SUMMARY:

Industry represents, among the various economic sectors, one of the activities with high employability rates in developing countries. The work process involves, in some cases, a great energetic, biomechanical and psychological demand by the workers for the performance of labor actions. Intensification of work or poor structuring can lead to the development of numerous work-related illnesses, such as mental or physical fatigue and skeletal muscle injuries, increasing the temporary or permanent work disabilities. This research will be composed of two studies. The objective of the first was to investigate the effects of ergonomic interventions in the industrial work process in order to reduce the pain on workers in this productive sector, while the second study aims to evaluate the effectiveness of job rotation on fatigue, quality of life, handgrip, pinch force and resistance of the scapular muscles of textile workers. In the first study, was conducted a systematic review of randomized controlled trials with meta-analysis. Were consulted the databases PUBMED, EMBASE, the Cochrane Central Register of Controlled Trials (CENTRAL), Science Direct, Scopus, PEDro, Web of Science, OTSeeker, and PsycINFO. The reference lists were consult manually. We included only studies that were perform interventions in work environment. Two authors independently conducted study selection and bias risk assessment. The analysis of forest plots graphs allowed the evaluation of the heterogeneity of the results of the studies that entered the meta-analysis. We included 18 studies involving 4,871 industry workers. With the results of this study, was evidenced a higher prevalence of the inclusion of physical exercises in the work environment. The studies allowed shoulder pain reduction in workers included in a workplace exercise program (MD -0.45; 95% CI -0.8 to -0.1; p = 0.01; I2 = 76%). Was observed, yet, the reduction of low back pain after ergonomic training and the increase in lumbar function after the practice of resistance exercises at work (MD .59; 95% CI 0.42 to 0.82; p = 0.002; I2 = 18% and MD -9.11; 95% CI -16.30 to -1.92; p = 0.01; I2 = 0%, respectively). With these results, we conclude that physical activity in the industrial workplace can reduce shoulder pain and that resistance exercise can positively influence spine function, as training in ergonomics can reduce low back pain. According with results, we conclude that physical activity in the industrial workplace can reduce shoulder pain and training in ergonomics can reduce low back pain. In the second study, we presents an ergonomic intervention using the job rotation as a strategy to increase quality of life, strength and endurance in the upper limb and reduce fatigue in textile workers. A cluster randomized controlled trial will be used with 48 workers will be distributed among experimental group, which will be included in a job rotation program alternating tasks according to the degree of biomechanical risk, and control group, which will participate in an ergonomic training program. The Swedish Occupational Fatigue Inventory (SOFI) Scale and the SF-36, as well as the measurement of handgrip and pinch strength through the dynamometry and muscular resistance of the trapezius and the anterior serratus (by the Scapular Muscle Endurance test) will evaluate the workers, before and after the interventions. This study intends, through the intervention with the rotation, to produce positive effects on fatigue, quality of life, in addition to strength and muscular endurance in the upper limb of workers in the textile industry.
