Abstract
- • This study was conceived as a means of finding out when exactly ACE I/D and ACTN3 R577X start being physically discriminative. Initially, no statistical association was found because the genetic effect was masked by those subjects with sedentary lifestyles. But when only physically active volunteers were considered, the effect of ACE and ACTN3 genotypes were found to be significant. This can therefore be considered a paradigmatic example in which the environment might hide the genetic effect, with genotypic differences arising only upon training. Genome variations contribute to the vast majority of interindividual differences and may decisively influence sports capability. This study was conceived as a means of finding out when exactly polymorphisms start being physically discriminative. The polymorphisms we studied were two of the best characterized ones: ACE I/D and ACTN3 R577X. These germline variants were determined in a cohort of 200 healthy volunteers from the university environment who underwent a series of physical evaluations that included a Cooper test, a 20-meter sprint test and a vertical jump test. Initially, no statistical association was found because the genetic effect was masked by those subjects with sedentary lifestyles. But when only physically active volunteers were considered, the ACE and ACTN3 genotypes were found to have an impact on heart rate after the Cooper test (p-value = 0.033 and 0.032 respectively) and ACTN3 was found to correlate with the total distance covered in the same test (p-value = 0.051). This can therefore be considered a paradigmatic example in which the environment might hide the genetic effect, with genotypic differences arising only upon training. [ABSTRACT FROM AUTHOR]
