When performing the Pike on the Pilates Chair, what specific role do the scapular stabilizers play in supporting the inversion and maintaining upper body integrity against the downward force of gravity?

When performing the Pike on the Pilates Chair, the body assumes an inverted position where the hips are higher than the head, and the arms are pressing down on the chair pedals to lift and hold the body. In this exercise, the downward force of gravity acts significantly on the inverted torso and legs, attempting to pull them further towards the floor, placing immense strain on the shoulder girdle. The scapular stabilizers, a group of muscles that originate on the axial skeleton (spine and ribs) and insert onto the scapula (shoulder blade), play a critical role in supporting this inversion and maintaining upper body integrity against gravity. Key scapular stabilizers include the Se....
