Sit-to-Stand Desk Converters Decrease Self-reported Workplace Sedentary Time and Improve Perceived Productivity in Office Workers.

Abstract

The workplace is often a site of excessive sedentary time (ST). This study evaluated the effects of a 4-week standing desk intervention on ST, fatigue, and productivity in office workers and students. This was a 4-week intervention with 18 office workers (40 ± 13 years, 15 females, body mass index = 22.9 kg/m 2 ) and 15 students (21 ± 2 years, 10 females, body mass index = 26.1 kg/m 2 ). ST was measured using the Physical Activity and Sedentary Behavior Questionnaire, and desk perceptions and fatigue were assessed via surveys. Office workers reduced workplace ST from 5.5 ± 1.1 to 4.4 ± 1.7 hours per day ( P = 0.01); total ST remained unchanged ( P = 0.97). Students exhibited no changes in ST ( P > 0.19). Office workers reported increased productivity ( P = 0.01) and willingness to use the desk ( P = 0.01). No changes in fatigue were observed for either group ( P > 0.06). Standing desks may reduce workplace ST and improve productivity for office workers but had minimal impact on students' activity or productivity.
