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...
Introduction. The variance in human athletic ability is the result of interaction of both genetic and environmental factors. The ADRA2A gene that encodes adrenergic receptors α2 is likely to be a candidate gene because ADRA2A receptors are crucial for precise cardiovascular control and are involved in the regulation of adipocyte lipolysis, glucose metabolism and insulin secretion. Several genetic...
