Your heart runs on electricity — in fact, every single heartbeat is the result of a tiny electrical impulse travelling through your heart muscle. These impulses can be measured using an an electrocardiogram ECG , which is the most reliable and informative measure of your heart rate.
The test is non-invasive, painless, and you can get it at most GP practices and pathology services. Wearable devices such as smartwatches use light , rather than pressure, to measure heart rate. As the volume of small arteries in the wrist transiently increase with each heart beat, the amount of light reflected back to a conductor in the watch changes — and the frequency with which these fluctuations occur is the heart rate.

As an adult, the normal range for resting heart rate is 60 to beats per minute. This applies for anyone over the age of 17 — infants and children have faster heart rates due to their smaller body and heart size. A normal person pumps around five to six litres per minute, and an average person can get up to 20 litres a minute while exercising — athletes can even go as high as When it beats harder and faster, it can grow stronger and more resilient.
When you start your exercise, your muscles will start to work harder and demand more oxygen. This demand will cause sympathetic nerves to stimulate the heart to beat faster and with more force to increase overall blood flow. The sympathetic nerves will also stimulate the veins, causing them to compress. These narrower veins will increase the velocity at which blood flows through your body.
This will ultimately increase the amount of blood returning to the heart. Introduction When you exercise, do you notice that you get out of breath? What about feeling your heart rate—your pulse—increasing? These two changes are not coincidental—they are both important, and natural, reactions of your cardiovascular system to exercise.
From your brain down to your fingers and toes, your body needs plenty of oxygen to keep going. That oxygen is carried through your body in the bloodstream. Blood is pumped through the heart and picks up oxygen as it passes by the lungs.
Let's track your heart kicking it into high gear during exercise. But don't get moving just yet; first we need to count your resting heart rate. Background When you are exercising, your muscles need extra oxygen—some three times as much as resting muscles. This need means that your heart starts pumping faster, which makes for a quicker pulse. Meanwhile, your lungs are also taking in more air, hence the harder breathing.
So, getting out of breath while exercising is just a sign that your muscles are working. The more you exercise, the more efficient your body will be at getting oxygen to your muscles, so you can exercise more without getting out of breath.
