Summary
Athletes increasingly combine heat and altitude training for performance gains. Both stressors affect autonomic function, and HRV monitoring helps track acclimatization and prevent overreaching.
Methods
Review of combined heat and altitude training protocols
Key Findings
- Both heat and altitude stress autonomic system
- HRV helps monitor adaptation progress
- Metrics stabilize as acclimatization occurs
- Heat may provide similar hematological benefits to altitude
- Combined training increasingly common in elite sport
Limitations
Optimal protocols still being refined
What This Means for You
When training in challenging environments, use HRV to track acclimatization. Stable HRV values indicate adaptation is occurring. Don't push hard training until HRV normalizes.
