El objetivo del presente estudio fue dotar a los alumnos de una herramienta que les permitiese controlar la intensidad de su actividad física utilizando para ello la valoración subjetiva del esfuerzo. 32 sujetos (n1=12 niños y n2=20 niñas) de 11,5 ± 0,5 años participaron en un programa de entrenamiento en circuito integrado por seis postas. Se registró la frecuencia cardiaca con pulsómetros y la percepción subjetiva del esfuerzo mediante la escala OMNI. Tras las siete sesiones del programa se observaron correlaciones muy altas entre ambos parámetros (r=0,54-0,76). Una vez finalizado el estudio los alumnos fueron capaces de regular su esfuerzo dentro de un rango de frecuencia cardiaca establecido en un 53,13% respecto a la frecuencia cardiaca percibida y 56,25% respecto a la frecuencia cardiaca medida, facilitándoles así un procedimiento práctico para el control de la intensidad durante la actividad física.
Palabras clave: salud, actividad física, intensidad, valoración subjetiva, escolares.

Abstract
The aim of the present work is to give up the pupils a simple tool that let them to control the intensity of their physical activity using in this way the rating of perceived exertion. 32 subjects (n1=12 boys and n2=20 girls), 11.5 ± 0.5 years old were involved in a physical activity program on a six-station circuit. Heart rate and rating of perceived exertion with the OMNI scale were meassured. After seven sessions were observed high correlations between both parameters (r=0.54 - 0.76). Once the program finished the pupils could regulate their effort in a 53,13% with perceived heart rate and 56,25% with real heart rate, inside an established heart rate range, giving them a practice procedure to control the intensity of their physical activity while exercising.
Key words: health, physical activity, intensity, perceived exertion, pupils.
