The Sex-Specific Effects of Alternating Computer Work Postures in Young Adults

Adults exposed to extended periods of static seated computer work, especially females, have elevated risks of developping musculoskeletal symptoms. However, static standing work is also associated to issues with the musculoskeletal and vascular systems. To address this, alternating between seated and standing postures has been proposed in the form of sit-stand desks; however, their sex-specific impacts on biomechanical, performance and discomfort outcomes remain unclear. As a result, repeated measurements will be taken during a 90-minute computer task, involving both typing and mousing. Muscle activity, head-neck postural angles, visual fatigue, shoulder-neck and lower back discomfort and muscle blood flow will be measured. The project will provide sex-specific quantitative data to help improve computer workstation evidence-based ergonomic interventions which will provide the collaborating company a better understanding of how computer work postures impact the musculoskeletal system, leading to disorders and injuries, which is of utmost importance in a technology-dependent world.
