Abstract
This cross-sectional study examined the lower limb balance, ankle dorsiflexion, orofacial tissue pressure, and occlusal strength of rugby players. Twenty-six participants were divided into groups: rugby players (n = 13) and healthy sedentary adults (n = 13). Participants underwent an analysis of lower limb balance using a composite score (Y-Balance Test). Ankle dorsiflexion was measured using the Lunge Test. The Iowa Oral Performance Instrument was employed to measure orofacial tissue pressure. Bite force was measured with a dynamometer, and T-Scan assessed occlusal contact distribution. Data were analyzed using the t-test (p < 0.05) and ANCOVA with age and weight as covariates, where it is possible to verify that these factors did not influence the results obtained. Significant differences were observed in the balance of the right (p = 0.07) and left (p = 0.02) lower limbs, where rugby players had lower composite scores. There were significant differences in the right (p = 0.005) and left (p = 0.004) lunges, with rugby players showing lower values, as well as lower tongue pressure (p = 0.01) and higher lip pressure (p = 0.03), with significant differences to sedentary participants. There was no significant difference in molar bite force and distribution occlusal contacts between groups. Rugby seems to reduce lower limb displacement, cause ankle hypomobility, lead to changes in orofacial tissues, particularly the tongue and lips. This study is significant for identifying significant differences between rugby players and sedentary individuals, providing new insights into the impact of rugby on health and performance, which can benefit sports training and injury prevention.

Abstract
BACKGROUND Rugby is a sport involving a great number of shoulder collisions. Traumatic stress of the shoulder can weaken the static stabilizers and promote major injuries as dislocation or full-thickness tears of the rotator cuff. The goal of this study is to evaluate the clinical and ultrasonographic dominant shoulder factures in a group of amateur rugby players, with no history of shoulder injuries, and to compare them with those of a control group. METHODS 52 male subjects join in the study: 26 amateur rugby players and 26 subjects, which did not practice rugby or competitive sport. Clinical history was obtained from all subjects, followed by dominant shoulder physical and ultrasonographic exams. RESULTS Rugby players showed a higher prevalence of positive clinical test, suggesting subacromial impingement than control group (p = 0.01). Among rugby group, five players (19,2%) showed positive test for radiculopathy (p = 0,02), and ten players (73,1%) reported shoulder pain needing pain-reliever drugs at list one time in the last six months (p = 0.001). In rugby group, ultrasound exams showed 23,1% degenerative changes and 30,8% tendon calcifications in supraspinatus tendons (p < 0.05). CONCLUSIONS Uninjured dominant shoulder of rugby players shows higher prevalence of clinical and ultrasound changes compare to control. Some rugby players without history of cervical symptoms show positive clinical test of cervical radiculopathy. Clinical and ultrasonographic monitoring of the shoulder can play a role in prevention and knowledge of silent shoulder damage in these athletes.

Abstract
Objectives To investigate the network of stakeholders involved in rugby union research across the globe. Methods Using author affiliations listed on scientific publications, we identified the organisations that contributed to rugby union research from 1977 to 2022 and examine collaboration through coauthorship indicators. We determined the locations and sectors of identified organisations and constructed a collaboration network. Network metrics, including degree centrality and betweenness centrality, are computed to identify influential organisations and measure intersector collaboration. Results There is an increase in scientific knowledge creation and collaboration between organisations for rugby union research over time. Among the sectors, the university, professional sports team and sports governing body sectors exhibit the highest intersectoral and intrasectoral density. Predominantly, influential actors are located in England, Australia, France, New Zealand, Ireland and South Africa. Australian Catholic University, Leeds Beckett University, Stellenbosch University, Swansea University, University College London and the University of Cape Town emerge as influential actors between 2016 and 2022. Conclusions Our study underscores the ongoing growth of scientific knowledge generation in rugby union, primarily led by organisations in tier 1 rugby-playing nations within the university sector. Intersectoral collaboration with sports governing bodies plays a crucial role, acting as a broker between sectors. However, the overall collaboration landscape between and within sectors is low. These results highlight an opportunity for improved collaboration opportunities, as the organisations driving knowledge creation have been identified.

Abstract
There is increasing interest in the potential long-term outcomes of participation in contact and collision sports, driven by evidence of higher rates of neurodegenerative diseases among former athletes. Recent research has capitalised on large-scale administrative health data to examine health outcomes in contact sport athletes. However, there is limited research on outcomes associated with participation in rugby union, a contact sport with a relatively high incidence of head trauma and musculoskeletal injuries. Additionally, there is scope to investigate a greater range of health outcomes using large, population-based administrative data. The Kumanu Tāngata project is a retrospective cohort study that will use linked information from the New Zealand Rugby Register and health records within a comprehensive deidentified whole-population administrative research database known as the Integrated Data Infrastructure. First-class male rugby union players (N=13 227) will be compared with a general population comparison group (N=2 438 484; weighting will be applied due to demographic differences) on a range of mortality and morbidity outcomes (neurodegenerative diseases, musculoskeletal conditions, chronic physical conditions, mental health outcomes). A range of player-specific variables will also be investigated as risk factors. Analyses will consist primarily of Cox proportional hazards models. Ethics approval for the study has been granted by the Auckland Health Research Ethics Committee (Ref. AH23203). Primary research dissemination will be via peer-reviewed journal articles.

Abstract
OBJECTIVE To systematically map the coach education (CE) component of injury prevention programmes (IPPs) for youth field sports by identifying and synthesising the design, content and facilitation strategies used to address competency drivers and behaviour change. DESIGN Scoping review. DATA SOURCES PubMed, PsycInfo, EMBASE, CINAHL, SportDiscus and Google Scholar electronic databases were searched using keywords related to IPPs and youth field sports. ELIGIBILITY CRITERIA FOR SELECTING STUDIES Studies of IPPs in youth field sports, that provided 'train-the-trainer' education to coaches as designated delivery agents. RESULTS 20 studies from two field sports (soccer/football; n=17, Rugby Union; n=3) fulfilled the eligibility criteria. Eleven CE interventions occurred in the preseason and 18 occurred at one time-point (single day). Five studies cited use of a behavioural change theory or model in the design of their CE, most frequently the Health Action Process Approach model (n=5); and use of behavioural change techniques varied. Twelve of twenty studies (60%) reported some form of ongoing support to coaches following the CE primary intervention concurrent with IPP implementation. CONCLUSION CE that occurs on 1 day (one time-point) is most popular for preparing coaches as delivery agents of IPPs in youth field sports. While recognising pragmatic barriers, more expansive in-service training, support and feedback may enhance the effective implementation of IPPs.

