Physical exercise at the workplace reduces perceived physical exertion during healthcare work : cluster randomized controlled trial . BACKGROUND High physical exertion during work is a risk factor for musculoskeletal pain and long-term sickness absence . Physical exertion ( RPE ) reflects the balance between physical work demands and physical capacity of the individual . Thus , increasing the physical capacity through physical exercise may decrease physical exertion during work . This study investigates the effect of workplace-based versus home-based physical exercise on physical exertion during work ( WRPE ) among healthcare workers . METHODS 200 female healthcare workers ( age : 42.0 , body mass index : 24.1 , average pain intensity : 3.1 on a scale of 0 to 10 , average WRPE : 3.6 on a scale of 0 to 10 ) from 18 departments at three participating hospitals . Participants were randomly allocated at the cluster level to 10 weeks of : ( 1 ) workplace physical exercise ( WORK ) performed in groups during working hours for 5×10 minutes per week and up to five group-based coaching sessions on motivation for regular physical exercise , or ( 2 ) home-based physical exercise ( HOME ) performed during leisure time for 5×10 minutes per week . Physical exertion was assessed at baseline and at 10-week follow-up . RESULTS 2.2 ( SD : 1.1 ) and 1.0 ( SD : 1.2 ) training sessions were performed per week in WORK and HOME , respectively . Physical exertion was reduced more in WORK than HOME ( p < 0.01 ) . Between-group differences in physical exertion at follow-up ( WORK vs. HOME ) was -0.5 points ( 95 % CI -0.8 to -0.2 ) . Within-group effect size ( Cohen 's d ) in WORK and HOME was 0.43 and 0.13 , respectively . CONCLUSIONS Physical exercise performed at the workplace appears more effective than home-based exercise in reducing physical exertion during daily work tasks in healthcare workers .
