Neurofeedback Intervention and Athletic Performance Optimization; Systematically review, metaanalysis and proposing a theoretical model

The present study was conducted to achieve the effect of neurofeedback intervention on athletes' performance and investigate other factors affecting its effectiveness, and proposing a theoretical model. The present study is a systematic review and meta-analysis research model. In the first phase of the study, all Persian and English studies on the effectiveness of neurofeedback intervention on athletes' performance were systematically reviewed, and among them, studies with meta-analysis criteria were reviewed by Meta-Analysis Basics and Applications. Out of 758 studies, 28 studies were meta-analyzed. In the second stage, a specific intervention model for athletes was developed based on various components affecting performance. The results showed the effect size (ES) of Neurofeedback Intervention is large according to Cohen's table. Therefore, neurofeedback intervention improves the performance of athletes. In the second stage, the factors affecting the performance of athletes following neurofeedback intervention were developed in the form of a specific intervention model for athletes. The findings of this meta-analysis showed a “large” ES for neurofeedback intervention on Athletic Performance Optimization. And can confirm the opinion of researchers about the importance of neurofeedback intervention in optimizing the performance of athletes.
