- Description: Background: The rate of participation in community-based sport by boys and men has been double that of girls and women. Contributing to this is the fact that some sports have been traditionally male-only or at least very male-dominated. Aim: The aim of this study was to investigate changes in participation in sport by sex and age across 10 major sports in Australia over a 5-year period. In conjunction with the analysis of participation trends, the gender strategies that were developed and implemented during this time are reviewed. Methods: This study encompassed all sport participants registered with one of 10 State Sporting Associations in Victoria, Australia in 2015 and in 2019. Participation rates by region, age and sex were calculated. State sport and health policies relating to female participation in sport were reviewed. Results: There were 749,037 registrations in 2015 and 868,266 in 2019. A comparison between 2015 and 2019 shows increases in participation for women and girls across all age groups (4–84 years), and highest increases for those aged 4 (6.6%) and 5–9 (4.7%). For boys there was a considerable decrease in participation for those aged 5–9 years (−3.8%). Discussion: This study provides evidence that whilst participation in sport is still dominated by males, the gap might be gradually closing and this is in line with recent strategies and investments into sport and wider cultural developments in society. The implications of these findings are discussed. Copyright © 2021 Eime, Charity, Harvey and Westerbeek.

- Description: Background: Throughout the ecosystem of sport, women have been and continue to be underrepresented at all levels compared to men. The capacity of community-level sport is heavily reliant on the many non-player roles including governance, as well as administration, coaching and officiating. Recently there has been increased attention to improving the gender balance in sport. The aim of this study is to investigate the proportions of women engaged in non-playing roles in sport (2016–2018). Methods: This study involved secondary analysis of the AusPlay survey, a national population survey, funded by Sport Australia. This study utilised data from people aged 15-years or older about their involvement in non-playing roles in sport, and their demographic data. Survey respondents were asked “During the last 12 months, have you been involved with any sports in a nonplaying role, such as official, coach, referee, administrator, etc?” Analysis of non-player role responses focussed specifically on the top four non-player role categories; coach, official, administrator and manager. Frequency analysis concentrated on the distribution of men and women involvement in a non-player capacity for the three years, with detailed analysis of the most recent year (2018). Results: In this study of 61,578 Australians there was a higher proportion of men in non-player roles in sport compared to women, across each of the three years (2018: men 55 %, women 46 %). Involvement of women in coaching increased significantly from 38 % to 2016 to 44 % in 2018 (p < 0.001). The proportion of women involved in administration roles significantly decreased from a peak of 51 % in 2017 to 46 % in 2018 (p < 0.001). Conclusions: Aligned with strategic policy and investment strategies, there are gradual increased representation of women in non-playing sport, coaching roles. Women are still underrepresented in terms of coaches, officials and administrators, but are more likely to be managers. It is recommended that there is continued mentoring, identification and emphasising of female role models, and further strategies to increase female presence in non-playing roles. We recommend that future research, in line with appropriate gender and cultural-change theories, investigates and discusses the progress of gender equality throughout playing and non-playing role in sport. © 2021, The Author(s).

- Description: Researchers who examine existing models of choking under pressure are beginning to explore the antecedents that predispose individuals to increased anxiety. Irrational beliefs (IBs) may be one such antecedent to “choking”, given that irrational beliefs are closely associated with anxiety intensity. This study aimed to investigate whether IBs influenced anxiety and performance under pressure. Experienced Australian football players (N = 35) completed an IBs questionnaire prior to an Australian football set shot experiment with low- and high-pressure. During both pressure conditions, participants completed a state anxiety questionnaire prior to completing 15 set shots on goal. Results indicated that cognitive and somatic anxiety increased from low- to high-pressure. For somatic anxiety, an IBs main effect approached significance, indicating higher somatic anxiety with increases in IBs. A marginally significant Condition main effect was found for performance, which decreased from low- to high-pressure, with no other effects for performance evident. Follow-up correlation analysis of seven athletes who likely experienced choking (i.e., greater than 15-point performance decrease) indicated a strong negative correlation between IBs and change in performance from low- to high-pressure. Further analyses for “chokers” indicated a significant IBs × Condition interaction, with performance tending to increase with increasing IBs under low-pressure and decrease with increasing IBs under high-pressure. This study provides initial, tentative support that IBs associated with performance trends of “chokers” under different pressure conditions may be dissimilar to those of “underperformers” or “clutch” performers. Applied implications for sport psychologists working with athletes are discussed. Lay summary: This paper investigated whether inflexible thoughts (i.e., irrational beliefs- IBs) led to increased anxiety and “choking”. Athletes completed an IBs questionnaire, then an anxiety survey during a football kicking task under low- and high-pressure. Results indicated IBs may affect “chokers” response to pressure differently to other groups. © 2020 Association for Applied Sport Psychology.

