Introduction: Aging is associated with a chronic low-grade inflammatory process characterized by an increased production of inflammatory mediators. These elevated levels are predictors for muscle function (sarcopenia) and deterioration of physical performance in the elderly. Objective: To investigate the correlation between sarcopenia, functional capacity, and interleukin-6 levels. Materials and methods: This crosssectional study assessed a convenience sample of elderly individuals (n = 130) using a handgrip dynamometer (JAMAR™), and the functional capacity test was performed by sitting and standing. Interleukin-6 levels were determined using high sensitivity ELISA kits. Spearman correlation coefficient was used to assess the correlation between these variables, at a significance level (α) of 0.05. Results: There was significant
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
