I have a question about LT (running).
Is it possible my LTHR (not LTv) increased after a prolonged break from training (end of season break, then a couple of days of flu-like symptoms)?
During last year’s season I’ve estimated my LTHR at around 188-190 bpm. This was done from various TTs and one lab test.
Last week I went and did another LT test, and this time the result was 198 bpm (the speeds were a lot slower but that’s a given since I’m at the beginning of the season).
The protocol they used was warm-up, 4 minutes all out at 5% grade, take blood and HR, rest for 1.5 minutes, then 4 minute repeats at a constant speed, increasing every repeat, until they saw a the lactate increasing again.
Any idea why it went up?

It is possible this increase in HR does not indicate an “improvement” in ability. Cardiac output depends upon HR and stroke volume. Stroke volume depends upon filling pressure and how well the heart relaxes, which requires energy and improves with training. When you start seeing an increase in lactate is due to peripheral supply/demand issues.
If your peripheral muscles had not lost as much capillary bed as your heart lost the ability to relax this could explain this result. If you were not relaxing as well from the layoff the body would be trying to compensate by increasing the HR to keep increasing CO until you saw the lactate increase.
bump cuz i see the committee is posting
