Last summer I dealt with OTS and it was similar to how you describe it, where the effort felt hard but HR did not increase in similar fashion and resting HR was maybe 2-3 bpm higher than when properly rested. The path into and path out of OTS are likely individual, but for me it was a matter of patience and accepting I dug myself into a bit of a hole (but I can try to lay the blame on raising a second dog for skijoring). Not getting outside was not a realistic/acceptable option, so I did continue to train, but with reduced volume, only easier effort (both in terms of RPE and HR), and no long runs – the total opposite of what would normally describe the summer season. Just as with coming back from an injury, every now and then I would push for a short section just to test how it felt, but never as a sustained effort. In short, it was a patience game.
I am currently returning to my training for (ultra trail) running, after having to take a break from almost all physical activity whatsoever in the last 2,5 months due to OTS or some similiar disease (probably stress burnout, doctors couldn’t find anything severely wrong with my body).
As expected, running, when the “lifestyle symptoms” had gone away and I restarted exercising, at the first few times felt unusually hard, but what is really triggering me and makes me think, is that I can’t seem to get up my heart rate without it feeling awfully exhausting – even when just running in Z1 or Z2, based on a 5 zone model with very exact measurements from the past.
I think this is mainly because of 2 reasons: First, my body is no longer used to running and strenous physical activity in general, since I had to almost completely stop doing any intense work, and I obviously lost some fitness, and second, that a lot of all this is only mental and psychosomatic in my head, because my brain is afraid or simply no longer used to even the only very low dose of intensity at these easy running zones.
This is really fascinating to me and leaves me wonder what’s wrong, since it is actually always the other way round: Most people find it extremely difficult to run with low heart rate and not having slow down excessively, while it is quite the opposite for me: My heart rate stays relatively low, even when going fast and/or uphill, but the RPE is unusually high.
Maybe my brain just got very lazy and comfortable and I now have to regain my love for being in the pain cave while my body is actually very fit and healthy 😀 My resting heart rate btw. also did not change that much, only rising from ~32 to ~36 during the forced break.
Does anyone have heard or had to deal of/with something similiar? I am really looking forward to hearing your opinion on this!!
