Pilates Anatomy and Biomechanics Flashcards

Which muscle group is primarily referred to as the 'powerhouse' in Pilates?

Answer: Core abdominals, pelvic floor, and spinal extensors

The Pilates powerhouse encompasses the deep core muscles including the transversus abdominis, pelvic floor, and spinal extensors.

What is the primary function of the transversus abdominis in Pilates exercise?

Answer: Deep core stabilization

The transversus abdominis acts as a natural corset, providing deep core stabilization before limb movement occurs.

In Pilates, 'neutral spine' refers to which position?

Answer: The natural curves of the spine maintained without exaggeration

Neutral spine preserves the natural lordotic and kyphotic curves of the spine, reducing compressive forces on the discs.

Which plane of movement involves forward and backward body movements such as spinal flexion and extension?

Answer: Sagittal plane

The sagittal plane divides the body into left and right halves, encompassing all anterior and posterior movements like flexion and extension.

What is the role of the multifidus muscle in Pilates movement?

Answer: Segmental spinal stability and extension

The multifidus runs along the spine and provides segmental stabilization, protecting the vertebrae during movement.

Which joint action occurs when the arm is lifted laterally away from the body?

Answer: Abduction

Abduction describes movement of a limb away from the midline of the body, as seen when raising the arm to the side.
