ABSTRACT

RESUMEN: El objetivo de este estudio fue describir la frecuencia genotípica y alélica del ACTN3 R577X y ECA I/D en atletas ciegos de fútbol 5. Se incluyó una metodología descriptiva con una muestra de 63 deportistas ciegos (28,0±5,8 años), todos varones, de equipos de fútbol 5 de alto rendimiento. El polimorfismo se determinó mediante la reacción en cadena de la polimerasa en tiempo real (RT-PCR). La estadística fue descriptiva realizada a partir de las medidas de frecuencia de genotipos y alelos. La frecuencia genotípica de la ACTN3 en los deportistas presentó la siguiente distribución: el 28,6 % con genotipo RR, el 54 % con RX y el 17,4 % con XX y frecuencia alélica del 55,6 % para el alelo R y del 44,4 % para el alelo X. En cuanto a la ECA I/D, la frecuencia genotípica fue del 63,5 % para el genotipo ID, del 22,2 % para el DD y del 14,3 % para el II. La frecuencia alélica presentó prevalencia del alelo D con el 53,9 %. El estudio constató una predominancia de los genotipos y alelos representativos de las modalidades de fuerza y velocidad para ACTN3 R577X y ECA I/D de atletas de fútbol 5.


SUMMARY: 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.

ABSTRACT

Introduction: Football 5-a-side is a sport played by blind athletes that takes part in the Paralympic Games since 2004. The Brazilian national team is currently considered the best team in the world in this sport. Objective: To analyze the variations of intensity of effort (average per position and group average) made by blind athletes of the Brazilian football 5-a-side national team during six matches simulations. Methods: The sample on this research is the intentional type, made with eight blind male players, ages ranging from 21 to 30 years old (23.8 ± 3.3), all of them part of the Brazilian Football 5-a-side National team, which played in the 2012 Paralympics Games in England. In was evaluated the VO2máx and the heart rate during six simulations of official matches. Results: The intensity of effort of the blind athletes of the Brazilian Football 5-a-side National Team is intermittent and remains 52.5 % of the total time of a match (50 minutes) with an intensity of effort between the zone 2 (between threshold ventilation and respiratory compensation point) and the zone 3 (above the respiratory compensation point) averaging 89.8 % of the HR max. Conclusion: The intensity of effort is greater than the Football of 11 and, that in the Futsal players. (AU)


Introdução: O Futebol de 5 é um esporte praticado por atletas cegos, que participa das Paraolimpíadas desde 2004. A seleção Brasileira foi considerada a melhor equipe do mundo nessa modalidade entre os anos de 2004 e 2016. Objetivo: analisar as variações da intensidade de esforço (média por posição e média do grupo) realizados pelos atletas cegos da Seleção Brasileira de Futebol de 5 durante seis simulações de partidas oficiais (coletivos). Métodos: A amostra desta pesquisa é do tipo intencional, constituída por oito jogadores cegos do sexo masculino, com idades que variam de 21 a 30 anos (23,8±3,3) convocados para a Seleção Brasileira de Futebol de 5, que disputaram as Paraolimpíadas na Inglaterra em 2012. Foram avaliados o VO2máx e a Frequência Cardíaca durante as seis simulações de partidas oficiais. Resultados: A intensidade de esforço dos atletas cegos da Seleção Brasileira de Futebol de 5 é intermitente por permanecer 52,5% do tempo total de uma partida desta modalidade (50 minutos) com intensidade de esforço entre as zonas 2 (entre o Limiar Ventilatório e o Ponto de Compensação Respiratória) e zona 3 (acima do Ponto de Compensação Respiratória), atingindo uma média de 89,8% da FC máx. Conclusão: A intensidade de esforço é maior que o Futebol de 11 e, que no Futsal. (AU)
