resting day.... VO2max-Research

today no training, but some stretching. time for some paper-work & "VO2max"-research in the office:

VO2max is one of the most important success factors for endurance sports such as triathlon. A very good website about VO2max I found at: http://www.brianmac.demon.co.uk/vo2max.htm
There it is stated: "Fitness can be measured by the volume of oxygen you can consume while exercising at your maximum capacity. VO2 max is the maximum amount of oxygen in milliliters, one can use in one minute per kilogram of body weight." I did a test with my polar equipment showing an ownindex of 58, which should be very good according to polar.
