Association of the ACTN3 R577X polymorphism in Polish rowers

Abstract

Background: The ACTN3 R577X polymorphism has been associated with an elite athlete status. Several studies have determined that the R allele is connected with power-oriented athletic performance, whereas the nonfunctional XX genotype may give some beneficial effect for endurance performance. The main aim of the study was to determine the possible interaction between the ACTN3 R577X polymorphism and an endurance athlete status in a group of Polish rowers in comparison with sedentary individuals.
