Relationship between heart rate variability and cognitive function during threat of shock
Why the study?
Does resting heart rate variability predict cognitive function during threat of shock in male navy personnel?
Population
65 male participants from the Royal Norwegian Navy
Comparison
Threat of shock condition vs Non-threat condition
Design
RCT, Randomly assigned into non-threat and threat groups

Implication
HRV screening may aid resilience assessment in high-stress roles; extends RCT evidence on autonomic predictors of cognitive performance under threat.

P
Population
65 male participants from the Royal Norwegian Navy
I
Intervention
Threat of shock condition
C
Comparator
Non-threat condition
O
Outcome
Cognitive functions measured by a Continuous Performance Task and a Working Memory Task
Higher resting heart rate variability is associated with better cognitive performance and stress tolerance, independent of environmental threat.
