Heart Rate
The workload signal — how hard your system is working to meet demand.
Why it matters
- Helps interpret overall strain across hypoxic and recovery phases
- Adds context to oxygen response (SpO₂ without HR can be misleading)
- Supports consistency and progression across sessions
In-session: HR trends help validate that the session is producing meaningful physiological load.
In reports: Average HR, peak HR, HR by interval, recovery pattern.
