Sažetak
Introduction: In sports, there are present numerous injuries and overtraining of athletes. Because of that, it is essential to properly dose training, recognize fitness levels and provide them time for a full recovery. The aim of this study was to determine the potential role of calprotectin and other biochemical biomarkers for athletes' fitness monitoring. Materials and methods: In this retrospective study, the 20 professional male waterpolo players were included (median age was 21 years (minimum-maximum: 15-31 years). During one competitive season, the physical fitness tests and concentrations of calprotectin and cortisol from blood were determined in four time periods (September (I), December (II), February (III), and May (IV)). The maximum number of pull-ups test was performed in analyzing physical fitness. Friedman ANOVA test was used for statistical analysis, with P<0.05 as a significance level. Results: The tendency of decrease calprotectin concentration was observed (median values (interquartile range (IQR)): I – 2.92 μg/mL (2.52– 3.82), II – 2.35 μg/mL (1.26– 2.87), III – 2.26 μg/mL (1.66–3.24) and IV – 1.47 μg/mL (1.05–2.74) (P<0.05)). Cortisol values are highest in the middle of the season, during peak training level (median values (IQR): I–214 nmol/L (120–312), II– 385 nmol/L (208–468), III – 376 nmol/L (219–516) and IV – 351 nmol/L (219–416) (P<0.05)). Respondents had better physical fitness results at the beginning than at the end of the season. The number of maximum pull-ups until failure: median values (IQR): I – 11.00 (9.50– 14.50), II – 9.00 (7.50–12.50), III – 7.00 (5.50– 10.50), and IV – 6.00 (4.50 ; 8.50) (P<0.01). Conclusion: Our results show that professional athletes lead their bodies to overtraining during the season which is manifested by a decline in fitness indicators and changes in certain biochemical markers. Calprotectin, as a potential new marker of fitness monitoring, shows a proportional tendency to decline together with fitness indicators.