- Description: Background: Poor motor skills are an increasing issue for adolescents in our local communities. In regional Victoria, almost 20% of children starting school in 2018 were considered at risk or developmentally vulnerable in the domain of physical health and wellbeing. Purpose: The aim of the current study was to examine factors (how adolescents perceive their fine and gross motor skills, activities of daily living, comparison to peers) of motor competence that may be important to adolescents in regional Victoria, Australia, using the Adolescent Motor Competence Questionnaire (AMCQ). Methods: A sample of 183 Australian adolescents ([138 females (Mage = 15.59 years, SD = 1.56); 45 males, (Mage = 15.82 years, SD = 1.95); 12–18 years old] completed the AMCQ. Results: The mean AMCQ score was 87.86 (SD = 7.55), with no significant difference between males (M = 89.67 SD = 7.29) and females [M = 87.28 SD = 7.56; t (181 = 1.86 p =.065)]. A Principal Component Analysis (PCA), extracted five factors (Eiqenvalue of 1.389) explaining 43.46% of variance, representing, Ball Skills and Kinesthesis; Activities of Daily Living; Fine Motor and Gross Motor; Proprioception and Exteroception; Public Performance. Conclusion: The results highlight key factors important in describing an adolescent’s motor competence within regional Victoria. With physical health a priority in local communities, understanding these factors is an important first, that which may inform development of physical activity interventions for adolescents. © 2020 SHAPE America.

- Description: Objectives: To conduct a document analysis of sports and leisure activity heat-related injury prevention resources in Australia and develop an understanding of the content within those resources. Design & Methods: Heat resources were included if they dealt specifically with, or could be extrapolated to, prevention of heat-related injuries. Collating strategies for the catalogue included: (1) a detailed search of the organisation's website and (2) an online search for sport specific heat resources. A content analysis of each resource was first performed, and descriptive codes were assigned to the data using qualitative data analysis software. Every coded text was recorded as an individual data point (n). Common sub-categories were identified by thematic analysis and collated under three broader categories. Results: A total of 468 data points were identified within the 64 heat resources found. Guidelines (n = 20) and policies (n = 18) were the most common type of resources followed by factsheets (n = 9), webpages (n = 8), laws and by-laws (n = 2). Three overarching categories emerged through the data analysis process: preventive strategies (n = 299, 63.9%), risk factors (n = 94, 20.1%), treatment (n = 75, 16.0%). Activity modification, which included information on rescheduling games and extra breaks, was the most common intervention. Cricket, soccer, swimming and triathlon had the most complete set of heat resources. Conclusions: The findings of this study provide an insight into the composition of heat-related sports injury prevention resources within Australia and identify areas for development. As the resources were incomplete for many sports, the development of more comprehensive heat safety resources is required to ensure the safety of participants. © 2021 Elsevier Ltd

- Description: Objectives: The purpose of this study was to establish beliefs and practices of physical performance coaches regarding sprinting and Hamstring Strain Injury (HSI) in Australian Rules football. Designs: Delphi-validated questionnaire. Setting: Online. Participants: Eighteen high-performance managers of the Australian Football League. Main outcome measures: Descriptive statistics were collected to establish experience; central themes were established for the analyses of the beliefs and practices. Results: Nine (50%) physical performance coaches responded to an invitation to complete the questionnaire. Participants held an undergraduate degree and had 9.2 ± 4.3 years of experience. Accelerations (n = 9), maximum speed sprints (n = 9) and running with hip flexion (n = 7) were the most common activities associated with HSI. Coaches believed sprinting, eccentric strength training and proper periodisation were effective strategies to reduce HSI risk. There's a disparity between beliefs and practices when using GPS to monitor sprinting, however, all coaches reported regular exposure to sprint training across both pre and in-season. Overstriding (n = 9) and pelvic instability (n = 6) were identified as key flaws in running mechanics. Conclusions: This information can be used to improve training strategies, whilst these findings indicate further investigations into sprint training and running mechanics for HSI risk reduction. © 2020 Elsevier Ltd