Abstract
Siyamthanda (Siya) Kolisi OIG (1992-) is the first black captain of the South African rugby team (Springboks) in its 128 years of existence. The Springboks have long been associated with Afrikaner people and a history of racism. Siya had to navigate a tumultuous upbringing in an environment characterised by various issues such as socioeconomic inequalities, high unemployment among Black people, and lack of resources. Siya was purposively selected for this study as he has become one of the most influential individuals in South Africa. Publicly available biographical data was gathered, analysed, and interpreted using the Phenomenological Variant of Ecological Systems Theory (PVEST; Spencer, 2006). I used the theoretical lens to understand the role of social and cultural context, meaning-making processes in human development, and the transition between different worlds. The findings indicated a need to consider the role of context as a source of consonance or dissonance in human development. The study also sheds light on the importance of viewing marginalised individuals holistically to facilitate smooth boundary transitions. Furthermore, it underscores the importance of recognising that maladaptive and adaptive coping strategies exist on a continuum. The study contributes towards non-WEIRD psychobiographical studies and understanding culture's role on human development.

Abstract
Objective Instrumented mouthguard (iMG) systems use different signal processing approaches limiting field-based inter-study comparisons, especially when artefacts are present in the signal. The objective of this study was to assess the frequency content and characteristics of head kinematic signals from head impact reconstruction laboratory and field-based environments to develop an artefact attenuation filtering method (HEADSport filter method). Methods Laboratory impacts (n=72) on a test-dummy headform ranging from 25 to 150 g were conducted and 126 rugby union players were equipped with iMGs for 209 player-matches. Power spectral density (PSD) characteristics of the laboratory impacts and on-field head acceleration events (HAEs) (n=5694) such as the 95th percentile cumulative sum PSD frequency were used to develop the HEADSport method. The HEADSport filter method was compared with two other common filtering approaches (Butterworth-200Hz and CFC180 filter) through signal-to-noise ratio (SNR) and mixed linear effects models for laboratory and on-field events, respectively. Results The HEADSport filter method produced marginally higher SNR than the Butterworth-200Hz and CFC180 filter and on-field peak linear acceleration (PLA) and peak angular acceleration (PAA) values within the magnitude range tested in the laboratory. Median PLA and PAA (and outlier values) were higher for the CFC180 filter than the Butterworth-200Hz and HEADSport filter method (p<0.01). Conclusion The HEADSport filter method could enable iMG field-based inter-study comparisons and is openly available at https://github.com/GTBiomech/HEADSport-Filter-Method.

Abstract
OBJECTIVES In rugby union (rugby), the tackle is the most frequent cause of concussion and thus a target for intervention to reduce concussion incidence. The aim of this study is to describe tackle characteristics and factors associated with illegal high tackles in amateur community-level rugby during a lowered (armpit level) tackle height law variation trial. DESIGN Prospective observational cohort study. METHODS Video surveillance of a single season, four-league competition with coding of video data according to a predefined coding framework. Descriptive statistics of tackle detail and logistic regression was performed to analyse factors associated with high tackles. RESULTS One hundred and eight matches with 14,679 tackles and a mean of 137 (±30) tackles per match were analysed. High tackles (above armpit level) had significantly greater odds of occurring in the lower (2nd-4th) leagues (OR: 1.95; 95 % CI: 1.6-2.4; p < 0.001), front-on tackles (OR: 1.61; 95 % CI: 1.3-2.0; p < 0.001), arm tackles (OR: 1.65; 95 % CI: 1.3-2.1; p < 0.001), bent-at-waist ball carrier (OR: 1.93; 95 % CI: 1.6-2.4; p < 0.001), falling/diving ball carrier (OR: 2.21; 95 % CI: 1.6-3.1; p < 0.001), and an upright tackler (OR: 3.38; 95 % CI: 2.7-4.2; p < 0.001). A falling/diving tackler had significantly lower odds of being associated with a high tackle (OR: 0.44; 95 % CI: 0.3-0.6; p < 0.001). CONCLUSIONS Overall mean tackles per match were similar to those of senior amateur and elite rugby. League, tackle type, tackle aspect, and player body positions were associated with high tackles. These findings reiterate the need for ongoing efforts to identify and implement mitigating strategies to reduce tackle-related injury risk.

Abstract
OBJECTIVES Tackle-related injuries account for up to 67% of all match injuries in women's rugby union. The perspective of women players on tackle injury can help key stakeholders understand psychosocial determinants of tackle injury risk and prevention. We aimed to capture psychosocial processes that explain tackle injury experiences and behaviours in women's rugby union. METHODS We conducted a qualitative study using a grounded theory approach. Adult women players, with at least 1-year senior level experience, were recruited from Europe, South Africa and Canada between December 2021 and March 2022. Data were collected through semistructured interviews and analysed in line with grounded theory coding procedures. RESULTS Twenty-one players, aged 20-48 years with a mean 10.6 years of rugby playing experience, participated. In our analysis, we identified three categories central to participants' experiences of tackle injury: (1) embodied understandings of tackle injury, (2) gender and tackle injury risk and (3) influences on tackle injury behaviours. Participants reported a sense of fear in their experience of tackling but felt that tackle injuries were an inevitable part of the game. Tackle injury was described based on performance limitations. Tackle injury risks and behaviours were influenced by gendered factors perpetuated by relations, practices and structures within the playing context of women's rugby union. CONCLUSION Women's tackle injury experiences were intertwined with the day-to-day realities of marginalisation and under preparedness. Grounded in the voices of women, we have provided recommendations for key stakeholders to support tackle injury prevention in women's rugby.

Abstract
OBJECTIVES Quantify and identify factors associated with concussion underreporting in Super League rugby league players. DESIGN Cross sectional survey. METHODS During the 2022 season preseason, 422 Men's and Women's Super League players completed an online survey quantifying player demographics, rugby playing history, concussion history, prevalence of, and reasons for underreporting concussion, concussion knowledge and long-term implications and perceptions of concussion. RESULTS Overall, 20% of respondents stated they did not report concussion-related symptoms to medical staff during the 2020 and 2021 seasons. The two most common reasons for underreporting concussion were 'didn't want to be ruled out of a match' (35%) and 'didn't want to let down team' (24%). 65% of players reported an appropriate level of knowledge about concussion and potential long-term implications at the start of their senior rugby career, versus 89% now. In relation to concussion knowledge, symptoms were correctly identified on 74% of occasions. 57% of players surveyed were concerned about the potential long-term implications from concussion, and 11% of players would encourage their/family members' children to not play rugby league. CONCLUSIONS The proportion of Super League players who did not report concussion symptoms was similar to rugby league players in Australia. The main reasons for not reporting concussion appeared to be due to perceptions of what is beneficial for the team, suggesting both performance and medical staff should collectively encourage players to report concussion. A player's attitude towards concussion is potentially an individual modifiable risk factor and should be considered within the concussion management of players.

