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.

Concentration, or the ability to focus on the task at hand while ignoring distractions, is a vital determinant of successful performance in sport. The main aim of this study was to examine the effects of neurofeedback and mindfulness interventions on visual continuous performance in young athletes. 45 soccer players (age range of 16 - 20 years) who attended the National Leagues in 2017 were assigned to three groups (alpha/theta neurofeedback intervention, mindfulness intervention, and control). Athletes in neurofeedback group received 12 sessions (2 sessions per week, 30 minutes per session) of neurofeedback training with high alpha/low theta protocol and athletes in mindfulness group received 12 sessions (2 sessions per week, 30 minutes per session) of mindfulness meditation. Before and after interventions, visual continuous performance test was used. The control group received no interventions. The results of mixed ANOVA and ANOVA with repeated measures at significance level of 0.05 showed a significant improvement in all dimensions of visual continuous performance test (omission error, commission error, and reaction time) in neurofeedback and mindfulness groups compared with the control group. Also, the results indicated no significant differences between neurofeedback and mindfulness groups in the dimensions of the visual continuous performance test. The results of this study indicated the effectiveness of alpha/theta neurofeedback training and mindfulness training as visual continuous performance improvement training compared with the control group in young athletes.

The employment of neurofeedback is growing rapidly in sport performance enhancement. The aim of this study was to investigate the effect of neurofeedback training on motor performance and conscious motor processing of skilled dart players. The subjects were 20 male skilled dart players. The research was conducted in five phases: pretest, neurofeedback training, posttest 1, under pressure test and posttest 2. Neurofeedback training consisted of prevention training of the alpha frequency band (8 to 12 Hz) in F4. To analyze data, descriptive statistics and mixed ANOVA were used. Results indicated that the amounts of conscious motor processing for neurofeedback training group decreased in posttest 1 (P=0.001) and under pressure test (P=0.001) but this reduction was not observed in the control group (P=0.83). The dart throwing points for neurofeedback training group and control group in the posttest 1 increased compared with the pertest (P=0.001), but only neurofeedback group (P=0.001) was able to preserve this increase in the under pressure test. The findings indicated an effect among neurofeedback training, conscious motor processing and sport performance. In other words, the neurofeedback training leads to the desired motor performance and creates automatic sense in the athlete by reducing the conscious motor processing.

The aim of this study was to investigate the effect of neurofeedback training on sleep quality and psychological skills of athletes with psychophysiological approach. The research method was semi-experimental and application with pretest and posttest design and a control group. 31 athletes who were members of a sport team gained the criteria to enter the study. They were randomly assigned to experimental and control groups and the experimental group received neurofeedback treatment. The neurofeedback training lasted 3 sessions a week, 45 min. each session for 2 months. This protocol was performed in a bipolar manner at C4-CZ points. Pittsburgh Sleep Quality Index (PSQI) was used to extract sleep quality profile and OMSAT-3 and Elisa method were used to assess psychophysiological stress of participants. Covariance analysis and dependent t test were used to analyze the data. The results suggested that neurofeedback training can influence to balance stress and to improve sleep quality of athletes which greatly affects their performance.

This study compared the effects of neurofeedback and physical practices on performance and retention of dart throwing skill. 24 subjects were selected by convenience sampling method from female physical education students of Urmia University who were all right-handed with no history of neurofeedback training and dart throwing. They were divided to three groups: physical practice, neurofeedback and control (each group 8 subjects). The practice protocol was conducted 3 sessions a week for 5 weeks and then posttest was administered. Retention test was conducted 5 days after the last practice session. The data were analyzed by two-way ANOVA with repeated measures of factor test, one-way variance, and post hoc tests. The results of two-way analysis of variance with repeated measures indicated that although the participants progressed in both neurofeedback and physical practices in the performance phase, there was no significant difference between the experimental groups at this stage. In addition, the main effect of the test phases was significant, but the main effect of group and interaction of the test phases and group were not statistically significant. That is to say the difference of the effects of neurofeedback and physical practices on performance and retention of dart skill was not significant. These results clarified the effect of neurofeedback and physical practices; therefore, they need to be used simultaneously.
