Note
Had a VO2 max test done this morning, as well as RMR and BIA. I'd never had any of these done before and found it fascinating. I still need some time to study the many charts I left with, but basically the tests confirmed some of what I already knew or suspected (the reassurance was nice) and gave me some excellent frames of reference for future training.
Perhaps the most useful piece of information was to be able to put some actual numbers on what my fat-burning zones (1 and 2) are, as well as what my AT/LT is (lower than I thought). I realized that I spent most of my training time in Zone 3, which isn't particularly effective at either teaching my body to use fuel as fat OR at getting rid of lactic acid in the higher zones. It also put into perspective why I tended to bonk in my ultras last year as I'd typically run the first hour or two in zones 4/5, run out of carbohydrate stores, and suffer for the remaining 4 hours!
Great info to have, and I look forward to putting it to use!
