Which muscles are concentrically contracted to maintain plantar flexion in Urdhva Mukha Svanasana (Upward-Facing Dog Pose)?

In Urdhva Mukha Svanasana, or Upward-Facing Dog Pose, the position requires the feet to be extended, which is known as plantar flexion. The primary muscles involved in concentrically contracting to maintain this action are the gastrocnemius and soleus.

The gastrocnemius, being the larger calf muscle, has two heads and plays a crucial role in the plantar flexion of the ankle joint during this pose. It works alongside the soleus, which lies beneath the gastrocnemius and also assists in this flexion. Together, these muscles enable the foot to move downwards away from the shin, which is essential for maintaining stability and alignment in the pose.

In contrast, the other muscle groups listed are not primarily responsible for the action required in Urdhva Mukha Svanasana. For instance, the quadriceps and hamstrings focus on movements in the knee rather than the ankle. The pectorals and triceps are involved in upper body positioning and support rather than foot positioning, while the gluteals and adductors primarily aid in hip movements. Thus, the gastrocnemius and soleus are indeed the key players in maintaining the necessary plantar flexion during this yoga
