The effect of long-term ultra-endurance exercise and SOD2 genotype on telomere shortening with age

2020

Telomere shortening, a well-known biomarker of aging, is a complex process influenced by several intrinsic and lifestyle factors. Although habitual exercise may promote telomere length maintenance, extreme endurance exercise has been also associated with increased oxidative stress—presumed to be the major cause of telomere shortening. Therefore, the pace of telomere shortening with age may also depend on antioxidant system efficiency, which is, in part, genetically determined. In this study, we aimed to evaluate the impact of ultra-endurance exercise and oxidative stress susceptibility (determined by the rs4880 polymorphism in the superoxide dismutase 2 (SOD2) gene) on telomere length.
