Insights into coaching effectiveness: Perspectives from coaches and players in South African Women’s Rugby

The aim of this study was to explore the perspectives of coaches and players regarding coaching effectiveness in South African women’s rugby. Semi structured individual interviews were completed with 28 women’s rugby players and eight coaches who were actively involved in playing and coaching in South Africa. Five themes were generated based on the Coaching Efficacy Dimensions of the conceptual model of coaching efficacy:  Motivation, Technique, Game Strategy and Character-building. In the Motivation Efficacy theme, two sub-themes emerged: the motivational climate created by the coach and the motivational climate experienced by the players. Coaches’ behaviour plays a crucial role in fostering team responsibly, providing individual support for players’ needs, and demonstrating patience and passion for the sport. All these elements contribute to a motivational environment that enhances team satisfaction and performance. In the Technique efficacy theme, the sub-theme focused on coaching the physical, technical and tactical aspects of rugby. Coaches’ ability to teach and evaluate technical skills is essential. Players come from a diverse skill background, and different coaching strategies are employed to help players reach an adequate skill level. Junior players also noted that the steep learning curve they face when they first arrive. Under the Game Strategy efficacy theme, the sub-theme centred on guiding the players to successful outcomes. Coaches in this study emphasized the importance of confidence, coaching the fundamental skills for newer players, and managing players’ behaviour to ensure team success. One coach also highlighted the significance of patience when working with women’s players to maintain engagement and understanding. The final theme, Character-building efficacy, included the sub-theme of cultivating a positive environment for holistic development and sportswomenship. Some coaches allow senior players to serve as role models, leading by example and celebrating small victories. Integrating these findings into coaching development frameworks can help ensure supportive and effective environment for women’s rugby players in South Africa.

The association between resistance training volume load and session rating of perceived exertion in junior developmental female rugby league athletes

The aim of this study was two-fold: 1) to determine the associations between changes in resistance training volume load and session RPE in female junior rugby league athletes throughout a competitive season, and 2) to identify which types of resistance training demonstrated the greatest associations with reported session RPE. Twenty-one (n =21) junior developmental female rugby league athletes performed two to three resistance training sessions each week for a 20‐week period (8 weeks preseason, 11 weeks in-season and one week off). The resistance training sessions incorporated a combination intended outcomes, such as enhanced power, maximal strength or hypertrophy development. Players provided a verbal rating of perceived exertion using the Borg CR‐10 scale within 20 minutes after the session in isolation. To quantify the external load of the resistance training sessions, the volume load method was utilised (volume load = sets x reps x weight lifted [kg]). The study found significant inverse relationships between a decrease in the session RPE, with increases in both absolute and relative overall volume load. Specifically, dynamic efforts and lower body plyometric efforts displayed significant inverse relationships with session RPE. Additionally, significant positive relationships were observed between an increase in session RPE and increases in the volume load for lower‐body and upper‐body repeated efforts, as well as for upper‐body plyometric efforts and maximal efforts. These findings highlight the usefulness and importance of the volume load method for monitoring and prescribing resistance training in female rugby league athletes, as looking at overall volume load in isolation can provide an inaccurate representation of the training session. Furthermore, it provides useful data for the planning of specific exercises within the in‐season training week.

Physical collisions during elite rugby league match play and training: A stakeholder’s perspective

The aim of this study was to gain insights from current key European Super League stakeholders about their experiences and understanding of collision. Nineteen (n = 19) stakeholders participated in one-on-one semi structured interviews. Five themes were derived from the interviews: simultaneous contact in the three-person tackle; tackle height – calibration is critical; the fundamental factors influencing tackle-related risks; the graded exposure and philosophical approaches to contact training and games and replacing toughness with resilience – the impact of game identity. Some stakeholders believed that the simultaneous tackle was the safest and most efficient way to win a tackle. There were contrasting viewpoints regarding tackle height. While some stakeholders felt it should be addressed, others thought that reducing tackle height still presented a significant risk to health and safety. In discussing the role of fatigue in tackle related risks, some stakeholders believed the speed of the match speed and amount of ball-in-play increased the risk of injury due to fatigue. Stakeholders also identified the out-the-back pass as one of the most challenging positions for an attacker, and some believed that certain attacking techniques, potentially overlooked, could help reduce concussions. Lastly, coaches noted that the greater the closing distance, the higher the injury risk. However, they believed that coaches could guide the types and intensities of tackles players make in both training and match play. A few coaches emphasized that additional tackle training sessions could improve timing and coordination when performing tackles and this should not be avoided. The importance of mental preparation for collisions, driven through physical exposure emerged in the final theme. Furthermore, graded exposure to enhance mental preparation for collisions was encouraged. Coaches in this study noted the correlation of mental toughness with successful sports performance, as well as the prevalence of depressive and anxiety symptoms amongst players. These findings may inform coaching and safety programmes in rugby league and could might aid in the development of  injury prevention strategies.