Design: Cohort Study. Setting: Non-clinical, state swim team training facility. Participants: A convenience sample of eight non-injured state and national level swimmers from a regional swim team were recruited for this study. Main outcome measures: Ultrasound measures of STT were collected in response to the two swimming practice sessions. Measures were taken prior to each swim practice; immediately after practice; 6-hours post practice and 24-hours post practice. Results: A significant increase in STT resulted from both the HI and HV (p < 0.05) practice immediately post practice. For the HI practice, the STT remained significantly thicker than pre-practice measures at the 6-hour post practice test (p < 0.05) however no longer significant 24-hours post practice. The difference in the change in STT between the HI and HV practice was significantly different immediately post practice and 6-hours post practice (p < 0.05) however no longer significant 24-hour post practice. Conclusion: Ultrasound measures of STT following different swimming volumes and intensities may provide information on shoulder tendon loads. © 2020 Elsevier Ltd

- Description: The changing social and policy context in which sport is produced, delivered, and consumed is considered as a foundation for proposing a new integrated framework that incorporates participation in sport with participation in leisure-time physical activity (PA) more broadly. In order to position sport in the broader context of leisure-time PA, the concept of physical literacy is reviewed and integrated into the theoretical foundations of a new lifespan framework. It is argued that historically, sport policy largely focused on competitive club-based sport and elite performance and that in line with this, talent development pathway models were developed and implemented. However, with increasing physical inactivity globally, these models do not apply to the general population. This is why we propose a population-based “whole of sport ecosystem” lifespan model—the Physical Activity and Sport Participation (PASP) framework. We conclude that this framework may serve as a holistic policy and implementation guide for all in the sport ecosystem. This includes governmental PA and sport policy makers, sport governing bodies and clubs, and the ever-increasing range of private PA and sport providers and also health agencies. In recognition of the changing patterns of participation in PA and sport across the lifespan, the PASP framework can contribute to coordinated and integrated PA and sport policy development, which, in turn, can lead to strategies that tackle the global physical inactivity crisis. © 2021 Westerbeek and Eime.

J Strength Cond Res 34(9): 2596-2607, 2020-This study investigated the efficacy of combined "general," "special," and "specific" resistance training on pace bowling skill. Twelve male, club-standard pace bowlers were randomly allocated to a combined resistance training (CRT) program or traditional cricket training (TCT) program for 8 weeks. The CRT group (n = 6) trained with 300, 250-g, and standard cricket balls; performed 20-m sprints with +20% and +15% body mass resistance (but also unresisted); and completed chin-up and pull-up training. The TCT group (n = 6) trained with standard balls and performed unresisted 20-m sprints. No statistically significant GROUP × TIME interactions were identified. The CRT group demonstrated a "clear moderate" enhancement in peak ball release speed (mean ±95% confidence limits [CLs]: 1.2 ± 1.5 m·s, d = 0.66 ± 0.83), a "clear large" increase in mean radial error (mean ±95% CLs: 7.1 ± 6.5 cm, d = 0.94 ± 0.87), and a "clear large" rise in bivariate variable error (mean ±95% CLs: 7.2 ± 7.8 cm, d = 0.97 ± 1.05). The TCT group exhibited "unclear" changes across all pace bowling skill measures. Both groups displayed "unclear" changes in approach speed, 20-m sprint time, and 1 repetition maximum pull-up strength. In 8 weeks, the CRT program improved peak ball release speed, but at the cost of poorer bowling accuracy and consistency of bowling accuracy. These findings could be attributed to bowling with the heavier balls. The inclusion of "specific" resistance training does not seem to be effective in enhancing all-round pace bowling skill in club-standard cricketers.

