guess it using the provided formula (220 minus your age) or measure yourself with a pulse meter as you are exercising, gradually increasing in intensity until you reach your maximum tolerable exertion, them measure your heart rate at that point.
It says pretty clearly what they are in the calculator page. Different ranges of heart rates will essentially give you a guide to how your body will perform and how much physical stress you put on it.
Ok, so the idea is if you go past your max heart rate you won't be able to effectively perform athletically??
Not that you'd have a heart attack at that point lol...
Also though...doesn't passing your max heart rate just mean you'd fatigue AEROBICALLY in terms of lung capacity??
What does that say about the intense MUSCLE CRAMPING I get in my arms and legs which are in fact the worst part of the fatigue I experience??
That's why I was wondering how the earlier article played into the information that you and Mad Dash are giving me.
I DO experience involuntary muscle cramping and it is my MUSCLES more so than my heart which seem to unable to perform properly when I consume too much caffeine.
Why would this be if it is all about the heart??
Something to do with the heart not being able to get sufficient blood supply to the extremities or something like that??
Or maybe it has to do with lactic acid??
I went back and looked at the calculator and now I get it so maybe I'm in that lactate zone where I am producing too much lactic acid in my muscles when they are fatiguing.
It also says you should "only train in your red line zone if you are very fit and only for a very short period of time", but the problem is that when I am doing Jiu-Jitsu, Muay Thai, boxing and MMA training I have NO IDEA what my heart rate is and I"m not just able to stop sparring in the middle of it and take my heart rate to find out if I should continue or not lol....
I mean, what happens if I AM in that red line zone and I just keep going??
Am I going to have a heart attack or stroke or something?
Or am I more likely to just fatigue and slow down because I can't go any faster??
That's usually what happens when I get to the point where I am fatigued, I may "keep going" but I'll be going at a snail's pace which I guess is my body's way of protecting my heart from overwork??......
