OBJECTIVE
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.
METHODS
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.
RESULTS
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).
CONCLUSIONS
Standing desks may reduce workplace ST and improve productivity for office workers but had minimal impact on students' activity or productivity.
目的
工作场所常常是久坐时间过长的地方。本研究评估了为期4周的站立式办公桌干预对上班族和学生的久坐时间、疲劳及工作效率的影响。
方法
这是一项为期4周的干预研究，涉及18名上班族（年龄40±13岁，15名女性，体重指数=22.9kg/m²）和15名学生（年龄21±2岁，10名女性，体重指数=26.1kg/m²）。使用体力活动与久坐行为问卷测量久坐时间，并通过调查评估对办公桌的看法和疲劳程度。
结果
上班族将工作场所的久坐时间从每天5.5±1.1小时减少至4.4±1.7小时（P=0.01）；总久坐时间保持不变（P=0.97）。学生的久坐时间未发生变化（P>0.19）。上班族报告工作效率提高（P=0.01）且使用该办公桌的意愿增强（P=0.01）。两组的疲劳程度均未出现变化（P>0.06）。
结论
站立式办公桌可能会减少上班族在工作场所的久坐时间并提高工作效率，但对学生的活动或工作效率影响甚微。
