ABSTRACT
El objetivo de este trabajo fue analizar el efecto sobre la atención de escolares de dos programas de actividad física (moderada y alta intensidad). Participaron 94 niños (n = 52) y niñas (n =42), (Edad M = 8,20; DT = 0,70) de la ciudad de Granada (España). Se empleó un diseño cuasi-experimental con un grupo control y otro experimental. Se analizó amplitud de la atención y atención selectiva. Como variable de control se evaluó la aptitud cardiorrespiratoria a través de consumo de oxígeno máximo y la velocidad pico alcanzada durante actividad aeróbica máxima. Se aprecian efectos significativos a favor del programa de alta intensidad sobre dos pruebas de span atencional y ejercicios de atención selectiva, así como en valores de condición física. Se concluye que la práctica física de alta intensidad intermitente, practicada de manera regular, podría tener implicaciones positivas sobre el rendimiento cognitivo de niños y que la mejora de la condición física podría ser uno de los factores vinculados a estos cambios (AU)
The aim of this study was to analyze the effect of two programs of physical activity (moderate and high intensity physical activity), in the levels of attention of a sample of young in scholar aged. 94 children, boys=52 and girls=42 (Age M = 8.20; SD = 0.70) from Granada (Spain) participated in the investigation. A quasi-experimental design was used, with control and experimental group. Evidence of attentional span and search items on matrices with the purpose of analyzing the amplitude of the attention and selective attention were applied. As a control variable, cardiorespiratory fitness by maximum oxygen uptake and peak speed reached during maximal aerobic activity was evaluated. The results showed significant effects in favor of high-intensity program on two tests of attentional span and exercises selective attention, as well as the values of fitness. These data suggest that the physical practice of intermittent high intensity practiced regularly could have positive implications on cognitive performance of children and improving the physical condition could be one of the factors linked to these changes (AU)
O objetivo deste estudo foi analisar o efeito de dois programas de atividade física (de intensidade moderada e alta) em atenção o nível cognitivo para a escola. 94 estudantes participaram, 52 do sexo masculino, 42 do sexo feminino (Idade M = 8,20, DP = 0,70) da cidade de Granada (Espanha). Um design quase-experimental foi utilizado com um grupo controle e um grupo experimental. Amplitude de atenção e atenção seletiva foram analisados. Como variável de controle foi avaliada a aptidão cardiorrespiratória através do consumo máximo de oxigênio e velocidade de pico alcançado durante a atividade aeróbica máxima. Efeitos significativos são vistos em favor do programa de alto intensidade e dois exercícios de amplitude e exercícios de atenção selectiva, bem como valores de aptidao física. Conclui-se que a prática física de alta intensidade intermitente, praticado regularmente, pode ter implicações positivas sobre o desempenho cognitivo das crianças e condição física melhoria poderia ser um dos fatores ligados a essas mudanças (AU)

The purpose of this review was to analyze the scientific production about extra-curricular physical activity (PA) in western children of 6-12 years. Medline / Pub-Med, Scopus and Google Scholar were used. This search collects articles published between January 1990 and May 2013. A total of 104 publications were analyzed. The body composition parameters are best used to assess the results of the studies, followed by those which estimate the maximum aerobic capacity. Articles of intervention are presented with very heterogeneous methodological features but there are clear trends in the use of certain aspects. As for the reviews, most are systematic and include meta-analysis. In this studies, body mass index (BMI) is the most used parameter.

El objetivo fue realizar un análisis de la producción científica desarrollada hasta la fecha sobre actividad física (AF) extra-curricular en niños occidentales de 6 a 12 años. Se utilizaron las bases de datos Medline/Pub-Med, Scopus y metabuscador Google Scholar para recoger artículos publicados entre enero de 1990 y mayo de 2013. Se analizó un total de 104 publicaciones. Los parámetros de composición corporal son los más utilizados para valorar los resultados de los estudios, seguidos de aquellos que estiman la capacidad aeróbica máxima. Los artículos de intervención se presentan con unas características metodológicas muy heterogéneas, aunque existen tendencias claras en el uso de determinados aspectos. En cuanto a las revisiones, la mayoría son sistemáticas e incluyen metaanálisis; el índice de masa corporal (IMC) es el parámetro más utilizado.
