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 the present study was to investigate the manipulation of senses and speed on the performance of bimanual dynamic coordination. Thus, 15 physical education students of Shahid Beheshti University with age range of 18-25 years performed in-phase and anti-phase patterns from slow to fast speed in five different sensory conditions. To investigate two motor patterns ANOVA with repeated measures (5 sensory conditions × 3 speeds) on each in-phase and anti-phase pattern. Bonferroni post hoc test was used to analyze their following effects. The dependent variable was error of relative phase. Results showed that increasing the speed of performance influenced the performance of the anti-phase pattern (P=0.001), but it did not influence the in-phase pattern (P=0.9). Sensory manipulation results indicated that proprioception and vision manipulation had an effect on the accuracy and the variability of performance of two relative phases of motor patterns (P=0.001), but audition manipulation did not affect these patterns (P=0.315). In addition, the highest mean of error of relative phase and standard deviation of error of relative phase were observed in proprioception manipulation (P=0.001). It can be expressed that the bimanual linear coordination task in this study was a proprioceptive dependent task.

The purpose of this study was to determine the relationship between perceived motivational climate and self – determination Judokas in Iranian pro league, which was carried out by a descriptive field method. The statistical population of this study comprised the entire Judokas of pro league in Iran. Statistical sample set of 126 Judokas of pro league in Iran.
In order to collect data, demographic questionnaire, perceived motivational climate in sport questionnaire – 2 (PMCSQ) and sport motivation scale (SMS), were used. In order to analyze of data dscriptive mthods were used and also on level of P<0.05 in order to determine the relationship a multiple variable regression was used. Research results showed that there is a significant relationship between perceived motivational climate and self – determination (P<0.05). Also, the findings showed that there is a significant relationship between performance climate and eccentric and intrinsic motivation (P<0.05) and there is signigicant relationship between Mastery climate and intrinsic motivation (P<0.05). but, there was no relationship between motivational climate and amotivation on the other (P>0.05). generally between perceived motivational climate is important and predicitve factor in athlete's self – determination.
