What's your max HR?

[OakLeaf]

I read something a while back about people whose resting HR was below 40, needing to take caffeine to keep their resting HR at a level that will supply enough oxygen to the heart and brain tissues. That's not me... I don't know my true resting value, but when I just lay around for a while it's in the mid to low 50s... but I think I'd worry if mine got TOO low.

Interesting...I've never heard of that being done before. Usually if somebody's heart rate is too low to get enough O2 to their brain etc. they get a pacemaker (assuming, of course, that the low HR isn't due to something reversible like a bad reaction to a medication).

Heck no - my husband's resting rate is waaaay low - sometimes his polar monitor shuts off because it thinks its not getting a signal, so it may even get into the 20's sometimes (polar shuts off under 30......) He can be sitting and talking to someone and be in the 40's - it kind of freaks them out somtimes when he gives blood, but its totally natural for him.

Miguel Indurain (famous cyclist from the 90's) had a resting rate of 25!

I was just thinking - I'm not a runner so I don't think about running max much, but my cycling max is 211- so concievably (I've never run until I wanted to puke....) since your running rates are possibly 10 beats higher than your cycling rates I could get a legitimate reading of 220....
