ABSTRACT
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.

The purpose of this study is to analyze acute effect of running extended interval training(EIT) on vertical jump (VJ) and handgrip strength (HS) performance in experienced endurance athletes. In order to analyze mechanical parameters of the VJ and HS between runs, sixteen experienced male athletes performed an EIT (4x3x400m). The results show that fatigue induced by EIT does not impair handgrip strength or VJ performance. A significant improvement (p< .05) was noted for VJ due to the postactivation potentiation (PAP) phenomenon. A positive correlation (r= .619, p= .011) was found between VJ and lactate. The results suggest that experienced long-distance runners can maintain their strength levels and, consequently, work capacity, despite the induced fatigue by the field training demand. Therefore, VJ performance during EIT can be used as an indicator of muscular adaptations to training and, together, with handgrip strength, become indicators of fatigue. These indicators allow proper prescription training routines...
"Fadiga concorrente e potenciação pós-ativação durante o treinamento intervalado extensivo em corredores de fundo." O objetivo do estudo é analisar a relação entre a fadiga e a potenciação pós-ativação (PPA) nos corredores de fundo durante uma sessão de treinamento típico, extensivo treinamento intervalado (ETI). Dezesseis atletas experientes executaram o ETI (4x3x400m) e se avaliou o desempenho entre as repetições e os parâmetros mecânicos associados ao salto vertical (SV) e à força de preensão manual. Os resultados mostram que o ETI não deteriora o desempenho dos atletas neste nesta prova e que inclusive há um aumento no SV (p< 0,05), devido ao fenômeno do PPA. Verificou-se uma correlação entre SV-lactado (r= 0,619, p= 0,011). Os dados obtidos sugerem que os atletas de resistência podem manter os níveis de força e a capacidade de trabalho apesar de fadiga induzida por ETI. O desempenho no SV para um ETI pode ser indicador de adaptações musculares do treino que, junto com a força de preensão manual, podem ser utilizadas como ferramentas para prescrição de treinamento...
"Fatiga concurrente y potenciación postactivación durante el entrenamiento interválico extendido en corredores de resistencia." El objetivo del estudio el efecto de un entrenamiento interválico extensivo (EIE) en el rendimiento en salto vertical (SV) y dinamometría manual en corredores de resistencia. Dieciséis atletas experimentados ejecutaron el EIE (4x3x400m), y se evaluó entre repeticiones el rendimiento en SV y parametros mecánicos asociados, y en fuerza de prensión manual. Los resultados muestran que EIE no deteriora el rendimiento en dichos test, e incluso aumenta significativamente en SV (p< 0,05) debido al fenómeno de potenciación postactivación (PPA). Se halló correlación entre SV y lactato (r= 0,619; p= 0,011). Los datos obtenidos sugieren que atletas de resistencia pueden mantener niveles de fuerza y capacidad de trabajo a pesar de la fatiga inducida por este entrenamiento en pista. El rendimiento en SV durante un EIE puede usarse como indicador de adaptaciones musculares al entrenamiento y, junto a fuerza de prensión manual, podrían utilizarse como herramientas para la prescripción del entrenamiento...
