Introducción: El análisis de la intensidad del eco (IE) puede obtenerse mediante ultrasonidos a partir de las reflexiones de las ondas ecográficas del tejido y se ha utilizado ampliamente para identificar el daño tisular en el contexto clínico y deportivo. Las mujeres pueden tener más tejido adiposo que los hombres, lo que puede reflejarse en una mayor infiltración de grasa en el músculo y, por tanto, influir en los valores del IE. Objetivo: Comprobar si el género influye en la IE del cuádriceps femoral en individuos jóvenes y sanos. Materiales y métodos: Diecinueve individuos jóvenes y sanos (9 mujeres y 10 hombres; 26,0 ± 7,0 años; 28,0 ± 6,0 kg/m2) participaron en el estudio. Se adquirieron seis imágenes ecográficas de los músculos recto femoral (RF), vasto lateral (VL) y vasto medial (VM), bilateralmente y en reposo. Los valores del IE se establecieron mediante la función de histograma del software ImageJ®, cuya escala de grises va de 0 (negro) a 255 (blanco). Para comparar la IE entre géneros, se utilizó la prueba estadística ANOVA de modelo mixto con un nivel de significación de ≤ 0,05. Resultados: No se encontraron diferencias significativas entre el IE de los cuádriceps de hombres y mujeres (p = 0,679). Los valores medios de IE encontrados fueron 135,18 ± 11,86, 126,74 ± 14,05 y 131,36 ± 12,81 U.A. para RF, VL y VM, respectivamente. Conclusión: El género no parece influir en los valores del IE del cuádriceps femoral en individuos jóvenes y sanos, lo que puede representar una composición muscular similar entre hombres y mujeres con un índice de masa corporal normal. Otros estudios deberían investigar las diferentes edades y el índice de masa corporal.
