Maximum Heart Rate

Hello,

Are there any dangers with exerting yourself too hard when doing cardio? Yesterday I was doing some uphill treadmilling and I got my heart rate up to about 187bpm. I was in no discomfort but I thought I should slow things down just in case, as that did seem a little high.

I am 23 so theoretically my 'maximum heart rate' is 220-23=197 right? But what the hell is a 'maximum heart rate'? If I hit 197 would I suddenly combust or something?[V]

For the record, my resting HR is about 55bpm, but before my cardio yesterday I had indulged in some pre workout xenadrine, so my resting HR was up to about 80bpm....

Any advice? Cheers!

    Your maximal heart rate is the highest number of times your heart can beat in a minute of exercising at volitional exhaustion. Maximum heart rate is a genetically determined "random" variable so your heart rate is individual to you. You should therefore take this value with a pinch of salt; The accepted error in the age-predicted formula is ± 10-12 bpm, so your heart rate could be as high as 209bpm.
    But this is only an estimate and the only real way of getting an persons maximal heart rate is through clinical testing. If your comfortable working at that heart rate then you'll be fine (unless you have a heart condition), use a scale from 1-10, 1 being very very light work and 10 being very very heavy. Then see where you rate with your associated heart rate (10 should be maximal). Do this with a exercise perfessional and not on your own as you'll be working maximally.
    Good Luck
    p.s. it may have been the xenadrine!

    do a search for a hr calculator which takes rhr/sex into account. the 220 model is based on average fitness males.

    www.sportsdigest.co.za/hrcalc.shtml works well for me.
