Question

moderate-intensity physical activity is characterized by ______.
a. perceived exertion <5 on a scale of 5-10
b. walking speed of 2 ½ to 3 mph
c. walking speed of 3 to 4 1/2 mph
d. walking speed of 4 ½ to 5 mph

Explanation:

To determine the correct answer, we analyze each option based on the characteristics of moderate - intensity physical activity:

• Option a: Perceived exertion < 5 on a 5 - 10 scale is incorrect. Moderate - intensity physical activity typically has a perceived exertion of 5 - 6 on a 5 - 10 scale.
• Option b: A walking speed of 2 ½ to 3 mph is too slow and is more characteristic of light - intensity activity.
• Option c: A walking speed of 3 to 4 ½ mph is consistent with the range for moderate - intensity physical activity.
• Option d: A walking speed of 4 ½ to 5 mph is in the range of vigorous - intensity physical activity.

Answer:

c. Walking speed of 3 to 4 1/2 mph
