In footwork 4, which muscles are specifically targeted to maintain plantar flexion?

In footwork 4, the primary focus is on maintaining plantar flexion during the movement. The gastrocnemius and soleus muscles are specifically targeted in this exercise. The gastrocnemius, which is the larger calf muscle, plays a crucial role in performing plantar flexion by allowing the foot to point downward. The soleus, located underneath the gastrocnemius, also contributes significantly to this action, especially when the knee is bent. Together, these muscles work to stabilize the ankle joint and facilitate the movement necessary for achieving proper alignment and control in footwork exercises.

Engaging these muscles effectively assists in enhancing strength and coordination in the lower legs, which is essential for various pilates movements. The other listed muscle groups, such as the quadriceps and hamstrings, primarily influence knee flexion and extension rather than foot positioning. Similarly, the deltoids and biceps are not involved in lower limb movements, and the core and obliques focus more on trunk stability rather than plantar flexion. Thus, option A accurately identifies the muscles involved in maintaining plantar flexion during footwork 4.
