Question 1

Which term describes the relationship between the pelvis and lumbar spine affecting ball exercise mechanics?

Accepted Answer

Lumbopelvic rhythm

Answer

Lumbopelvic rhythm describes the coordinated movement between the lumbar spine and pelvis that governs posture and movement efficiency on the stability ball.

Question 2

The diaphragm contributes to core stability primarily by doing what?

Accepted Answer

Increasing intra-abdominal pressure

Answer

When the diaphragm contracts with a breath hold, it increases intra-abdominal pressure, which stiffens the trunk and enhances spinal stability.

Question 3

Which anatomical landmark is used to identify neutral lumbar spine during stability ball seated exercises?

Accepted Answer

Anterior superior iliac spine

Answer

The anterior superior iliac spine (ASIS) position relative to the pubic symphysis helps trainers cue neutral lumbar alignment on the ball.

Question 4

What happens to the base of support when a client shifts from a bench to a stability ball?

Accepted Answer

It decreases, increasing balance demand

Answer

The curved, compliant surface of the stability ball reduces the effective base of support compared to a flat bench, increasing the balance challenge.

Question 5

Which muscle acts as a hip flexor AND a lumbar spine stabilizer, making it highly relevant to stability ball posture?

Accepted Answer

Psoas major

Answer

The psoas major crosses both the lumbar vertebrae and the hip joint, influencing both lumbar posture and hip flexion during ball exercises.
