The Max Heart Rate Calculator gives the fastest heart rate that you can achieve during training and exercise, without having any problems. Speed, distance, and training intensity can vary depending on your abilities, training, sports, fitness, and determination.

The maximum heart rate in the person is mostly reduced with years. Therefore, you only need this parameter to use the maximum heart rate calculator. Read in our article below to find out information about healthy heart rate, determine the maximum number of beats, and know the different formulas for calculation.

If you are interested in finding other information from the field of health and sports, explore our site. There are related Heart Score Calculator, Target Heart Rate, or Cycling Heart Rate Zone Calculator.

Heart Rate – What is?

If you know how fast your heart beats during training and exercise, on average, you have a great way to determine whether you are pushing or not.

The only objective way to know that you train to stimulate the peak of your physical conditioning is to record the average heart rate and target zone when you train and then use this maximum battery calculator to measure the effort level.

This type of training is essential for displaying endurance, and this is also useful for any sport that makes you physically active.

Average, healthy, and dangerous heart rates

The normal and healthy number of adult heart rates ranges from 60 to 100 bpm. The table below shows the average normal resting heart rate.

Age range (years)Average resting heart rate (bpm)
18 to 2081.6
21 to 3080.2
31 to 4078.5
41 to 5075.3
51 to 6073.9
61 to 7073.0
71 to 8074.2
Over 8078.1

A well-trained athlete who exercises regularly could have a normal and healthy heart rate closer to 40 BPM. Your perfect number of beats calculates your maximum heart rate and regularly depends on exercise and training.

You can estimate the maximum heart rate by subtracting the age of a person from number 220. For example, for a 35-year-old healthy person, the maximum heart rate calculated would be as 185 BPM.

Target Heart rate

According to our sources and information, the target heart rate during moderate-intensity activity and fitness is 50 to 70 percent of your maximum heart rate. On the other hand, powerful physical activity and exercise should result in about 70 to 85 percent of your maximum. So for 35-year-olds, the target rate is between 93 and 157 BPM (50 to 85 percent of the maximum).

If you plan to exercise above 85% of the maximum number of beats, consult your doctor because it is training and fitness over your limits that the body can handle.

Dangerous Heart rate

If your rate is consistently above 100 BPM or below 60 BPM and you are not an athlete, or if you feel: shortness of breath, unconsciousness, mindlessness, or dizziness. Visit a doctor; these are dangerous heartbeats. It may have consequences for your health. Collect essential information.

Too low or too high heart rate can be dangerous and can be associated with various diseases, e.g., cardiovascular diseases:

Tachycardia – the number of beats more than 100 per minute in the resting phase. It appears in patients suffering from fever, sepsis, anemia, and other conditions.

Bradycardia – occurs in people over 60 years of heart rate (but this can be normal for the individual in excellent form).

Arrhythmia  – heart rate abnormality and rhythm.

Max Heart Rate – Definition?

The max heart rate is the highest number of heartbeats a person can achieve during exercise and fitness without experiencing severe problems. Max heart rate decreases with years. However, it may vary from person to person.

The most accurate method of measurement is through the heart test stress. They are usually performed on a treadmill. In addition, a person is subjected to increasing the intensity of physical activity while monitoring electrocardiography. However, this method is associated with very high costs; therefore, various mathematical formulas for general use have been developed.

Max Heart Rate – Formulas

Heart rates are significantly different between humans and largely depend on their health, physiology, and physical appearance. Researchers and the information they give us are trying to find the most accurate formula.

However, there is still no agreement what the equation should be used. There are dozens of formulas that can be used to calculate. Most are shown below:

Haskell & Fox formula – Most commonly used formula:

HR_{max}=220-Age

Inbar formula:

HR_{max}=205,8-(0,685\times Age)

NS Formula:

HR_{max}=211-(0,64 \times Age)

Oakland nonlinear formula:

HR_{max}=192-(0,007 \times Age^2)

Tanaka, Monahan and Seals Formula:

HR_{max}=208-(0,7 \times Age)

Heart Rate Chart

During moderate-intense activities, the target heart rate is about 50-70% of the max number, while powerful physical activity is about 70-85% of the maximum.

The figures are averages; use them as a general guide. The table shows the target zones and average heart rate.

Do Athletes Have a Higher Max Heart Rate?

The athlete’s heart rate can be considered low compared to the general population. A young, healthy athlete can have a heart rate of 30 to 40 BPM.

This is because exercising strengthens the heart muscle. This allows you to pump a larger amount of blood with every heartbeat. As a result, more oxygen also goes to the muscles.

So the heart rate is fewer beats per minute. However, the rate of athletes can go up to 180 BPM to 200 BPM during exercise.

Max Heart Rate Calculator – How to Use?

Max Heart Rate Calculator uses different formulas. The calculator is designed to select the formula by which we want to determine our value, then enter our years, and then the calculator automatically finds the BPM.

Max Heart Rate Calculator – Example

So, here is an example – if we want to determine the max heart rate of the 38-year-old person using the Haskell & Fox formula.

HR_{max}=220-Age
HR_{max}=220-38 = 182

The maximum heart rate of 38 years old person is 182 BPM.

FAQ

How to calculate max heart rate?

To get the target value, we will easily determine the number of rates through our calculator. Choose which formula you want, enter your age and value is calculated.

Calculate max heart rate by age?

If we use Haskell’s formula and enter my age, that is 25 years, and we get the maximum number of 195 BPM.

What happens if you exceed your maximum heart rate?

It is possible to exceed the upper limit of your zone without any effects until you have coronary arterial disease or have a risk of a heart attack. After that, however, what can cause damage, leaves you with a muscular skeleton injury. Exercising above 85% of your target heart rate can lead to painful joints and muscles.

What is max heart rate?

The max heart rate is the highest heart rate that a person can achieve without serious problems and is expressed in BPM.

Is a higher max heart rate better?

No. The maximum number of heart rates is not a fitness indicator. It does not rise as your fitness improves, nor is it a sign that you are more capable than someone else if you have a larger Max HR than the other.

What’s the lowest your heart can beat?

Doctors consider a low heart rate of 60 BPM and below.

Is 52 bpm while sleeping bad?

For most young people, trained athletes, and people who regularly work, a low heart rate with exercise – is defined as below 60 BPM, and it is normal and healthy. The same goes for sleep. The heart rate usually slows down to 40 to 60 BPM when you sleep. So 52 BPM is quite normal and not bad.
