Abstract

We examined changes in brain rhythms in relation to optimal performance in self-paced sports. Eight studies met the inclusion/exclusion criteria, representing 153 participants and eight different sports. We found that (a) optimal performance is characterised by increased alpha (g = .62, p = .02) and theta (g = .74, p = .002) across the cortex; (b) during optimal performance the frontal lobe is more relaxed (higher alpha; g = 1.06, p = .18) and less busy (lower theta; g = .38, p = .08), in comparison to the other brain lobes; (c) for the same given task, experts' brains are more relaxed (higher alpha, g = .89, p = .34) and less busy (lower theta, g = .91, p = .54) than novices' brains. Theoretically, our findings suggest that neural efficiency, neural proficiency, and transient hypofrontality are likely complementary neural mechanisms that underpin optimal performance. In practice, neurofeedback training should teach athletes how to amplify and suppress their alpha and theta activity across the brain during all movement stages.
