3. 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

4. Vo2 max Stage 1 = 1.7 mph at 10% GradeStage 2 = 2.5 mph at 12% GradeStage 3 = 3.4 mph at 14% GradeStage 4 = 4.2 mph at 16% GradeStage 5 = 5.0 mph at 18% GradeStage 6 = 5.5 mph at 20% GradeStage 7 = 6.0 mph at 22% GradeStage 8 = 6.5 mph at 24% GradeStage 9 = 7.0 mph at 26% Grade The Bruce Protocol Formula for Estimating VO2 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 T=9.5).
