Abstract:
The aim of this meta-analysis was to investigate the effects of high levels of physical activity (in elite athletes) and sedentary lifestyle on telomere length. Our meta-analysis was carried out using the following electronic databases: PubMed, Cochrane Library, LILACS, Science Direct and EBSCO. After study selection, nine articles were included in our meta-analysis. All of the included subjects were elite athletes (with experience in national or international competitions) or sedentary subjects, which served as the control group. The analysis showed that elite athletes (n = 306) had longer telomeres (P = 0.001) compared with the control group (n = 322). The difference in the standardized means was 0.91 (95% CI = 0.43-1.33; I2 83.4% P value for heterogeneity = 0.001), favoring the athlete group. The analysis of the funnel plot did not detect any risk of publication bias in the studies that reported differences in means. Our results suggest that high level chronic physical training may provide protective effects on telomere length.

A generalized loading function is employed to analyze a cable subjected to its own weight. This function considers the force acting along the cable's arc length rather than its projected length, providing a more accurate...
