Building For The Future: A Systematic Review Of The Effects Of Eccentric Resistance Training On Measures Of Physical Performance In Youth Athletes, Thomas E. Bright, Matthew J. Handford, Peter Mundy, Jason Lake, Nicola Theis, Jonathan D. Hughes

Research outputs 2022 to 2026

Background:

Eccentric resistance training is recognised as an effective stimulus for enhancing measures of muscular strength and power in adult populations; however, its value in youth athletes is currently not well understood.

Objective:

The aim of this systematic review was to critically appraise the effects of eccentric resistance training on measures of physical performance (i.e. muscular strength, jump, sprint and change of direction) in youth athletes 18 years of age and under.

Methods:

Original journal articles published between 1950 and June 2022 were retrieved from electronic search engines of PubMed, SPORTDiscus and Google Scholar’s advanced search option. Full journal articles …

Physical And Technical Demands Of Offence, Defence, And Contested Phases Of Play In Australian Football, Christopher Wing, Nicolas H. Hart, Fadi Ma’Ayah, Kazunori Nosaka

Research outputs 2022 to 2026

Background: This study compared the physical demands and effect of field location for different phases of play (offence, defence and contested), and examined the physical and technical demands of successful and unsuccessful phases of play during Australian Football matches. Methods: Global positioning system (GPS) and technical performance data were collected from 32 male Australian Football players in one club over 19 games in the 2019 season. The GPS data was aligned with phases of play acquired using Champion Data. Linear mixed models were used to detect differences between phases of play and field location which were further contextualized using Cohen’s …

The Effects Of A Unilateral Strength And Power Training Intervention On Inter-Limb Asymmetry And Physical Performance In Male Amateur Soccer Players, Francesco Bettariga, Luca Maestroni, Luca Martorelli, Paul Jarvis, Anthony Turner, Chris Bishop

Research outputs 2022 to 2026

The aims of this study were (a) to investigate the effects of a unilateral training program in reducing inter-limb asymmetry in male soccer players; (b) to explore such effects on measures of physical performance and unilateral inter-limb asymmetry. Twenty-four soccer players, randomly assigned to a 6-week unilateral strength and power training (UNI) (n = 12) or a control group (CON) (n = 12), performed single countermovement jump (SLCMJ), single leg broad jump (SLBJ), single leg drop jump (SLDJ), 10-m sprint, and 505 change of direction (COD) speed test. Raw jump scores revealed small to large improvements in SLCMJ, SLBJ, and …

Optimum Power Loads For Elite Boxers: Case Study With The Brazilian National Olympic Team, Irineu Loturco, Chris Bishop, Rodrigo Ramirez-Campillo, Felipe Romano, Mateus Alves, Lucas A. Pereira, Michael Mcguigan

Research outputs 2014 to 2021

The purpose of this case study was to examine the effects of a resistance-training program based on the optimum power loads (OPL) method on neuromuscular performance of Olympic boxing athletes during preparation for the Rio-2016 Olympic Games. Twelve elite amateur boxers from the Brazilian National Olympic Team participated in this study. Athletes were assessed at four time-points, over two consecutive competitive seasons. In the first season (considered as “control period”), the athletes executed a non-controlled strength-power training program for 10 weeks. In the second season (a seven-week experimental period), the elite boxers performed 14 power-oriented training sessions, comprising bench press …

Validity Of Boston Marathon Qualifying Times, Paul M. Vanderburgh

Health and Sport Science Faculty Publications

Purpose: To assess the validity of Boston Marathon qualifying (BMQ) standards for men and women. Methods: Percent differences between BMQ and current world records (WR) by sex and age group were computed. WR was chosen as the criterion comparison because it is not confounded by intensity, body composition, lifestyle, or environmental factors. A consistent difference across age groups would indicate an appropriate slope of the age-vs-BMQ curve. Inconsistent differences were corrected by adjusting BMQ standards to achieve a uniform percentage difference from WR. Results: BMQ standards for men were consistently ~50% slower than WR (mean 51.5% ± …

Activity Profiles And Demands Of Seasonal And Tournament Basketball Competition, Markus J. Klusemann, David B. Pyne, Will G. Hopkins, Eric J. Drinkwater

Research outputs 2013

Competition-specific conditioning for tournament basketball games is challenging, as the demands of tournament formats are not well characterized. Purpose: To compare the physical, physiological, and tactical demands of seasonal and tournament basketball competition and determine the pattern of changes within an international tournament. Methods: Eight elite junior male basketball players (age 17.8 ± 0.2 y, height 1.93 ± 0.07 m, mass 85 ± 3 kg; mean ± SD) were monitored in 6 seasonal games played over 4 mo in an Australian second-division national league and in 7 games of an international under-18 tournament played over 8 days. Movement patterns and …

The Effect Of Cluster Loading On Force, Velocity, And Power During Ballistic Jump Squat Training, Keir Hansen, John Cronin, Michael Newton

Research outputs 2011

Purpose: The purpose of this study was to investigate the effect of set structure, in terms of repetition work:rest ratios on force, velocity, and power during jump squat training. Methods: Twenty professional and semiprofessional rugby players performed training sessions comprising four sets of 6 repetitions of a jump squat using four different set configurations. The first involved a traditional configuration (TR) of 4 × 6 repetitions with 3 min of rest between sets, the second (C1) 4 × 6 × singles (1 repetition) with 12 s of rest between repetitions, the third (C2) 4 × 3 × doubles (2 repetitions) …
