The maximum heart rate (MHR) is the rate at which the human heart of a given person reaches the highest demands. At rest, the heart rate is about 60 to 80 beats per minute.
Ther's two ways to calculate the maximum heart rate, the most used method is:
MHR = 220 - age
So, for Mary: MHR = 220 - 14 = 206 <span>beats per minute (bpm)
The second method:
MHR (2) = 217 - (0.85 *age)
For Mary:
</span>MHR (2) = 217 - (0.85 *14) = 205 beats per minute (bpm)
We can conclude that the two methods give approximately the same result, but it can differ if we compare them with an elderly person.
Now we can calculate Mary's target heart rate:
Target heart rate = MHR * 50% = 206 * 0.5 = 103 beats per minute (bpm)
Mary's target heart rate is 103 beats per minute (bpm).
The correct answer is:
<h3>C. Avoiding Travel Vaccinations</h3><h3>Explanation:</h3>

Intuition might tell us that rough surfaces on clothing would inhibit the speed of an Olympic athlete. It is not true in some cases because rough clothing could not inhibit the performance of an athlete. If the athlete however had the experience first hand while during practice, in wearing such rough outfits then it would not inhibit his performance during his competition. But, if during the competition, he suddenly had to wear a smooth clothing, then he would have a hard time dealing with it during his competition because it is not the one that he had his practice on. So in short, it all boils down on how people adapt to these things and how well they can execute certain things that are not common to everybody. Maybe for some, if they had the time to practice using smooth clothing then it would not be a problem with promoting with their speed.
