How is max heart rate estimated?

Max heart rate (MHR) is commonly estimated using various formulas, the most well-known being the "220 minus age" formula. This formula suggests that your maximum heart rate is 220 beats per minute (bpm) minus your age. For example, for a person who is 30 years old, their estimated max heart rate would be 190 bpm (220 - 30).

However, it's important to note that this formula is a very rough estimate and may not be accurate for everyone. Additionally, there's significant variability among individuals, and factors such as fitness level, genetics, and overall health can influence max heart rate.

Another common formula used to estimate max heart rate is the Tanaka formula:

Max HR=208−(0.7×age)Max HR=208−(0.7×age)

Again, while this formula is another tool for estimation, it's not universally accurate for everyone.

For more accurate results, especially for athletes or those engaging in regular exercise, a stress test conducted by a healthcare professional can provide a more precise measurement of max heart rate. During a stress test, your heart rate is monitored while you exercise, typically on a treadmill or stationary bike, allowing for a more personalized assessment.
