Please help me get xSS into activities page/weekly totals

[Lukasz_Sleszynski]

Hello everyone! I am absolutely ashamed to post a simple question like that, but I have been trying to get a specific data show onto activity page for 15+ hours and couln’t figure it out.

Few months ago Intervals.icu introduced xSS/SS that I managed to show on activity page (screen below) and it works absolutely amazing.

However I would like to have it just like on screenshot below.

1. In daily wellness plots/daily summary, or however it’s called - it’s xSS on this screenshot
2. In weekly totals, just like a load
   
   

Could someone help me with this (probably) insanely simple question?

Think I misssd out. What is the xss/ss? Steady state? Sweet spot?

XSS is XERT Strain Score - or at least I think David has incorporated them somehow. there is a forum post on this https://forum.intervals.icu/t/three-dimensional-impulse-response-model/109644

Don’t know if there is another option, but you can do it with a fitness chart. Create one chart with your metrics and click the three dots

There you can tick to show it on the calendar and on which days in the options.

R2Tom’s approach will work. What you can also do is use a custom activity field to replace the Intervals.icu training load (basically TSS) with XSS. We haven’t added this as a default option because XSS is often quite a bit more than TSS (my most recent ride XSS=248 TSS=209) and the other load calculators for HR and pace output TSS.

Add a custom activity field “XSS Load” with a script like this:

{
  if (activity.strain_score) activity.icu_training_load = Math.floor(activity.strain_score + 0.5)
  activity.strain_score
}

First I thought it was working but actually not… If you use “As Is” then on the Weekly Totals, it will display the XSS value of the activity made on Sunday, not the sum of all XSS values of all activities in that week… I had to change the setting of the plot, to show as “Moving Total” and Last 7d.
Happy to receive comments if this is not proper set up, I’m a beginner to customizing Intervals

Guys, you are absolutely amazing. So much help within 24hours. Thanks to you I managed to do EXACTLY what I wanted and without your help/ideas for sure I wouldn’t manage to do so.

For people that would check this topic in the future.
This is how my weekly calendar looks like now:

I managed to put xSS onto calendar AND xSS weekly total into totals by creating xSS chart in fitness tab. Then I had to add 2 plots:

Then I edited layout of both them, 1 to show on every calendar day, but not in total summary.
This one is “as is” plot, per training session:

This one is “weekly total” plot:

Big, big thank you to everyone included.

I still struggle on my end. Note that I do only running (road and trails). Could you summarize the additional metrics you display on calendar (totals and activity details), compared to defaults, and what benefits / use you make from them?
Right now I monitor load mainly using Final Surge (total elapsed time of run activities for the week, and total distance/elevation), and in addition, the total RSS load in Stryd.
But I’d like to explore how Intervals is evaluating load. I also see some load indicators in Strava, but numbers look slightly different.

Hey! I am not sure if this question was directed to me, but I am more than happy to answer and try to help you.

1. I’d like to explore how Intervals is evaluating load - 100 LOAD is 1 HOUR at 1 HOUR MAX EFFORT effort (i.e. 1.0 IF), so for example 100 LOAD is also 2 HOURS at 50% of 1 HOUR MAX effort.
2. Could you summarize the additional metrics you display on calendar (totals and activity details), compared to defaults, and what benefits / use you make from them?
   I) activity details as screenshoted:
   143bpm - average heart rate during activity
   208W - average power
   Load 124 - load generated by activity

I believe these 3 above do not need any explanation

69% - intensity factor - summarized IF for activity. The intensity of a ride is a measure of how hard it was compared to your FTP. It is calculated by dividing the normalized watts or weighted average power for the ride by your FTP. If you are able to complete a ride of 1 hour or longer at more than 100% intensity then your FTP is too low. For activities without power intensity is derived from the training load and duration.

1637 kJ - total usage of energy
27 kJ - usage of energy done above FTP - shows how much time/effort I have done above FTP which is much more demanding than riding at or below FTP.

II) weekly totals

total time, total load, total kcal, total elevation - do not need explanation i believe

fitness - this is calculated by intervals and is basically a chronic load over last few weeks

fatigue - chronic fatigue (will increase and decrease much faster than fitness)

form - fitness minus fatigue

HR Load - Intervals.icu can estimate training load for activities without power data by using previous activities with power and heart rate data. Either the time in each HR zone or the average HR for each activity is used. This works well for cycling but does not generalize well to other sports. For running and other sports HRSS works better. This is [TRIMP] normalized to more closely match power based training load. You need to capture your resting HR for HRSS.

CIL - is a 42 day exponentially weighted moving average of the intensity for each activity. It is similar to fitness but removes the weighting for duration. It is a useful measure to look at when you are trying to reduce volume and maintain or increase intensity

kJ>FTP - explained above

xSS - is load but calculated like xert would do. Basically load calculated by intervals very much underestimates riding in Zone 2, and xSS helps a little bit with analyzing what happened. We could talk about xSS hor hours so I advice you to just watch some youtube videos about it.

I am not sure if this is what you expected so feel free to ask further questions.
