4Objectives. The ability to perform a context-free 3-dimensional multiple object 5 tracking (3D-MOT) task has been highly related to athletic performance. In the 6 present study, we assessed the transferability of a perceptual-cognitive 3D-MOT 7 training from a laboratory setting to a soccer field, a sport in which the capacity to 8 correctly read the dynamic visual scene is a prerequisite to performance. Design. 9Throughout pre-and post-training sessions, we looked at three essential skills 10 (passing, dribbling, shooting) that are used to gain the upper hand over the 11 opponent. Method. We recorded decision-making accuracy during small-sided 12 games in university-level soccer players (n=23) before and after a training 13 protocol. Experimental (n=9) and active control (n=7) groups were respectively 14 trained during 10 sessions of 3D-MOT or 3D soccer videos. A passive control 15 group (n=7) did not received any particular training or instructions. Results. 16 Decision-making accuracy in passing, but not in dribbling and shooting, between 17 pre-and post-sessions was superior for the 3D-MOT trained group compared to 18 control groups. This result was correlated with the players' subjective decision-19 making accuracy, rated after pre-and post-sessions through a visual analogue 20 scale questionnaire. Conclusions. To our knowledge, this study represents the 21 first evidence in which a non-contextual, perceptual-cognitive training exercise 22 has a transfer effect onto the field in athletes.
