Does the use of standing 'hot' desks change sedentary work time in an open plan office?
ABSTRACT This study assessed the use of standing 'hot' desks in an open plan office and their impact on sedentary work time.
Australian employees (n=11; 46.9 [9.8] years; BMI 25.9 [3.5 kg/m(2)]) wore an armband accelerometer for two consecutive working weeks (November-December 2010). In the second week, employees were encouraged to use a pod of four standing 'hot' desks to stand and work as often as possible. Desk use was recorded using time logs. The percentages of daily work time spent in sedentary (<1.6 METs), light (1.6-3.0 METs) and moderate+ (>3 METs) intensity categories were calculated for each week, relative to the total daily time at work. Paired sample t tests were used to compare weekly differences.
Employees spent 8:09 ± 0:31h/day at work and 'hot' desk use ranged from zero to 9:35 h for the week. There were no significant changes in mean time spent in sedentary (difference of -0.1%), light (difference of 0.8%) and moderate+ (-0.7%) intensity categories. However, individual changes in sedentary work time ranged from -5.9 to 6.4%.
Volitional use of standing 'hot' desks varied and while individual changes were apparent, desk use did not alter overall sedentary work time in this sample.

- "In recent years, sit-stand workstations have been evaluated with respect to their potential to reduce sedentary time as they provide the most elementary form of 'not sitting' during on-going work. While Alkhajah et al. (2012) report a significant reduction in sedentary time at the workplace following the introduction of a personal sit-stand workstation, Gilson et al. (2012) did not find a significant change in proportion of work time spent in sedentary behaviour after fitting a pod of four height adjustable desks into the centre of an open plan office space. Alkhajah et al. also evaluated acceptability, showing a strong preference of the users (83%) not to return to their old workstation set-up after three months of using the sit-stand workstation. "
ABSTRACT: Sedentary work entails health risks. Dynamic (or active) workstations, at which computer tasks can be combined with physical activity, may reduce the risks of sedentary behaviour. The aim of this study was to evaluate short term task performance while working on three dynamic workstations: a treadmill, an elliptical trainer, a bicycle ergometer and a conventional standing workstation. A standard sitting workstation served as control condition. Fifteen Dutch adults performed five standardised but common office tasks in an office-like laboratory setting. Both objective and perceived work performance were measured. With the exception of high precision mouse tasks, short term work performance was not affected by working on a dynamic or a standing workstation. The participant's perception of decreased performance might complicate the acceptance of dynamic workstations, although most participants indicate that they would use a dynamic workstation if available at the workplace.Applied Ergonomics 06/2014; 45(6).

- "The 5.3% difference in overall sitting time observed equates to about 19 min over a 6-h shift. Similar modest changes to sedentary behavior (range À6e6%) were reported in the pilot study by Gilson et al. (2012). Whilst much greater reductions in workplace sitting (w40%) were recently demonstrated in the pilot study introducing a height adjustable device to desks of public health researchers Table 1 Age, sex, body mass index (BMI), weekly hours worked and length of observation of participants with valid inclinometer data, according to desk type.

ABSTRACT: OBJECTIVE: To investigate whether or not use of sit-stand desks and awareness of the importance of postural variation and breaks are associated with the pattern of sedentary behavior in office workers. METHOD: The data came from a cross-sectional observation study of Swedish call centre workers. Inclinometers recorded 'seated' or 'standing/walking' episodes of 131 operators over a full work shift. Differences in sedentary behavior based on desk type and awareness of the importance of posture variation and breaks were assessed by non-parametric analyses. RESULTS: 90 (68.7%) operators worked at a sit-stand desk. Working at a sit-stand desk, as opposed to a sit desk, was associated with less time seated (78.5 vs 83.8%, p = 0.010), and less time taken to accumulate 5 min of standing/walking (36.2 vs 46.3 min, p = 0.022), but no significant difference to sitting episode length or the number of switches between sitting and standing/walking per hour. Ergonomics awareness was not associated with any sedentary pattern variable among those using a sit-stand desk. CONCLUSION: Use of sit-stand desks was associated with better sedentary behavior in call centre workers, however ergonomics awareness did not enhance the effect.Applied ergonomics 12/2012; 44(4).

- "Active seats, for example, support dynamic sitting by adapting to the natural dynamic processes of the human body . Heightadjustable desks promote increased standing and offer the opportunity to work in a variety of postures that can't be achieved while sitting . The interaction with vertical surfaces (e.g., large-scale whiteboards) has the potential to promote activity through spontaneous movements such as stretching and bending. "

ABSTRACT: Work-related musculoskeletal disorders have become one of the most common chronic diseases of modern society. In this paper, we address the problem of physical inactivity in the context of office work and we introduce a new concept of working “in-motion” with high potential to reduce prolonged sedentary behavior and related degenerative phenomena. We promote a paradigm shift in workplace design towards an integrated supportive environment that provides opportunities for office workers to seamlessly change between different work environments. Based on that, we discuss associated opportunities and challenges for HCI design to encourage people for the adoption of a physically active work process in a more natural way.CHI 2012 Extended Abstracts, Austin, TX, USA; 05/2012
