Master of Science in Exercise and Sport Science (MSESS) Thesis Proposal Oral entitled, A Comparison of computer Workstation Postures: Dynamic Sitting, Traditional Sitting and Standing, by Andrew Cardenas, will take place Friday, Nov. 16 at 1 p.m. in the Kinesiology Building, 208. 

Abstract:  This study will examine the biomechanical and neuromuscular responses to a scheduled dynamic seating protocol as compared to traditional seating and standing workstation use.  Twenty healthy participants (10 male, 10 female) will perform a computer task at a traditional seated workstation, a dynamic seated workstation, and a standing workstation for a period of 30 minutes per workstation. The dynamic seated workstation will have participants actively plantarflex and dorsiflex the ankles in a “stepping” motion to the sound of a metronome operating at 40 beats per minute. The traditional seated and standing workstation will have participants sit or stand, respectively. The participants will have muscle activity recorded by electromyography (EMG); haemodynamics of the lower limb recorded by Near Infrared Spectroscopy (NIRS); changes in spinal posture recorded by accelerometers; changes in seat pan, seat back and standing pressure distribution recorded by pressure mats, and subjective discomfort data recorded by ratings of perceived discomfort (RPD) for each 30 min collection period. Statistical analysis will be conducted by using repeated measures analysis of variance for within task and between-workstation comparisons. A Tukey’s post hoc testing will be calculated for any significant findings.
