Condición física, percepción subjetiva del esfuerzo y rendimiento académico en educación primaria

espanolExisten estudios que han conseguido establecer una relacion entre el rendimiento cognitivo y academico de los alumnos y sus niveles de condicion fisica. Los objetivos de esta investigacion son estudiar la correlacion existente entre el nivel de condicion fisica y la composicion corporal con el rendimiento academico, asi como analizar la correlacion entre dichas variables y la percepcion subjetiva del esfuerzo (RPE) por genero en alumnos de Educacion Primaria. Un total de 69 alumnos de Educacion Primaria participaron en el estudio (edad= 12,33±0,47 anos, 55,9% ninas y 44,1% ninos). La condicion fisica y la composicion corporal se evaluaron siguiendo los test de la ALPHA Fitness test Battery para ninos y adolescentes. El rendimiento academico se estudio mediante el promedio de notas de las asignaturas instrumentales de Educacion Primaria. La RPE se registro en las clases de EF y actividades fisicas escolares mediante el uso de la escala RPE de Borg (0-10). Se establecieron correlaciones significativas entre la RPE y el peso de los chicos (r= 0,406, p= 0.02) y las chicas (r= 0,643, p EnglishThere are studies in which it has been possible to establish a relationship between the cognitive and academic performance of students and their levels of physical condition.The objectives of this research are to study the correlation between the physical fitness level and body composition with the academic performance, as well as to analyze the correlation between such variables and the Rating of Perceived Exertion (RPE) of elementary school students by gender. A total of 69 primary school students participated in the study (age= 12.33±0.47 years, 55.9% girls and 44,1% boys). The physical fitness and body composition were evaluated according to the ALPHA Fitness test Battery for children and adolescents. The academic performance was studied by means of the average of notes of the instrumental subjects of primary education. The RPE was recorded in PE classes and school physical activities by using the Borg RPE scale (0-10).Significant correlations were established between the RPE and the weight of the boys (r= 0,406, p= 0.02) and girls (r= 0,643, p
