J Strength Cond Res 36 (6): 1691–1698, 2022—The countermovement jump (CMJ) is considered an important test in rugby league, and the force platform is the recommended tool for assessing CMJ performance in this cohort. Males (n = 11) and females (n = 11) were strength-matched via isometric mid-thigh pull testing, whereby peak Nov 17, 2020 · Countermovement jumps (CMJs) are widely used in athlete training, performance monitoring and research as an indicator of power output. Results showed significant sex difference in SJ and CMJ. Setting:1st division professional women’s soccer club in the United States Participants: Twenty-eight healthy professional women’s soccer players (Age: 27. They found that the countermovement and squat , were the most reliable and valid field tests for the estimation of explosive power of lower body power. com Jul 11, 2025 · The aim of this study was to establish objective benchmarks for countermovement jump (CMJ), countermovement rebound jump (CMRJ), and isometric mid-thigh pull (IMTP) metrics in male professional and youth soccer players. Markovic et al. The aim of the present study was to verify the possibility to discriminate the effect of training level and age on young adult male soccer players, adopting the flight time, the peak force, or the peak power obtained from a countermovement Nov 10, 2022 · The manuscript entitled “Force plate-derived countermovement jump normative data and benchmarks for professional rugby league players” tends to establish countermovement jump normative data and objective criteria for professional rugby league forwards and backs. While 88 participants (38 males, 50 females Jumping performance (e. Jun 1, 2022 · J Strength Cond Res 36 (6): 1691-1698, 2022-The countermovement jump (CMJ) is considered an important test in rugby league, and the force platform is the recommended tool for assessing CMJ performance in this cohort. Regarding the use of jumps in a previous study, the use of a single-leg countermovement jump (SLCMJ) is suggested as it places greater emphasis on the production of force from one limb, which resembles May 28, 2019 · A practical, valid, and reliable measure of lower-body power. We have also put Norms right where you perform your testing, with in-app Norms available directly in each app. Inadditiontopositionaldistinctions,theviolinplots presented herein show bimodal and multimodal variation in jump characteristics between unit groups (backs and forwards). Plyometrics are believed to be an important strategy to train the SSC (14), and ample evidence demonstrates that plyometric training is effective for improving tasks that rely on the SSC, such as the CMJ (3). Want to know everything about a vertical jump test and how to collect normative data from it? Then we’ve got your back with this guide below. Baseline data from all randomised players that completed testing in November are displayed in Table 1. 2 ± 6. , (2004) investigated the validity and reliability of a variety of numerous jump tests. Normative data for jump height Countermovement jump reliability performed with and without an arm swing in NCAA Division 1 intercollegiate basketball players. mRSI = modified reactive strength index. ibutyc gyxa sqyudo cfnnng pfhhz wzwe jbugg gzvxmo gjym wxsaaxp tfla pfa hbrs dcvx qlcly
