El recreo escolar, es un periodo importante para el desarrollo social, emocional, físico y cognitivo de los escolares. El objetivo fue verificar si los niveles de actividad física (AF) durante un recreo escolar disminuyen según edad y tamaño corporal durante la adolescencia. Se efectuó un estudio descriptivo transversal-correlacional en 42 adolescentes escolares (21 Hombres y 21 mujeres) 10 y 14 años pertenecientes a un establecimiento Municipal de la Provincia de Talca (Chile). Fueron evaluadas las variables antropométricas de peso corporal (kg), estatura (cm). Para el tamaño corporal se usó la fórmula de Haycock, et al (1978) que estima el área de superficie corporal (ASC). Los niveles de AF fueron medidos a través de la cantidad de pasos efectuados durante el recreo escolar (20 minutos), a través del uso de podómetros. El número de pasos que efectuaron los hombres fue de 4268,9±1103,0 pasos y en mujeres fue de 2490,0±1487,3 pasos. La relación entre el número de pasos con la edad cronológica en hombres fue de r= -0,33 y en mujeres fue de r= -0,53. Los valores del tamaño corporal aumentan a medida que los niveles de AF (número de pasos en el recreo) disminuyen, en hombres fue de r= -0,24 y en mujeres de r= -0,29. Este estudio demostró que a medida que avanza la edad y el tamaño corporal entre los adolescentes, disminuye el número de pasos dados durante un recreo escolar, siendo esta reducción más marcada en mujeres que en hombres.
