Which of the following is not a lift type listed?

• A. Lunge lift
• B. Power lift
• C. Deep Squat lift
• D. Stoop lift

Answer: (A)

This question tests recognition of standard lift classifications used in ergonomics. The typical lift types describe how the body positions itself when moving a load: a deep squat lift involves a deep knee bend with hips well below knee height and the load held close to the body, emphasizing leg drive and a relatively upright spine; a stoop lift uses a largely straight knee and a flexed back, lifting with the spine in flexion; a power lift sits between these extremes, with partial knee bend and a relatively upright spine, relying on both legs and hips. Lunge lift isn’t part of this common set of classified lift types, even though a lunge stance can occur in various tasks. So lunge lift is not a listed lift type in this framework.
