Carnitine metabolic features in young athletes
Abstract
Objective: to reveal differences in the carnitine metabolism of children going in for various sports. The peripheral blood levels of free (FC) and bound carnitine (BC) were studied; a BC/FC ratio was calculated using liquid chromatography-electrospray ionizationtandem mass spectrometry in 121 children, including 46 ice-hockey players, 48 swimmers, and 27 healthy schoolchildren. The study established that the levels of FC in the group of ice-hockey players were 29,9±0,95 μmol/L, which was significantly lower than those in the group of swimmers (36,29±0,84 μmol/L) at p<0,001. In the ice-hockey players and swimmers, the BC/FC ratio was 0,54±0,02 and 0,46±0,02, respectively (the differences were significant; p<0,01. Analysis of gender-related differences revealed the lowest FC level in the group of female ice-hockey players and the highest BC/FC ratio in that of male ice-hockey players. This suggests that the swimmers, cyclical sports representatives (who perform mainly aerobic activity), have a more effective cellular energy.
