Information

This calculator allows you to estimate the METs and VO2 given the treadmill speed and the grade. It is useful for situations when you want to use the non-standard treadmill protocol to find out exactly how much the patient can do.

Speed = Treadmill Speed * 26.8
Horizontal Component (HC) = Speed * 0.1
Vertical Component (VC) = Speed * 1.8 * Grade

VO2 = HC + VC + Rest = HC + VC + 3.5 mL/kg/min

Mets =
