Description
Summary:The angiotensin converting enzyme gene (ACE) has been associated with endurance and strength performance through its I/D polymorphism. Nevertheless, contradictory results exist between different populations. In this context, the purpose of this research was to determine the influence of the I/D polymorphism of the ACE gene on muscle strength in a sedentary Chilean sample. In this study 102 healthy male students (21.3 [+ or -] 2.2 years) completed the assessment. I/D genotyping, cardiovascular, anthropometric, grip strength and knee extensor peak strength were evaluated. The ACE polymorphism frequency was: II, 33.3 %; ID, 46.1 %; DD, 20.6 %. The results showed significant differences and large effect size in maximum (p = 0.004; d = 0.85) and relative handgrip strength (p = 0.004; d = 0.9) between genotype II vs DD. No difference was found for maximal or relative knee extensor strength between groups (p = 0.74), showing a low effect size (d = 0.20). In conclusion, this study provides insights into the role of the ACE gene in muscle strength and highlights the importance of investigating genetic variants in sedentary populations to better understand strength performance.

El gen de la enzima convertidora de angiotensina (ACE) se ha asociado con el rendimiento de resistencia y fuerza a traves de su polimorfismo I/D. Sin embargo, existen resultados contradictorios entre diferentes poblaciones. En este contexto, el proposito de esta investigacion fue determinar la influencia del polimorfismo I/D del gen ACE sobre la fuerza muscular en una muestra chilena sedentaria. En este estudio, fueron evaluados 102 estudiantes varones sanos (21,3 [+ or -] 2,2 anos). Se realizaron aplicaron las siguientes evaluaciones: genotipado del polimorfismo I/D, cardiovascular, antropometrica, fuerza de prension y fuerza maxima de extension de rodilla. La frecuencia del polimorfismo I/D de ACE fue: II, 33,3 %; DNI, 46,1 %; DD, 20,6 %. Los resultados mostraron diferencias significativas y un gran tamano del efecto en la fuerza maxima (p = 0,004; d = 0,85) y relativa de prension manual (p = 0,004; d = 0,9) entre el genotipo II y el DD. No se encontraron diferencias en la fuerza maxima o relativa de los extensores de rodilla entre los grupos (p = 0,74), lo que muestra un tamano de efecto bajo (d = 0,20). En conclusion, este estudio proporciona informacion sobre el papel del gen ACE en la fuerza muscular y destaca l
