When moving an object considering the principles of biomechanics, which of the following statements is incorrect?

• A. Keep your knees straight
• B. Use your legs to lift
• C. Maintain a straight back
• D. Keep the load close to your body

Answer: (A)

Keeping your knees straight while lifting can lead to improper lifting mechanics and increases the risk of injury. When you straighten your knees and hinge at your waist, you place undue strain on your back, which can result in back pain or injury. In contrast, bending your knees allows you to engage your legs, which are stronger muscle groups, enabling you to lift more efficiently and safely. The principles of biomechanics in lifting advocate for using your legs to lift rather than your back, maintaining a straight back to protect spinal alignment, and keeping the load close to your body to reduce leverage and strain on your joints. These practices help to effectively distribute the weight and minimize the risk of injury during manual handling tasks.
