I was a national level 5k runner in Canada
I often have doctors tell me that my resting heart rate was too low for the machine to read. The lowest I’ve clocked is 34 bpm.
I assume there’s a safe limit to how low a heart rate can go, which makes me wonder what the limit to cardiovascular performance in running is.
- ausbah 8y agoI've heard of some professional cyclists years ago who turned their bodies into such efficient biking machines from training + drugs that when they when to sleep, there was a change of them dying in their sleep because their heart rate was so slow. They'd have to get up in the middle of the night and bike just to stay alive. Only anecdotal, but worth considering. https://www.youtube.com/watch?v=hT8GZlBBv5k https://www.youtube.com/watch?v=hT8GZlBBv5k
- trymas 8y agoI understand it's anecdata, but I still do not completely get how you can die from slow heart rate? Why heart shouldn't get a signal to beat more frequently if body starts to lack oxygen during sleep? Is it just because the blood is so thick and moving so slow it will clog and may produce a sudden heart attack? Thus you need to "manually" keep up the heart rate?
