Introduction: This study aimed to determine the effects of skilled people’s EEG-Based neurofeedback training on learning of the rifle shooting skills in novices.Methods: This applied study was a semi-experimental research with a pretest-posttest control group design. Thirty novice athletes (mean age: 20±1.509 years) voluntarily participated in this study and were assigned into three homogenous groups including Beta/Theta Neurofeedback, Neurofeedback based on the brain pattern of skilled rifle shooters (decreasing the Theta activity in Fz and F4 area, and increasing the low and high Alpha at the P3 and P7 area, and Control groups according to pretest scores. The acquisition phase consisted of 6 sessions. The control group only did physical exercise during the sessions. 48 hours after the last acquisition session, a retention test was conducted followed by a transfer test by a non-dominant hand to grab the weapon.Results: The results showed that the group with neurofeedback based on the brain patterns of skilled rifle shooters was significantly better than the other two groups in all sessions. In the retention test the group with neurofeedback based on the brain patterns of skilled rifle shooters significantly performed better than the other two groups and the Beta/Theta Neurofeedback group had better performance compared with the Control group. In the transfer test, both neurofeedback groups performed better than the Control group, but there was no significant difference between the two neurofeedback groups.Conclusion: Future research can accelerate the progress and reach the peak shooting performance for novices by correcting neurofeedback protocols according to the brain and the expertise relationship.

Successful anticipation is a key factor for success in saving soccer penalty kick for goalkeepers and introducing optimal interventions to enhance this ability can be useful for improving the level of performance. The aim of the present study was to examine the effect of quiet eye training on anticipation of penalty kick by expert goalkeepers and their gaze behaviors during this anticipation. Participants were 20 expert goalkeepers working in Tehran pro league matches who were randomly assigned to training and placebo groups and passed tests and training interventions. Gaze data were registered using Pupil eye tracker and penalty kick anticipation was recorded using temporal occlusion paradigm. 30 videos of real penalty kicks by expert soccer players were recorded and ball-foot contact moments were occluded so that goalkeepers could anticipate the direction of ball kicking in those videos. Results of 2*4 mixed ANOVA showed that despite of homogeneity of training and placebo groups in pretest (P>0.05), training group had advantage in other phases and this advantage was maintained under pressure (P<0.05). The training enhanced successful anticipation and changed gaze behaviors proportional to successful anticipation and these changes were sustained during 72 hours of retention and transfer test under pressure. Training interventions based on quiet eye can be used as a training package along with physical training and skills of soccer goalkeepers and therefore help them to improve perceptual capabilities and to optimally use visual signs.
