MET reflects the oxygen consumption during rest and sitting. It is 3,5ml O2 /kg body weight/min. The metabolic equivalent is used to determine the energy expenditure during the maximum load. The metabolic equivalent in custo diagnostic is calculated as follows:
a) Treadmill exercise test:
v = max. Speed in miles per hour
m = slope in%
MET = 1 + (v * 26.8 * (0.1 + m * 0.018)): 3.5
b) Bicycle exercise test:
L = max. Load in Watts
G = weight in kg
MET = 1 + (12 * L): (3.5 * G)
