摘要：Different factors affecting athletic performance are well established: intensity and type of training, anthropometric characteristics as well as an important psychological component. However, the contribution of the genetic background has been less investigated. The aim of the present study was to investigate the influence of polymorphisms within genes associated with stress and anxiety (5HTT, CRH2R, ACE, NK1R, 5HT1AR and CRF-BP) on the physical capability and sports performance in triathletes. One hundred and ninety two (192) unrelated Chilean triathletes who participated in the 2014 70.3 Pucón city triathlon were divided into opposite subgroups of sports performance according to their time results. We identified significant associations for five polymorphisms (5HTT 5-HTTLPR, ACE I/D, NK1R rs6715729, 5HT1AR -1019C>G and CRF-BP CRF-BPs11) with athletic performance. Our results indicate that these polymorphisms are associated with differential sports performance in Chilean triathletes, establishing an initial background for better understanding the relationship between physical performance, genetics and anxiety disorders.
