I’m curious as to what influences how fast the HR drops after exercise, as well as what relevant information it may give.
I’ve noticed that after long, slow, aerobic runs, my HR drops pretty dramatically, like 40 or 50 beats within a minute after stoping. Even if I’ve been running for like 4 hours. So I could be running at 155bpm, stop and watch my HR drop to 100 or 110bpm in a minute. The same isn’t truth with interval training, after which my HR will stay a bit higher for longer. I’m no expert on the matter but I suppose it might perhaps be due to the high demand placed on the body, which may force the body to work harder, thus higher HR, to restore homeostasis? But I’m not sure.
I’ve read an article on Martin Fourcade saying he could lower is heart rate from 170-180bpm to 100bpm very quickly when shooting. According to the same source, he has one of the biggest HR drops across the elite biathlon world. I’ve also read Kilian Jornet would be at 70 or 80bpm like a minute after going all out on a Vo2max test.
So, what affects how fast the HR drops and how relevant is it?
