The QET‐based intervention for the QET group consisted in performing the targeting tasks (Table Targeting tasks and their modifications for the quiet eye training–based intervention.The split‐screen video of the throwing bolas task (the motor video on left half and the gaze video on right half of screen).The QET consisted of five training sessions, one session per week, with 7 days between two consecutive sessions. The training sessions always took place at the school attended by the given participant, in a sufficiently large room and under the guidance of a trained postgraduate instructor. At each training session, one targeting task and modifications thereof were practiced. The sessions were run according to the QET protocol for a throwing task described by Miles et al. (The participant was allowed a short break at any step during the training protocol if needed. After a short 3–4 min break, the participant performed various modifications of the task with the use of the six‐step training protocol presented above. The total time of each lesson was 35 min. The same training protocol was used for all lessons. The sessions took place every week on the same day ± 1 day.
