actually it was a bunch of tests today done on a tacx trainer earing a face mask hooked to a "gas analyzer". produced all kinds of data from carb burn, fat burn, ozygen usage, power output, cadence, HR, vo2max, etc, etc. So what did I learn:
1. my bodyfat is unbelievably 21%. I say unbelievably because I am definately someone who would described as overweight. after discussing my training patterns, and getting a rudimentary education on fat burn vs glycogen burn etc, it seems pretty obvious I don't spend enough time in fat burn zone
2. my vo2max of 55, was pretty low. given my body profile etc. I am only at 70% of my theoretical max vo2. the good news is that with better structured training I can increase this number
3. my v02max HR was 179. I beleive this is the same as my LT HR. I'm sort of surprised it is this high, as 179 is the highest HR I have every recorded historically on my HRM.
the tests today were tough as they are done with no breakfast and no warmup. for a 16 minute test I ended feeling pretty miserable. one thing I find interesting is that in my race last Saturday my average HR was 165. according to my tests today, that put me in an anerobic zone for the whole race. however during the race I never felt any leg burn, nor was I gasping for breath. I think a key difference is that in the race I was spinning with low resistance. the tests today are basically the opposite. now that I have some data, I can get on a better fitness program!
