Effects of Eccentric Exercise on Muscle Architecture in Adults: A Systematic Review

The purpose of this systematic review was to determine the effects eccentric training on muscle architecture in adult population. Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) statements were followed using keywords associated with muscular training. Four databases used: PubMed, Scopus, SPORTDiscus Web Science. Methodological quality assessed PEDro scale. A total 1260 articles retrieved, 18 included review. parameters most frequently evaluated studies consulted pennation angle (PA), fascicle length (FL), thickness (MT). These mainly lower limb muscles such as biceps femoris long head (BFlh), vastus lateralis (VL), medial gastrocnemius (MG) lateral (LG), respectively. Eccentric at least four weeks generates adaptations these parameters, by increasing MT FL decreasing PA, determining function. results provide evidence architecture, which could be helpful prevent injuries favor recovery processes.
