Question: 1 / 400

What action does the tibialis muscle perform at the ankle joint?

Plantarflexion

Dorsiflexion

The tibialis muscle, specifically the tibialis anterior, is primarily responsible for the action of dorsiflexion at the ankle joint. Dorsiflexion occurs when the foot moves upward, reducing the angle between the foot and the front of the leg. This action is essential for activities such as walking and running, as it allows for proper foot clearance during the swing phase of gait.

In addition to dorsiflexion, the tibialis anterior also assists in inversion, which is the inward turning of the foot. While both of these actions are important, the primary movement associated with the tibialis muscle at the ankle joint is dorsiflexion. Understanding the role of this muscle is crucial for personal trainers and fitness professionals as they assist clients with injury prevention and rehabilitation, as well as in developing effective training programs.
