Which term describes the use of large muscle groups in activities such as running, punching, or kicking?

• A. Perceptual Time Distortion
• B. Gross Motor Skills
• C. Fine Motor Skills
• D. Condition Yellow

Answer: (B)

The concept being tested is the difference between actions that use large muscle groups versus those that use small, precise muscles. Running, punching, and kicking rely on big movements of the legs, hips, core, shoulders, and arms; these broad, whole-body actions engage gross motor skills. Gross motor skills involve balance, coordination, power, and the ability to move the body as a unit.

Perceptual time distortion isn’t about how the body moves at all; it describes a perceptual phenomenon. Fine motor skills involve small, precise movements using the hands and fingers, not the large, powerful motions described here. Condition Yellow is a security posture term, not a description of muscle groups or movement. So the term that best fits the description of using large muscle groups for whole-body activities is gross motor skills.
