INTRODUCTION: Prolonged sedentary behavior may be associated with mortality and other health risks. Research shows a correlation between adiposity and uninterrupted sedentary time, supporting efforts for increasing workplace activity. PURPOSE: The purpose of this research was to determine if body composition changed following a 6 month intervention using sit-to-stand workstations (STS). METHODS: Participants included staff and faculty members of the University of Central Oklahoma. Participants (N=31) were randomly assigned to a treatment group (TG; n=16) and a control group (CG; n=15). TG participants given a STS and instructed to stand at least 2 hours during work hours. Dual-energy X-ray Absorptiometry (DXA) was used to determine total mass (lbs.), fat mass (lbs.), lean mass (lbs.), body fat (%), and bone mineral density (g/cm2) at baseline and 6 months of the intervention. A repeated-measures ANOVA was used to analyze data. RESULTS: No significant differences between or within groups were found (p>.05). Effect sizes were minimal. Small improvements occurred in most variables in the TG, but only for lean mass in the CG. Descriptive statistics can be found in Table 1. CONCLUSIONS: Standing for at least 2 h/d may provide modest benefits to body composition. Future research should examine changes over a longer treatment time and more closely monitor actual time spent using the STS.
