Abstract
El fortalecimiento de los músculos del cuádriceps femoral (CF) es importante debido a su función en el movimiento. La posición de la articulación puede generar cambios en el reclutamiento muscular. De esa forma el presente estudio tiene como objetivo verificar si variaciones en las posiciones del pie durante la extensión de las rodillas son eficaces para la selección específica de los músculos recto femoral, vasto lateral y vasto medial, que componen el CF. Once mujeres universitarias (edad 22.36 ± 3.56 años) participaron del estudio. Fue evaluada la activación de los músculos a través de la electromiografía de superficie, con una configuración bipolar, en 3 series de 10 repeticiones máximas (RM) de extensión bilateral de rodilla, en tres posiciones de los pies: neutra, rotación interna y rotación externa. Los resultados no presentaron diferencias significativas entre los músculos del CF en todas las posiciones del pie. En conclusión, los resultados del presente estudio sugieren que las variaciones en los grados de rotación de los pies durante la extensión de las rodillas no son eficaces para la selección específica de los músculos que componen el CF.
