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.

The aim of the present study was to examine the effect of physical fatigue on special skill of basketball shooting in expert players. 10 male basketball players (mean age 24.9 years and average sport experience 10.5 years) voluntarily participated in this study. In the pretest, players performed 150 shoots from 5 distances: 3.35, 3.96, 4.57, 5.18 & 5.79 meters from the basket (each location 30 shoots). In the posttest, RAST test was used to create fatigue. Players completely performed RAST once before performance in any distance, and then immediately performed their 30 shoots. The results of linear regression and one-sample t test showed a significant difference between actual and predicted performances of players at the penalty point in both pretest and posttest supporting the special skill effect.Results of dependent t test also revealed a significant difference in performance of players between in penalty point and the farthest point in pretest and posttest. Finings of this study suggested that players showed special skill in the penalty point and physical fatigue had no significant effect on the performance of players and did not reduce the quality of their performance at that point.

The aim of the present study was to investigate the relationship between personality traits and incidence of injury in Iranian elite wrestlers. 60Iranian elite athletes participated in this study. Data were collected with injury report form and NEO personality questionnaire. The descriptive statistics and Pearson correlation coefficient at a significance level of 95% were used for data analysis.Results showed that all of the wrestlers suffered from at least two injuries during one season. The results showed a significant relationshipbetween personality traits includingneuroticism (P≤0.005), extraversion (P≤0.003), openness to experience (P≤0.047), agreeableness (P≤0.0001) and conscientiousness (P≤0.0001).Overall, findings indicated that personality traits such as low neuroticism, high extraversion, low openness to experience, high agreeableness and highconscientiousness helped elite athletes to better handle stressful situations in sports andto confront harmful psychological factors such as stress and anxiety through enhancing self-confidence and finally decrease injury incidence. Thus, officials, coaches, physicians and sport psychologists are recommended to plan to evaluate elite athletes' personality traits so that injury incidence can reduce and be prevented through a selection of those athletes with suitable personality traits.

Profile of mood states tests show that the players who are injured are affected psychologically as well. In cases of severer injuries, loss of mental health and tendency to depression are not uncommon. The aim of this study was to evaluate the effect of sport injuries on profile of mood states of Tehran Persepolis team soccer players. For this purpose, 54 players from Tehran Persepolis team (adults and youth) participated in this study. Research data were collected by the team physician with POMS questionnaire before and after the players' injuries. The descriptive statistics and dependent t test at a significance level of 95% were used for data analysis. Results indicated that all players experienced at least one injury during one season (2012- 2013). The findings also indicated that their profile of mood states was similar to Morgan' profile before their injury while this profile was reverse after their injury. There was a significant difference in players' profile of mood states before and after the injury (P=0.0001). Findings indicated that the mean of players' POMS changed after the injury. Also, their tension, depression, anger, fatigue and confusion increased while their vigor decreased.
