The Agonist Muscles in the Pike Motion

When performing a pike motion, going from a plank to a pike, which of the following muscles are the agonists?

Select an answer:

a serratus anterior

b rectus abdominis

c sartorius

d latissimus dorsi gastrocnemius

Final answer:

In the pike motion, going from a plank to a pike, the agonist muscles are the rectus abdominis and the serratus anterior.

Explanation:

In the pike motion, going from a plank to a pike, the agonist muscles are the ones responsible for the primary movement. The main agonist muscles involved in this motion are the rectus abdominis and the serratus anterior.

The rectus abdominis is a paired muscle that runs vertically along the anterior abdominal wall. It is responsible for flexing the spine, which is essential in the pike motion. When contracting, the rectus abdominis pulls the ribcage towards the pelvis, creating the bending motion.

The serratus anterior is a muscle located on the lateral surface of the ribcage. It helps in protracting the scapulae, which is necessary for the pike motion. When contracting, the serratus anterior pulls the scapulae forward, contributing to the movement.

Therefore, in the pike motion, the rectus abdominis and the serratus anterior are the agonist muscles responsible for the primary movement.