Tackle characteristics associated with suspected concussion in female varsity rugby union: a case-control video analysis study

The aim of this study was to examine the association between tackle characteristics and suspected concussion-related versus non-injurious tackle events in a Canadian female varsity rugby cohort using video analysis. Video footage from Canada West female varsity rugby union league, spanning 2017 to 2019, were analysed. A case-control study design was employed to evaluate the relationship between tackle characteristics and a suspected concussive tackle event. Tackle and head impact characteristics, such as contact direction, location, intensity, were coded. In total, 13 439 tackles were identified. Among 151 225 suspected injury events identified, 26% were classified as suspected concussions. Of these, 78% were attributed to tackle events, while the remaining concussions resulted from other match events, such as a scrums, mauls, or rucks. A high head impact intensity score was strongly associated with concussion for both ball carriers and tacklers. Tackler related suspected concussions were linked to tackle events involving three tacklers in a tackle event, a tap tackle and an away pre-contact head position. Ball carrier related suspected concussions were associated with a tap tackle, illegal tackle type and down pre-contact head position. Concussion prevention programmes and strategies should be prioritised in rugby. The findings of this study can guide the development of strategies and programmes focused on tackle types and head positioning for both tacklers and ball carriers.

‘Mind your head’, tackle characteristics associated with concussions in rugby league: A case-control study

The purpose of this study was to identify tackle characteristics associated with clinically diagnosed concussions in the men’s rugby league. Additionally, it aimed to determine the tackle characteristics that predict concussions in rugby league. Match concussions were reported throughout the 2018-2022 Super League seasons and were analysed using video analysis by the research team. In total, 7415 tackles that did not involve concussive events were coded, alongside the analysis of 196 concussions. Seventy percent (70%) occurred to the tackler, while thirty percent (30%) occurred to the ball carrier. Key tackle characteristics associated with concussions included the tackle impact location on the ball carrier’s body, the ball carrier leading arm, the number of defenders in the tackle, and the interaction of body positioning between the ball carrier and tackler. Specific characteristics for tacklers included tackler head placement, the ball carrier leading arm, number of players in the tackle, and tackle impact zone location on the ball carrier. For ball carrier concussions, tackle impact zone location on the ball carrier and the ball carrier and tackler body position. Tackle technique interventions should prioritise proper head placement to minimize direct impacts to the tackler’s head. Interestingly, this study found that the greatest odds of concussion occurred when both players were falling or diving rather than remaining upright. Tackles involving one ball carrier and three tacklers were the most frequent tackle type and had the lowest odds of causing concussion.  Prioritising strategies focused on the tackler may significantly reduce overall concussions. Interventions should address initial impact with the ball carriers’ head or neck to decrease ball carrier concussions. Further research into optimal techniques for both ball carrier and tackers is needed. The findings of this study suggest that modifying and reinforcing tackle laws could help reduce the incidence of concussions in rugby league.

What do coaches want? Exploring the preferences of youth rugby union coaches for education in the implementation of injury prevention programmes

The aim of this study was to explore youth Rugby Union coaches’ preferences for education and support in implementing injury prevention programmes. Five focus group were conducted in 2023, involving twelve Rugby Union coaches from secondary school teams and youth clubs in Ireland. Data were collected until data saturation was reached, and a conventional content analysis approach was used to analyse the data and address the research question. Three main categories emerged from the analysis:  1) Formal/non-formal learning, 2) Informal learning, and 3) Intrapersonal considerations. Coaches expressed a preference for live, structured, and practical workshops during the pre-season period, which a strong focus on developing knowledge. The emphasized that injury prevention workshop should also be a stand-alone session to allow full attention to the topic. Coaches also requested active resources to aid in planning their programmes. These resources would enable coaches to develop implicit knowledge of injury prevention programmes through various means, including adapting, integrating, and engaging in Q&A sessions. Coaches also sought the flexibility to adjust programmes as needed. The study identified a mismatch between coaches’ preferences for injury prevention programme education and what is currently offered through National Governing Bodies coach education programmes. Further exploration of perspectives of National Governing Bodies is necessary to address this gap.

