2. Heart rate - Wikipedia

   en.wikipedia.org/wiki/Heart_rate

   The maximum heart rate (HR max) is the age-related highest number of beats per minute of the heart when reaching a point of exhaustion [28] [29] without severe problems through exercise stress. [30] In general it is loosely estimated as 220 minus one's age. [ 31 ]

3. 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 ...

4. Cardiac output - Wikipedia

   en.wikipedia.org/wiki/Cardiac_output

   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 per minute). Cardiac output (CO) is the product of the ...

   Keep in mind that depending on your age, your goal heart rate will differ. This table shows target heart rate ... Count your pulse for 15 seconds and multiply by 4 to find your beats per minute.

6. Bruce protocol - Wikipedia

   en.wikipedia.org/wiki/Bruce_protocol

   [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.

7. Cardiac cycle - Wikipedia

   en.wikipedia.org/wiki/Cardiac_cycle

   Assuming a healthy heart and a typical rate of 70 to 75 beats per minute, each cardiac cycle, or heartbeat, takes about 0.8 second to complete the cycle. [ 2 ] [ 3 ] Duration of the cardiac cycle is inversely proportional to the heart rate.
