  2. Surface roughness - Wikipedia

    en.wikipedia.org/wiki/Surface_roughness

    The basic GD&T symbol for surface roughness. Surface roughness or simply roughness is the quality of a surface of not being smooth and it is hence linked to human perception of the surface texture.

  3. Heart rate variability - Wikipedia

    en.wikipedia.org/wiki/Heart_rate_variability

    Exercise training may decrease cardiovascular mortality and sudden cardiac death. Regular exercise training is also thought to modify cardiac autonomic control. Individuals who exercise regularly have a 'training bradycardia' (i.e., low resting heart rate) and generally have higher HRV than sedentary individuals. [85]

  4. Heart rate - Wikipedia

    en.wikipedia.org/wiki/Heart_rate

    The Karvonen method factors in resting heart rate (HR rest) to calculate target heart rate (THR), using a range of 50–85% intensity: [54] THR = ((HR max − HR rest) × % intensity) + HR rest. Equivalently, THR = (HR reserve × % intensity) + HR rest. Example for someone with a HR max of 180 and a HR rest of 70 (and therefore a HR reserve of ...

  7. 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 ...

  9. Rate pressure product - Wikipedia

    en.wikipedia.org/wiki/Rate_pressure_product

    The calculation formula is: Rate Pressure Product (RPP) = Heart Rate (HR) * Systolic Blood Pressure (SBP) The units for the Heart Rate are beats per minute and for the Blood Pressure mmHg.
