Info

This tool calculates values based on the standard maximal, symptom-limited Bruce treadmill test. The values calculated are estimated VO2 max, metabolic equivalents (METs) and functional aerobic impairment (FAI). The VO2 max is calculated based on duration and gender, while the FAI takes into account the age and and activity level. For this purpose, 'Active' was defined as exercising to the point of raising body temperature once a week when the reference group was originally tested.
