The pulse is the pressure wave you can feel as the pumping heart pushes the blood Ih rough the arteries. According to modern medical science, the pulse gives an indication of the rate and pressure at which the heart is beating apart from the rhythm, character and volume.
In a normal individual, normal pulse rate is between 65 and 85, although it tends to be higher in children and the elderly, up to 100 to 110 beats per minute. Most of the times, the pulse rate changes according to the demand. For example, during and after exercise, the rate increases in order to supply the exercising muscles with more blood and oxygen.
However, those who enjoy physical activity often have a slower pulse rate. Just as their body muscles develop and enlarge, so does their heart muscle, which as an outcome, becomes better conditioned and more efficient.
Consequently, the rate at which it can perform the job of pumping the blood around the body is slower than it would be in a less fit individual. The pulse also increases in response to nervous signals and the release of adrenaline like substances into the bloodstream, during psychological stress, excitement or emotion.
