To examine relationships between Brazilian Jiu Jitsu (BJJ) descriptors (belt rank, experience, gi preference, and fighting style), resistance training (RT) experience, and measures of body composition, strength (maximal handgrip, 3-5-repetition maximum [RM] in barbell glute bridge [GB], prone bench row [PBR], and bench press [BP]), and velocity (GB, PBR, and BP at 7 kg and 30 – 60 % 1-RM), 13 experienced (4.3 ± 3.4 years) BJJ athletes were recruited for this cross-sectional, pilot study. Significant (p < 0.05) Kendall’s tau and Bayesian relationships were seen between belt rank and body fat percentage (τ = − 0.53, BF10 = 6.5), BJJ experience and body fat percentage (τ = − 0.44 to − 0.66, BF10 = 2.6 – 30.8) and …

Changes In Deadlift Six Repetition Maximum, Countermovement Jump Performance, Barbell Velocity, And Perceived Exertion Over The Duration Of A Microcycle, Stuart N. Guppy, Tsuyoshi Nagatani, Wayne C. K. Poon, Kristina L. Kendall, Jason P. Lake, G. Gregory Haff
Research outputs 2022 to 2026
The primary aim of this study was to investigate the stability of the six-repetition maximum (6RM) deadlift over the length of a five-day microcycle and whether the fatigue induced by maximal effort testing detrimentally impacted preparedness. Twelve participants performed four testing sessions, comprising a one-repetition maximum test and three 6RM tests separated by 48 hours. Countermovement jumps were performed before each testing session, and barbell velocity was measured during each warm-up set to assess changes in preparedness. The 6RM deadlift was not statistically different between any of the testing sessions (p = .056; ηp2 = 0.251). Similarly, …
Validity And Reliability Of Methods To Determine Barbell Displacement In Heavy Back Squats: Implications For Velocity-Based Training, Brendyn B. Appleby, Harry Banyard, Prue Cormie, Stuart J. Cormack, Robert U. Newton
Validity And Reliability Of Methods To Determine Barbell Displacement In Heavy Back Squats: Implications For Velocity-Based Training, Brendyn B. Appleby, Harry Banyard, Prue Cormie, Stuart J. Cormack, Robert U. Newton
Research outputs 2014 to 2021
The purpose of this study was to investigate the validity and reliability of methods for determining barbell displacement during heavy back squats. Twelve well-trained rugby union players (mean ± SD 1 repetition maximum [1RM] 90° squat = 196.3 ± 29.2 kg) completed 2 sets of 2 repetitions at 70, 80, and 90% of 1RM squats. Barbell displacement was derived from 3 methods across 4 load categories (120–129, 140–149, 160–169, and 180–189 kg) including: a (a) linear position transducer (LPT) attached 65 cm left of barbell center, (b) 3D motion analysis tracking of markers attached to either end of a barbell, …
