What best defines gross motor skills in physical activity?

Gross motor skills in physical activity refer to the abilities that utilize large muscle groups. These skills are essential for performing movements such as running, jumping, and swimming. They require the coordination and control of larger body parts, and are fundamental in developing overall physical fitness, balance, and coordination.

In contrast to options that refer to small muscle groups or fine coordination, which are associated with fine motor skills, the focus on large muscle groups is significant when discussing gross motor skills. This distinction is important because gross motor skills are typically involved in physical activities that promote strength and endurance, contributing to overall physical health and athletic performance. Additionally, skills performed without physical effort do not align with the concept of gross motor skills, as such skills require varying degrees of strength and coordination.
