Vo2 max

• Fitness can be measured by the volume of oxygen
  you can consume while exercising at your maximum
  capacity.

• Vo2 max also can be estimated. There are a
  variety of protocols used to estimate VO2 max,
  one is called the Bruce Treadmill Test, but none
  are as accurate as direct testing.

• The Bruce Protocol is a maximal exercise test
  where the athlete works to complete exhaustion as
  the treadmill speed and incline is increased
  every three minutes

Max For Men VO2 max 14.8 - (1.379 x T)
(0.451 x T²) - (0.012 x T³) For Women VO2 max
4.38 x T - 3.9 T Total time on the treadmill
measured as a fraction of a minute (ie A test
time of 9 minutes 30 seconds would be written as
T9.5).
