OBJECTIVES: Due to the complex systems nature of injuries, the responsibility for injury risk management cannot lie solely within a single domain of professional practice. Interdisciplinary collaboration between technical/tactical coaches, strength and conditioning coaches, team doctors, physical therapists and sport scientists is likely to have a meaningful impact on injury risk. This study describes the application and efficacy of a multidisciplinary approach to reducing team injury risk in professional rugby union...

There is mounting evidence of reduced long-term cognitive ability in rugby players, even in those without a reported history of concussion. The tackle height law is an area of controversy. However, little is known about the effects of repetitive inertial head loading in rugby. Furthermore, the magnitude and influencing factors for head kinematics are generally unknown. In this exploratory study, 45 multibody front-on shoulder tackles simulated with the MADYMO pedestrian model and 20 staged rugby tackles executed by professional rugby players in a marker-based 3D motion laboratory were used to assess the effect of tackle height on ball carrier head kinematics...

The 2017 Berlin Concussion in Sport Group Consensus Statement provides a global summary of best practice in concussion prevention, diagnosis and management, underpinned by systematic reviews and expert consensus. Due to their different settings and rules, individual sports need to adapt concussion guidelines according to their specific regulatory environment. At the same time, consistent application of the Berlin Consensus Statement's themes across sporting codes is likely to facilitate superior and uniform diagnosis and management, improve concussion education and highlight collaborative research opportunities...

Self-reported wellness is often used to monitor fatigue responses to training and competition. Constraints within team sports mean short-form wellness questionnaires are typically preferred to literature-validated documents. This research aimed to assess the relationship between self-reported wellness and neuromuscular performance during a professional rugby union season, and to identify changes in these parameters over a 12-week period. On the first training day each week, prior to activity, 37 players rated 5 wellness subscales ('fatigue/vigour', 'upper-body soreness', 'lower-body soreness', 'mood', 'sleep quality/duration'), on a 1-5 Likert scale (1 representing the lowest wellness), and 5-repetition countermovement jumps (CMJ) were completed following a warm-up...

Rugby is a worldwide intermittent team sport, players tend to be heavier than the majority of similar team sport athletes on whom the dietary guidelines have been developed. Therefore, the aim of the current review was to describe the intakes of rugby union players. Article databases were searched up to February 2017 and were included if they were published in English and reporting dietary intakes of male rugby union players. Of the research articles found energy intakes were lower than four of the five studies which reported intakes and expenditure, which would suggest the players were losing weight which is somewhat supported by the decreases in skinfolds seen during pre-season...

Background: World Rugby Union laws are constantly evolving towards stringent injury-prevention, particularly for contested scrums, since front row players are most at risk of cervical spine injuries. Recently, some countries have also introduced tailored training programs and minimum performance requirements for playing in the front row. Nevertheless, these approaches lack an objective assessment of each cervical muscle that would provide protective support. Objective: Since front row players are the most at risk for cervical spine injuries due to the specific type of contact during scrums, the purpose of this study was to ascertain whether significant differences exist in neck muscle size and range of motion between front row players and players of other positions, across playing categories...

CONTEXT: Rugby union is the most widely played team collision sport globally. As with other contact sports, there is substantial risk of injury. To date, the majority of studies on injury epidemiology have focused on elite male cohorts, which inherently prevents extrapolation of research findings to other groups within the player continuum. This review aims to describe emerging injury trends across the spectrum of various rugby union subpopulations and to highlight gaps that may influence future injury prevention tactics...
