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 .
Diet, physical exercise and cognitive behavioral training as a combined workplace based intervention to reduce body weight and increase physical capacity in health care workers - a randomized controlled trial
Background Health care workers comprise a high-risk workgroup with respect to deterioration and early retirement . There is high prevalence of obesity and many of the workers are overweight . Together , these factors play a significant role in the health-related problems within this sector . The present study evaluates the effects of the first 3-months of a cluster r and omized controlled lifestyle intervention among health care workers . The intervention addresses body weight , general health variables , physical capacity and musculoskeletal pain . Methods 98 female , overweight health care workers were cluster-r and omized to an intervention group or a reference group . The intervention consisted of an individually dietary plan with an energy deficit of 1200 kcal/day ( 15 min/hour ) , strengthening exercises ( 15 min/hour ) and cognitive behavioral training ( 30 min/hour ) during working hours 1 hour/week . Leisure time aerobic fitness was planned for 2 hour/week . The reference group was offered monthly oral presentations . Body weight , BMI , body fat percentage ( bioimpedance ) , waist circumference , blood pressure , musculoskeletal pain , maximal oxygen uptake ( maximal bicycle test ) , and isometric maximal muscle strength of 3 body regions were measured before and after the intervention period . Results In an intention-to-treat analysis from pre to post tests , the intervention group significantly reduced body weight with 3.6 kg ( p < 0.001 ) , BMI from 30.5 to 29.2 ( p < 0.001 ) , body fat percentage from 40.9 to 39.3 ( p < 0.001 ) , waist circumference from 99.7 to 95.5 cm ( p < 0.001 ) and blood pressure from 134/85 to 127/80 mmHg ( p < 0.001 ) , with significant difference between the intervention and control group ( p < 0.001 ) on all measures . No effect of intervention was found in musculoskeletal pain , maximal oxygen uptake and muscle strength , but on aerobic fitness . Conclusion The significantly reduced body weight , body fat , waist circumference and blood pressure as well as increased aerobic fitness in the intervention group show the great potential of workplace health promotion among this high-risk workgroup . Long-term effects of the intervention remain to be investigated . Trial registration Clinical Trials.gov :
