Running Economy And Cytokines: What The Influence Of Il-6 And Il-10?, Luiz Luna Jr., Roberta Paiva, Ana Sierra, Andre Bachi, Pedro Vaisberg, Mauro Vaisberg

International Journal of Exercise Science: Conference Proceedings

Introduction: During the exercise performing the muscle produce cytokines, named “myokines”. These molecules show autocrine, paracrine and endocrine effects. One of them IL-6 demonstrates both pro and anti-inflammatory actions. Usually they have an anti-inflammatory action when produced by working muscles and when produced by other tissues, especially adipose, they assume a pro-inflammatory profile. Athletes´ performance, especially those that run long distances races (endurance) is associated with higher levels of maximal oxygen uptake (VO2max). Running economy (RE) is a methodology used to evaluate the performance of runners and is defined as "the rate of oxygen consumption (VO2) required for maintain …
