Ergonomics (Lifting And Moving) Bjc

Bending at the knees instead of bending your back when reaching down or squatting down is the correct technique to avoid strain or injury. Bending at the knees helps to distribute the weight evenly and engage the leg muscles, which are stronger and more capable of handling the load. This reduces the stress on the back and prevents potential back injuries. Therefore, the statement is true.

Overreaching many times each day can put excessive strain on the back muscles and spine, increasing the risk of back injury. When we reach beyond our normal range of motion repeatedly, it can lead to muscle imbalances, strain, and even herniated discs. Therefore, it is important to be mindful of our movements and avoid overreaching to prevent back injuries.

All of the mentioned factors contribute to making back injuries more likely. Poor physical condition, weight, and posture can put extra strain on the back, increasing the risk of injury. Stress can also lead to muscle tension and poor posture, further increasing the likelihood of back injuries. Overdoing physical activities or exercises without proper form or technique can strain the back muscles and lead to injury. Similarly, overestimating one's strength and attempting to lift or carry objects beyond their capacity can also result in back injuries. Therefore, all of these factors combined increase the chances of experiencing back injuries.

The statement is incorrect. When lifting, it is important to lift with your legs and not with your back. Squatting down helps to engage the leg muscles and maintain a proper lifting posture, reducing the strain on the back. Lifting with the back can lead to injuries and back pain. Therefore, the correct answer is False.

Twisting is not easier on your back than turning your whole body in the direction you want to go. Twisting puts strain on your spine and can lead to back injuries, while turning your whole body allows for proper alignment and reduces the risk of injury. Therefore, the statement is false.

Pushing a cart actually puts less strain on your back than pulling it. When you push a cart, your body is in a more upright position, allowing your legs and core muscles to bear most of the weight and strain. This position also allows for better distribution of force, reducing the pressure on your back. On the other hand, when you pull a cart, you are more likely to lean forward, putting more strain on your back muscles. Therefore, the statement that pulling a cart puts less strain on your back than pushing it is false.
