Tymewear posted an article discussing The Mobilization Index, a metric comparing HRR and BRR and having an indicator of stress during a workout.
Of course such a visualization is preferably displayed during a training on the garmin, at least being able to visualize the MI in Intervals after the training might give some ideas what happened and seeing when the athlete was cooked…
Is this possible in Intervals - or is something missing (e.g. is there a field to enter max BR??)
Is there anybody who can help me with this?
Seems you found your answer in another thread.
Here is another support method mentioned for tymewear
Thanks Tom - but I am looking for a graph like displayed in the article I linked in my initial posting.
Not HSI - but HRR against BRR…
This can be done in Intervals.icu. First you need to add a custom activity field “Max BR” to the sport in /settings. The value will be copied on to activities for the sport when they are analysed (like FTP etc.).
Then you can use max BR, the respiration and heartrate streams, and the athletes max HR to create a custom activity chart using Javascript and Plotly.
Or you can use max BR and the respiration stream to create a custom activity stream “BRR”. This can be plotted on the activity timeline with the existing HRR% stream on a custom chart. This is probably easier than Plotly.
But I think we will probably add “Max BR” (and BRR%) as built in things soon, so wait a little bit.
Edit: You also need “Resting BR”.
On a related note, how to you go about measuring “resting BR”? I didn’t find any info on that on the Tymewear site.
@david you are absolutely right - the Resting BR is not provided in the app. Perhaps it might be possible to determine it just with the iPhone app and enter the value somewhere in the workout profile?
I will just wait for your possible implementation, because I am not that good with javascript an Plotly…
It’s helpful to know how to calculate BRR% via custom fields
Also interested in plotting this. I guess the way to get a resting BRR% is simple to rest, record it and enter the lowest smoothed value as a static datapoint.
I think your links have been hacked or something?
My Garmin watch (FR255) gives resting BR as part of the daily stats. Not sure how accurate it is but a good rule of thumb is 15bpm.
Not the original ones but the links in the post Quoted by @JakaSpeech are spam.
@JakaSpeech should check his device for spamware!
I’ve seen this a couple of times before. When people quote a post with links, the links get hacked by something on their computer/mobile.
I removed the hacked url’s.
I’ve built this. Will make it public soon.
Edit: public now: Mobilization Index
Requires custom activity fields:
BRMax
BRMin
restingHR
I’ve made the MI plot like W’ so when HRR% meets BRR% it’s fully depleted.
How can I “find” the chart - now Mobilization chart under the Custom Charts, but perhaps om doing it ..the wrong way 
Are you looking under ‘activity charts’ and not ‘charts’?
I’ve add the chart in a new tab in Activity details. I got an error message, but under Settings the two values are populated. How to fix this?
Did you reanalyse your old workouts to use the new values?
The values HR and maxHR were already prevously set, but I just did a Re-analyze just to be sure, no change.
There are 3 ‘custom’ fields you need to enable and set values for:
BRMax
BRMin
RestingHR
These fields are also public so I recommend adding them to your settings page under the activity type.
Does this also work with the respirationrate values from a Garmin HR-strap?
