Objectives Assess the validity and feasibility of current instrumented mouthguards (iMGs) associated systems. Methods Phase I; four iMG systems (Biocore-Football Research Inc (FRI), HitIQ, ORB, Prevent) were compared against dummy headform laboratory criterion standards (25, 50, 75, 100 g ). II; evaluated for on-field iMG-triggered events video-verification to determine true-positives, false-positives false-negatives (20±9 player matches per iMG). III; by 18 rugby players, perceptions fit ,...
Abstract Purpose Head acceleration events (HAEs) are a growing concern in contact sports, prompting two rugby governing bodies to mandate instrumented mouthguards (iMGs). This has resulted an influx of data imposing financial and time constraints. study presents computational methods that leverage dataset video-coded match events: cross-correlation synchronisation aligns iMG video recording, by providing playback timestamps for each HAE, enabling analysts locate them footage;...
The aims of this study were to (1) assess the concurrent validity global positioning systems (GPSs) against a radar device measure sprinting force-velocity (F-v) profiles and (2) evaluate interunit reliability 10-Hz GPS devices (Vector S7, Catapult Innovations).Sixteen male elite U18 rugby union players (178.3 [7.6] cm; 78.3 [13.2] kg) participated. Two 50-m sprints interspersed with at least 5 minutes recovery completed obtain input (maximal sprint speed acceleration time constant τ) output...

Background Head-on-head impacts are a risk factor for concussion, which is concern sports. Computer vision frameworks may provide an automated process to identify head-on-head impacts, although this has not been applied or evaluated in rugby. Methods This study developed and novel computer framework automatically classify non-head-on-head impacts. Tackle events from professional rugby league matches were coded as either These included non-televised standard-definition televised...
This study aimed to quantify contact-events and associated head acceleration event (HAE) probabilities in semi-elite women's rugby union. Instrumented mouthguards (iMGs) were worn by players competing the 2023 Farah Palmer Cup season (13 teams, 217 players) during 441 player-matches. Maximum peak linear (PLA) angular (PAA) per-event used as estimates of vivo HAE (HAEmax), linked video analysis-derived analysed using mixed-effects regression. Back-rows had highest number per full-match (44.1...

Identify the frequency, propensity, and factors related to tackle events which result in contact with head elite-level women's rugby league.Prospective video analysis study.Video footage from 59 Women's Super League matches were analysed (n = 14,378 events). All coded as no or contact. Other independent variables included: area contacting head, impacted player, concussion outcome, penalty round of competition, time match team standard.There 83.0 ± 20.0 (propensity 304.0/1000 events) contacts...
Interpreting the physical qualities of youth athletes is complex due to effects growth, maturation and development. This study aimed evaluate effect position, chronological age, relative age on elite male academy rugby union players. 1,424 participants (n = 2,381 observations) from nine Rugby Football Union regional academies prospectively completed a testing battery at three time points, across playing seasons. Anthropometrics, body composition, muscular power, strength, speed, aerobic...
Instrumented mouthguards (iMGs) are a novel technology being used within rugby to quantify head acceleration events. Understanding practitioners' perceptions of the barriers and facilitators their use is important support implementation adoption. This study assessed men's women's union league iMG managers' staff player interest in technology, data use. Forty-six managers (men's n = 20 9 7 10) completed an 18-question survey. Perceived varied across roles with medical reported as having most...
ABSTRACT Objectives Describe head acceleration events (HAEs) experienced by professional male rugby union players during tackle, ball‐carry, and ruck using instrumented mouthguards (iMGs). Design Prospective observational cohort. Methods Players competing in the 2023 Currie Cup (141 players) Super Rugby (66 seasons wore iMGs. The iMG‐recorded peak linear (PLA) angular (PAA) were used as vivo HAE approximations linked to contact‐event data captured video analysis. Using maximum PLA PAA per...
Participation in women’s rugby league has been growing since the foundation of English Super League 2017. However, evidence base to inform remains sparse. This study provides largest quantification anthropometric and physical qualities players date, identifying differences between positions (forwards & backs) playing level (Women’s [WSL] vs. International). The height, weight, body composition, lower strength, jump speed aerobic capacity 207 were quantified during pre-season period....
This study quantified and compared the movement characteristics of elite domestic international netball match-play, including fifteen individual players who compete at both levels. Microtechnology data were collected across 75 matches in a league-wide from (n = 113) competing Netball Superleague (elite domestic) 23) 22 matches. Players categorised according to seven playing positions. Accelerometer-derived variables analysed per whole-match quarter, for absolute (i.e. volume) relative...
Understanding the locomotor characteristics of competition can help rugby league (RL) coaches optimise training prescription. To date, no research exists on women’s RL. The aim was to compare whole match and peak RL at international (RL World Cup [WRLWC]) domestic level (Super League [WSL]). Microtechnology data were collected from 58 players 3-WSL clubs 1-WRLWC team. Participants classified into forwards (n = 30) backs 28). Partial least squares correlation analysis established which...
