Question

roxy is exercising with a jump rope. although she is standing next to hector, she is having difficulty speaking to him due to her exertion. therefore, it is likely that roxy is exercising at _______. a. low intensity b. moderate intensity c. vigorous intensity d. none of the above please select the best answer from the choices provided.

Explanation:

During vigorous - intensity exercise, the body's demand for oxygen is very high. This causes a large amount of blood to be diverted to the working muscles, and the respiratory and cardiovascular systems are under great stress. As a result, it becomes difficult to speak while exercising because the body is focused on meeting the metabolic demands of the intense activity. In low - intensity exercise, the oxygen demand is low, and a person can usually speak easily. In moderate - intensity exercise, a person can still carry on a conversation, although maybe with a bit more effort than in low - intensity. Since Roxy is having difficulty speaking due to exertion while jump - roping, it is likely that she is exercising at vigorous intensity.

Answer:

C. vigorous intensity
