Office workers often experience occupational musculoskeletal disorders. The aim of the current systematic review was to investigate the effectiveness of workplace exercise intervention on the oldest age group of office workers who have been reported in the literature so far, in terms of workability and well-being. Randomized Controlled Trials were used and the methodological guidelines of PRISMA were followed. The keywords used were: office workers, older, exercise intervention, workplace, microbreaks, workability and well-being. The databases searched were: PubMed, PEDro, ResearchGate, CINAHL, PsychINFO and Science Direct. PROSPERO ID: CRD42022329656. Five studies (total number of participants: 1190, mean age: 46,4) met the inclu-sion criteria. Their quality was deemed to be moderate to high, according to PEDro and MPSER scales. Workplace interventions of gradually increased strengthening and moderate stretching exercises, isometric positioning and postural reminders, either with or without supervision, result in decreasing musculoskeletal pain, disability, sick-leave from work and in the improvement of quality of life and physical activity of the middle-aged office workers, without negative impact on their workability. Despite the worldwide aging workforce, there is a knowledge gap due to research absence in the field of microbreak exercise interventions in the group of older office workers.