- Description: Background: While there is a long history of measuring death and disability from injuries, modern research methods must account for the wide spectrum of disability that can occur in an injury, and must provide estimates with sufficient demographic, geographical and temporal detail to be useful for policy makers. The Global Burden of Disease (GBD) 2017 study used methods to provide highly detailed estimates of global injury burden that meet these criteria. Methods: In this study, we report and discuss the methods used in GBD 2017 for injury morbidity and mortality burden estimation. In summary, these methods included estimating cause-specific mortality for every cause of injury, and then estimating incidence for every cause of injury. Non-fatal disability for each cause is then calculated based on the probabilities of suffering from different types of bodily injury experienced. Results: GBD 2017 produced morbidity and mortality estimates for 38 causes of injury. Estimates were produced in terms of incidence, prevalence, years lived with disability, cause-specific mortality, years of life lost and disability-adjusted life-years for a 28-year period for 22 age groups, 195 countries and both sexes. Conclusions: GBD 2017 demonstrated a complex and sophisticated series of analytical steps using the largest known database of morbidity and mortality data on injuries. GBD 2017 results should be used to help inform injury prevention policy making and resource allocation. We also identify important avenues for improving injury burden estimation in the future. © Author(s) (or their employer(s)) 2020. Re-use permitted under CC B Y.

- Description: OBJECTIVES: Sport injury is the leading cause of hospitalization in Canadian youth and represents a high burden to the health care system. This study aims to describe the facilitators and barriers to implementation of a sport injury prevention program in junior high school physical education (known as iSPRINT), previously shown to reduce the risk of sport-related injury in youth (age, 11-15 years). METHODS: Focus group data were mapped onto constructs from the Consolidated Framework for Implementation Research (CFIR). Four schools that implemented iSPRINT participated in this study. Forty-seven key stakeholders (teachers, students, principals) participated in 9 semistructured focus groups and 4 interviews. The CFIR was used to guide the focus group discussions, data coding, and analysis using a qualitative content analysis approach. RESULTS: Of the 22 applicable CFIR constructs, 16 were identified in the transcripts. The most significant facilitators to successful implementation efforts included evidence strength and quality, adaptability, implementation climate, culture, and having a high level of compatibility facilitated successful implementation efforts. Barriers to implementation included intervention complexity, planning, and readiness for implementation. Constructs that acted as both a facilitator and a barrier, depending on the context, were self-efficacy, execution, and individual identification with the organization. CONCLUSIONS: Participants in this study reported positive attitudes about implementing iSPRINT, citing evidence strength, adaptability, and constructs related to the organizational setting that contributed to successful implementation. Potential improvements include modifying certain program components, decreasing the number of components, and reducing the equipment required.

- Description: Patellar tendinopathy (PT) is a leading cause of morbidity in jump-landing athletes. Landing mechanics are identified as a factor associated with PT and/or patellar tendon abnormality. This study aimed to identify key jump-landing variables associated with PT. Thirty-six junior elite basketball players (men n = 18, women n = 18) were recruited from a Basketball Australia development camp. Three-dimensional (3D) kinematic and ground reaction force (GRF) data during a stop-jump task were collected as well as ultrasound scans of the patellar tendons and recall history of training load data. Mixed-model factorial analyses of variance were used to determine any significant between-group differences. Of the 23 participants included for statistical analyses, 11 had normal bilateral patellar tendons (controls) and eight reported PT (currently symptomatic); however, the four participants categorized as asymptomatic with patellar tendon abnormality on diagnostic imaging were excluded from statistical analyses due to their small sample size. Athletes with PT displayed a similar knee flexion angle at initial foot-ground contact (IC) and hip extension strategy during a stop-jump horizontal landing. Despite a similar kinematic technique, athletes with PT utilized a strategy of a longer stance duration phase from IC to peak force. This strategy did not lead to those athletes with PT decreasing their peak vertical GRF nor patellar tendon force during landing but enabled these athletes to land with a lower rate of loading (control 59.2 +/- 39.3 vs. PT 29.4 +/- 33.7 BW.s-1). Athletes with PT still reported significantly reduced training volume (control 4.9 +/- 1.8 vs PT 1.8 +/- 1.1 sessions/wk; total training time/wk control 2.4 +/- 1.0 vs PT 1.4 +/- 1.1 h/wk).

