Effect of Active Workstation on Energy Expenditure and Job Performance: A Systematic Review and Meta-analysis.

BACKGROUND: Recently developed active workstation could become a potential means for worksite physical activity and wellness promotion. The aim of this review was to quantitatively examine the effectiveness of active workstation in energy expenditure and job performance. METHODS: The literature search was conducted in 6 databases (PubMed, SPORTDiscuss, Web of Science, ProQuest, ScienceDirect, and Scopuse) for articles published up to February 2014, from which a systematic review and meta-analysis was conducted. RESULTS: The cumulative analysis for EE showed there was significant increase in EE using active workstation (mean effect size [MES]: 1.47; 95% confidence interval [CI]: 1.22 to 1.72, p<.0001). Results from job performance indicated two findings: (a) active workstation did not affect selective attention, processing speed, speech quality, reading comprehension, interpretation and accuracy of transcription, and (b) it could decrease the efficiency of typing speed (MES: -0.55; CI: -0.88 to -0.21, p<.001), mouse clicking (MES: -1.10; CI: -1.29 to -0.92, p<.001). CONCLUSION: Active workstation could significantly increase daily PA and be potentially useful in reducing workplace sedentariness. Although some parts of job performance were significantly lower, others were not. As a result there was little effect on real-life work productivity if we made a good arrangement of job tasks.
