Maintaining a physically active lifestyle is a major concern among individuals. White-collar workers spend most part of their day seated, which can result in a sedentary lifestyle that has inevitable ramifications on health and well-being. PURPOSE: The aim of this research was to see if using a sit-to-stand workstation (STS) had an impact on physical activity habits. METHODS: University employees volunteered and were randomly allocated to a control group (CG; n=9) and an intervention group (IG; n=8) as study participants (N=17). The participants of IG were asked to use a sit-to-stand workstation for 2 hours every work day for 12 months. The long form International Physical Activity Questionnaire (IPAQ) was used to quantify total physical activity (PA), walking PA, and moderate intensity PA in MET·min·wk-1. Measurements of PA were taken at baseline, 6 months and 12 months. Repeated measures analysis of variance (RMANOVA) was used for analysis. RESULTS: One outlier was removed because the individual reported significantly higher MET·min·wk-1more than the rest of the group which does not represent the entire group. According to the analysis, there were no significant differences between PA measured as MET·min·wk-1 at baseline (CG=1098.22±583.72, IG= 2815.90±2011.82), at 6 months (CG=3471.66±3817.05, IG= 2546.31±1225.75) and at 12 months (CG =2783.31±2728.80, IG= 2072.06±1679.93) for both groups(p>.05). CONCLUSION: The IG and CG showed no significant differences implying that a standing workstation intervention may not be enough to improve an individual's physical activity habits. In addition, PA was measured subjectively using a self-reported questionnaire with a 7-day recall period.
