Which classification of motor skills involves the use of large muscle groups?

The classification of motor skills that involves the use of large muscle groups is gross motor skills. These skills are characterized by movements that engage the muscles of the arms, legs, and torso, allowing for actions such as running, jumping, and lifting. Gross motor skills are fundamental in physical activities and sports, as well as in daily tasks requiring significant body movement.

In contrast, fine motor skills involve smaller muscle groups and are necessary for tasks requiring precision and coordination, such as writing or buttoning a shirt. Complex motor skills often combine various movements and may require coordination of both fine and gross motor skills. Intermediate motor skills, while not a standard classification, would generally refer to movements that fall somewhere between fine and gross motor skills but do not encompass the broader range of large muscle engagement that gross motor skills represent.
