摘要：Antecedentes: la prevalencia de obesidad infantil ha aumentado considerablemente en Chile y el mundo, presentando asociación negativa con el rendimiento físico. Objetivo: el propósito del estudio fue determinar el rendimiento físico en escolares y asociarlos a los niveles de sobrepeso, obesidad y riesgo cardiometabólico. Material y métodos: 342 escolares, entre 11 y 16 años de edad, participaron del estudio, un 44,2% correspondió a mujeres y un 55,8% a hombres. Se evaluaron las siguientes variables: peso, índice de masa corporal, porcentaje de masa grasa, contorno cintura, razón cintura estatura, test de salto largo, test de abdominales, test de flexo-extensiones de brazo, test de Cafra y test de Navette. Resultados: se observó que los escolares con sobrepeso y obesidad (48,3%) mostraron un incremento significativo en las medidas antropométricas, así como una disminución en todas las variables que determinan rendimiento físico. En el análisis de los Test de Cafra y Navette, se observó que la presencia de la alteración de al menos uno de ellos se asoció con riesgo cardiometabólico (OR = 9,29, p
其他摘要：Background: The prevalence of childhood obesity has increased considerably in Chile and the world, presenting negative association with the physical performance. Objective: The purpose of this study was to determine the physical performance in students and associate them with levels of overweight, obesity and cardiometabolic risk. Material and methods: 342 students, between 11 and 16 year old, took part of the study, 44.2 % corresponded to women and 55.8 % to men. The following variables were evaluated: weight, body mass index, percentage of fat mass, contour waist, reason waist height, Test of long jump, Test of abdominal, Test of Flexo-extensions of arm, Test of Cafra and Test of Navette. Results: It was observed that the students with excess weight and obesity (48.3%) showed a significant increase in the anthropometric measurements, as well as a decrease in all the variables that determine physical performance. In the analysis of the Test of Cafra and Navette, it was observed that the presence of the alteration of at least one of them was associated with cardiometabolic risk (OR = 9.29, p > 0.001), while the presence of the alteration of the two tests is strongly associated with the presence of overweight and obesity (OR = 11.8, p = 0.003) and with cardiometabolic risk (OR = 30.1, p > 0.001). Conclusion: The students with obesity showed decrease in all variables that determined the physical performance and was the alteration cardio respiratory fitness measure through the test of Cafra and Navette that presented the greatest and significantly association with the overweight, obesity and cardiometabolic risk.
