Alpha Neurofeedback Training in Elite Soccer Players Trained in Groups

Area of Science:

• Sports Science
• Neuroscience
• Human Performance

Background:

• Neurofeedback training is a recognized method for enhancing athletic performance.
• Traditionally, neurofeedback sessions are conducted individually.
• The feasibility of group-based neurofeedback in sports settings remains largely unexplored.

Purpose of the Study:

• To investigate the efficacy and feasibility of group neurofeedback training for athletes.
• To assess the impact of group neurofeedback on electroencephalogram (EEG) activity, cognitive performance, and well-being.
• To explore a scalable approach for neurofeedback application in team sports.

Main Methods:

• Forty-one national-level football players participated in group neurofeedback training sessions (up to 13 athletes simultaneously) using wearable EEG devices.
• A music-based neurofeedback protocol targeted the brain's alpha (8-12 Hz) and beta (13-30 Hz) activity.
• Training involved alternating neurofeedback periods with cognitive tasks, employing a crossover design.

Main Results:

• Good quality EEG measurements were obtained in a group setting, despite slightly higher data loss.
• A 34% increase in training-associated alpha activity was observed.
• Significant improvements were noted in task switching, mental rotation performance, sleep duration, and self-reported measures of control and flow.

Conclusions:

• Group neurofeedback training is a feasible and effective method for athletes, even in a team sport context.
• This approach offers a scalable solution for implementing neurofeedback in team settings.
• The findings suggest neurofeedback can enhance cognitive functions, performance, and overall well-being in athletes.
