ACGIH Webinar: Controversies on the Benefits of Sitting, Standing, or Hybrid Workplaces

The webinar is in 2 parts.

The first will focus on the musculoskeletal benefits and problems associated with common office work postures such as sitting, standing, or the hybrid perched posture. Seating pros and cons (support, biomechanics, discomfort/pain ) and standing pros and cons (movement, force, biomechanics, discomfort/pain, LBP) on muscle fatigue and edema, varicose vein will be discussed. In addition, possible Interventions (mobility, rest, exercises, antifatigue mats) and some myths will be discussed.

The second part will focus on what is known about prolonged sitting and standing on the cardiovascular system, especially as related to strokes and heart attacks. To some degree, these effects interact with age, sex, exercise status, and obesity. In addition, the effects of prolonged sitting versus alternating sitting with standing, or introducing brief exercise bouts during the day will be discussed.

Learning Objectives:

  • Choices of whole body postures as a function of work requirements and understanding of consequences
  • Persistence of muscle fatigue associated with prolonged postures
  • Possible interventions to reduce the risk of MSDs
  • Understanding cardiovascular risks associated with prolonged sitting and standing
  • Understanding effects of sitting vs alternating sitting/standing on blood pressure and other cardiovascular risk factors.

Bernard Martin, PhD, Dr, Sc

Bernard Martin is an associate professor in the Department of Industrial and Operations Engineering and an affiliate of the department of biomedical Engineering at the University of Michigan. He has an engineering degree in applied physics and electrical engineering (Marseille, France), a PhD in Bioengineering and a Doctorat Es Science from the Université de Provence (Marseille, France). He teaches courses in ergonomics, human performance and engineering systems and neurosensory systems. His research is centered on human sensorimotor systems and the application of such knowledge to performance, rehabilitation and ergonomics. He uses complementary approaches to investigate the role of sensory information in the regulation of sensorimotor activities. Currently his focus is on the understanding of upper limb sensory and motor asymmetries, adaptation of rehabilitation procedures to sensory and/or motor deficits, long lasting muscle fatigue and prevention of musculoskeletal disorders, and prevention of motion sickness.
