How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

This study aimed to determine the relationship between collision metrics from a commercially available micro‐sensor technology unit (MST) and the count of collisions coded by expert video analysts in professional rugby union. Forty‐four professional rugby union players wore MST units during match play. We analysed 245 combined data files from 11 co...
Currently, there is a lack of consensus regarding the optimal load with which to expose athletes to during resisted sled sprint training for the purpose of training linear acceleration and sprint performance. We propose that the use of "momentum" is a practical method of determining the optimal load for resisted sled sprint training.
The effects of acute ingestion of caffeine on short-duration high intensity performance are equivocal, while studies of novel modes of delivery and the efficacy of low doses of caffeine are warranted. The aims of the present study were to investigate the effect of acute ingestion of caffeinated chewing gum on repeated sprint performance (RSP) in te...
Global Positioning System (GPS) technology is commonly utilized in team sports, including rugby union. It has been used to describe the average running demands of rugby union. This has afforded an enhanced understanding of the physical fitness requirements for players. However, research in team sports has suggested that training players relative to...
Objectives The mechanisms of hamstring strain injuries (HSIs) in professional Rugby Union are not well understood. The aim of this study was to describe the mechanisms of HSIs in male professional Rugby Union players using video analysis. Methods All time-loss acute HSIs identified via retrospective analysis of the Leinster Rugby injury surveillan...
Background: Rugby union demands a multifaceted approach to training, given the multiple physical and technical attributes required to play the sport. Objectives: The aim of this study is to describe the distribution of training throughout the week and investigate how this may be influenced by match-related factors. Methods: Training load data (sess...
Objectives To evaluate whether differences in physical characteristics (running-related and collision-related metrics) exist between four different professional rugby union competition levels. Design We collected and retrospectively analysed microsensor technology data from players of two professional rugby union clubs that competed across four di...
Background The mechanisms of acute ankle syndesmosis ligament injuries in professional rugby union are not well understood. Aim To describe the mechanisms of acute ankle syndesmosis ligament injuries in male professional rugby union players using systematic visual video analysis. Methods All time-loss acute ankle syndesmosis ligament injuries ide...
Study Design Case series. Objectives To describe ankle syndesmosis ligament injury mechanisms in male professional rugby union players using systematic video analysis. Background Current knowledge on ankle syndesmosis ligament injury mechanisms in male professional rugby union players is limited. Methods and Measures We assessed videos from 8 an...
A number of studies have used global positioning systems (GPS) to report on positional differences in the physical game demands of rugby union both on an average and singular bout basis. However, the ability of these studies to report quantitative data is limited by a lack of validation of certain aspects of measurement by GPS micro-technology. Fur...
The aim of our study was to determine if there is a role for manipulation of g force thresholds acquired via micro-technology for accurately detecting collisions in rugby union. In total, 36 players were recruited from an elite Guinness Pro12 rugby union team. Player movement profiles and collisions were acquired via individual global positioning s...
