No significant differences were observed in genotype and allele distributions among the study groups except for the ADRB3 Trp64Arg polymorphism in E versus C (27% vs 8% of carriers of the Arg allele in E and C, p<0.001; frequency of the minor Arg (C) allele of 14% vs 4% in E and C, p=0.001). Heterozygosity for the ADRB3 Trp64Arg polymorphism seems to be associated with elite endurance performance, while other variants of the β-adrenergic receptors' genes do not seem to significantly influence top-level sports performance, at least in athletes of Spanish origin.
