walking equation

vo2 = (0.1 x speed(m/min)) + (1.8 x speed x grade) +3.5

running/jogging equation

vo2 = ( 0.2 x speed) + (0.9 x speed x grade) +3.5

stepping equation

vo2 = (0.2 x steps/min) + (1.33 x (step height x steps/min) +3.5

leg cycling equation

vo2 = 3.5 + 3.5 + (1.8 x work rate) / body mass

arm cycling equation

vo2 = 3.5 + (3 x work rate) / body mass
