Rugby Science Update 5

Activate is a 15–20min warm-up programme, designed to be completed prior to training and matches, with progressive, age-specific programmes. Neuromuscular training programmes such as Activate appear to have a dose–response relationship with injury rates, with three sessions per week providing the greatest preventative effect. The purpose of this study was to assess the effectiveness of Activate to lower match and training injury rates (incidence and burden) in schoolboy rugby union (under-12 to under-19). The secondary aim was to examine the dose–response relationship between weekly Activate adherence and injury incidence.

Individuals adopting Activate had a significantly lower training injury incidence than non-adopters, and lower match incidence and burden. Players completing Activate three times per week had significantly lower training and match incidence compared with those with low (<1 session) weekly adherence. Two-thirds of teams adopted Activate, with most completing Acti- vate three times per week. However, Activate was often not implemented as intended, with teams not using whole phases or failing to progress the programme.

Physical and Technical Demands and Preparatory Strategies in Female Field Collision Sports: A Scoping Review

Women’s participation in field collision sports is growing worldwide. Scoping reviews provide an overview of scientific literature in a developing area to support practitioners, policy, and research priorities. The aim of this study was to explore the published research and synthesise information on the physical and technical demands and preparation strategies of female field collision sports. 43 studies met the inclusion criteria. Physical demands were the most highly investigated (n=24), followed by technical demands (n-18), tactical considerations (n=8) and preparatory strategies (n=1). The key themes embody a holistic model contributing to both performance and injury prevention outcomes in the context of female field collision sports. Findings suggest a gender data gap across all themes and a low evidence base to inform those preparing female athletes for match demands. Given the physical and technical differences in match-demands the review findings do not support the generalisation of male-derived training data to female athletes.

Players’, parents’ and staffs’ perceptions of injury prevention exercise programmes in youth rugby union

In youth rugby union, there is a belief that the risk of injury is high and that injuries can be prevented; however, successful implementation of injury prevention exercise programmes in ball sports is limited by barriers such as lack of time, resources and player or staff attitude and motivation. Stakeholders’ attitudes and beliefs regarding injury risk and prevention are important to understand, as they play a role in the adoption of injury prevention exercise programmes. This study aimed to describe staff members’, players’ and parents’ knowledge and perceptions of injury risk, injury severity and injury prevention in youth rugby union in Australia and explore facilitators and barriers to performing an injury prevention exercise programme. Staff, parents and players agree that the risk of injury is high, that injuries can be serious and that preventing injury is important. Allied health staff such as strength and conditioning coaches should be considered a viable alternative to coaches where available, although coaches remain key influencers and leaders in this setting. Barrier themes to performing an injury prevention exercise programme included poor attitude or motivation of the players, limitations related to the programme, poor attitude or motivation of staff, and lack of leadership in implementation of the programme. Facilitators to performing an injury prevention exercise programme included positive behaviour change through the use of structure and routine, strong leadership displayed by coaches and/or administration with the creation of rules or policy, leadership through positive role modelling, positive attitude of the players, and positive attitude of the staff.

    The Return to Sport Clearance Continuum

    The purpose of this article is to explore the concept of Return To Sport (RTS) being part of an evolving continuum rather than the traditional notion that RTS is a single decision made at a discrete point in time. The authors describe a 5 phase continuum – the Return to Sport Clearance Continuum (RTSCC).

    The first phase is the repair phase, where initial healing occurs post surgery. This is where swelling will be minimized, range of motion will be increased, and proper muscle activation will occur. Next will be the rehabilitation and recovery phase, where normal arthrokinematics are going to be restored. Then, the athlete will move to the reconditioning phase, where the focus will be on skill and force development, along with load volume tolerance. The athlete will then progress to the performance phase, where the athlete will transition to full team practice and competition. Finally, they will progress to the preseason/training camp phase, where they will properly be managed for the upcoming season after injury. Throughout the continuum training loads need. to be monitored on a near daily basis when possible, to avoid overloading the healing tissues.

    Skill Training Periodization in “Specialist” Sports Coaching

    In this paper, the authors propose a skill training periodization framework for “specialist coaches” based on skill training theory. Skill Training can be divided up into coordination training, skill adaptability training and performance training.

    Strength and conditioning in schools: a strategy to optimise health, fitness and physical activity in youths

    In this editorial, the authors argue that schools are an ideal environment for mass implementation of strength and conditioning interventions to support youth development. The author recommend that schools should aim to systematically incorporate strength and conditioning and wider physical activity into year-round timetables. This could be achieved by employing qualified youth strength and conditioning practitioners, and/or educating and upskilling current staff and stakeholders.

    A game for all shapes and sizes? Changes in anthropometric and performance measures of elite professional rugby union players 1999–2018

    This study aimed to assess the longitudinal changes in mass, velocity, momentum and peak kinetic energy using two decades of standardised elite and international rugby player data. The study showed that professional players are now leaner, heavier, faster and cover more distance than ever before. When professional rugby players collide, the forces involved have also risen. The implications of these findings however are yet to be fully understood.

    Poor isometric neck extension strength as a risk factor for concussion in male professional Rugby Union players

    This study aimed to establish if reduced neck strength was a risk factor for concussion in professional male rugby players. The study identified a specific neck strength range associated with increased concussion rates and found that reduced neck extension strength is a risk factor for concussion in male professional rugby players.

    Effectiveness of the Activate injury prevention exercise programme to prevent injury in schoolboy rugby union

    The main aim of this study was to assess the effectiveness of Activate (a 15–20 min warm-up programme) to lower match and training injury rates (incidence and burden) in schoolboy rugby union (under-12 to under-19). A secondary aim was to examine the dose–response relationship between weekly Activate adherence and injury incidence. The study found individuals playing for teams adopting Activate had a lower match and training injury incidence when compared with those not using Activate. Individuals with high weekly Activate adherence (≥3 Activate sessions per week) had a lower match and training injury incidence than those with low adherence (<1 Activate session per week). Therefore, Activate appears effective at lowering injury risk in schoolboy rugby union, with maximum benefit when completing the programme three times per week.
