Need some advice in TSS

zadow

@sorinus AFAIK, Suunto app does not offer RPE tracking. I am logging it via Training Peaks app.

@jjorgemoura Please see the description I posted a few posts earlier, when I do an interval workout that is the purpose. I don’t think the classification matters. The watch will record power and HR for the time you spent in those zones and apply TSS values.

@sorinus Please see what @zadow stated. No watch can track RPE.

After some training using the default TSS(hr) I conclude that if the HR tracking is not accurate then the TSS is not accurate as well.
Unfortunately the OHR on my Vertical is missbehaving badly, like recording a HR way higher than how I feel. It suddenly jumps 30 to 40 points higher and stays there for many minutes. I’m not sure is because of the cold weather, or in general, since I have the watch for a bit over 1 month.

So I wonder if using the TSSr is better in such case, especially since it looks like it accounts for non-even terrain during trail running (via NGP). This article explains it well https://www.trainingpeaks.com/learn/articles/running-training-stress-score-rtss-explained/. Even if the TSS value is not that accurate at least it will be a consistent value accros runs. Thoughts?

I simply have to comment on the RPE scales, of which there are many. The original was constructed by Gunnar Borg within the psychology/medicine field in the 1960s. He used a theoretical male with a resting HR of 60 and a max of 200. The scale then became 6-20 where the ‘feeling’ of light exercise at say 130 bpm would correspond to a 13 on the scale. He later simplified the scale down to a 0-10 rating.

I myself use the totality after a workout; how winded was I, how much did the muscles burn and how much fatigue do I feel standing here in the shower… Mostly my exertions fall in the 3-4 rating for easy runs up to an hour in length. But that is just me and my use of a 1-10 RPE scale.

@sorinus The Uphill Athlete (I do not agree with their Aerobic Deficiency ideas!) suggests to add 10 TSS points for every 300m (1000 feet) elevation gain AND loss during a trail run to hrTSS as hrTSS and rTSS cannot adequately assess the stress. For example a slow very steep uphill power hiking could have elevated HR but rTSS will be widly inaccurate. A technical downhill requiring a lot of muscular stress from eccentric contractions will be slow and again neither hrTSS nor rTSS will be adequate.

I found TSS (Met) to nearly exactly match hrTSS+10TSS for every D+/- of 300m. So I use TSS Met in Suunto app and add the TSS pts to my trail runs in TrainingPeaks.

@Brad_Olwin I missed it, what’s TSS Met?

Brad_Olwin

@stromdiddily
MET is metabolic equivalents and supposedly the least accurate but works for me.

@Brad_Olwin Thanks for the information, but at the moment I can’t use it because I can’t use hrTSS - the OHR varies too much.
So until I start using a proper chest strap I have to use something else that even if it’s not accurate at least is consistent and rTSS is the one that I find it makes sense - at least judging from its description using NGP makes it suitable for trail runs as well.
Tomorrow I will do a test run on a trail run and see how much different is vs hrTSS. Then will do a flat run and compare as well. But in the end I feel like I’m wasting time and should just get a chest strap.

I would also like to thank the commenters in this thread because your words resolved a quandary I encountered today: My 70 minutes run well below AeT was given a TSS of 81 and a very visible peak in the SA ‘Progress’ graph. Looking at the details of the activity the TSS was defined as TSS , as opposed to previous runs which had been TSS (hr).

Searching the web for the method by which Suunto classifies the activity, an article (at Suunto) said that is was automatic but based on how we had defined our HR/Pace and Power Zones. And it so happens that I changed unrealistic paces yesterday (they were much too fast) to measured and estimated values more in line with the AeT and AnT HR results. So my editing seems to have given the SA a sort of ‘go ahead’ to use TSS as a default for running.

Another posting, think it was in this forum, spoke about how you got a choice when editing the TSS at TrainingPeaks of which method you would like as the default in the future. Trying the same strategy in the SA yielded the exact same result. I was asked if I would like the TSS (hr) only for this activity, or to set it as a default.

The TSS (hr) today of 57 I would deem much closer to reality than the TSS (r ) of 81 - if indeed a TSS of 100 should be considered as 1 hour at AnT.

PS: Sorry about the Registered marks above. I’m writing in a sideloaded Chrome browser on a ‘Smart TV’ and can’t scroll backwards to change the text, which should read as TSS (r )…

@sorinus Agreed. I do not exercise without a strap. Plus ZoneSense is a game changer.
