Abstract
Numerosas investigaciones ponen de manifiesto una relación
entre el genotipo del gen ACTN3 y el rendimiento deportivo,
vinculado con la velocidad y fuerza explosiva. El objetivo del
presente estudio fue analizar la relación entre el genotipo de
ACTN3 y el rendimiento deportivo en natación, expresado en
puntuación FINA. Participaron 125 nadadores españoles de
categoría absoluta, 72 varones (48 velocistas, 24 medio
fondistas-fondistas) y 53 mujeres (29 velocistas, 24 medio
fondistas-fondistas). Los resultados muestran cómo la
puntuación FINA entre los nadadores velocistas y de medio
fondo-fondo, no guarda relación con los distintos genotipos
para el gen ACTN3. Mientras que en los varones velocistas no
encontramos si quiera una ordenación del rendimiento en
función de los genotipos de ACTN3, las mujeres con genotipo
RR muestran un rendimiento superior a aquellas con genotipo
RX, y éstas mayor que las del genotipo XX.
A large amount of researches has shown that ACTN3 genotype is associated to high performance in sports, more specifically it is related to speed and explosive strength. The aim of this study was to analyze the relation between ACTN3 genotype and sports performance in swimming, expressed in FINA score. A total of 125 Spanish swimmers of senior category, 72 males (48 sprinters, 24 middle distance-long distance) and 53 females (29 sprinters, 24 middle distance-long distance) participated in this study. We did not found any relation between FINA score and the different ACTN3 genotypes, regardless the swimmers type. However, sprinters women with genotype RR show superior performance to those with genotype RX, and these more than the XX genotype.