- Description: PURPOSE: Habitual intense exercise may increase the incidence of upper respiratory symptoms (URS) in elite athletes. This study investigated whether immune gene expression could identify gene markers that discriminate athletes with a higher prevalence of URS. METHODS: This cross-sectional analysis of elite Australian athletes from various sports investigated whether athletes retrospectively reporting URS for two days or more in a month (n=38), had an altered immune gene expression profile compared with asymptomatic athletes (n=33). Peripheral blood samples were collected during Olympic selection events with corresponding URS data collected for the one-month period before sampling. Digital immune gene expression analysis was undertaken using the NanoString PanCancer Immune Profiling panel. RESULTS: Fifty immune genes were differentially expressed between the groups (p<0.05) and approximately 78% of these genes were more highly expressed in athletes reporting URS. Many of these genes were interferon-stimulated genes or genes involved in the Jak/Stat signalling pathway. Only interferon alpha inducible protein 27 (IFI27), an interferon stimulated gene involved in viral response, remained significantly higher in athletes reporting URS (log2 fold-difference=2.49, odds ratio 1.02 per unit increase; p<0.01) post-adjustment and discriminated athletes reporting URS from asymptomatic athletes with 78% accuracy. CONCLUSIONS: Expression of IFI27 could differentiate athletes reporting URS from asymptomatic athletes, a gene that is upregulated in the immune response to viral infection. Upregulation of viral signalling pathways provides novel information on the potential aetiology of URS in elite Olympic athletes. Copyright © 2020 International Society of Exercise and Immunology.

- Description: Background: Nordic walking (NW) is a potentially beneficial exercise strategy for overweight and obese people. To date, no reviews have synthesized the existing scientific evidence regarding the effects of NW on this population. This systematic review and meta-analysis aimed to identify the characteristics, methodological quality, and results of the investigations that have studied the effects of NW in overweight and obese individuals. Methods: Six electronic databases were searched up to June 2019 for studies that examined the effects of NW on people with a body mass index ≥ 25 kg/m2. The methodological quality of the included randomized controlled trials was retrieved from the physiotherapy evidence database or evaluated using the physiotherapy evidence database scale. Results: Twelve studies were included in the review. The investigations were mostly good-to-fair methodological quality. NW groups had a significant improvement on parameters such as fasting plasma glucose, abdominal adiposity, and body fat compared with the baseline, but no significant improvements were found when compared with control groups. Conclusions: NW can potentially lead to improvements in parameters related to major health outcomes in overweight and obese people. The lack of control for confounding variables in the analyzed studies prevents further elaboration on its potential benefits. © 2020 Human Kinetics, Inc.

- Description: New wave therapies such as Acceptance and Commitment Therapy aim to cultivate people's psychological flexibility in order for them to live a satisfying life. Psychological flexibility has also a role in promoting mental health, which may mediate the relationship with life satisfaction. The aim of this study was to determine whether mental health mediates the effect of psychological flexibility on life satisfaction. A convenience sample of 140 adults (32 males, M = 36.50 years, SD = 12.22; 107 females, M = 38.46 years, SD = 12.81; and a 45-year-old person of unknown gender) completed an online questionnaire assessing psychological flexibility, mental health and life satisfaction. Three of the four hypothesized components of psychological flexibility (experiential acceptance, cognitive alternatives and cognitive control) contributed to the latent construct of psychological flexibility, but cognitive defusion failed to contribute. Psychological flexibility had a direct, positive effect on life satisfaction and the hypothesis that mental health would mediate this relationship was supported. The results suggest that psychological flexibility is important for one's mental health and that both are integral to life satisfaction. The results also support a continued focus on third-wave therapies in cultivating psychological flexibility. © The Author(s) 2019. Published by Oxford University Press. All rights reserved.

Methods: Five electronic databases were searched. Included articles were required to: (1) investigate the 3D biomechanics of a jump-landing task; (2) be cross-sectional or longitudinal in design; and (3) include participants that had symptomatic PT, were asymptomatic with a history of PT, asymptomatic with PTA on diagnostic imaging and/or asymptomatic with an unknown pathology or PT history. Results: Thirty-seven statistically significant jump-landing variables were associated with PT, history of PT and/or PTA. The only consistent variable that could be replicated between studies was knee flexion angle at initial foot-ground contact (IC) and an altered hip flexion/extension strategy during a horizontal land phase of a vertical stop-jump. Conclusion: Isolated vertical landings or take-offs alone may not be sensitive enough to identify key jump-landing variables associated with PT, thus clinicians and researchers should incorporate a whole jump-landing task with a horizontal landing component. Sagital plane hip and knee kinematics in a horizontal landing phase appear to provide the most valuable information for evaluating those with PT. (C) 2020 Elsevier Ltd. All rights reserved.

