HRV (Heart Rate Variability) tracking is based on analyzing the intervals between heartbeats at rest. It gives an insight into the nervous system and helps understand how the athlete is absorbing training.
In the HRV tab, you can:
select the measurement protocol suited to your team;
create or edit custom protocols (posture, duration, etc.);
1. Access the "HRV" tab
Step | Action |
1 | Click your avatar ➜ Settings. |
2 | In the Nolio section, select HRV. |
2. Understanding measurement protocols
A protocol defines:
Posture (lying down, standing or custom).
Duration of each step (in seconds).
Exclusion windows: the first X and last X seconds ignored to stabilize the signal.
LF/HF threshold: the pivot value to interpret the sympathetic / parasympathetic balance.
Tip: 5 minutes lying down with a few seconds excluded at the start and end is a scientifically validated standard.
3. Default protocols
Name | Steps | Notes |
Lying / Standing | 5′ lying down ➜ 5′ standing | Includes the transition; informs on variability. |
Nolio protocol | 5′ lying down | Simple, reliable; ideal for the morning reading. |
Nolio protocol (finger) | 2′ lying down | Simple, fast. |
Click ✔ Use this protocol to activate the one you want (only one active at a time).
4. Create a custom protocol
Click Add a protocol (blue + button).
In the window:
Name: a short title (e.g. Finger morning).
Description: purpose or equipment used.
Step:
Field | Example |
Posture | Lying down; Standing; Custom |
Duration | 300 sec |
Exclude the first X seconds | 30 sec |
Exclude the last X seconds | 30 sec |
LF/HF threshold | 0.15 |
(Optional) Click + Add a step to chain a standing test.
Options:
Chain steps without a pause on the mobile app: continuous mode.
Clean the data before calculation: applies an algorithm to filter artifacts (outliers).
5. Edit or delete
Action | Procedure |
Edit | Click ✏️ edit; adjust steps or thresholds; Save. |
Delete | Click 🗑️ delete in the protocol card, then confirm. |
HRV readings already recorded stay in the history even if you delete the original protocol.
