Which statement about reducing back injuries indicates correct understanding?

Understanding proper lifting techniques is crucial for preventing back injuries, and the statement regarding not twisting while lifting reflects this understanding accurately. When lifting objects, twisting can place unnecessary stress on the spine, particularly the lower back, leading to potential injuries. Keeping the spine aligned and moving your feet to change directions helps to maintain stability and reduces the risk of strain.

Maintaining a straight posture and engaging your leg muscles while lifting—rather than twisting your body—is essential for protecting the back. Proper technique includes using the legs for strength, keeping the head up, and ensuring the load is close to the body, which facilitates better balance and control.

The other statements do not support safe lifting practices as effectively. For example, keeping legs straight while lifting does not utilize the large muscle groups of the legs, increasing the risk of injury. A narrow base of support compromises balance, making it harder to lift objects safely, and holding heavy objects far from the body increases the load on the back. Each of these factors can contribute to a greater likelihood of experiencing a back injury, highlighting the importance of proper lifting techniques in injury prevention.
