Efeitos de um programa de iniciação esportiva sobre o desempenho tático-técnico e a coordenação motora no handebol

Abstract

The study analyzed the effects of a handball teaching program, based on the methodological proposal of the Iniciação Esportiva Universal, in motor coordination and tactical-technical performance of schoolchildren in age differences. The sample consisted of 135 students divided into four groups: Experimental group 1- EG1 – (n=33; 10.7±0.47) and control group 1 – CG1 (n=30; 10.73±0.45); Experimental group 2 - EG2 (n=37; 12.65±0.48); and control group 2 - CG2 (n=35; 12.8±0.41). The instructional protocol resulted in the didactic treatment of the content applied longitudinally, in a period of 43 weeks, with 38 sessions of classes. The dependent variables were measured in five moments (pre-test 1, post-test1, retention 1/pre-test 2, post-test2 and retention 2). A demographic questionnaire was applied, and the class sessions were filmed and later categorized. For the evaluation of dependent variables, the following instruments were used: Motor Coordination Test with Ball, Declarative Tactical Knowledge Test in handball, Tactical Procedural Knowledge Test and Game Performance Assessment Instrument. After analyzing the normality of the data by the Shapiro Wilk test, descriptive statistics (median and interquartile interval) and inferential statistics (Wilcoxon test, Mann-Whitney, Chi-square) were used. The results reported that both experimental groups (10-12 years and 12-14 years) showed significant differences for the variables of motor coordination, declarative and procedural tactical knowledge and in the performance of the game, considering the effect of time. Both sexes, in the experimental groups, presented effect sizes between medium and large after the application of the teaching program in the variables analyzed. t is concluded that the IEU teaching model applied to handball was able to contribute to the development of motor coordination and knowledge, declarative and procedural, of students in different age groups.
