The metabolic cost of transport includes the basal metabolic cost of maintaining bodily function, and so goes to infinity as speed goes to zero. [1] A human achieves the lowest cost of transport when walking at about 6 kilometres per hour (3.7 mph), at which speed a person of 70 kilograms (150 lb) has a metabolic rate of about 450 watts. [1 ...
The relationship between walking and cost of transport is parabola-like with the preferred walking speed at the minimum, meaning walking at a slower or faster speed can incur a similar increase in energetic cost for a 1-kilometer walk. [1] Within each walking speed, the step length and cadence are also optimized for metabolic cost. While ...
It is also common to measure the cost of transport (COT), or the energetic cost to travel a given distance, in order to make comparisons of economy between individuals. Because this value is thought to remain constant across speed, the measurement of the COT at any single fixed submaximal speed is thought to provide an adequate representation ...

In contrast, other researchers have suggested that gross cost of transport may not represent the metabolic cost of walking. People must continue to expend their basal metabolic rate regardless of whether they are walking, suggesting that the metabolic cost of walking should not include basal metabolic rate. Some researchers have therefore used ...
According to Hugh Herr, the performance of an orthosis should be based upon measurements of "metabolic cost of transport, walking speed, smoothness and repeatability of motions, muscle fatigue, and stability" as well as "the reduction of forces borne by the musculoskeletal system". [1]
