The purpose of the study was to examine the effects of sport training on carbohydrate metabolic indices and adipokines concentrations in young male triathletes (n=10). Athletes performed the incremental running test in two periods of the training cycle: in the transitory and preparatory phases. In both analyzed terms, physical exercise was reflected by a significant increase in lactate (p≤0.01), insulin (p≤0.01), visfatin concentrations (p≤0.01, p<0.05, respectively) and only during transitory phase in glucose (p≤0.01) and resistin concentrations (p<0.05). Significant inter-period differences were noted in the pre-exercise insulin (p≤0.01) and also in pre- and post-exercise visfatin concentrations (p<0.05). Additionally, the differences (Δ) between post- and pre-exercise values of glucose (p<0.05) and visfatin (p≤0.01) significantly decreased in the preparatory phase comparing to the transitory phase. The inverse correlations between pre-exercise concentrations of visfatin and peak oxygen uptake (p<0.05) in the transitory phase and between post- and pre-exercise differences (Δ) of visfatin and lactate concentrations (p<0.05) in the preparatory phase were noted. During preparatory phase, pre-exercise visfatin concentrations inversely correlated with pre-exercise resistin, insulin and glucose levels (p<0.05). In conclusion, systematic training in elite triathletes modulates basal adipokine concentrations only to a small extent, however, influences on these molecules response on the acute exercise.
