Análises cinética, cinemática e eletromiográfica das posturas tradicional e sumô no levantamento terra: uma revisão de literatura

Abstract

Investigating the scientific production of a given topic is important to improve research in a field of knowledge in order to also enable the evaluation of its construction. The present study aimed to verify, through a systematic review of the literature, whether different postures of performing the deadlift (traditional vs sumo) lead to significant changes in kinematic, kinetic and electromyographic aspects, as well as whether anthropometric factors are relevant in the preference and/or choice of one or another deadlift style. For that, articles were searched in the PubMed and Scopus digital databases. Data collection was carried out in May and June 2022, using the descriptors "deadlift AND "sumo OR conventional OR traditional" AND "kinematic OR kinetic OR Electromyography OR Anthropometric OR biomechanic"" and the language selection filter English. As inclusion criteria for the study, articles were considered in which the authors compared, from a biomechanical perspective, the traditional and sumo posture of the lifting, using overload and with subjects without recent injuries. Review articles, congress abstracts, editorials and letters were not included in the study; articles or dissertations/theses that did not have the full text in its entirety; and texts that were not in English. After selecting the articles, data regarding the year, authors, analyzed exercises, sample, subjects' experience, type of analysis, musculature and/or structure analyzed and main findings were extracted. The works cited in this research showed that there may be significant differences in muscle activation levels, load position, execution speed, acceleration, total work and joint moment, in the sumo and traditional variations of the deadlift.
