Which term best describes maintaining a straight body line to prevent twisting during movement?

• A. Postural supports
• B. Alignment
• C. Gravity
• D. Efficiency

Answer: (B)

Maintaining a straight body line during movement is about alignment—the way head, spine, pelvis, and limbs line up so they move as a coherent unit. When alignment is correct, forces travel through the joints in a balanced way, preventing twisting and reducing uneven loads on muscles and tissues. This keeps balance, minimizes compensatory twisting, and makes movement more efficient. The other terms don’t describe this positioning: postural supports are devices that help hold posture, gravity is the external force acting on the body, and efficiency is about how much energy movement costs rather than the position of the body itself.
