Breaking up workplace sitting time with intermittent standing bouts improves fatigue and musculoskeletal discomfort in overweight/obese office workers

Abstract

Objectives To examine whether the introduction of intermittent standing bouts during the workday using a height-adjustable workstation can improve subjective levels of fatigue, musculoskeletal discomfort and work productivity relative to seated work. Methods Overweight/obese office workers (n=23; age 48.2±7.9 years, body mass index 29.6±4 kg/m 2 ) undertook two, 5-day experimental conditions in an equal, randomised (1:1) order. In a simulated office environment, participants performed their usual occupational tasks for 8 h/day in a: seated work posture (SIT condition); or interchanging between a standing and seated work posture every 30 min using an electric, height-adjustable workstation (S..
