TREINAMENTO COM PESOS E PROMO O DA SAúDE EM ADULTOS: UMA REVIS O SISTEMáTICA DA LITERATURA NACIONAL ACERCA DOS MéTODOS EMPREGADOS EM ESTUDOS CIENTíFICOS

The practice of resistance training (RT) has been stimulated by important societies related to sports medicine and prevention/treatment of some diseases of musculoskeletal order and thus their practice for the treatment of chronic diseases has been discussed. However, there are severe limitations in the experimental design of many studies, this limitation creates bias in its application for such purposes. The aim of this study was to analyze, using a model of systematic review of national literature, the methodological quality of the papers used in weight training in adults and thus identify possible gaps in the national literature. A systematic literature review was conducted in an electronic database. The electronic search was performed in the Scientific Electronic Library Online (SciELO). Among the detected items, inclusion criteria were established: (i) original study involving the practice of weight training, (ii) study conducted in Brazil, (iii) is not a review article, (iv) does not involve other age groups, as children and adolescents. The statistical analysis was made using the chi-square test to compare proportions and the Fisher exact test. Among the studies that examined health-related outcomes, 75% used a control group, while only 26.7% of the studies did not analyze health used a control group. Only 47.8% of the studies used the 1RM test to prescribe intensity. Of the 23 articles analyzed only 30.4% used prior to the familiarization training protocol. There are more scientific studies male samples. Finally, our findings support the conclusion that there is a significant lack of discretion in the conduct of national studies involving RT. In addition, there is little national information on the RT to improve health and that this absence is most felt in specific age groups such as children and adolescents.
