PURPOSE: The telomere length (TL) of middle aged master runners (RUN) (n = 23, 52.3 ± 8.6 yrs; 12 sprinters, SPT; 11 endurance runners, END) was compared to untrained controls (CON, n 10; 43.7 9.4 yrs), and the relationships between TL both athletes’ performance body composition were analyzed. METHODS: Participants had blood samples collected for biomolecular measures. Relative leucocyte (T/S) measured through qPCR. ANOVA unpaired t-tests applied compare studied groups, Pearson’s moment correlation verify relationships. RESULTS: all RUN (T/S 1.24 0.73) differ from CON 0.515 0.62) (p < 0.01), while SPT 1.495 0.85) trended be longer than END 0.954 0.46) 0.076) with a large effect size (d 0.72). It observed significant actual level as percentage current world record (r 0.47, p negative fat entire sample -0.447; 0.01). Furthermore, decline per decade -0.651, CONCLUSIONS: In conclusion, athletes their peers, seems not only marker health status, but also an indicator sports longevity since level, its decrease over years, related sample.
