The Effects of Lifting Posture on Trunk Muscle Activity.
Proc 36th Ann Mtg --1992 Innovations for Interactions Human Factors Society 1:742-6
Trunk muscle activity of 12 healthy males with coal mining experience was examined while each subject lifted a box under various conditions. The independent variables were four levels of posture (kneeling, stooped under a 1.2-M roof, stooped under a 1.6-M roof, and standing), height to which the box was lifted, and weight of the lifting box. Consequently, many lifting guidelines and recommendations currently in use may not be directly applicable to work being performed in restricted postures.