Abstract
There is a growing concern around concussions in rugby union, at all levels of the game. These concerns highlight the need to better manage and care for players. However, consistency around concussion-related responsibilities of stakeholders across the community rugby system remains challenging. Taking a systems thinking approach, this pragmatic, qualitative descriptive study explored key stakeholder groups within New Zealand's community rugby system's perceptions of their own and others' concussion-related responsibilities. Participants included players from schools and clubs, coaches, parents, team leads and representatives from four provincial unions. A total of 155 participants (67 females and 88 males) were included in the study. Focus groups and individual interviews were conducted. Thematic content analysis was used to analyse data. Thirty concussion-related responsibilities were identified. These responsibilities were contained within four themes: (1) policies and support (responsibilities which influence policy, infrastructure, human or financial resources); (2) rugby culture and general management (responsibilities impacting players' welfare and safety, attitudes and behaviour, including education, injury reporting and communication); (3) individual capabilities (responsibilities demonstrating knowledge and confidence managing concussion, leadership or role/task shifting) and (4) intervention following a suspected concussion (immediate responsibilities as a consequence of a suspected concussion). The need for role clarity was a prominent finding across themes. Additionally, injury management initiatives should prioritise communication between stakeholders and consider task-shifting opportunities for stakeholders with multiple responsibilities. How concussions will realistically be managed in a real-world sports setting and by whom needs to be clearly defined and accepted by each stakeholder group. A 'framework of responsibilities' may act as a starting point for discussion within different individual community rugby contexts on how these responsibilities translate to their context and how these responsibilities can be approached and assigned among available stakeholders.

Abstract
OBJECTIVE This study aimed to identify the risk factors for tackle-related concussion observed in matches involving under (U) 18, U 22 and professional men's Rugby Union players through video analysis. STUDY DESIGN Descriptive epidemiology study. METHODS Twenty Rugby Union matches each for high school (U18), university/college (U22) and professional (Elite) were randomly selected from 202 matches in the 2018/2019 season. Both one-on-one and tackles involving multiple tacklers were analyzed for the 60 matches. The 28 categorical and continuous variables (e.g., tackle characteristics and duration before the tackle) were applied as risk factors to a least absolute shrinkage and selection operator (Lasso) regression analysis. To identify high-risk situations, a simulation model with coefficients obtained from the Lasso regression was used. Statistical analysis was conducted according to tackle direction. RESULTS A total of 14,809 tackles and 41 concussions involving 1800 players were included in the analyses. The incidence rate of concussions (injuries/1000 tackles) was greater in Elite players (4.0) compared with U18 (1.9) and U22 (2.4) players. The factors most highly associated with concussions were head-in-front tackles (where the tackler's head is placed forward, impeding a ball carrier's forward movements, 11.26/1000 tackles), and were more often observed among U18 players. A simulation model predicted that the highest risk tackle situation in Elite players was a head-in-front, side-on tackle below the hip of the ball carrier (predicted incidence rate 18.07/1000 tackles). CONCLUSION The risk factors associated with concussion need to be assessed cautiously. Avoiding head-in-front, side-on tackles to the lower extremities of a ball carrier should be considered to reduce injury risks.

Abstract
Video analysis is a useful tool for injury surveillance in rugby union. There are few video analysis studies in the professional female game, with most studies published in the male elite/professional settings. Moreover, there is a sparsity of literature in youth rugby settings. The following narrative review outlines the strengths and limitations of the current video analysis literature for injury surveillance in youth rugby union, highlights the importance of video analysis for youth rugby player safety and welfare, and discusses recommendations for using video analysis to inform player safety in youth rugby.

Abstract
The aim of this scoping review was to present an overview of the existing epidemiological evidence in retired male and female elite rugby players regarding the prevalence rates of musculoskeletal, cardiovascular, neurocognitive, psychological and gynaecological health conditions. A systematic search was carried out across MEDLINE (via PubMed), SPORTDiscus (via EBSCOhost), PsycINFO (via EBSCOhost) and EMBASE for musculoskeletal (eg, osteoarthritis), cardiovascular (eg, hypertension), neurocognitive (eg, dementia) and psychological health (eg, disordered eating, alcohol misuse) conditions in retired elite male and female rugby players and gynaecological health conditions (menorrhagia) in retired female rugby players. Primary research studies describing the prevalence rates of health conditions in retired elite male and female rugby players written in English, Dutch or French and with full text available online were included. Five hundred and seventy-three citations were originally identified and 16 studies were ultimately included in our review. No studies on health conditions in retired elite female rugby players were found. Four individual studies showed there was a significant higher prevalence rate of osteoarthritis in retired elite male rugby players compared with control groups. Various neurocognitive health conditions were investigated and showed, among others, a prevalence rate of 57% for mild cognitive disorder. The prevalence of self-reported depression and hazardous alcohol use in retired elite male rugby players was significantly higher than in control groups matched for age and education. Our review found relatively high prevalence rates of musculoskeletal health conditions such as osteoarthritis and psychological health conditions such as depression and hazardous alcohol use in retired elite male rugby players. More research needs to be conducted to understand better the health conditions of retired elite rugby players, especially among retired elite female players.

Abstract
OBJECTIVES The purpose of this study was to investigate the relationship between on-field post-concussion symptoms reported by athletes, on-field neurological signs reported by a trainer or physician, and/or post-concussion symptoms 72 h after brain injury in male rugby players. DESIGN Cross-sectional study in a Sports Concussion Clinic setting. METHODS We enrolled 92 adult rugby union players, within the first 72 h after sport concussion. Four scales were measured. Immediate Concussion Sign Checklist (sideline); Immediate Concussion Symptom Checklist (24 h after concussion); Post-Concussion Symptoms Scale and Beck Depression Inventory (in-office 72 h after concussion). RESULTS Odds ratios revealed that overtly symptomatic athletes were over 2.6 times more likely (p = 0.047) to exhibit post-traumatic amnesia than asymptomatic athletes. There were no differences in terms of on-field loss of consciousness or confusion. Immediate symptoms reported by athletes retrospectively were associated with symptoms reported on the Beck Depression Inventory (odds ratio 2.8; 95 % confidence interval 1.14-6.88), headache (odds ratio 4.9; 95 % confidence interval 1.92-12.79), memory concerns (odds ratio 3.15; 95 % confidence interval 1.06-9.34), pressure in the head (odds ratio 2.8; 95 % confidence interval 1.03-8.08), and visual disturbances (odds ratio 3.9; 95 % confidence interval 1.05-14.50) reported 72 h after sports concussion. CONCLUSIONS Athletes who were overtly symptomatic after sports concussion were significantly more likely to experience post-traumatic amnesia and two or more on-field concussion signs relative to those athletes who were asymptomatic. Also, players with immediate symptoms reported higher depressive symptoms, somatic symptoms (headache and visual disturbances), and cognitive symptoms.