- Description: Objective: Implementation of automated external defibrillators (AEDs) in community sports settings is an important component of emergency medical planning. This study aimed to understand motivations for why sports organizations participated in a government-funded program that provided AEDs and associated first-aid training. Design: Face-to-face interviews. Setting: Community sports organizations in Victoria, Australia. Participants: Representatives from 14 organizations who participated in a government-funded AED program. Main Outcome Measures: Motivations to participate in the AED program were explored using a qualitative descriptive approach. Results: Two overarching themes emerged: awareness of the program and decision to apply. Awareness was gained indirectly through grant advertising in newsletters/emails/web sites and directly through their sporting associations. For most organizations, there was no decision process per se, rather, the opportunity to apply was the key determinant for participating in the program. A duty of care also emerged as a key driving factor, with recognition of AEDs as a valuable asset to communities broadly, not just the participants' immediate sports setting. Reflecting on participation in the program, these participants identified that it was important to increase awareness about AED ownership and use. The program benefits were clearly summed up as being best prepared for a worst-case scenario. Discussion: This study provides new understanding of why community sports organizations apply for an AED and training. The strongest reason was simply the opportunity to acquire this at no cost. Therefore, for wider implementation of AEDs, additional funding opportunities, targeted awareness of these opportunities, and continued promotion of AED importance are recommended.

- Description: Background Though rare, rugby union carries a risk for serious injuries such as acute spinal cord injuries (ASCI), which may result in permanent disability. Various studies have investigated injury mechanisms, prevention programmes and immediate medical management of these injuries. However, relatively scant attention has been placed on the player's experience of such an injury and the importance of context. Aim The aim of this study was to explore the injury experience and its related context, as perceived by the catastrophically injured player. Methods A qualitative approach was followed to explore the immediate, postevent injury experience. Semi-structured interviews were conducted with 48 (n=48) players who had sustained a rugby-related ASCI. Results Four themes were derived from the data. Participants described the context around the injury incident, which may be valuable to help understand the mechanism of injury and potentially minimise risk. Participants also described certain contributing factors to their injury, which included descriptions of foul play and aggression, unaccustomed playing positions, pressure to perform and unpreparedness. The physical experience included signs and symptoms of ASCI that is important to recognise by first aiders, fellow teammates, coaches and referees. Lastly, participants described the emotional experience which has implications for all ASCI first responders. Significance All rugby stakeholders, including players, first responders, coaches and referees, may gain valuable information from the experiences of players who have sustained these injuries. This information is also relevant for rugby safety initiatives in shaping education and awareness interventions.

- Description: Background: Injuries are common in rugby sevens, but studies to date have been limited to short, noncontinuous periods and reporting of match injuries only. Purpose: To report the injury incidence rate (IIR), severity, and burden of injuries sustained by men and women in the Australian rugby sevens program and to provide the first longitudinal investigation of subsequent injury occurrence in rugby sevens looking beyond tournament injuries only. Study Design: Descriptive epidemiology study. Methods: Ninety international rugby sevens players (55 men and 35 women) were prospectively followed over 2 consecutive seasons (2015-2016 and 2016-2017). All medical attention injuries were reported irrespective of time loss. Individual exposure in terms of minutes, distance, and high-speed distance was captured for each player for matches and on-field training, with the use of global positioning system devices. The IIR and injury burden (IIR × days lost to injury) were calculated per 1000 player-hours, and descriptive analyses were performed. Results: Seventy-three players (81.1%) sustained 365 injuries at an IIR of 43.2 per 1000 player-hours (95% CI, 43.0-43.3). As compared with male players, female players experienced a lower IIR (incidence rate ratio, 0.91; 95% CI, 0.90-0.91). Female players also sustained a higher proportion of injuries to the trunk region (relative risk, 1.75; 95% CI, 1.28-2.40) but a lower number to the head/neck region (relative risk, 0.58; 95% CI, 0.37-0.93; P =.011). The majority (80.7%) of subsequent injuries were of a different site and nature than previous injuries. A trend toward a reduced number of days, participation time, distance, and high-speed distance completed before the next injury was observed after successive injury occurrence. Conclusion: Female players have a lower IIR than male players, with variation of injury profiles observed between sexes. With a surveillance period of 2 years, subsequent injuries account for the majority of injuries sustained in rugby sevens, and they are typically different from previous types of sustained injuries. After each successive injury, the risk profile for future injury occurrence appears to be altered, which warrants further investigation to inform injury prevention strategies in rugby sevens.
