immediate feedback concerning brain activity on autotelic engagement attention and the performance of athletes’ minds.

Material and methods: the experimental group (25 subjects) underwent twenty neurofeedback-EEG training sessions (in the relaxation armchair) and athletic training for four months (every 7 days). The control group (25 subjects) underwent athletic training sessions. Before and after the four months of neurofeedback-EEG training sessions, the athletes were evaluated using an involvement questionnaire and Kraepelin’s work curve test.

Results: the results of the analysis showed that changes in autotelic engagement were observed with an improvement in the performance of the mind (p < 0.01), which points to increased speed and mental work speed and efficiency. Among three measures of performance, we observed a significant correlation between the total number of addition operations in the test with autotelic experience (r = 0.769).

Conclusions: neurofeedback-EEG training opens up new opportunities for improvement in the performance of athletes’ minds.
