Session 3 Objectives
Objectives:
To define and discuss how Maximal Oxygen Uptake influences
physical performance.
To learn why high Vo2 Max level is an excellent indicator of
good health.
To learn how to read and utilize the norm charts for Vo2 max scoring.
To learn how to read and utilize the Bruce Protocol Formula for
Estimating VO2 Max.
SOLs: 11/12.1, 11/12.2, 11/12.3, 11/12.4, 11/12.5
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
Vo2 max
Stage 1 = 1.7 mph at 10% Grade
Stage 2 = 2.5 mph at 12% Grade
Stage 3 = 3.4 mph at 14% Grade
Stage 4 = 4.2 mph at 16% Grade
Stage 5 = 5.0 mph at 18% Grade
Stage 6 = 5.5 mph at 20% Grade
Stage 7 = 6.0 mph at 22% Grade
Stage 8 = 6.5 mph at 24% Grade
Stage 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).
