What Is the Definition of "body Mechanics"?

Body mechanics is defined as "the study of proper body movement to prevent and correct posture problems, reduce stress and enhance physical capabilities," according to About.com. Most back problems can be attributed to poor body mechanics.

The Colorado Comprehensive Spine Institute states that proper body mechanics are important when sitting, standing, sleeping, bending, carrying and lifting.The act of lifting places the most strain on the lower back and therefore has the highest risk of injury, according to the Colorado Comprehensive Spine Institute. To reduce the risk of injury, a person should place the load immediately in front, bend the knees and lift with the leg muscles, as stated by the Colorado Comprehensive Spine Institute.
