Faridnia et al. (2012) showed that Sport Performance-Neurofeedback reduced anxiety in female swimmers, specifically reducing competitive anxiety. Mikicin et al. (2015) found that Sport Performance-Neurofeedback improved cognitive function (swimming, fencing, judo) and visual attention response, as well as the Kraepelin working curve, in 35 college athletes.

If an athlete feels very excited and under pressure on match day, they exhibit excessive beta activity due to anxiety. Beta waves are intense attention waves. Although beta waves are attention waves, excessive beta wave production in the brain creates anxiety, making the person tense and aggressive, leading to poor decisions. When we teach the brain to reduce excess beta waves, the same player can approach the match more calmly and lead themselves or their team to victory with the right decisions.
