You already know stress changes everything. But can you actually measure it?
Every day you work with people who sleep badly, recover slowly, get injured at the same time of year, and do not respond to the program the way they should. You know the nervous system is behind it. But you have no number to show.
I rely on my experience
It works. Until the client asks why they are not improving, or a colleague hands them a report backed by data. A gut feeling cannot be defended. Numbers can.
HRV tools already exist
They do. They are built for researchers, cost thousands of euros, produce reports nobody understands and take weeks to learn. They were never designed for your practice.
I show clients their progress
How? In words? Your client wants to see their own chart improving over time. They want a PDF to show their doctor. They want to understand why they feel different today than three weeks ago.
4 numbers. Everything you need.
Stress Index processes 24 HRV parameters and turns them into 4 indices on a 0-100 scale. You read them in a second. Your client understands them without a lecture.
- Stress Index
You know exactly how much the sympathetic system is dominating. Step in before the client hits the wall, not after.
- Recovery Index
Stop guessing whether they are ready for a heavier load. The number tells you when to push and when to hold back.
- Balance Index
The signature of the autonomic nervous system. At a glance you see whether the sympathetic-parasympathetic balance is where it should be.
- Energy Index
Real reserves, not perceived ones. Essential if you work on burnout, athletic performance or energy management.
Three steps. Then you have the report.
Connect the strap
Any Bluetooth heart rate strap. The Polar H10 is the benchmark for ECG quality, but many other sensors work too. One minute and you are ready.
Measure in 10 minutes
Your client sits down, you start the measurement. Stress Index reads the signal in real time and filters artifacts automatically. Zero setup.
