RESUMEN
miRNAs are involved in the generation and progression of musculoskeletal pain, a condition that causes significant clinical, economic and social burden. In runners, the presence of musculoskeletal pain related to an inflammatory state or ongoing underlying tissue damage may result in poor training ability and performance. This study aims to evaluate the association between circulating and salivary miRNAs and pain in runners with and without musculoskeletal pain and to observe whether dysregulated miRNAs can distinguish between responders and nonresponders to a kinesiological intervention. The possible correlation between these miRNAs and inflammatory molecules, stress parameters and individual or behavioral characteristics will be evaluated. Finally, in silico analysis will be used to characterize miRNAs function. Ethics approval was obtained.

The term 'lifestyle' includes different factors that contribute to the maintenance of a good health status. Increasing evidences suggest that lifestyle factors may influence epigenetic mechanisms, such as miRNAs expression. The dysregulation of miRNAs can modify the expression of genes and molecular pathways that may lead to functional alterations. This review summarizes human studies highlighting that diet, physical activity, smoking and alcohol consumption may affect the miRNA machinery and several biological functions. Most miRNAs are involved in molecular pathways that influence inflammation, cell cycle regulation and carcinogenesis resulting in the onset or progression of pathological conditions. Investigating these interactions will be pivotal for understanding the etiology of pathologic processes, the potential new treatment strategies and for preventing diseases.