Abstract
BACKGROUND To determine the effect of contact/collision sport participation on measures of single-task (ST) and dual-task (DT) gait among early- to middle-aged adults. METHODS The study recruited 113 adults (34.88 ± 11.80 years, (mean ± SD); 53.0% female) representing 4 groups. Groups included (a) former non-contact/collision athletes and non-athletes who are not physically active (n = 28); (b) former non-contact/collision athletes who are physically active (n = 29); (c) former contact/collision sport athletes who participated in high-risk sports and are physically active (n = 29); and (d) former rugby players with prolonged repetitive head impact exposure history who are physically active (n = 27). Gait parameters were collected using inertial measurement units during ST and DT gait. DT cost was calculated for all gait parameters (double support, gait speed, and stride length). Groups were compared first using one-way analysis of covariance. Then a multiple regression was performed for participants in the high-risk sport athletes and repetitive head impact exposure athletes groups only to predict gait outcomes from contact/collision sport career duration. RESULTS There were no significant differences between groups on any ST, DT, or DT cost outcomes (p > 0.05). Contact/collision sport duration did not predict any ST, DT, or DT cost gait outcomes. CONCLUSION Years and history of contact/collision sport participation does not appear to negatively affect or predict neurobehavioral function in early- to mid-adulthood among physically active individuals.

Abstract
Day-to-day coordination of the stress (i.e., hypothalamic-pituitary-adrenal [HPA]) and reproductive (i.e., hypothalamic-pituitary-gonadal [HPG]) axes is central to allostatic regulation, reproductive success, and survival. Reports of positive, within-person testosterone and cortisol relationships (or coupling) suggest cross-talk of a facilitative nature, but longitudinal evidence is scarce and has methodological and analytical limitations. To address this, we used a continuous-time (CT) model to investigate day-to-day, within-person coupling of testosterone and cortisol in two male cohorts. Salivary testosterone and cortisol fluctuations were monitored in 35 athletic men across two international tournaments (M = 19.3 tests) and in 41 healthy men during normal daily living (M = 27.9 tests). Bayesian CT analysis revealed a diminishing effect of each hormone on itself as time-interval length or lag increased. In both groups, cortisol had a negative lagged effect on testosterone that persisted for around three days. The cortisol effect on testosterone peaked after 0.71 and 0.51 days in athletic (standardized estimate = -0.13) and healthy men (standardized estimate = -0.11), respectively. Further estimates of non-lagged, contemporaneous correlations revealed positive testosterone and cortisol relationships (athlete r = 0.04, healthy r = 0.46). In summary, complex within-person HPA and HPG interplay emerged in two independent male cohorts. Specifically, a rising cortisol concentration was linked to a fall in testosterone concentration at later time points, but concurrently these hormones tended to rise and fall together. Our results suggest that inhibitory and facilitatory hormonal actions coexist on varying timescales, thereby expanding knowledge of HPG and HPA cross-talk in everyday life.

Abstract
OBJECTIVE Develop a questionnaire to monitor symptoms of player perceived shoulder function/dysfunction. DESIGN 3-Stage Online Delphi Study. METHODS Participants: surgeons, sports and exercise medics, academic researchers, strength and conditioning coaches, therapists and athletes split by level of expertise/experience. Stage-1: experts (n = 12) rated constructs/items from the steering group and made changes/proposed additional constructs/items. Stage-2: experts rated/amended new constructs/items from stage-1. Stage-3: experienced professionals (n = 25) rated/ranked constructs/items from stage 2. Consensus thresholds were defined per stage (≥50% agreement/4-5 rating on 1-5 Likert scale (stages 1-2), ≥68% agreement, and items ranked for perceived importance (stage-3)). RESULTS Stage-1, all four constructs (a. Activities of daily living, b. Range of motion, c. Strength and conditioning, d. Sports specific training and competition) and 26/42 original items achieved consensus. Twelve items were combined into five items. Four new items were also proposed. Stage-2, the combined items and three of the four new items achieved consensus. Stage-3 the four constructs and 22 items all achieved consensus. CONCLUSIONS Following a 3-stage online Delphi process, involving expert and experienced clinicians, practitioners and athletes, a new four construct, 22 item RSF questionnaire has been developed which can be used with rugby players, to monitor perceived shoulder performance and symptoms.

Abstract
Study Design The investigators designed and implemented a 20-year cross-sectional study using the National Electronic Injury Surveillance System database. Objective The purpose of this study is to estimate and compare hospital admission (danger) rates between rugby and football of those who presented to the emergency department with head and neck injuries after playing these sports. Methods The primary predictor variable was sport played. The primary outcome variable was danger, measured by hospital admission rates. Results Over the past 20 years, there has been a trend of decreasing incidence of injuries presenting to the emergency department in both sports. There was no difference in the rate of hospital admission when comparing football and rugby (OR, 1.2; P = .1). Male gender was associated with an increased risk of admission. Other variables associated with hospital admission included white racial group, injury taking place in the fall, being either young (15-24 years old) or senior (65 years of age and over), and being injured at school or at a sport/recreational facility. Conclusions There is no difference in danger as measured by admission rates between American football and rugby. There exists, however, several variables that are associated with admission when sustaining injury to the head and neck, when playing these two sports.

Abstract
Purpose: Although physical and technical performance are both fundamental in rugby union teams, the association between these variables in sub-elite players is limited. This study investigated the association between the rate of success and unsuccess in technical skills throughout a season with physical quality variables in sub-elite rugby players. Methods: Twenty-five sub-elite rugby union players (age: 26.4 ± 3.8 years; body mass: 99.68 ± 14.34 kg; height: 1.81 ± 0.07 m) completed the following assessments: (i) broad jump; (ii) 10- and 30-meters sprint speed; (iii) 5-10-5 test; (iv) 1 RM of bench press, chin-up and squat and (v) Yo-Yo fitness test. The rate of success and unsuccess in tackles, attacking rucks and carries were measured during a season. Results: We found that: (i) higher success rates in carries were associated with faster speeds and greater broad jump distance; (ii) higher unsuccess rates in tackles were associated with lower 1 RM chin-up. When controlling for playing position, (iii) higher success rates in carries were associated with 30-meters speed and broad jump distance; (iv) higher success rates in tackles were associated with higher 1 RM chin-up; and (v) higher unsuccess rates in tackles were associated with lower 1 RM chin-up. Conclusions: Success and unsuccess rates in attacking rucks and success in carries were not associated with physical qualities. Therefore, training programs that improve speed, lower limb power and upper limb maximal strength should receive greater attention when seeking to achieve greater success in trying to break the opponent's defensive line and stop the ball carrier.

