Purpose The present study aimed to investigate the efficacy of a QE-training duration on improving the performance and accuracy of basketball three-point shot and determined whether such training protected against attentional disruptions associated with performing under pressure. Methods Eighteen expert male basketball players wore a mobile eye tracker to assess their quite eye (QE) duration when performing three-point shots carried out over 6 days without defensive pressure. They first participated in pre-test and were randomly allocated into a quiet eye (QE)-trained and control group. Both groups participated in video feedback of their gaze behavior and on-court training sessions and only the QE-trained group received additional instructions related to maintaining a longer QE duration. Their accuracy and gaze behaviors were recorded through post and pressure tests. Results The QE-trained group performed significantly better and had longer total, early and late QE duration through the phase of tests compared to the control group. Conclusion These results provide support for the efficacy of QE training focused on using visual information until the ball is released in undefended conditions. Future research is needed to determine if the results also apply when the athlete is closely defended.
