1. A subject is limited to a treadmill speed of 5 mph and must achieve a MET level of 10, determine the treadmill elevation for the subject:
- elevation should be 7.5 %
2. A subject is limited to treadmill speed of 5.2 mph and must achieve a MET level of 11, determine the treadmill elevation for the subject:
- elevation should be 8.5 %
MET = vo2/3.5
vo2 = HC + VC + REST
