Alteraciones en el rendimiento físico de escolares: Los Test Cafra y Navette y su asociación con la obesidad y riesgo cardiometabólico

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.
