    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 ...

    [citation needed] The heart rate formula most often used for the Bruce is the Karvonen formula (below). A more accurate formula, offered in a study published in the journal, Medicine & Science in Sports & Exercise, is 206.9 - (0.67 x age) which can also be used to more accurately determine VO2 Max, but may produce significantly different results.

    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 ...
