This online Max Heart Rate Calculator allows you to estimate the maximum heart rate during training without the risk of serious health problems. The calculator uses the five most popular calculation formulas that determine the dependence of this value on age. To calculate the maximum heart rate (Max HR) value choose the appropriate formula and specify the age either using the slider or by entering the data into the calculator field.
What is Maximum Heart Rate?
Maximum heart rate (denoted as Max HR, MHR or HRmax) refers to the highest number of beats your heart can achieve in one minute (beats per minute, or bpm) during intense physical activity. It is a useful metric for understanding your body’s physiological response during exercise and determining your exercise intensity zones. Maximum heart rate varies from person to person and tends to decline with age.
Understanding your maximum heart rate allows you to tailor your workouts and exercise programs to optimize your performance and ensure safety.
Maximum heart rate serves as a reference point to establish target heart rate zones for different types of workouts, such as endurance training, fat burning or high-intensity interval training (HIIT). This information helps you customize your training and achieve specific fitness goals.
Exercising within the appropriate heart rate range helps prevent overexertion and reduces the risk of cardiovascular complications or injury. Staying within a safe heart rate zone allows you to challenge yourself without pushing your body beyond its limits.
Calculation of Maximum Heart Rate
There are several formulas commonly used to estimate maximum heart rate. While these formulas provide a rough estimate, it is important to note that individual variations exist, and the accuracy may vary. Here are some widely known formulas used in our Max Heart Rate Calculator :
• Fox Formula: Max HR = 220 – age
This is the simplest and the most common formula used for calculating max heart rate. It can be applied for both men and women and is usually the formula used by fitness watches and exercise equipment.
Despite its popularity, this formula is not very accurate, especially for older adults. Studies show that the standard deviation of the result is +/- 12-15 beats per minute.
• Tanaka Formula: Max HR = 208 − 0.7×age
It is important to note that this formula is a general estimation and may not be as accurate for highly trained athletes or individuals with specific health conditions.
The Tanaka formula can be applied for both men and women and the standard deviation of the result is +/- 10 beats per minute. This formula is primarily designed for people over age 40.
• Nes Formula: Max HR = 211 − 0.64×age
The Nes formula, also known as the HUNT formula was developed based on data from the HUNT Fitness Study. This formula is said to be better for active men and women. Its accuracy is at the level of the Tanaka formula.
• Gulati Formula: Max HR = 206 − 0.688×age
The Gulati formula was developed specifically for women after it was found that the Fox formula usually overestimates the max heart rate for women. The standard deviation of the result is +/- 11.8 beats per minute.
• Oakland Nonlinear Formula: Max HR = 192 − 0.007×age2
The Oakland nonlinear formula is a more accurate way to estimate maximum heart rate. This formula was developed by researchers at Oakland University in Michigan. The standard deviation of the result is +/- 2-5 beats per minute
How to Use Maximum Heart Rate
Once you have estimated your maximum heart rate, you can use it to help you set safe and effective exercise goals. For example, if you are trying to lose weight, you should aim to exercise at a heart rate that is between 65% and 85% of your Max HR. This is known as the target heart rate zone.
You can also use maximum heart rate to track your progress over time. As you get fitter, your Max HR will decrease. This means that you will be able to exercise at a higher intensity without exceeding your max heart rate.
Additionally, as with any formula or estimation method, it is always recommended to consult with healthcare professionals or fitness experts for a comprehensive assessment of you maximum heart rate and to tailor exercise programs accordingly.
