For students of 16 years old with resting heart of 65 the HER would by calculate. A, 160 bpm B, 148bpm C, 170bpm D, 145bpm

To calculate the estimated maximum heart rate (HER) for a student of 16 years old with a resting heart rate of 65, you can use the formula:

HER = 220 - Age

Substituting the age of 16 into the equation:

HER = 220 - 16 = 204 bpm

Therefore, none of the options provided (A, B, C, or D) matches the calculated estimated maximum heart rate.

To calculate the estimated heart rate (HER) for a 16-year-old student with a resting heart rate of 65 bpm, you can use the following formula:

HER = Resting Heart Rate + (0.7 * (220 - Age))

Given that the age is 16, we can substitute it into the formula:

HER = 65 + (0.7 * (220 - 16))
= 65 + (0.7 * 204)
= 65 + 142.8
≈ 207.8 bpm

Therefore, the estimated heart rate (HER) would be approximately 207.8 bpm.

Out of the given answer options, none of them match the calculated HER of 207.8 bpm.
