Summary
Overnight HRV monitoring effectively tracks allostatic load in military personnel during training. HRV shows sensitivity to acute stressors and recovers faster than subjective wellbeing measures.
Methods
15-day assessment in combat engineers with varied training phases
Key Findings
- Overnight HRV reflects workload and stress during training
- HRV sensitive to sleep deprivation and restriction
- HRV returns to baseline faster than subjective measures
- Useful for repeated measurement of allostatic load
- Can inform training periodization and recovery
Limitations
Individual responses vary, context-dependent
What This Means for You
For tactical professionals, overnight HRV provides objective recovery data that may detect stress before subjective symptoms appear. Use HRV trends to optimize training loads and recovery.
