Abstract Background:<\b>
Low energy expenditure during sitting is a risk factor for metabolic disorders. This study assessed whether active furniture, a Back App chair and balance board, increase activity. Methods:<\b>
The volunteers were 12 office workers (women n=10, 42,5±7,6 years, 170±6,7cm, 76,1±14,9kg) who wore an inclinometer (Fibion Inc, Finland) on thigh in a leg strap for seven days at baseline and a testing period. For the testing period the volunteers received a Back App chair (no back rest, an unstable seat) and a Back App balance board (designed for dynamic standing). Whole day sitting, standing, physical activity, and energy expenditure with and without Back App product usage, were compared with paired samples t-test. Results:<\b>
During the testing period volunteers were self-reportedly sitting on their regular chair 545±389 min, sitting on Back App chair 868±484 min, standing 312 ± 237 min and standing on Back App balance board 247±226 min on a total of 4,6±0,7 days. As compared to sitting on a regular chair (1,50±0,29 kcal/min), sitting on Back App chair (+6,1%; 1,59±0,31 kcal/min, P=0,016), standing (10,9%; 1,67±0,11 kcal/min, P<0,001) and standing on Back App balance board (16,2%; 1,75±0,38 kcal/min, P=0,007) increased energy expenditure, with no difference between standing conditions or the whole day results. Conclusion:<\b>
As compared to sitting on a regular chair, sitting on Back App chair and standing on Back App balance board increase energy expenditure. Changes in the whole day sitting and physical activity require other interventions. External funding details A corporate wellness company paid the measurements for Fibion Inc.
