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] It generally decreases with age. [31]
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 60 bpm. During exercise the rate can be 150 bpm with maximum rates reaching from 200 and 220 bpm. [1]
Normal heart rates vary with age and level of fitness, from infants having faster heart rates (110-150 bpm) and the elderly having slower heart rates. [3] Sinus tachycardia is a normal response to physical exercise or other stress, when the heart rate increases to meet the body's higher demand for energy and oxygen, but sinus tachycardia can ...
Some drugs and medications affect heart rate, meaning you may have a lower maximum heart rate and target zone, says Dr. Steinbaum. “If you have a heart condition or take medication, ask your ...
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 blood pressure that it is pumping against (SBP). It will be a direct indication of the energy demand of the heart and thus a good measure of the energy consumption of the heart.
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 ...

The frequency, type, time, and volume of these exercises should be individually tailored to the patient, prescribed, and conducted by medical professionals and exercise specialists. Pregnant women are also advised not to participate in activities that will increase their heart rate to above 90% of their known maximum heart rate. [15]
