Resumen

OLIVEIRA, Glauber Lameira et al. Frequency of Genetic Polymorphism ACTN3 R577X and ACE I/D in Blind Athletes of 5-a-Side Football. Int. J. Morphol. [online]. 2020, vol.38, n.5, pp.1336-1340. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022020000501336.

The aim of this study was to describe the genotypic and allele frequency of ACTN3 R577X and ACE I/D in blind athletes of 5-a-side football performance. A descriptive methodology was included with a sample of 63 blind male athletes (28.0 ±5.8 years) of football teams with a 5-a-side performance rating. The polymorphism was determined by means by of real-time Polymerase Chain Reaction (rt-PCR). Statistics were descriptive based on the measures of frequency of genotypes and alleles. The genotypic frequency of ACTN3 by the athletes presented the following distribution: 28.6 % with RR genotype, 54 % with RX and 17.4 % XX and allele frequency of 55.6 % for the R allele and 44.4 % for the X allele. As for ACE I/D, the genotype frequency was 63.5 % for genotype ID, 22.2 % for DD and 14.3 % for II. The allele frequency showed a predominance of the D allele with 53.9 %. The study found for ACTN3 R577X and ACE I/ D of blind athletes of 5-a-side football, a predominance of genotypes and alleles representative of strength and speed modalities.
