Exercise Capacity (METs & VO2)

share this tool –

Clinical Use

Estimate exercise capacity based on performance from exercise treadmill test


\[VO_2 = Speed \times [0.1 + (Grade \times 1.8)] + 3.5\]

\[METs = \frac{VO_2}{3.5}\]


Speed in m/min = Speed in mph x 26.8

Grade expressed as a fraction

Reference Values

Classification of Estimated Functional Capacity According to Age and Gender
Age (yr)Estimated Functional Capacity (METs)
METs = metabolic equivalents


1 MET = 3.5 ml/kg per min of oxygen consumption
