The aim of this study was to analyse the type of training situations used in youth basketball practices. The sample includes 394 training tasks from an U12 team and 389 tasks from an U14 team. The variable game situation was analysed. A descriptive analysis of data from each of the teams and an inferential analysis utilising the Mann Whitney U and Kolmogorov-Smirnov tests were done. There was a predominance of 1-on-1, 2-on-2, and 3-on-3 situations in the U12 team´s training and 1-on-1 and 5-on-5 situations in the U14 team´s training. For U12, an evolution of situations ranging from simple to complex was seen. The results suggest that the U12 team’s tasks are typical of a comprehensive model based on a constructivist approach while the U14 team’s tasks come from a technical model.