Abstract
ObjectiveTo establish match injury rates and patterns in elite female rugby union players in England. METHOD We conducted a six-season (2011/2012-2013/2014 and 2017/2018-2019/2020) prospective cohort study of time-loss match injuries in elite-level female players in the English Premiership competition. A 24-hour time-loss definition was used. RESULTS Five-hundred and thirty-four time-loss injuries were recorded during 13 680 hours of match exposure. Injury incidence was 39 injuries per 1000 hours (95% CIs 36 to 42) with a mean severity of 48 days (95% CIs 42 to 54) and median severity of 20 days (IQR: 7-57). Concussion was the most common specific injury diagnosis (five concussions per 1000 hours, 95% CIs 4 to 6). The tackle event was associated with the greatest burden of injury (615 days absence per 1000 hours 95% CIs 340 to 1112), with 'being tackled' specifically causing the most injuries (28% of all injuries) and concussions (22% of all concussions). CONCLUSIONS This is the first multiple-season study of match injuries in elite women's rugby union players. Match injury incidence was similar to that previously reported within international women's rugby union. Injury prevention strategies centred on the tackle would focus on high-burden injuries, which are associated with substantial player time-loss and financial costs to teams as well as the high-priority area of concussions.

Abstract
Rugby league has a relatively high injury risk, with the tackle having the greatest injury propensity. The number of tackles players engage in, prior to injurious tackles may influence injury risk, which has yet to be investigated. Therefore, this study investigated if rugby league players are involved in more tackles (as either tackler or ball carrier) (i) in the 10 minutes, or (ii) 1-min periods prior to an injurious tackle-event, (iii) differences for ball carriers vs. tacklers, and (iv) forwards vs. backs. Video analysis was utilised to quantify the number and rate of tackles in the 10-min periods prior to 61 tackle-related injuries. One thousand two hundred and eighty 10-min periods where players were not injured, were used as matched-controls. Generalized mixed linear models were used to analyse mean total and rate for tackles. Injured players were involved in significantly fewer tackles during the 10-min period, yet significantly more tackles during the final minute prior to the injurious tackle-event, compared to non-injured players. There were no differences between ball carriers vs. tacklers during the 10-min period. Both injured position groups were involved in significantly more tackles in the final minute. Additional match data sources are needed to further inform injury preventive strategies of tackle events.

Abstract
Illness prevention is essential for athlete health management, but little is known about its uptake in sport. Prior to the pandemic, the International Olympic Committee (IOC) published a consensus statement recommending illness prevention guidelines are implemented in sports. Yet, little is known about guideline uptake. Therefore, this study aimed to explore the (1) illness experiences of rugby players and athlete support personnel and (2) barriers and enablers to illness prevention guideline uptake in rugby, using the lens of behaviour change theory. In a bid to inform and enhance athlete welfare, we sought to amplify the voices of participants through qualitative inquiry. Between August 2020 and May 2021, 16 semi-structured interviews were undertaken with players and athlete support personnel working across rugby. Analysis was conducted using Braun and Clarke's reflexive thematic analysis. Prior to COVID-19, participants deemed illness to be of little concern, with experience of illnesses and the global pandemic critical enablers to guideline uptake. The rugby environment was a barrier to illness prevention, particularly in women's and academy teams where resource deficiency was highlighted. 'Rugby identity' acted as both a barrier and enabler with participants' passion for rugby driving both guideline adherence and non-adherence. Tackling resource inequalities between men's and women's cohorts is critical to effectively implement guidelines. Coach and player education is essential, and emphasis must be placed on continuing preventative behaviours adopted due to COVID-19. Our findings offer new insight into illness prevention, moving away from prevailing quantitative research, and instead voicing players' experiences.

Abstract
OBJECTIVES To investigate the influence of previous season match exposure on injury incidence and burden in elite men's rugby union. DESIGN A three-season (2016-17 to 2018-19) retrospective cohort design was used to collect and analyse injury and exposure data across English Premiership rugby union teams. METHODS Generalised linear mixed-effects models were used to model the influence of match exposure (all match involvements, match involvements of ≥20 mins, and full-game equivalents) upon match and training injury incidence and burden in the following season. RESULTS Involvement in ≥31 matches within a season was associated with substantially increased match and training injury burden in the following season. Match exposure was not clearly associated with injury incidence in the following season. The increased match injury burden associated with higher match involvements appeared to be driven by an increased risk for older (>26 y) Forwards, whilst the increased training injury burden associated with higher match involvements appeared to be driven by an increased risk for older (>26 y) Backs. CONCLUSIONS The present study demonstrates that all match involvements, regardless of duration, should be considered when exploring associations between match exposure and injury risk. High match involvements (≥ 31 matches) are associated with elevated injury burden, in both matches and training, in the following season. The physical and psychological load of players with high previous-season match exposure should be carefully managed.

Abstract
We explored male professional rugby union players' experiences and perceptions of their mental and physical health and well-being across the northern hemisphere off-season. 34 professional male rugby union players participated in individual semistructured interviews (mean (SD) age=27.5 (4.3) years). Interviews were recorded, transcribed verbatim and analysed using reflexive thematic analysis. The off-season was characterised by three phases players undergo to preserve their mental and physical health and well-being to recover from the previous season and regenerate in preparation for the upcoming season. These included decompression from previous season, cognitive detachment from the rugby environment and preparation for preseason. Successful progression through all three phases was influenced by several variables (work and life demands, contextual factors, experience level). Recovery and regeneration strategies focused on physical distancing/getting away from the rugby environment to cognitively detach. Injured players appear an at-risk subgroup for threats to mental well-being (isolation, anxiety, reduced sense of achievement) as a result of reduced or minimal time away from the workplace due to treatment obligations. Younger professionals are a subgroup at risk of overtraining/injury due to inadequate rest, especially as this group are least likely to seek support/guidance. This study is the first investigation into male professional rugby union players' experiences and perceptions of their mental and physical health and well-being across the off-season period. It highlights the distinct phases players undertake to mentally recover and regenerate and the need to consider education and support for potential at risk subgroups.

Abstract
OBJECTIVES To analyse match and training injury incidence rates and burden from pre-(2019) and post-COVID-19 (2021) seasons; To analyse injury related variables as mechanisms, type, body locations, severity and the differences of the most common injuries according to playing positions. DESIGN An observational study was performed according to the consensus statement on injury definitions and data collection from World Rugby. Injury variables were collected retrospectively for 2019 season and prospectively during 2021 season. SETTING Argentinian amateur rugby club. PARTICIPANTS Male (n = 110) senior amateur rugby players. MAIN OUTCOME MEASURES Match and training time loss injuries, time of exposures and injury related variables. RESULTS Training incidence rate during post-lockdown season (4.2/1000 player-training-hours) was significantly higher (p < 0.001) than the pre-lockdown season (0.9/1000 player match hours). Post-lockdown hamstring strain injury (HSI) and concussions match incidence rates were significantly (p < 0.001; p < 0.05 respectively) higher in comparison with 2019 season. Regarding playing positions, backs showed a significantly increase (p < 0.05) in HSI match incidence rate post lockdown. CONCLUSIONS After the COVID-19 lockdown, training incidence rate was significantly higher than previous season (2019), showing the impact of the lockdown restrictions. Coaches and medical staff must consider that players probably need more lead-in time for conditioning and more monitoring after periods of no rugby.

