Abstract
This paper describes a study examining the effects of posture on back strength and electromyography of eight trunk muscles. Each subject performed a series of 12 back strength exertions while standing and kneeling. Mean and maximum integrated electromyography of right and left erectores spinae, latissimus dorsi, external obliques, and rectus abdominis were collected during each test of back strength. The results of this data will be used by the Bureau of Mines to assist in assessing the stresses of working in restricted work postures in underground mines.
