Accepts healthy volunteers: yes
Allocation: RANDOMIZED
Intervention model: PARALLEL
Primary purpose: PREVENTION

Brief summary: This pilot randomized controlled trial (RCT) will examine the effect of a tailored workplace intervention based on interrupting sitting on work productivity, well-being and cardio-metabolic risk in office workers. The experimental group in the 8-week intervention will be prompted to alternate between sitting and standing while working. The ratio between sitting and standing will begin at 3:1 (two hours per day in an eight-hour day) and increase to 1:1 (four hours per day in an eight-hour day) by the end of the second week of the eight-week intervention.
