In proper body mechanics, which statement is true?

• A. Twisting at the waist is the best way to maintain body alignment.
• B. The narrower a person's base of support, the more stable the person is.
• C. Body mechanics save energy and prevent injury.
• D. Proper alignment of the body means that the two sides of the body should not line up.

Answer: (C)

Maintaining proper body mechanics saves energy and prevents injury. When you move, using your legs to lift or pivot, keeping the load close to your center of gravity, and avoiding twisting the spine helps protect the back and reduces fatigue. You bend at the knees and hips, keep the spine in a neutral alignment, and turn by pivoting the feet rather than twisting the torso. A stable base of support—feet about shoulder-width apart—further enhances balance and safety. Proper alignment usually means the body stays in a straight line so both sides work together symmetrically, not offset. Methods like twisting at the waist increase strain and should be avoided. Thus, the statement about saving energy and preventing injury best captures the benefits of good body mechanics.
