I recently started using The Cyclist's Training Bible (written by Joe Friel) to (hopefully) get my cycling into the next gear.
The one statement that he makes that had me wondering is using your Lactate Thershold Heartrate (LT) as a measure of your Perceived Rate of Exc. (PRE). To get to your LT is quite easy, do a time trail (5, 10, 40km or 8-10miles). By taking your avg. heartrate during this and then multiplying it by a value given, you get a heartrate value which is the Super Threshold (Zone 5a). After this you are given a table with the heartrates for all levels. The test is done during every rest phase.
I have thought about this and would like to know if you agree with the following. My Max Hr is 195 (tested during a race). A friend of mine, has a max hr of 202 (also tested) but when doing rides, my HR stays on 170 where his stays on 180. If we look at it using the max HR method, we find that our % of max HR is about the same. His PRE is however much higher than mine. After having done the TT, we found that his LT level is lower than mine, thus solving abovementioned scenario.
Is this a logical (and good) way to work or should I resort to the old 220 - age (or the other 300 ways) way of calculating and using my max hr? Any thoughts?
P.S. Sorry aboutn the acronyms, a lot of typing if I don't
