Answer:
Becky’s THR would be between 157 bpm and 190 bpm during the physical activity.
Explanation:
From the given information;
Since Becky is 16 years old, in order to evaluate the MHR, we deduct the age from 220.
Therefore, the evaluation of the maximum age-related heart rate MHR = 220 - 16 = 204 beats per minute
We are being told that she then multiplies her MHR by 77% and 93%.
i.e
77% level: 204 × 0.77 = 157 bpm
93% level : 204 × 0.93 = 190 bpm
The evaluation indicates that the vigorous-intensity physical activity of Becky at 16 years old will need the target heart rate to remain between 157 bpm and 190 bpm during the physical activity.
