I agree that Karvonen is not the magic formula and neither did they want it to be a industry standard when they developed it for research reasons only. Its just that everyone latched on to the idea that HR and intensity where linked in stone. The HRM is a great tool for those people that are going to measure their fitness increases over time. But as far as during the work out -though it is true that linearly the intesity will match the BPM up till where just before you go breathless- its at that point when you hit deflection that the HRM is no longer sugnificant to you and that you will only be able to hold on to what HPE that you can sustain for the given fitness level and activity that you have undertaken. It is not necessary to train your self past going breathless- as a matter of fact you have a great chance of hurting yourself with sustained anaerobic activity due to over exertion and getting to and holding near max HR's. I find it very cool to see OLN put up HR's of the racers on the screen where they will be cruising along in the peleton at speed and their HR is only like 135 BPM
then in the last part where the "quacking" starts they reach up to an average of 186 BPM for the last minute or so where they litterally blow up. So as we become more fit the idea is to see those efforts become easier at a certain range of numbers or that we can hold those higher numbers for longer working as close to our max HR whilestill using air for the fuel mixture.
