Estudio longitudinal del estado nutricional y de la condición física de estudiantes de enseñanza media de un liceo municipal de Talca. Chile

Abstract

The objective of this research is to analyze the variables or nutritional status and physical condition of students from two high school grades (first and fourth year) during the years 2016, 2017 and 2018, to know their measurements upon entering and when leaving the establishment. For this, parameters of weight, height and waist circumference were evaluated in terms of nutritional status, while for physical condition; physical tests such as horizontal jump and elbow flexionextension were contemplated. The variables of weight and horizontal jumps underwent changes. The first had a constant increase during the years of study in the first year (p<0,068), which led to an increase in BMI (p<0,054) while the horizontal jump had a significant decrease in the fourth year (el cuatro año?) (p<0,004). This determines that the parameters of nutritional status and physical condition of the students evaluated suffered negative effects during this research.
