2. 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 ...

   [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.

5. 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. Rate pressure product is a measure of the stress put on the cardiac muscle based on the number of times it needs to beat per minute (HR) and the arterial ...

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 ...

8. Heart rate variability - Wikipedia

   en.wikipedia.org/wiki/Heart_rate_variability

   Heart rate variability (HRV) is the physiological phenomenon of variation in the time interval between heartbeats. It is measured by the variation in the beat-to-beat interval. Other terms used include "cycle length variability", "R–R variability" (where R is a point corresponding to the peak of the QRS complex of the ECG wave; and R–R is ...

9. Cardiac physiology - Wikipedia

   en.wikipedia.org/wiki/Cardiac_physiology

   The resting heart rate of a newborn can be 120 beats per minute (bpm) and this gradually decreases until maturity and then gradually increases again with age. The adult resting heart rate ranges from 60 to 100 bpm. Exercise and fitness levels, age and basal metabolic rate can all affect the heart rate. An athlete's heart rate can be lower than ...
