    Caffeine and heart rate

    I know caffeine and other stimulants affect your heart rate, but how much can a few cups of coffee raise you're max? I usually top out around 195 bpm, but I've gotten up to 205 when I was really, really wired hitting a big climb.

    Does that sound realistic? I haven't really experienced radio interference with my HRM in that area before, but it could be a bad reading. Also, is something that raises your real-world max HR by 10 bpm even safe?

    Go out and do a real max HR test with and without caffiene and tell us the results. The hr you hit going really hard on a climb is not likely to be your true max. I don't think caffiene should change it.

    You can't change your max heart rate, it is a true biological physical limit. It will go down with age though. It seems like you are calling the highest number you've ever seen as your max - obviously it wasn't (assuming the 205 was a valid reading -and that probablly wasn't your max either).

    I suppose it's possible that a big dose of caffeine could help you get closer to your max.

    Caffeine doesn't change your max heart rate. Caffeine (and other stimulants) merely raise your current heart rate to a rate closer to your max...

    My Max HR is somewhere above 216 w/o any stimulant help. Coach had to back off a test and call it good cause it kept going up, lol!

    Where does the conventional "220 minus age" number for max HR come from?

    I had my tested at a lab. And my guess was spot on. 184.
    Even with 2 gallons of coffee that's about where I max out sometimes. Cocaine is a different story.
