Enhanced response inhibition in experienced fencers

Area of Science:

• Neuroscience
• Cognitive Psychology
• Sports Science

Background:

• Response inhibition is a critical executive function.
• Individuals with fencing expertise demonstrate enhanced behavioral performance in response inhibition tasks.
• The neurophysiological underpinnings of this advantage are not fully understood.

Purpose of the Study:

• To investigate the electrophysiological basis of superior response inhibition in experienced fencers.
• To compare brain activity during response inhibition between fencers and non-fencers using the Go/Nogo task.

Main Methods:

• Utilized the Go/Nogo task to assess response inhibition.
• Measured behavioral performance and electrophysiological responses (EEG).
• Conducted single-trial analysis to examine neural processing.

Main Results:

• Fencers exhibited behavioral and electrophysiological advantages in response inhibition.
• Superior inhibition in fencers was linked to enhanced Nogo-N2 and reduced Nogo-P3 components.
• Nogo-N2 differences were attributed to lower latency variability, while Nogo-P3 differences suggested reduced neural activity in fencers.

Conclusions:

• Distinct neurophysiological indexes (Nogo-N2 and Nogo-P3) differentiate executive function in fencers.
• These markers can guide the assessment and monitoring of executive function and training progress in fencers.
