Competition Stress Study

Neural Stability Under Competitive Pressure

This study examined the neural differences between training and competition performance in elite-level pistol shooters, in collaboration with Blekinge Institute of Technology and Ronneby Pistol Club.
Two experienced shooters with international competition backgrounds participated. Each completed structured training shots followed by a simulated competition under time pressure.

Objective

The purpose of the study was to investigate:

  • Whether neural patterns differ between training and competition
  • How stress influences performance stability
  • Whether measurable neural markers explain performance changes under pressure

Part 1: Performance-Related Neural Activity

Analysis of beta activity in the visual cortex (O1 and O2) revealed a strong positive relationship between neural intensity and shot score during competition.
In simple terms:

Higher visually driven beta activation was associated with higher scoring shots.
Importantly, both shooters demonstrated the same underlying performance mechanism:

  • Visual cortical activity strongly correlated with shot precision
  • Relevant frequency bands (theta/beta depending on phase) were consistent across individuals
This suggests a shared neural performance principle in precision shooting.

Part 2: Stress Regulation and Neural Stability

A second analysis examined stress regulation using the Alpha/Beta ratio — a well-established index of neural balance between:

  • Alpha → regulation, recovery, stability
  • Beta → activation, vigilance, pressure
The results revealed a critical difference between the shooters:

Shooter 1 – Stress Resilient

  • Maintained a relatively high and stable Alpha/Beta ratio
  • Demonstrated neural stability under pressure
  • Showed minimal performance decline in competition

Shooter 2 – Stress Sensitive

  • Displayed significant drops and fluctuations in Alpha/Beta ratio
  • Showed greater neural variability under pressure
  • Experienced clearer performance decline during competition

Interpretation

Both shooters rely on the same neural mechanism for high-quality performance — strong visual activation linked to precision.

However, they differ significantly in their ability to regulate stress and maintain neural stability under time pressure.

Stress does not create a new performance mechanism.
It disrupts an existing one.

The key difference lies in how effectively the nervous system preserves balance between activation and regulation during competition.

Significance

This study demonstrates:

  • A measurable, shared neural mechanism of performance
  • Clear individual differences in stress regulation
  • A direct relationship between neural stability and competitive outcome
The findings are consistent with modern performance neuroscience, showing that competitive success depends not only on technical skill, but on neural resilience under pressure.
