Exercising is one of the best activities for the health and fitness of the body. The exercise can be done with low, moderate, and vigorous intensity.
Roxy is likely exercising at <u>vigorous intensity. </u>
Vigorous-intensity can be explained as:
1. Vigorous-intensity exercise is defined as activities done with hard energy and excitement.
2. Vigorous intensities are defined as the activities whose value is greater or equal than METS. The amount of oxygen required in vigorous exercise is maximum.
3. Some of the examples of vigorous exercises examples are swimming, running, aerobics, jumping ropes, and gymnastics. Thus, Roxy is unable to talk to Hector, because she is consuming the maximum amount of oxygen after vigorous activity.
Thus, the correct answer is Option C.
