[en] Background. The gluteus medius (GM) is a muscle with great importance in the biomechanical control of the lumbopelvic complex and the lower limb during gait, as well as other functional activities. Weakness at the level of this muscle generates altered movement patterns that could lead to a future musculoskeletal pathology. Objetive. Determine the impact of various exercises on the GM. Methods. A bibliographic review of the Cochrane Library, Pubmed, Scopus, SPORTDiscuss and PEDro databases of articles published in the last 5 years that address the impact of different exercises on the GM muscle is carried out. Outcomes.Based on the selection criteria used in this review, a total of 13 observational studies were analysed. The variables studied were the activation of GM and activation ratio compared to other muscles. We analyzed 56 exercises observing increases in GM activation in different proportions ranging from 8% to 99.9% of the maximum voluntary isometric contraction (MVIC).The trigger ratio values range from a minimum of 0.8 to a maximum of 9.29. Conclusions. The different exercises aimed at GM's work generate an increase in muscle activation in different proportions: muscle activation of less than 20% of the MVIC (low level), between 21 and 40% (moderate level), between 41-60% (high level) and more than 60% (very high level), as well as improvements in the activation ratio in some of these exercises. The exercises used in GM's work that present a greater activation (>60% MVIC) are: in unloading the 10 RM hip abduction in lateral decubitus (99.9%) and the isometric abduction of the hip in position of internal rotation (RI) in lateral decubitus (61%); and in loading the hip hitch swing for anterior fibers (68%), the hip abduction in stance at 30° (64.68%), forward step up (62%) and lateral step up (61%).The GM/Tensor fascia latae activation ratio (TFL) experiences its highest value during clamshell.

[gl] Introdución. O glúteo medio (GM) é un músculo con gran importancia no control biomecánico do complexo lumbopélvico e do membro inferior durante a marcha, así coma doutras actividades funcionais. Unha debilidade a nivel deste músculo xera patróns de movemento alterados que poderían derivar en futuras disfuncións musculoesqueléticas. Obxectivo. Determinar a repercusión de diversos exercicios no GM. Material e método. Lévase a cabo unha revisión bibliográfica nas bases de datos The Cochrane Library, Pubmed, Scopus, SPORTDiscuss y PEDro de artigos publicados nos últimos 5 anos que aborden a repercusión de diferentes exercicios no músculo GM. Resultados. En base aos criterios de selección empregados nesta revisión analizanse un total de 13 estudos observacionais. As variables estudadas foron a activación do GM e ratio de activación comparandoo con outros músculos. Analizáronse 56 exercicios observando incrementos na activación do GM en diferentes proporcións que fluctúan entre o 8 % e o 99,9 % da contracción isométrica voluntaria máxima (MVIC). Os valores do ratio de activación oscilan entre un mínimo de 0,8 e un máximo de 9,29. Conclusións. Os distintos exercicios orientados ao traballo do GM xeran un aumento da activación do músculo en diferentes proporcións: activación muscular menor do 20% da MVIC (nivel baixo), entre 21-40% (nivel moderado), entre 41-60% (nivel alto) e maior do 60% (nivel moi alto), así coma melloras no ratio de activación nalgúns destes exercicios. Os exercicios empregados no traballo do GM que presentan unha maior activación (>60%) son: en descarga a 10 RM abducción de cadeira en decúbito lateral (99,9%) e a abducción de cadeira en posición de rotación interna (RI) en decúbito lateral (61%); e en carga o hip hitch swing para fibras anteriores (68%), a abducción de cadeira en bipedestación a 30° (64,68%), forward step up (62%) e o lateral step up (61%). O ratio de activación GM/Tensor da fascia lata (TFL) experimenta seu maior valor durante o clamshell.
