.6), we aimed to prove/disprove following hypotheses: 1) SLys and sIgA values could correlate positively as examined for individual periods of the annual training cycle. 2) more strenuous long-term physical exercise could be connected to higher decrease in SLys and sIgA. Obtained results have shown that SLys levels were found to have no significant relationship with sIgA for any of individual periods of the annual training cycle. SLys levels at period II (just after the training period) are significantly lower (p < 0.05) compared to both period I and period III, whilst sIgA levels does not differ significantly among the individual periods of the annual training cycle. |
