2.3. Monitoring biomarker changes over the course of sessions

To analyze the evolution of a biomarker over time, start by accessing the "Biomarker" tab and open "Session", then "Dynamics". You'll see the complete evolution of the biomarker over time.

In playback mode, you can move the cursor point by point to observe different parts of the evolution. At the bottom of the screen, marks indicate the separations between each part of the session. You can adjust the zoom for a more precise analysis, and navigate between the different parts of the session, whether second, third, etc.

You can add events by clicking where you wish. For example, if you perform a noteworthy action, you can mark this event. Once added, the event is visible as a mark at the bottom of the screen, and by clicking on it, you can access it again. You can also move the event by editing it, then confirming the new position.

Events are used to note important aspects of your practice and also appear in the summary of the various parts. The evolution graph is divided into several segments: very short-term (blue background for instantaneous evolution), medium-term, long-term and very long-term. The very long term provides an average over a longer period, requiring around 90 beats to calculate.

Analysis of the relationship between the very short term and the medium term is crucial. Sometimes, the very short-term curve is above or below the medium-term curve. When the curve is below, it is marked in red, and when it is above, it is marked in green. These indications provide important information for assessing instantaneous trends during testing.

Finally, a synthesis of the information is available in the form of a "flower" indicating energy and agitation levels. This summary can also be analyzed part by part to observe the evolution over the different sections.
