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 ...
The dynamic energy budget (DEB) theory is a formal metabolic theory which provides a single quantitative framework to dynamically describe the aspects of metabolism (energy and mass budgets) of all living organisms at the individual level, based on assumptions about energy uptake, storage, and utilization of various substances.
Cori cycle. The Cori cycle (also known as the lactic acid cycle), named after its discoverers, Carl Ferdinand Cori and Gerty Cori, [1] is a metabolic pathway in which lactate, produced by anaerobic glycolysis in muscles, is transported to the liver and converted to glucose, which then returns to the muscles and is cyclically metabolized back to lactate.
Commonly, individuals place some value on their time. Economic theory therefore predicts that value-of-time is a key factor influencing preferred walking speed.. Levine and Norenzayan (1999) measured preferred walking speeds of urban pedestrians in 31 countries and found that walking speed is positively correlated with the country's per capita GDP and purchasing power parity, as well as with a ...
Humans expend energy through their basal metabolic rate, the thermic effect of food, non-exercise activity thermogenesis (NEAT), and exercise. [8] While many treatments for obesity are presented to the public, exercise in the form of walking is an easy, relatively safe activity.
In biology, the biological cost or metabolic price is a measure of the increased energy metabolism that is required to achieve a function. Drug resistance in microbiology, for instance, has a very high metabolic price, [ 1 ] especially for antibiotic resistance .
