Physical fitness, rating perceived exertion and academic performance in primary school

Existen estudios que han conseguido establecer una relación entre el rendimiento cognitivo y académico de los alumnos y sus niveles de condición física. Los objetivos de esta investigación son estudiar la correlación existente entre el nivel de condición física y la composición corporal con el rendimiento académico, así como analizar la correlación entre dichas variables y la percepción subjetiva del esfuerzo (RPE) por género en alumnos de Educación Primaria. Un total de 69 alumnos de Educación Primaria participaron en el estudio (edad= 12,33±0,47 años, 55,9% niñas y 44,1% niños). La condición física y la composición corporal se evaluaron siguiendo los test de la ALPHA Fitness test Battery para niños y adolescentes. El rendimiento académico se estudió mediante el promedio de notas de las asignaturas instrumentales de Educación Primaria. La RPE se registró en las clases de EF y actividades físicas 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< 0.001) y también con respecto al IMC, chicos (r= 0,508, p= 0.004), chicas (r= 0,621, p< 0.001). Existió una correlación negativa significativa entre el test de la Course Navette y la RPE en el caso de los niños (r= -0,633, p< 0.001) y de las niñas (r= -0,452, p= 0.004). La RPE se correlacionó significativamente con los palieres del test de Course Navette (correlación inversa) y las variables antropométricas, como son el peso y el IMC.There 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< 0.001) and also with respect to the BMI, boys (r= 0,508, p= 0.004), girls (r= 0,621, p< 0.001). There was a significant negative correlation between the Course Navette test and the RPE in the case of boys (r= -0,633, p< 0.001) and girls (r= -0,452, p= 0.004). The RPE correlated significantly with the stages of the Course Navette test (inverse correlation) and with the body composition variables, such as weight and BMI

O1-4 Validation of questions to assess the mode of commuting to/from school for children according to their parents: the PACO study

Background The active commuting to school behaviour is an opportunity to increase the physical activity levels. The most frequent used tool to assess the mode of commuting to school is self-reporting by children or by their parents. However, there is a lack of information about the validity between both, children and parents. So, the purpose is to validate the questions of mode of commuting to go and come back from school of children according to their parents'. Method A total of 611 parents (mean age: 43.28±6.25 years old) and their children (mean age: 11.44±2.77 years old) from Granada (Spain) completed a family (mode of commuting of children reported by parents as part of the Family PACO questionnaire) and a student questionnaire validated (Chillon et al., 2017) (mode and frequency of commuting to and from school questionnaire), respectively, in two measurement points. The questions from the ‘Family PACO questionnaire' are: “How does your child usually go to school?” and “How does your child usually come back?”; and the questions from the ‘mode and frequency of commuting to and from school questionnaire' are: “How do you usually go to school?” and “How do you usually go from school?”. The validation between parents and childreńs questions was analysed using Kappa and Spearman correlation coefficients. The results of the kappa are considered as: poor agreement (0-0.20), acceptable agreement (0.21-0.40), moderate agreement (0.41-0.60), substantial agreement / good (0.61-0.80) and almost perfect / very good agreement (0.81-1.00) (Landis & Koch, 1977). The Spearman correlations coefficients were interpreted as low (> 0.30), moderate (0.30-0.50), and high (> 0.50) (Van Dyck, Cardon, Deforche, & De Bourdeaudhuij, 2015). Results The validity of questions from both questionnaires about mode of commuting presented high coefficients of validation (Kappa coefficient; 0.865 to school and 0.839 from school and Spearman correlation; rho=0.882 to school and rho=0.860 from school). Conclusion The questions about the mode of commuting to/from school from the ‘Family PACO questionnaire’ are valid method. Therefore, the use of the questions would be recommended to assess children's mode of commuting
