Effects of expertise in skill-oriented sports on postural control: An event-related potential study using dual-task...

Postural control is a fundamental aspect of motor skills and is crucial for achieving optimal performance in sports. However, previous studies mainly explored the postural control ability of athletes of skill-oriented sports (skilled athletes) under single postural control conditions, disregarding the processing characteristics of postural control in real sports scenarios. This research used the event-related potential (ERP) to investigate the postural control ability of skilled athletes during the action inhibition process by a dual-task paradigm. The study included 26 skilled athletes and 25 nonathletes who simultaneously completed a postural control task and a Go/Nogo task. The results showed that skilled athletes exhibited superior postural control performance in all three standing positions and higher N1 and P3 component amplitudes than nonathletes. The study illustrated that skilled athletes exhibit higher flexibility in allocating attentional resources to ensure optimal postural control and action inhibition performance. These findings suggest that skilled athletes possess a higher level of control automation in complex standing positions and more efficient and economical brain processing characteristics, which may contribute to their exceptional performance in sports.
