# Scaling Equipment Effect on Technical-Tactical Actions in U-13 Basketball Players: A Maturity Study
## 4 Discussion  
Scientific evidence needs to be provided to sports federations in a concrete proposal to modify under-13 basketball. Specifically, the aim of this study was to analyse the lower basket height, reducing the distance of the three-point line, and adding a four-point line. \begin{table}

Table 4: Mean values and standard deviation of Ball Handler Shooting Performance, according to maturating timing and tournament. In the Modified Tournament, the players experienced different game situations typical of integral learning and the non-linear pedagogical approach [2; 12; 26]: (a) greater participation of the players in technical-tactical actions; (b) greater variability of technical-tactical actions; (c) more offensive than defensive actions; and (d) a greater efficiency of the finishing actions, despite a higher level of opposition. Regarding the participation of the players in technical-tactical actions, the results showed a significant increase in the number of balls obtained in the modified tournament. This increase is related to a greater number of passes, possibly because, as there is a four-point line and the three-point line is closer to the basket, the defence players should be closer to the offence players, and this consequently increases defensive mismatches, to enable the player to find an effective place to shoot. The increase in the number of passes provokes the intervention of more players during the game, thus increasing participation and collective play [27].
