Cortical processing during table tennis - an fNIRS study in experts and novices

Area of Science:

• Neuroscience
• Sports Science
• Motor Control

Background:

• Athletic performance is influenced by numerous factors, yet the brain's specific contribution remains underexplored.
• Understanding neural processing differences between experts and novices is crucial for optimizing training and performance.
• Table tennis offers a complex motor task ideal for investigating expertise-related brain adaptations.

Purpose of the Study:

• To investigate modulatory differences in brain processing related to expertise and task complexity in table tennis.
• To examine the role of specific brain regions, including motor areas, in table tennis performance.
• To correlate neural activation patterns with behavioral performance metrics.

Main Methods:

• Functional near-infrared spectroscopy (fNIRS) was used to record hemodynamic responses during table tennis tasks.
• 28 participants (14 experts, 14 novices) performed standardized table tennis strokes.
• Analysis focused on neuronal activation in motor areas (M1, PMC, IPC) and its correlation with performance.

Main Results:

• Both experts and novices exhibited localized activation in motor areas (M1, PMC, IPC).
• Experts performed more strokes and showed significantly higher hemodynamic responses in motor areas compared to novices.
• A positive correlation was found between the number of strokes and hemodynamic response magnitudes in M1, PMC, and IPC.

Conclusions:

• Table tennis performance is associated with extensive activation of M1, PMC, and IPC.
• Increased activation in these motor areas in experts suggests enhanced neural processing related to movement speed, frequency, or task familiarity.
• These findings highlight the brain's critical role in expert-level athletic performance.
