Title A hyperventilation theory of job stress and musculoskeletal disorders
Bibliographic information May 2002, Vol.41, No.5, p.420-432. Illus. 59 ref.
Abstract This article presents a hyperventilation theory of job stress and work-related musculoskeletal disorders based on established principles of breathing and job stress. Hyperventilation refers to a drop in arterial CO2 caused by ventilation that exceeds metabolic demands for O2. Excessive loss of CO2 that results from hyperventilation produces a rise in blood pH which triggers a chain of systemic physiological reactions that have adverse implications for musculoskeletal health, including increased muscle tension, muscle spasm, amplified response to catecholamines, and muscle ischaemia and hypoxia. Hyperventilation is also often characterized by a shift from a diaphragmatic to a thoracic breathing pattern, which imposes biomechanical stress on the neck and shoulder region. The theory provides an innovative framework for understanding how job stress contributes to increasing the risk of musculoskeletal disorders, enabling effective work organization interventions and individual stress-management methods.
