Influência das variáveis do treinamento de força na hipertrofia muscular regional: uma revisão sistemática

Abstract

ABSTRACT Strength training (ST) has been widely disseminated due to its physical, sports and general health benefits. Manipulations of variables in strength training serve as a foundation for planning the protocol to achieve a certain objective. As one of the objectives, muscle hypertrophy occurs as a result of different pathways, but mainly due to the stimulus that the skeletal muscle receives through training in a RT protocol. Some studies have shown that the increase in the cross-sectional area (CSA) can occur differently in different muscle regions, characterizing the so-called nonhomogeneous or regional hypertrophy. Regional hypertrophy is characterized by the differentiated increase in AST along the length of the musculature. Faced with the possibilities and the uncertainty about the influence of variables that can cause regional hypertrophy, the objective of this study was to present, through a systematic review, the TF variables that generated regional hypertrophy along the muscle. The present study is a systematic review carried out in the PubMed database, being a criterion for inclusion studies that have a sample with healthy people, that clearly uses some variable of the TF and contains comparatives of regionalized hypertrophy. After identification and screening, 10 articles that fit the study were identified. Articles that did not have consistent comparisons and/or evaluation methods with a low standard of confidence were excluded. Included 3 more gray literature articles from base articles and others, totaling 13 articles. Study quality was assessed using the PEDRro scale. The present study provides a perspective on the occurrence of regional hypertrophy. With the few studies reviewed, it is noted that regionalized hypertrophy is very complex and can be influenced by more than one training variable. There are still some limitations in the review, since most of the studies involve untrained people (men and women), and it may be interesting to expand the audience to verify whether the level of training can influence the results or not. In addition to manipulating other variables so you can define which ones can be used for that purpose. Keywords: Selective Hypertrophy. Non-uniform hypertrophy. Regional hypertrophy.