Abstract
Background Cerebrovascular injuries (CVIs) are not usually considered in the differential diagnosis of sport-related head injuries (SRHIs). We encountered a rugby player with traumatic dissection of the anterior cerebral artery (ACA) after impact on the forehead. Head magnetic resonance imaging (MRI) with T1-volume isotropic turbo spin-echo acquisition (VISTA) was used to diagnose the patient. Case Description The patient was a 21-year-old man. During a rugby tackle, his forehead collided with the forehead of an opponent. He did not have a headache or disturbance of consciousness immediately after the SRHI. On the 2nd day of illness, he had transient weakness of the left lower limb several times. On the 3rd day of illness, he visited our hospital. MRI revealed occlusion of the right ACA and acute infarction of the right medial frontal lobe. T1-VISTA revealed intramural hematoma of the occluded artery. He was diagnosed with acute cerebral infarction due to dissection of the ACA and was followed up for vascular changes with T1-VISTA. The vessel had recanalized and the size of the intramural hematoma had decreased 1 and 3 months after the SRHI, respectively. Conclusion Accurate detection of morphological changes in cerebral arteries is important for the diagnosis of intracranial vascular injuries. When paralysis or sensory deficits occur after SRHIs, it is difficult to differentiate between concussion from CVI. Athletes with red-flag symptoms after SRHIs should not merely be suspected to have concussion; they should be considered for imaging studies.

Abstract
STUDY DESIGN AND SETTING Returning rugby players to the sport following musculoskeletal injuries is a multi-factorial and challenging process. A cross-sectional observational study was conducted among health and sport practitioners involved with injured rugby players in South Africa. OBJECTIVES AND OUTCOME MEASURES The views, current practices and barriers encountered by health and sport practitioners during return to rugby were investigated using a self-developed online survey. RESULTS 64 practitioners participated in the survey including physiotherapists, orthopaedic surgeons, biokineticists and sports physicians. Return to sport (RTS) protocols were considered important, however, participants also indicated that they were slightly more likely to use anecdotal protocols compared to published protocols. Time frames, stages of healing, pain and subjective ratings along with functional outcome measures (such as range of motion, muscle function and proprioception) and sport-specific skills were rated as important and commonly utilised in different RTS phases (i.e., return to non-contact, return to contact and return to matches). The most commonly perceived barriers encountered were related to lack of access and time-constraints. CONCLUSION Return to rugby guidelines with consideration of a broad range of criteria and common barriers encountered should be developed to facilitate safe, practical and time-efficient return to rugby following musculoskeletal injuries.

Abstract
Results in contact sports like Rugby are mainly interpreted in terms of the ability and/or luck of teams. But this neglects the important role of the motivation of players, reflected in the effort exerted in the game. Here we present a Bayesian hierarchical model to infer the main features that explain score differences in rugby matches of the English Premiership Rugby 2020/2021 season. The main result is that, indeed, effort (seen as a ratio between the number of tries and the scoring kick attempts) is highly relevant to explain outcomes in those matches.

Abstract
OBJECTIVES Rugby is a high-impact collision sport with identical competition rules by sex. The aim of this study was to analyze the trend of rugby-related fractures by body site, sex, and age in amateur athletes from 1999 to 2018. METHODS The National Electronic Injury Surveillance System (NEISS) database was queried to characterize rugby-related injuries from 1999 to 2018 in patients aged 14-23 years old. National injury estimates were calculated using sample weights. Chi-square analysis and one-way ANOVA were performed to compare categorical variables. RESULTS Out of a total of 43,722 weighted cases of rugby-related fractures over the 19-year period, 70.9% were among high school- and college-aged males and females between the ages of 14-23 years (N = 30,996). Males constituted 79.3% of cases whereas females composed 20.7% of the cases. The proportion of upper extremity fractures was similar in both males and females, yet facial fractures were significantly more common among males than females (27.9% vs. 14.6%, P < 0.001). Among facial fractures, nasal fractures represented 74.4% of the sample, yet facial fractures only resulted in hospital admittance in 1.3% of cases. Lower extremity fractures were more likely to be severe, with 11.3% of LE cases being admitted to the hospital. CONCLUSION Rugby players in the US diagnosed in the ED with fractures consisted largely of male, high school- and college-aged athletes. Males and females experienced upper and lower-extremity fractures at comparable rates, yet lower extremity injuries were more likely to be admitted to a hospital. Men were significantly more likely to experience a facial fracture in which a majority were nasal fractures.

Abstract
The importance of contributors that can result in negative player outcomes in sport and the feasibility and barriers to modifying these to optimise player health and well-being have yet to be established. Within rugby codes (rugby league, rugby union and rugby sevens), within male and female cohorts across playing levels (full-time senior, part-time senior, age grade), this project aims to develop a consensus on contributors to negative biopsychosocial outcomes in rugby players (known as the CoNBO study) and establish stakeholder perceived importance of the identified contributors and barriers to their management. This project will consist of three parts; part 1: a systematic review, part 2: a three-round expert Delphi study and part 3: stakeholder rating of feasibility and barriers to management. Within part 1, systematic searches of electronic databases (PubMed, Scopus, MEDLINE, SPORTDiscus, CINAHL) will be performed. The systematic review protocol is registered with PROSPERO. Studies will be searched to identify physical, psychological and/or social factors resulting in negative player outcomes in rugby. Part 2 will consist of a three-round expert Delphi consensus study to establish additional physical, psychological and/or social factors that result in negative player outcomes in rugby and their importance. In part 3, stakeholders (eg, coaches, chief executive officers and players) will provide perceptions of the feasibility and barriers to modifying the identified factors within their setting. On completion, several manuscripts will be submitted for publication in peer-reviewed journals. The findings of this project have worldwide relevance for stakeholders in the rugby codes. PROSPERO registration number CRD42022346751.

Abstract
New Zealand Rugby (NZR) implemented a concussion management pathway (CMP), aimed at improving management at community level. General Practitioners (GPs) played a large role in the design of this process. The objective of this study was to explore GPs' perceptions of barriers and facilitators of the CMP and rugby-related concussion management in the community. A descriptive qualitative approach using interviews and focus groups was employed. Four themes were derived: i) GPs' existing knowledge and confidence around concussion management; ii) Operational resources: time, remuneration and pathway guidance; iii) Standardising concussion care and iv) Expanding the circle of care - the need for multi-disciplinary healthcare team. These themes described how GP's concussion knowledge, and the efficiency and availability of operational resources affected their experience and ability to fulfil their tasks within the CMP. GPs found NZR's CMP especially valuable, as it provided guidance and structure. Expanding the role of other healthcare providers was seen as critical to reduce the burden on GPs, while also delivering a more holistic experience to improve clinical outcomes. Addressing the identified barriers and expanding the network of care will help to improve the ongoing development of NZR's CMP, while supporting continued engagement with all stakeholders.

