Description
Summary:Objectives This study aimed to investigate the energy expenditure of common office-based tasks. The objectives were to: (a) test the classification of tasks as sedentary or light-intensity physical activity and (b) compare the energy expenditure of tasks under two postural conditions (sitting and standing). Background The sedentary nature of office work has been highlighted as a health risk, and strategies to reduce sedentary behavior at work have been developed. However, there is limited evidence to guide the utilization of sit-stand workstations in the workplace for metabolic health benefits. Method A repeated measures laboratory-based study compared the energy expenditure of common office tasks in sitting and standing using indirect calorimetry (n = 22). Four standardized tasks (sitting/standing quietly, reading, typing, sorting paper) under two postural conditions (sitting, standing) were performed in a randomized order. Results The mean energy expenditure for all tasks in sitting and standing was
