An unsafe lifting technique would involve bending over at the waist and lifting a heavy object from the ground with a straight back, without using the legs to help lift the weight. This puts a lot of stress on the lower back and can lead to injury.
Biomechanically correct lifting involves using proper body mechanics to lift objects safely. This includes keeping the back straight, bending the knees and hips to lower oneself to the object, tightening the core muscles, and using the leg muscles to lift the object. Additionally, using leverage such as handles or straps can help distribute the weight of the object and reduce the strain on the body.
Using biomechanically correct lifting techniques is important to prevent injury and strain on the back and other muscles. Injuries from improper lifting can range from minor muscle strains to more serious injuries such as herniated disks or spinal fractures. By using proper lifting techniques, individuals can reduce the risk of injury and maintain their physical health and well-being.
