Question

the entire cool down process should
(1 point)
○ last between 5 and 10 minutes.
○ last between 15 and 20 minutes.
○ allow the heart to gradually increase in rate.
○ allow muscles to gradually increase in temperature.

Explanation:

In physical fitness and exercise science (related to Medicine and Health, a subfield of Natural Science), the cool - down process typically lasts between 5 and 10 minutes. The purpose of cool - down is to gradually lower the heart rate and muscle temperature, not increase them. So the option "last between 5 and 10 minutes" is correct. The option "last between 15 and 20 minutes" is too long for a typical cool - down. The options about increasing heart rate or muscle temperature go against the purpose of cool - down (which is to decrease heart rate and muscle temperature gradually).

Answer:

A. last between 5 and 10 minutes
