Heart rate calculator

This tool will take into account your sex and age and calculate your maximum heart rate.

Heart is a muscle and like all muscles in your body, its strenght decreases with age. On the other hand just like your muscles can be trained, your heart can be trained as well. How? By doing a mixture of low/high intensity wourkouts like runnig, cycling etc.

What is heart rate

Heart rate is the rhythmic contraction and relaxation of the heart muscle. Heart rate is expressed as number of heartbeats in one minute.

Heart muscle is a muscular pump that pushes blood throughout your body and applies blood pressure on your veins. Read more about blood pressure in this article and refer to blood pressure chart for more information. Right side of the heart pumps blood to the lungs (small bloodstream), left side pumps blood for other parts of the body (grand bloodstream). Heart is made of specialized muscle fibers and it operates rhythmically, without fatigue. Heart muscle cannot be controled by brain.

Measure your maximum Heart rate

Although our calculator is pretty accurate in calculating your maximum heart rate there are still ways to measure your maximum heart rate more accurately.

One way is to measure it in a lab under supervision of a doctor by using professional gear. This is the most accurate measurement, but it costs money.

The other way is to measure your maximum heart rate by yourself. Here is how you do it.

Measure your maximum Heart rate by yourself

Go outside and find a track where you can run freely. You should be perfectly healthy at the time of performing this test as this method can be dangerous.

Gear yourself with a heart rate monitor. If you do not own one, borrow the device from a friend.

Start of by streching your muscles. Then, run for 7 – 10 minutes with moderate pace. After that, increase your intensity every 30 seconds until you reach the intensity you cannot maintain for more than 10 seconds.

When such intensity is reached write down or remember your current heart rate. Add 5 units to this number and there is your maximum heart rate.

So if your maximum heart rate reading at all-out intensity was 185 BPM simply add 5 BPM on top of that. Your maximum heart rate is 190 BPM! Still, this method is not 100% accurate, but this measurement is more reliable than merely subtracting your age from 220.
