Abstract

Purpose: countermovement jump (CMJ) and squat jump (SJ) are twovertical jumps (VJ) tests used to evaluate the lower limb reactivestrength and the concentric power of the legs [1], respectively.Because the main problem of these two jumps is the lack of standardizationin the test administration [2], the objectives were to gatherinformation and investigate the standard aspects between CMJ and SJprotocols, to identify the most common method used or, if not evident,to design standardized operating execution procedure.Methods: PubMed, Web of Science and Scopus databases were usedfor the electronic search (from January 2010 to June 2018). Originalarticles, systematic reviews and meta-analysis in which CMJ or SJwere used to assess muscular fitness in adolescences were eligible forfurther analysis. English language was imposed like limit. Abstracts,citations, statements and books were excluded. In a second moment,authors analysed the CMJ and SJ methods.Results: A total of 104 studies (CMJ: 102, SJ: 46) met the inclusioncriteria. The description of the CMJ and SJ test methodology washighly diverse within the literature with the protocol developed byBosco et al. [3], the one most used in the studies examined, that wasutilized by five and three different authors, respectively.Conclusions: Because there is no a standardized method for the twojumps, we created new CMJ and SJ protocols based on the positiveaspects of the ones analysed.References1.
