Crazy High Polar VO2 Max

[Eden]

While I'm am guessing that your polar watch is rather likely to be overestimating at 77 (it a can only guestimate - an actual V02 requires that the air you are breathing be sampled and the formulas those watches use to guess are notoriously inconsistant), it is more than possible that you do have a high V02. While V02 is a little trainable, most of it (experts say 80%) is genetically determined. Also, simply having a high V02 doesn't automatically mean you will be a great athlete - you have to have all the other factors too - high LT, strong muscles, big lungs etc. I've had mine professionally measured at a little under 72, which is the highest my coach has personally tested in a woman, but I'm certainly not a pack superstar...

Back to your watch though - have you done a max hr test and set it, or have you based your max on the 220-age formula? I'm thinking that right there could be the explanation for the extremely high V0 rating - if it thinks your max hr should be relatively low, but you really have a high max, then it believes during your VO2 "test" that you are working for a long time at a really high capacity..... I'm betting that could easily skew the results of the test.
