Resumen

El objetivo de esta revisión es identi'car los niveles de actividad física por medio de acelerometría en alumnos de edad escolar y analizar el cumplimiento de las recomendaciones de actividad física. Se realizó una revisión de la literatura de los artículos incluidos en las bases de datos Medline/Pubmed y Scielo que utilizaran acelerómetros con participantes en edad escolar, entre enero de 2004 y mayo de 2013, seleccionándose 98 artículos cientí'cos. Se muestran valores de referencia en diferentes etapas educativas, posibilidades de actividad física que ofrece el contexto escolar, así como programas de intervención, donde en términos generales se observa un bajo nivel de actividad física. A su vez, se observa un escaso cumplimiento del mínimo nivel de actividad física recomendada como saludable. En conclusión, esta revisión contribuye a orientar las futuras investigaciones en este campo, fundamentalmente destinadas a llevar a cabo programas de intervención.
