Brief Summary

Prolonged sitting is a risk factor for cardiovascular and musculoskeletal diseases, diabetes, several types of cancer and all-cause mortality. In combination with static and awkward postures, the prevalence of musculoskeletal diseases can increase further. Although the implementation of sit-to-stand or active workstations can help to reduce sitting time, improve physical activity at work and promote health benefits, it might also lead to changes in cognitive functions such as productivity The purpose of this study is to evaluate the mid-term effect of a novel two desk sit-to-stand workplace on sitting time as well as physiological and cognitive parameters for healthy people of working age in comparison to their traditional workplace.

Conditions

Sedentary Lifestyle; Worksite

Keywords

postural changes; Height adjustable desk; Prolonged sitting; Cognitive performance

Outcome Measures

Primary Outcomes (1)

• Daily sitting time

  Changes in sitting time after 23 weeks in the experimental group compared with its own control period and the control group. Measuring methods: International Physical Activity Questionaire (IPAQ); self developed tracking software at the participants' workplace

  baseline and 23 weeks

Secondary Outcomes (1)

• Cognitive performance (composite outcome)

  baseline and 23 weeks

Other Outcomes (1)

• Stress response

  baseline and 23 weeks

Study Arms (3)

Novel workplace - first half

EXPERIMENTAL

Intervention: A novel two-desk sit-to-stand workstation for 23 weeks; provided within the first half of the study. Traditional workstation within the second half of the study.

Other: Workplace consisting of two height-adjustable desks

Novel workplace - second half

EXPERIMENTAL

Intervention: A novel two-desk sit-to-stand workstation for 23 weeks; provided within the second half of the study. Traditional workstation within the frist half of the study.

Other: Workplace consisting of two height-adjustable desks

Control group

NO INTERVENTION

Control group subjects did not encounter any changes in their regular office environments. Traditional workstation for both halves of the study.

Interventions

Workplace consisting of two height-adjustable desks OTHER

Desk arrangements: self-determined by the participants Desk equipment: depending on pre-intervention condition - 1 or 2 screens per desk Build-up: one day prior to the intervention period at the location of the workplace Adjustment: together with the study leader

Novel workplace - first half; Novel workplace - second half
