Now I agree. The formula was confusing me. from the same medical source:

"VO2 max, or maximal oxygen uptake, is one factor that can determine an athlete's capacity to perform sustained exercise and is linked to aerobic endurance. VO2 max refers to the maximum amount of oxygen that an individual can utilize during intense or maximal exercise. It is measured as "milliliters of oxygen used in one minute per kilogram of body weight." V02 max should not be confused with the lactate threshold (LT) or anaerobic threshold (AT), which refers to the point during exhaustive, all-out exercise at which lactate builds up in the muscles during exercise. With proper training, athletes are often able to substantially increase their AT and exercise longer at a higher intensity."

I have been trying to get my doctor to send me for a vo2 max test so my insurance would pay for it. So for my excuses haven't been convincing I guess?
