Gross motor involvement corresponds to which description?

• A. Large Muscle Groups
• B. Small Muscle Groups
• C. No Obvious Start or Finish
• D. Start and Finish

Answer: (A)

Gross motor involvement means using the larger muscle groups to produce movement of the body as a whole. That’s why the best description is large muscle groups—movements like running, jumping, and throwing rely on muscles such as the legs, hips, and core. In contrast, small muscle groups are used for fine motor skills like writing or manipulating small objects, which is not what gross motor describes. The other two options refer to how a movement is performed over time (whether it has a clear start and finish or continues without one) rather than which muscles are involved, so they don’t describe gross motor involvement.
