The Biomechanical and Physiological Effect of Two Dynamic Workstations
The aim of this research paper was to investigate the effect, both biomechanically and physiologically, of two dynamic workstations currently available on the commercial market. The dynamic workstations tested, namely the Treadmill Desk by LifeSpan and the LifeBalance Station by RightAngle, were compared to the more conventional seated and standing workstations, through a randomized repeated measures design. Hypothesized was that the use of these dynamic workstations would have an effect on posture, physical activity, energy expenditure and muscular activity. Preliminary results suggest that the dynamic workstation increase physical activity and heart rate compared to the seated workstation.
