The amount of force placed on your lower back when you bend over to lift an object can be surprising.
Did you know the average human upper torso weighs approximately 105 pounds? Bending and lifting a 10 pound object actually puts 1,150 pounds of pressure on the lower back. If you are 25 pounds overweight, it adds an additional 250 pounds of pressure on your back.
Given these figures, it is easy to see how repetitive lifting and bending can quickly cause back problems.
Materials that must be manually lifted should be placed at “power zone” height which is located about mid-thigh to mid-chest. Special care should be taken to ensure proper lifting principles are used – bend at the knees, not at the waist to maintain proper spine alignment, avoid twisting the torso and keep the load as close to the body as possible. Carrying loads on one shoulder, under an arm or in one hand creates uneven pressure on the spine.
Think before you lift an object . . . It’s important to know your body’s limitations. It is also important to be aware of your body position when lifting. Take the proper measures to avoid an injury.
