Ergonomics Physiology

Physical ergonomics is about the human body's responses to physical and physiological work prospects. Strain injuries from repetition, vibration, force, and posture are the most common types of issues, and thus have design implications Changes in occupational activities are associated with a gradual replacement of jobs that require much dynamic effort by those that involve static and mental efforts. Classic occupational physiology dealing with systemic changes occurring during a dynamic effort is largely superseded by biochemical and electrophysiological studies of changes in cellular physiology evoked by static effort and changes that accompany mental overload and stress.
