Formula to calculate maximum heart rate is :

  • A.RHR + MHR
  • B.120 + Age ÷ Height
  • C.220 - Age
  • D.\(\frac{\text{Height (cm)}}{\text{Weight}} \times \text{HR}\)

Answer: C

The usual formula is 220 - Age.

Maximum heart rate falls by roughly one beat per minute for each year of age, and the common estimate subtracts the age in years from 220. A 30-year-old, for example, has an estimated maximum of 190 beats per minute. This figure is the basis of training-zone calculations such as the Karvonen method.

RHR + MHR adds the resting heart rate to the very quantity being calculated, and the other two expressions bring in height and weight, which do not determine maximum heart rate.
