Perfil morfológico, físico/motor, psicológico e maturacional de atletas mirins de atletismo

Abstract

The Knowledge of sports profile related to anthropometric, physical, psychological and maturity variables is of great importance for coaches have assessment parameters and development of young athletes throughout the process of long-term training. It is known that athletes from different sports should be evaluated By specific tests for the sport and in relation to track and field no studies that carried out an extensive characterization of young athletes belonging to the Mirim category were found. Thus, the objectives of study were to describe the profile and prepare a table of percentile of morphological, psychological, physical / motor, and maturity of specific evidence of male junior track and field athletes variables, evaluating the effect of somatic maturity in those variables and the association evaluation of the coach regarding the potential performance of athletes with year of birth, maturity stage and won competitions. 94 young track and field athletes of 8 teams, belonging to mirim category were evaluated. On the first day, was performed, anamnesis, anthropometric (weight, height, sitting height, arm span and skinfolds), applicated motivation scale for sport, Running-based Anaerobic Sprint Test (RAST) test was performed the shot put, long jump, 800 m run and questionnaire to evaluate the sports coach characteristics of each athlete. On the second day, we evaluated the flexibility (sit and reach), vertical jump (Jump Counter Movement and Squat Jump), Speed (60m run test) and maximal aerobic speed (Test Léger-Boucher). After testing, a short questionnaire was sent to the biological parents so that they selfreported the respective statures. The main findings were: defining the characteristics of young track and field athletes according to the variables analyzed, the somatic maturity influences the behavior of the anthropometric variables (weight, height, leg length), physical / motor (squat jump and countermovement jump), specific abilities (running 60 m, shot put and long jump), but on the other side, does not influence maximal aerobic speed obtained in Léger-Boucher test, the percentage of fatigue in RAST and run time of 800 m; evaluating the performance potential of athletes, taken by coach, is not associated with the year of birth or the maturity stage of the athletes, but is influenced by the number of victories in competitions. It Can be concluded that young track and field athletes, belonging to the Mirim category, has specific characteristics in terms of the variables analyzed, the maturity an intervening factor in the results. There is no association between the athlethes performance, measured by the coach, with birth year and maturity stage. On the other hand, there is association between occurrence of victory and competitions.
