PPG is a tool used to analyze the autonomic nervous system.
This test evaluates the balance between stress and recovery systems and measures HRV (heart rate variability), a key indicator of cardiovascular wellbeing.
Heart‑rate variability is an important marker of overall health. By assessing it, we can implement targeted prevention strategies and reduce the risk of future conditions.
The test evaluates:
- HRV – heart rate variability, a measure of cardiac wellbeing
- Balance between stress and recovery systems
- Acute and chronic stress levels
- Training‑load monitoring
- Overreaching and overtraining conditions, both initial and chronic
