Profile of the Brazilian Jiu-Jitsu fighter, variables, techniques and instruments for measuring sports performance: A scoping review

Abstract

Aims:To verify a Brazilian Jiu-Jitsu fighter profile studied in the literature and to characterize the variables, techniques and instruments for measuring sports performance. Methods:The review was carried out according to the declaration criteria PRISMA, considering studies between the years 2010 and 2020 in the SportDiscus, PubMed/Medline, SCOPUS, LILACS, Dialnet and SCIELO. Results: A total of 51 studies were chosen, mostly of Brazilian origin (82.4%).The total sample was integrated by 1,493 fighters (98% men), with an average age of 27.1 years.The most assess variables were the physiological (24 studies) and the physical (13 studies). Of them, the most analyzed were the lactate and grip force, respectively.The assessment instruments most used were the Borg Rating of Perceived Exertion for the physiological variables (13 studies), the dynamometry for the physical variables (13 studies), and the weight scale for anthropometric and nutritional variables (15 studies). Conclusions: It has been generated a Brazilian Jiu-Jitsu fighter profile. The most frequently studied variables were the physiological and physical.The most assessment instrument used were the weight scale, dynamometry and Borg Rating of Perceived Exertion. Moreover, there are few studies that perform measurements in real time, in female fighters, in Brazilian Jiu-Jitsu fighters and who report the fighter style.
