Which of the following is an example of a locomotor skill?

Locomotor skills are movements that enable a person to travel from one place to another. Running is a prime example of a locomotor skill because it involves moving the legs in a coordinated manner to propel the body forward across a distance. This skill is fundamental to many physical activities and sports, allowing individuals to cover ground quickly and efficiently.

In contrast, balancing refers to maintaining the body's center of gravity over its base of support and does not involve a change in location. Jumping, while also a locomotor skill, specifically focuses on the act of leaving the ground and landing again but does not highlight the ongoing movement aspect as clearly as running does. Stretching typically falls under non-locomotor skills since it involves movement that occurs while the body remains in one place. Therefore, running stands out as the quintessential locomotor skill among the given options.
