Abstract: The objective: To study the features of carnitine and amino acid metabolism in young athletes.
Materials and methods: 131 children (I-II health groups) aged 12 to 17 years 11 months were examined. The main group is 94 young athletes. Control group - 37 children who do not engage in sports. Determination of the level of free and bound carnitine, amino acids by tandem chromatography-mass spectrometry.
According to the results of the examination of two groups of children, the content of free carnitine is significantly higher in young athletes (p <0.05). Significant differences exist in the free / bound carnitine index. This figure is significantly higher among athletes (p <0.05). The reliability of differences in the content of methionine was noted at p Conclusion indicate the presence of a number of features of carnitine status and amino acid metabolism in young athletes. It can be assumed that the obtained data reflect a more efficient cellular energy in children involved in sports.
