Formatos Competitivos en Fútbol Sub-12. Un Análisis desde el Punto de Vista Táctico, Condicional y del Compromiso Deportivo del Joven Futbolista

In this study, we analyzed the technical-tactical and conditional differences between of 7-a-side soccer and 8-a-side soccer as competition formats, as well as the subjects’ current and future sport commitment. 280 under-12 players participated in the tactical and conditional tests, 149 of which participated in the sports commitment tests. For the technical-tactical and conditional tests, WIMU devices were used. These devices include different sensors, as GPS, accelerometer and heart rate. For the sports engagement tests players completed a questionnaire. From the tactical point of view, findings show that there are higher areas of play and relationships, and interactions between players / teams with greater distances, in the 8-a-side soccer format. From the conditional point of view, 7-a-side soccer is somewhat more demanding than 8-a-side soccer, since it presents more prolonged and more intense efforts. Both formats have shown that we are facing an intermittent sports practice, where most of their efforts are made at medium or high intensity, with physical (m•min-1) and physiological (% HRmax) values that approximate the adult format of 11-a-side soccer. From the point of view of sports commitment, the higher players’ competition level is, the higher level of commitment players have.
