Additionally, a stand-out component was a team competition with a trophy. Winners of the trophy were calculated by using a series of QR codes posted throughout the research site which participants scanned to log breaks from sitting. This study is the first of its kind to use such a competition using QR codes as a tool to reduce and break up sitting time. Interestingly, A-REST did not utilise sit-stand desks, despite these becoming very common in workplace sitting interventions. While feasibility and acceptability of the intervention were the primary goals, workplace and daily sitting, standing and steps, cardiometabolic…
