This study examined brain activity patterns in 16 skilled football players during penalty kick preparation, finding that successful kicks were associated with lower alpha-band coherence between specific brain regions compared to unsuccessful kicks. Specifically, reduced connectivity between frontal-temporal regions (Fz-T7) throughout preparation and between central-right temporal regions (Cz-T8) immediately before kick execution characterized successful performance. The findings suggest that efficient motor performance depends on selective reductions in brain connectivity rather than generalized decreases, possibly reflecting reduced interference from verbal-analytical and visuospatial processing during skilled movement execution.
Why it matters
These results could inform training approaches for athletes by identifying neural efficiency markers associated with successful performance under pressure. The findings may also have applications beyond sports, potentially helping optimize motor rehabilitation protocols and understanding how expert performers manage cognitive-motor interference during complex actions.
Understand the Science
IntroductionSuccessful motor performance may depend on the efficient coordination of cognitive and motor processes during movement preparation. Although previous electroencephalographic studies have linked alpha-band (8–13 Hz) coherence with performance in upper-limb precision tasks, little is known about cortico-cortical communication preceding successful lower-limb actions.MethodsSixteen skilled football players performed penalty kicks under an individualized task-difficulty condition. EEG coherence was calculated for eight electrode pairs connecting the left and right temporal regions with frontal, central, parietal, and occipital midline sites. Coherence was examined during an early preparation period from −2,000 to −1,000 ms and a late preparation period from −1,000 to 0 ms before kick initiation.ResultsSuccessful kicks showed significantly lower Fz–T7 coherence than unsuccessful kicks across both preparation periods. Successful kicks also exhibited lower Cz–T8 coherence during the late preparation period.DiscussionLower Fz–T7 coherence may reflect reduced interaction between verbal–analytical processing and motor planning, whereas lower Cz–T8 coherence may indicate reduced coupling between visuospatial processing and motor-control processes immediately before kick initiation. These findings extend previous evidence from upper-limb precision tasks to football penalty kicking and support the psychomotor efficiency hypothesis. Successful kicking appears to be characterized by selective and time-dependent reductions in functional coupling rather than a general decrease in cortical connectivity.