Abstract
Purpose To assess indirect markers of intestinal endothelial cell damage and permeability in academy rugby players in response to rugby training at the beginning and end of preseason. Methods Blood and urinary measures (intestinal fatty acid binding protein and lactulose:rhamnose) as measures of gastrointestinal cell damage and permeability were taken at rest and after a standardised collision-based rugby training session in 19 elite male academy rugby players (age: 20 ± 1 years, backs: 89.3 ± 8.4 kg; forwards: 111.8 ± 7.6 kg) at the start of preseason. A subsample (n = 5) repeated the protocol after six weeks of preseason training. Gastrointestinal symptoms (GIS; range of thirteen standard symptoms), aerobic capacity (30–15 intermittent fitness test), and strength (1 repetition maximum) were also measured. Results Following the rugby training session at the start of preseason, there was an increase (median; interquartile range) in intestinal fatty acid binding protein (2140; 1260–2730 to 3245; 1985–5143 pg/ml, p = 0.003) and lactulose:rhamnose (0.31; 0.26–0.34 to 0.97; 0.82–1.07, p < 0.001). After six weeks of preseason training players physical qualities improved, and the same trends in blood and urinary measures were observed within the subsample. Overall, the frequency and severity of GIS were low and not correlated to markers of endothelial damage. Conclusions Rugby training resulted in increased intestinal endothelial cell damage and permeability compared to rest. A similar magnitude of effect was observed after six weeks of pre-season training. This was not related to the experience of GIS.

Abstract
In collision sports, the tackle has the highest injury incidence, and is key to a successful performance. Although the contact load of players has been measured using microtechnology, this has not been related to tackle technique. The aim of this study was to explore how PlayerLoad™ changes between different levels of tackling technique during a simulated tackle. Nineteen rugby union players performed twelve tackles on a tackle contact simulator (n = 228 tackles). Each tackle was recorded with a video-camera and each player wore a Catapult OptimEyeS5. Tackles were analysed using tackler proficiency criteria and split into three categories: Low scoring(≤5 Arbitrary units (AU), medium scoring(6 and 7AU) and high scoring tackles(≥8AU). High scoring tackles recorded a higher PlayerLoad™ at tackle completion. The PlayerLoad™ trace was also less variable in the high scoring tackles. The variability in the PlayerLoad™ trace may be a consequence of players not shortening their steps before contact. This reduced their ability to control their movement during the contact and post-contact phase of the tackle and increased the variability. Using the PlayerLoad™ trace in conjunction with subjective technique assessments offers coaches and practitioners insight into the physical-technical relationship of each tackle to optimise tackle skill training and match preparation.

Abstract
Successful athletes are better at performing efficiently than the inferior in particular sports scenarios, while most existing performance tests in the field do not cover the sport-specific context fully. There were two purposes in this study: 1) to evaluate the reliability and validity of a novel Sector Reactive Agility Test (SRAT) which mimicked a reactive-agility defensive scenario in Touch, and 2) to determine the relationships between Touch players' agility and sprint performance. Twenty male Touch players from the elite division and another 20 from the amateur division were invited to participate in this study. They performed SRAT and a 20-m sprint test in two days. Excellent reliability and high precision were found in SRAT (intraclass correlation coefficient [ICC] = 0.97) and 20-m sprint test (ICC = 0.91). The time of completion in SRAT of the elite Touch players (23.93 s) was 2.95 s significantly shorter than that of the amateur players with a large effect size. Elite Touch players also demonstrated moderately faster (0.11 s) than the amateur Touch players in the 20-m sprint test. SRAT demonstrated high test-retest reliability and accuracy in measuring reactive-agility performance in Touch. The minimal detectable changes in SRAT and 20-m sprint test were 1.04 s and 0.13 s respectively. Furthermore, the speed of the 20-m sprint test and playing experience were associated with the time of completion of SRAT, explaining 56% of its variance (p < 0.001). Other factors, such as cognition and the ability to control own central gravity, are deemed possible to influence Touch players' agility. Therefore, SRAT should be adopted in Touch player selection and training monitoring.

Abstract
World Rugby employs a specific drop test method to evaluate headgear performance, but almost all researchers use a different variation of this method. The aim of this study was, therefore, to quantify the differences between variations of the drop testing method using a Hybrid III headform and neck in the following impact setups: (1) headform only, with a flat steel impact surface, approximating the World Rugby method, (2 and 3) headform with and without a neck, respectively, onto a flat MEP pad impact surface, and (4) headform and neck, dropped onto an angled MEP pad impact surface. Each variation was subject to drop heights of 75-600 mm across three orientations (forehead, side, and rear boss). Comparisons were limited to the linear and rotational acceleration and rotational velocity for simplicity. Substantial differences in kinematic profile shape manifested between all drop test variations. Peak accelerations varied highly between variations, but the peak rotational velocities did not. Drop test variation also significantly changed the ratios of the peak kinematics to each other. This information can be compared to kinematic data from field head impacts and could inform more realistic impact testing methods for assessing headgear.

Abstract
OBJECTIVES The objective of this study was to identify and report the incidence and mechanisms of suspected injury and concussion in women's rugby union. DESIGN A cross-sectional video analysis study. METHODS Using video analysis of non-professional, single-angle footage, cases of suspected injury and concussion were identified and reported, based on content validation and consensus by eight rugby-specific researchers, therapists, and sport medicine physicians. RESULTS There were 225 suspected injuries recorded in 48 games [Suspected injury rate (IR) = 117.5/1000 h (95 % CI;102.6-133.9) or 4.7 suspected injuries per match]. The on-field medical attention IR was 95.0/1000 h (95 % CI;81.7-109.9: 3.8 per game). Suspected concussions accounted for 26 % of injuries (30.8/1000 h: 95 % CI;23.5-39.7: 1.2 per game). The attacking team sustained 64 % of suspected injuries. Permanent removal from play was observed for 29 % of suspected injuries. The most common suspected injury locations were head/neck (28.4 %) and lower extremity (27.6 %). The tackle accounted for 67.1 % of all suspected injuries, with a propensity of 11.2/1000 tackle events (95 % CI;9.5-13.2) or 3.1 tackle-related injuries/game. Of tackle-related injuries, 63.6 % were to the ball carrier while 52.2 % of tackle-related concussions were to the ball carrier. CONCLUSION This study adds to the growing body of literature examining women's rugby. The rate of suspected injury is high compared with other studies. It is acknowledged that these are suspected injuries not supported by prospective injury surveillance. The high proportion of suspected injuries that are tackle-related warrants specific attention to identify tackle characteristics associated with injury and concussion.

