Abstract: | The distribution of genotypes and alleles of ACE (I/D polymorphism), ACTN3 (R577X), NOS3 (5/4), UCP2 (Ala55Val), and UCP3 (-55C/T) genes, as well as the correlation between the genotype and physiological parameters, was studied in rowers (n = 230) and in a control group (n = 855). The genotypes were determined by analyzing restriction fragment length polymorphism. Physiological parameters were determined with a PM 3 rowing ergometer and a MetaMax 3B gas analyzer. The frequency of the ACE II genotype was significantly higher in elite rowers (n = 107) than in the control subjects. The frequency of the ACTN3 XX genotype, unfavorable for development of speed and strength qualities, was twofold lower in all rowers than in the control subjects. The frequencies of the ACE I, ACTN3 R, UCP2 Val, and UCP3 T alleles increased in the athletes along with an increase in skill, which suggested natural sports selection. In addition, ACE I, NOS3 5, UCP2 Val, and UCP3 T alleles correlated with a high aerobic performance. Thus, the ACE I, NOS3 5, UCP2 Val, and UCP3 T alleles may be regarded as genetic markers associated with enhanced aerobic performance and may be included in a diagnostic system for prognosis of human physical performance. |
