Notes:
1.
The horizontal equivalent speeds (miles and kilometers per hour) are approximations based on
average energy expenditure.
2.
The Calories/Hour and METS figures are based on an estimate of 20% metabolic efficiency.
Actual caloric use will vary for each individual.
3.
Kilopond-meters/second (KPM/S) = (speed in meters/second) X (weight in kilos).
4.
Watts = (speed in meters/second) X (weight in kilos) X (9.8 meters/second
2
).
