Question

Which of the following is true of running but not walking?

A)it’s a good fitness activity for building muscle.
B)there’s a moment when both feet are off the ground.
C)there are special shoes designed just for this activity.
D)it can be used as an aerobic exercise.

Answer 1

The true statement about running, as compared to walking, is that during running there is a moment when both feet are off the ground, which is characteristic of an aerobic exercise.

Step-by-step explanation:

The statement that is true of running but not walking is B) there's a moment when both feet are off the ground. This differentiates running from walking because when you walk, one foot is always in contact with the ground. Running is an aerobic exercise that primarily uses slow-twitch muscle fibers and requires repetitive motion over a longer period of time, making it effective for building cardiovascular endurance. It's important to note that while special shoes may be designed for both running and walking, and both activities can serve as aerobic exercises, the defining difference is the brief phase during running when neither foot is on the ground.
