Análise da habilidade motora fundamental de saltar na horizontal em crianças obesas

Abstract

This research investigated if significant differences in the process and the product of the horizontal jump in function of the obesity exist. Ten obese children and ten not obese ones registered in the Municipal net of Education of the city of Itaqui-RS had participated of this study. For evaluation of the obesity the measures of corporal weight and stature, using themselves of scale and anthropometer had been collected. Later, the index of corporal mass was calculated (IMC) and was applied the test to jump in the horizontal line. For the analysis of the execution proceeding of the jump, an analytical matrix, based was used in the matrix of Gallahue & Ozmun10 (2005) and in the described developmental sequences for Haywood & Getchell9 (2004), which subdivided the jump in 5 phases of 3 movements each. The children had been categorized in each movement, in the following classification: inefficient or efficient. For the analysis of the product of the jump the best ones resulted in centimeters had been used. For the analysis of the data the tests for ratio of Primer had been used, of normality of the Shapiro-Wilk and Test t of “Student”. The results point with respect to (1) a higher considerable degree of inefficiency in the execution proceeding of the horizontal jump; (2) indices of inferior performance in the obese children; (3) superiority in the motor performance of the boys. However, this biological variable seems to contribute in significant way in the motor ability to jump in the horizontal line. The results evidence that the obesity in such a way acts in favorable way in the process how much in the execution product it horizontal jump, being able to come to reecho in the subsequent phases of the enrollment of these children in practical systematic sporting, extending still more the differences in relation to the not obese ones.
