# Heart Rate Calculator

You can use this Heart Rate Calculator to calculate your maximum and target heart rates. It also creates a heart rate training zone chart based on the Karvonen and Zoladz methods.

## Heart Rate Formulas

The Heart Rate Calculator uses the following formulas:

Maximum Heart Rate (HRmax)

Haskell & Fox, for men : HRmax = 220 - Age

Haskell & Fox, for women : HRmax = 226 - Age

Robergs & Landwehr : HRmax = 205.8 - (0.685 Ã— Age)

Londeree and Moeschberger : HRmax = 206.3 - (0.711 Ã— Age)

Miller et al. : HRmax = 217 - (0.85 Ã— Age)

Tanaka, Monahan, & Seals : HRmax = 208 - (0.7 Ã— Age)

Jackson et al. : HRmax = 206.9 - (0.67 Ã— Age)

Nes, et al. : HRmax = 211 - (0.64 Ã— Age)

Martha Gulati et al., for women : HRmax = 206 - (0.88 Ã— Age)

Gellish, for men : HRmax = 203.7 / (1 + e (0.033 Ã— (Age - 104.3)))

Gellish, for women : HRmax = 190.2 / (1 + e (0.0453 Ã— (Age - 107.5)))

Where e = 2.718282

Heart Rate Reserve (HRreserve)

Heart Rate Reserve (HRreserve) = HRmax - HRrest

Maximum Heart Rate (HRmax) = HRreserve + HRrest

Resting Heart Rate (HRrest) = HRmax - HRreserve

Target Heart Rate (THR)

Karvonen Method : THR = (HRmax - HRrest) Ã— %Intensity + HRrest

Standard Method : THR = HRmax Ã— %Intensity

## Heart Rate Calculator Example

Certainly! Here's an example of using a table to calculate the target heart rate range for different individuals based on their age and desired intensity level:

Assume the following information for three individuals:

Individual Age Maximum Heart Rate (MHR) Resting Heart Rate (RHR) Intensity Level Target Heart Rate Range
Person A 30 190 60 Moderate 114 - 152
Person B 45 175 65 Vigorous 135 - 160
Person C 50 170 70 Light 111 - 128

To calculate the target heart rate range, we need to consider the individual's maximum heart rate, resting heart rate, and the desired intensity level.

Using the given values, we can calculate the target heart rate range for each individual:

For Person A: Target Heart Rate Range = ((MHR - RHR) * Intensity Level) + RHR = ((190 - 60) * 0.6) + 60 = 114 - 152

For Person B: Target Heart Rate Range = ((MHR - RHR) * Intensity Level) + RHR = ((175 - 65) * 0.7) + 65 = 135 - 160

For Person C: Target Heart Rate Range = ((MHR - RHR) * Intensity Level) + RHR = ((170 - 70) * 0.5) + 70 = 111 - 128

Therefore, the target heart rate range for Person A is 114 - 152 beats per minute, for Person B is 135 - 160 beats per minute, and for Person C is 111 - 128 beats per minute.

Using a table allows you to input the age, maximum heart rate, resting heart rate, and desired intensity level for each individual and calculate their respective target heart rate ranges. The target heart rate range is used to guide exercise intensity and ensure individuals are exercising within safe and effective heart rate zones. However, it's important to note that individual heart rate responses to exercise may vary, and this calculation provides a general guideline. It's advisable to consult with a healthcare professional or fitness expert for personalized heart rate recommendations.