Abstract
OBJECTIVE The efficacious Activate injury prevention exercise programme has been shown to prevent injuries in English schoolboy rugby union. There is now a need to assess the implementation and effectiveness of Activate in the applie setting. METHODS This quasi-experimental study used a 24-hour time-loss injury definition to calculate incidence (/1000 hours) and burden (days lost/1000 hours) for individuals whose teams adopted Activate (used Activate during season) versus non-adopters. The dose-response relationship of varying levels of Activate adherence (median Activate sessions per week) was also assessed. Player-level rugby exposure, sessional Activate adoption and injury reports were recorded by school gatekeepers. Rate ratios (RR), adjusted by cluster (team), were calculated using backwards stepwise Poisson regression to compare rates between adoption and adherence groups. RESULTS Individuals in teams adopting Activate had a 23% lower match injury incidence (RR 0.77, 95% CI 0.55 to 1.07), 59% lower training injury incidence (RR 0.41, 95% CI 0.17 to 0.97) and 26% lower match injury burden (95% CI 0.46 to 1.20) than individuals on non-adopting teams. Individuals with high Activate adherence (≥3 sessions per week) had a 67% lower training injury incidence (RR 0.33, 95% CI 0.12 to 0.91) and a 32% lower match injury incidence (RR 0.68, 95% CI 0.50 to 0.92) than individuals with low adherence (<1 session per week). While 65% of teams adopted Activate during the season, only one team used Activate three times per week, using whole phases and programme progressions. CONCLUSION Activate is effective at preventing injury in English schoolboy rugby. Attention should focus on factors influencing programme uptake and implementation, ensuring Activate can have maximal benefit.

Abstract
INTRODUCTION The sequelae of concussion are of growing concern within Rugby. World Rugby has introduced rule changes to improve player welfare and reduce head injury frequency. We aimed to report the incidence of head injuries and head injury assessment (HIA) at the 2019 Rugby World Cup (RWC). METHODS We reviewed all 45 tournament matches and recorded the number of head injuries, the injured player's position, and the mechanism of injury; whether the player had an HIA; and if they returned to play following injury. We compared these findings with previous RWCs. RESULTS We recorded 68 head injuries (1.33/game). Thirty-six players (52.9%) were removed from the field of play for an HIA. Of these, 23 (63.9%) failed and therefore considered to have concussion. The head injury rate in 2019 was 37.8 per 1000 player hours, which increased from previous tournaments (22.0 in 2015, 14.6 in 2011, and 4.7 in 2007). The concussion rate was 23 per 1000 player hours in 2019, which was lower than 29 in 2015. In 2019, 63.9% of HIAs were failed compared to 48.7% in 2015. We identified 17 cases where medical staff did not attend to a player suffering a head injury on-field. Of these, four players underwent an HIA after the match doctor reviewed the incident. CONCLUSION We recorded a higher rate of head injuries, and a player was more likely to fail their HIA than in previous tournaments. These findings may represent a greater awareness from medical staff and the benefits of education. However, 25% of head injuries not receiving an initial on-field assessment provide room for improvement.

Abstract
OBJECTIVE Challenges remain in sports-related concussion (SRC) assessment to better inform return to play. Reliance on self-reported symptoms within the Sports Concussion Assessment Tool means that there are limited data on the effectiveness of novel methods to assess a player's readiness to return to play. Digital methods such as wearable technologies may augment traditional SRC assessment and improve objectivity in making decisions regarding return to play. METHODS The participant was a male university athlete who had a recent history of SRC. The single-participant design consisted of baseline laboratory testing immediately after SRC, free-living monitoring, and follow-up supervised testing after 2 months. The primary outcome measures were from traditional assessment (eg, Sports Concussion Assessment Tool and 2-minute instrumented walk/gait test; secondary outcome measures were from remote (free-living) assessment with a single wearable inertial measurement unit (eg, for gait and sleep). RESULTS The university athlete (age = 20 years, height = 175 cm, weight = 77 kg [176.37 lb]) recovered and returned to play 20 days after SRC. Primary measures returned to baseline levels after 12 days. However, supervised (laboratory-based) wearable device assessment showed that gait impairments (increased step time) remained even after the athlete was cleared for return to play (2 months). Similarly, a 24-hour remote gait assessment showed changes in step time, step time variability, and step time asymmetry immediately after SRC and at return to play (1 month after SRC). Remote sleep analysis showed differences in sleep quality and disturbance (increased movement between immediately after SRC and once the athlete had returned to play [1 month after SRC]). CONCLUSION The concern about missed or delayed SRC diagnosis is growing, but methods to objectively monitor return to play after concussion are still lacking. This report showed that wearable device assessment offers additional objective data for use in monitoring players who have SRC. This work could better inform SRC assessment and return-to-play protocols. IMPACT Digital technologies such as wearable technologies can yield additional data that traditional self-report approaches cannot. Combining data from nondigital (traditional) and digital (wearable) methods may augment SRC assessment for improved return-to-play decisions. LAY SUMMARY Inertia-based wearable technologies (eg, accelerometers) may be useful to help augment traditional, self-report approaches to sports-related concussion assessment and management by better informing return-to-play protocols.

Abstract
BACKGROUND It is widely accepted that mouthguards are effective for injury protection in sports. However, findings on the effects of mouthguards in strength and power production remains controversial. Therefore, the aim of this study was to determine whether controlled-mandible position mouthguards influence strength and power production in well trained athletes. METHODS Twenty-two male amateur rugby players (25 ± 3.84 yrs; 1.92 ± 0.07 m; 93.91 ± 11.99 kg) volunteered for this study. Every participant performed an 1RM bench press test (113.20 ± 16.83 kg) to determine his maximal strength. In a randomized order, a ballistic bench press using 40% of the obtained 1RM (44.93 ± 6.76 Kg) was performed in a guided bar attached to a linear position transducer (LPT) for the following conditions: a) no mouthguard (CON); b) controlled mouthguard (MCM - jaw in centric relation); c) non-controlled mouthguard (NCM) and d) occlusal splint (OS). Vertical dimension of occlusion was also assessed for each of the testing conditions. RESULTS Athletes using a controlled mouthguard demonstrate a significant (p < 0.05) higher peak acceleration and peak force than those using no mouthguard. Additionally, when analysing the results of vertical dimension of occlusion, a significant difference (p < 0.05) was observed between controlled mouthguard and the other tested conditions. CONCLUSION Controlled mouthguards enhance peak force and peak acceleration in the ballistic bench press exercise without negatively affecting any other measure assessed in this study. We speculate that this is possibly due to an increased stability of temporomandibular joint.
