Cervical spine trauma from sport or traffic collisions can have devastating consequences for individuals and a high societal cost. The precise mechanisms of such injuries are still unknown as investigation is hampered by the difficulty in experimentally replicating the conditions under which these injuries occur. We harness the benefits of computer simulation to report on the creation and valid...
Background: Rugby is associated with a high risk of injury, because it is a fullcontact sport with limited use of protective gear. The popularity of rugby in the United States is growing, but the vast majority of epidemiologic studies reports injury data from rugby organizations in other countries. Purpose: To report game and practice injury rates in American collegiate club rugby, specified by...
This study investigated the effect of projection angle on the distance attained in a rugby place kick. A male rugby player performed 49 maximum-effort kicks using projection angles of between 20 and 50°. The kicks were recorded by a video camera at 50 Hz and a 2 D biomechanical analysis was conducted to obtain measures of the projection velocity and projection angle of the ball. The player's op...
Rugby participation in the US is increasing, and with its inclusion in the 2016 Summer Olympics, the increased participation rates are expected to continue. Naturally, as participation increases, so too do rugby-related injuries. The difference in injury patterns with regard to age and gender illustrates differences in how the game is being played. Understanding what accounts for these emerging...
OBJECTIVE To document the incidence of injury in 6-15 year olds playing rugby union, rugby league, and netball, and to identify the common mechanisms, sites, severity, and time of injury. METHODS Cross sectional data were collected by trained observers who watched 258 games of rugby union, netball, and rugby league over a four week period. The condition of the injured participants was monitor...
BACKGROUND There is a paucity of epidemiological data on neck injury in amateur rugby union populations. The objective of this study was to determine the incidence, severity, aetiology and type of neck injury in Australian men's amateur rugby union. METHODS Data was collected from a cohort of 262 participants from two Australian amateur men's rugby union clubs via a prospective cohort study d...
Rugby Union Football is a high-speed contact sport and has a significant incidence of injury. This study evaluated senior rugby players with reference to the anatomical site of injury for each playing position.
We aimed to quantify the ACE I/D and ACTN3 R577X (rs1815739) genetic variants in elite rugby athletes (rugby union and league) and compare genotype frequencies to controls and between playing positions. The rugby athlete cohort consisted of 507 Caucasian men, including 431 rugby union athletes that for some analyses were divided into backs and forwards and into specific positional groups: front...
27 We aimed to quantify the ACE I/D and ACTN3 R577X (rs1815739) genetic variants in elite rugby 28 athletes (rugby union and league), compare genotype frequencies to controls and between 29 playing positions. The rugby athlete cohort consisted of 507 Caucasian men, including 431 rugby 30 union athletes that for some analyses were divided into backs and forwards and into specific 31 positional g...
BACKGROUND In 2012, the South African Rugby Union (SARU) approved a new set of scrum laws for amateur rugby played in the country, to be implemented at the start of the 2013 rugby season. These law changes were primarily based on the relatively high proportion of scrum-related catastrophic injury data collected as part of the BokSmart National Rugby Safety Programme (BokSmart) over the precedin...
