Ativação da musculatura do tronco durante a realização de exercícios dinâmicos de membros inferiores em cadeia cinética fechada: uma revisão sistemática

Abstract

Introduction: The trunk muscles are part of the core, which is responsible for lumbopelvic complex stability and responsible for transferring forces between limbs kinetic chains. Closed kinetic chair exercise implementation is increasing because it is more functional than specific exercises for trunk muscles and moves multiples joints, recruiting several muscle groups synergistically. The importance of implementation of trunk muscle exercises in a training program is clear, but we still discuss about what kind of exercise we should use, the specifics exercises for trunk of global exercises. Objective: The purpose of this systematic review was to investigate the trunk muscle activation during lower limb closed kinetic chain exercises. Methodology: The research was conducted in three different electronic databases: MEDLINE, Cochrane and Scielo, and used the terms: electromyography”, “EMG”, “core muscle activity”, “trunk muscle activity”, “core muscle activation” e “trunk muscle activation”, each one were individually combined with the following terms: “dynamic exercise”, “squat”, “deadlift” ou “free weight exercise”. It was connected by the boolean AND. Article published between 2010 and 2020 were included and no restriction about language was made. Results: 1309 articles were found, but only 4 met the criteria and were included in this study. Conclusion: The lower limbs closed kinetic chain exercises are efficient in activating the trunk muscle, however more studies are needed. Studies more standardized, with a bigger sample, different person profile and investigating other muscles.
