VO2Max: Bruce Protocol
Quickly measure and calculate your VO2Max and cardiovascular capacity
VO2Max is a measurement of your body’s ability to process a volume of oxygen and is indexed to your body mass. Achieving and maintaining a healthy cardiovascular system is one of the most important aspects of fitness. Because it measures your body’s capacity to process oxygen, it serves as a good indicator of how much you can safely exert yourself during exercise.
Bruce Protocol
Purpose
Estimate the body’s ability to deliver and extract oxygen to determine cardiovascular fitness level.
Equipment
Treadmill
Procedure
Bruce test is considered a maximal exercise test where the athlete or client runs to complete fatigue as the treadmill speed and incline are increased every three minutes. Record total running time.
Stages
- 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
