Answer:
Reesa must perform her training within a heart rate range of 140 and 160 bpm.
Explanation:
Reesa, a 20-year-old athlete, must work on her physical exercises taking into account that her heart rate should never exceed 200 bpm, equivalent to her maximum heart rate (MHR).
MHR is an estimate of the maximum work the heart can do without risk of injury or damage.
The formula for calculating MHR is:
<em>MHR = 220 - age
</em>
In the case of Reesa;
<em>MHR = 220 - 20 = 200 bpm.</em>
Since Reesa wants to train at 70 - 80 % of her MHR, it is calculated:
- <em>MHR70 = 200 X 70% = 200 (70/100) = 140 bpm
</em>
- <em>MHR80 = 200 X 80% = 200 (80/100) = 160 bpm </em>
<u>Reesa should adjust her work so that her heart rate stays between 140 and 160 bpm</u>.
