El objetivo del presente estudio fue relacionar la intención de ser activo y la práctica de acti-vidad física extraescolar en 408 escolares. Para la medición de la actividad física extraescolar se empleó el instrumento de recordatorio de la actividad física extraescolar (PDPAR) y para la intención de ser activo el instrumento de Medición de la Intencionalidad de Ser Activo (MIFA). Los resultados mostraron asociaciones significativas entre la intención de ser activo y las medias de minutos de actividad física extraescolar de moderada a vigorosa intensidad en varones y en mujeres. Se observa como los niveles de actividad física aumentan conforme se incrementa la intencionalidad de ser activo.

The aim of this study was to observe the relationship between the intention to be physically active and the after-school physical activity among 408 schoolchildren. The Previous Day Physical Activity Recall (PDPAR) was administered to measure physical activity, while the Intention to be Physically Active Scale (MIFA) was administered to measure the intention to be physically active. The results showed a significant association between the intention to be active and the average time involved in after-school physical activity from moderate to vigorous intensity in males and females. Physical activity levels increase as the intention to be active increases.
