  2. Respiratory quotient - Wikipedia

    en.wikipedia.org/wiki/Respiratory_quotient

    A RQ near 0.7 indicates that fat is the predominant fuel source, a value of 1.0 is indicative of carbohydrate being the predominant fuel source, and a value between 0.7 and 1.0 suggests a mix of both fat and carbohydrate. [6] In general a mixed diet corresponds with an RER of approximately 0.8. [7]

  3. Heart rate - Wikipedia

    en.wikipedia.org/wiki/Heart_rate

    It is usually equal or close to the pulse rate measured at any peripheral point. [2] The American Heart Association states the normal resting adult human heart rate is 60–100 bpm. An ultra-trained athlete would have a resting heart rate of 37–38 bpm. [3] Tachycardia is a high heart rate, defined as above 100 bpm at rest. [4]

  4. Gram - Wikipedia

    en.wikipedia.org/wiki/Gram

    The gram (originally gramme; [1] SI unit symbol g) is a unit of mass in the International System of Units (SI) equal to one thousandth of a kilogram.. Originally defined in 1795 as "the absolute weight of a volume of pure water equal to the cube of the hundredth part of a metre [1 cm 3], and at the temperature of melting ice", [2] the defining temperature (≈0 °C) was later changed to 4 °C ...

  5. Cardiac output - Wikipedia

    en.wikipedia.org/wiki/Cardiac_output

    Major factors influencing cardiac output – heart rate and stroke volume, both of which are variable. [1]In cardiac physiology, cardiac output (CO), also known as heart output and often denoted by the symbols , ˙, or ˙, [2] is the volumetric flow rate of the heart's pumping output: that is, the volume of blood being pumped by a single ventricle of the heart, per unit time (usually measured ...

  6. 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 ...

  7. Biological half-life - Wikipedia

    en.wikipedia.org/wiki/Biological_half-life

    Time course of drug plasma concentrations over 96 hours following oral administrations every 24 hours (τ). Absorption half-life 1 h, elimination half-life 12 h. Biological half-life ( elimination half-life , pharmacological half-life ) is the time taken for concentration of a biological substance (such as a medication ) to decrease from its ...

  8. Dry matter - Wikipedia

    en.wikipedia.org/wiki/Dry_matter

    For example, a 138-gram apple contains 84% water (116 g water and 22 g dry matter per apple). [5] The potassium content is 0.72% on a dry matter basis, i.e. 0.72% of the dry matter is potassium. The apple, therefore, contains 158 mg potassium (0.72/100 X 22 g).

  9. Body surface area - Wikipedia

    en.wikipedia.org/wiki/Body_surface_area

    In physiology and medicine, the body surface area (BSA) is the measured or calculated surface area of a human body.For many clinical purposes, BSA is a better indicator of metabolic mass than body weight because it is less affected by abnormal adipose mass.
