Answer:
The correct answer will be option-B
Explanation:
Karvonen is known for his work on coronary heart disease and epidemiology and giving the formula for calculating the target heart rate zone during the training called 220-age formula.
The formula is based on the age and resting heart rate of the trainer. To measure the heart rate first the resting heart rate of a person is measured every fifteen-minute.
Then find age-predicted maximum heart rate by subtracting the age of the person from 220.
The heart rate reserve is calculated then by subtracting the resting heart rate from the maximal heart rate.
Thus, Option-B is the correct answer.
Fatigue is temporary loss of strength and energy resulting from hard physical, MENTAL, or nervous exertion (stress). Hope this helps!
Answer:
147 to 161 bpm
Explanation:
The appropriate formulas are ...
220 - age = maximum heart rate
⇒ 220-32 = 188
Maximum heart rate - resting heart rate = heart rate reserve
⇒ 188 -52 = 136
(Heart rate reserve X training%) + resting heart rate
⇒ 136 × {0.7, 0.8} +52 = {147.2, 160.8}
John's target heart rate range is 147 to 161.
