Supplementary material Next-generation sequencing reveals that miR-16-5p, miR-19a-3p, miR-451a and miR-25-3p cargo in plasma extracellular vesicles differentiates sedentary young males from athletes.

<p>A sedentary lifestyle is a leading risk factor for global mortality. No objective molecular biomarker of sedentarism is available. Extracellular vesicles miRNAs have been described to respond to exercise. Our aim was to identify the extracellular vesicle miRNA profile of chronically trained young male athletes, endurance and resistance, compared to their sedentary counterparts. A descriptive case-control design with 16 sedentary young men, 16 Olympic male endurance athletes and 16 Olympic male resistance athletes. Next Generation Sequencing and RT-qPCR, external and internal validation, were performed in order to analysed extracellular vesicle miRNA profiles. miR-16-5p, miR-19a-3p and miR-451a were significantly upregulated in SED compared to END and RES. Besides, miR-25-3p was specifically down-regulated in END compared to SED. Extracellular vesicle miR-16-5p, miR-19a-3p, miR-451a provide an objective signature of sedentarism irrespective of the type of exercise and miR-25-3p as a specific responder to endurance training. Therefore, this study provides for the first time an objective measure to categorise individuals as sedentary or trained in young male population and moreover, it highlights a common epigenetic modulation between models of training.</p&gt
