  3. Metabolic equivalent of task - Wikipedia

    en.wikipedia.org/wiki/Metabolic_equivalent_of_task

    The metabolic equivalent of task (MET) is the objective measure of the ratio of the rate at which a person expends energy, relative to the mass of that person, while performing some specific physical activity compared to a reference, currently set by convention at an absolute 3.5 mL of oxygen per kg per minute, which is the energy expended when sitting quietly by a reference individual, chosen ...

    en.wikipedia.org/wiki/Running_energetics

    As a result, it is common to express energy expenditure as the rate of oxygen consumption in relation to body mass (ex. ml/kg/min). [ 8 ] Though some recent data may suggest otherwise, [ 9 ] it is traditionally well accepted that a strong linear relationship exists between the rate of oxygen consumption and running speed (see figure 1), with ...

  5. VO2 max - Wikipedia

    en.wikipedia.org/wiki/VO2_max

    V̇O 2 max (also maximal oxygen consumption, maximal oxygen uptake or maximal aerobic capacity) is the maximum rate of oxygen consumption attainable during physical exertion. [1] [2] The name is derived from three abbreviations: "V̇" for volume (the dot over the V indicates "per unit of time" in Newton's notation), "O 2" for oxygen, and "max" for maximum and usually normalized per kilogram of ...

  6. Running economy - Wikipedia

    en.wikipedia.org/wiki/Running_economy

    Running economy (RE) a complex, multifactorial concept that represents the sum of metabolic, cardiorespiratory, biomechanical and neuromuscular efficiency during running. [1]: 33 [2] [3] Oxygen consumption (VO 2) is the most commonly used method for measuring running economy, as the exchange of gases in the body, specifically oxygen and carbon dioxide, closely reflects energy metabolism.

  7. Energy density - Wikipedia

    en.wikipedia.org/wiki/Energy_density

    In light-water reactors, 1 kg of natural uranium – following a corresponding enrichment and used for power generation– is equivalent to the energy content of nearly 10,000 kg of mineral oil or 14,000 kg of coal. [16] Comparatively, coal, gas, and petroleum are the current primary energy sources in the U.S. [17] but have a much lower energy ...

    Costing is based on an average cost for oxygen and different fuels in May 2012. [ obsolete source ] The opex with Gasoline was 25% that of propane and 10% that of acetylene. Numbers will vary depending on source of oxygen or fuel and on the type of cutting and the cutting environment or situation.
