Abstract:
BACKGROUND: Increasing evidence shows that at least 155 genetic polymorphisms are associated with aerobic performance and elite endurance athlete status. OBJECTIVE: To study the association of α-actin 3 (ACTN3) gene, nuclear respiratory factor 2 (NRF2), β2 adrenergic receptor (ADRB2) gene and peroxisome proliferative activated receptor gamma coactivator 1 alpha (PPARGC1A) polymorphic loci with aerobic performance of rowing athletes and their interaction effect, thereby providing basis for understanding the mechanism of genetic polymorphisms acting on endurance athlete status. METHODS: A case-control experiment was designed to analyze the distribution characteristics of four gene polymorphism loci in 15 excellent rowing athletes and 50 common college freshmen. The association of four polymorphic loci with the aerobic performance-related indexes was analyzed using total genotype scores. RESULTS AND CONCLUSION: The preponderant polymorphism locus distributions of ACTN3, PPARGC1A and NRF2 in the athletes group were higher than those in the control group, and the NRF2 gene loci showed significant difference between two groups. In the athletes group, the mean values of VO2 maxwas significantly different among three genotypes. That is to say, these three genetic polymorphisms may be the biomarkers to predict the elite endurance athlete status, but the mechanism needs to be studied in depth.
