Elite swimmers possess shorter telomeres than recreationally active controls

Elite athletes are reported to possess longer telomeres than their less active counterparts. ACE gene (Insertion/Deletion) polymorphism has been previously associated with elite athletic performance, the deletion (D) variant appearing more frequently in short distance swimmers. Additionally, D allele have a negative effect on telomere length. The aim of this study was investigate length swimmers and its potential association genotype. Telomere measured by real-time quantitative PCR I/D genotypes analysed standard electrophoresis 51 young 56 controls. displayed shorter controls (1.043 ± 0.127 vs 1.128 0.177, p = 0.006). When split sex, only female showed significantly recreationally counterparts (p 0.019). genotype distribution allelic frequency did not differ between controls, or event among only. No observed whole cohort. possessed Our findings suggesting high-level swimming competition and/or training subsequent biological aging, particularly females. However, significant difference does appear be attributed as we report lack
