Results Level of evidence from 54 high and medium quality studies showed moderate evidence of a positive effect of physical exercise .
Within this domain , there was strong evidence of a positive effect of workplace strength training .
There was limited evidence for ergonomics and strong evidence for no benefit of participatory ergonomics , multifaceted interventions , and stress management .
No intervention domains were associated with “ negative effects ” .
Conclusions The evidence synthesis recommends that implementing strength training at the workplace can reduce MSD  among workers with physically dem and ing work .
In regard to workplace ergonomics , there was not enough evidence from the scientific literature to guide current practice s. Based on the scientific literature , participatory ergonomics and multifaceted workplace interventions seem to have no beneficial effect on reducing MSD among this group of workers .
Purpose This systematic review investigates the effectiveness of workplace interventions to rehabilitate musculoskeletal disorders ( MSDs ) among employees with physically dem and ing work .
Does an Exercise Intervention Improving Aerobic Capacity Among Construction Workers Also Improve Musculoskeletal Pain, Work Ability, Productivity, Perceived Physical Exertion, and Sick Leave?: A Randomized Controlled Trial
Objective : To investigate whether an exercise intervention shown to increase aerobic capacity , would also lead to less musculoskeletal pain ; improved work ability , productivity , and perceived physical exertion ; and less sick leave . Methods : Sixty-seven construction workers were r and omized into an exercise group training 3 × 20 minutes per week and a control group . Question naires and text messages were completed before and after the 12-week intervention . Results : No significant changes were found in musculoskeletal pain , work ability , productivity , perceived physical exertion , and sick leave with the intervention . Question naires and text messages provided similar results of pain and work ability . Conclusions : Although the intervention improved aerobic capacity , it was not successful in improving musculoskeletal pain and other work-related factors . A detectable improvement presumably requires a more multifaceted intervention , larger sample size , or longer follow-up . Text messages may be a convenient data - collection method in future studies
