Non-enzymatic antioxidant blood plasma profile in the period of high training loads of elite speed skaters in the altitude.

At the altitude, hypoxia and training load are key factors in the development of oxidative stress. Altitude-induced oxidative stress is developed due to the depletion of antioxidant potential. In the current study, we examined the non-enzymatic antioxidant profile of blood plasma in 7 males and 5 females specializing in speed skating at a 21-day training camp at 1 850 ​m above sea level.

[Polymorphism of Uncoupling Protein Genes in Football Players: Investigation of the Functional Role.].

We studied the polymorphism of uncoupling protein genes (families UCPI, 2 and 3) and FTO gene in football players and compared the results with the data obtained in non-sportsmen. All these genes encode the proteins that take part in the regulation of body weight. However, we observed an increased percentage of the carriers of "sparing" allele of the UCP3 gene; the allele frequency of other studied genes showed the same tendency.