“Women shouldn’t play rugby” – the gendered and embodied experiences of women players in rugby union

The aim of this study to understand the attitudes, experiences and behaviours of women rugby players concerning tackle performance and safety. In depth, semi-structured interviews were conducted with twenty-one senior women rugby players. A constructivist grounded theory approach guided the recruitment of participants, data collection and data analysis. The results were divided into two categories: 1) The position of women’s rugby and 2) how women shape the field of rugby. Participants discussed how their bodies felt ‘out of place’ within the rugby community due to their personal experiences and restrictive gender norms. This included deeply embedded gender norms within social and organisational structures, playing conditions and societal perceptions of women’s rugby, which limited their opportunities to safely participate and thrive in the sport. Despite these challenges, players did not change themselves to fit in, rather, they embraced the diversity of women’s embodiment and capabilities. They continued to participate in this sport, actively re-shaping the future of women’s rugby. The authors mentioned that participants expressed optimism about the future public profile of women’s rugby, and this positive attitude could serve as a catalyst for changing attitudes and increasing support. The authors recommend that researchers continue to build on this research by investigating the why and how certain knowledges and practices become normative, as well as when and why they may be resisted.

Twenty year analysis of professional men’s rugby union knee injuries from the English premiership shows high rates and burden

The aim of this study was twofold: (1) to describe the incidence, severity and burden of knee injuries over 20 English Premiership rugby seasons in matches and training, and (2) to assess changes in injury rates over time and compare these rates across different playing surfaces and between types of playing events. Data on injuries and match and training exposure were collected from first team male rugby players of Premiership Rugby Clubs from 2002/2003 season to the 2022/2023 season. All injury definitions were aligned with the 2020 IOC injury consensus document. Over the 20 seasons, a total of 2128 knee injuries reported, with 71% occurring during matches and 29% during training. Annually, knee injuries accounted for an average of 11.6% of all match injuries and 9.5% of all training injuries. The mean knee severity in matches was 50 days, with an injury incidence of 9.8 injuries per 1000 player hours. MCL injuries were the most common during matches; however, ACL injuries had the highest severity (241 days) and injury burden (112 days per 1000 hours). In training, the mean severity of knee injuries were 51 days, and the injury incidence was 0.2 injuries per 1000 player hours. MCL, chondral/meniscal, and ‘other’ knee injuries were the most common in training, though ACL injuries had the highest severity (243 days). While the overall knee injury count did not change over time, counts of PCL and complex knee injuries have significantly increased. Average knee injury severity also showed a significant increase over time. Knee injury rates during matches were 44% higher on artificial grass pitches than on natural grass surfaces. The tackle event was the leading cause of knee injuries in matches, with ball carrier at a higher risk than tacklers. For ACL injuries, running accounted for 33% of cases, followed by the tackle event with 31%. Given the evolving nature of the game, prioritising knee injury prevention strategies is recommended.

Minimal influence of the menstrual cycle or hormonal contraceptives on performance in female rugby league athletes

This study aims to examine performance across the menstrual cycle and compare athletes using hormonal contraption with those having a “natural” cycle. Twenty-four national Australian National Rugby League’s Indigenous Women’s Academy athletes participated in this study while attending a 5 week training camp. The players were divided into two groups: those using hormonal contraception and those reporting naturally menstrual cycles. After two familiarization sessions, participants completed performance tests on three separate occasions, aligned with each participant’s individualized menstrual (MC) or hormonal contraceptive cycle. Menstrual status was tracked for all athletes by recording the onset of bleeding, conducting 11 weeks of MC or hormonal contraceptive tracking, using dual hormone urinary ovulation kits, and analysing retrospective serum 17‐β‐estradiol and progesterone concentration. Performance tests were administered at MC phase one, two and four for natural menstruating athletes and three equally spaced out intervals for athletes using hormonal contraceptive athletes. Blood samples were collected from each athlete before each performance testing session. Performance tests included the countermovement jump (CMJ), squat jump (SJ), and isometric mid‐thigh pull, conducted on a dual force plate system, followed by the power pass, 20m sprint and the Stroop Colour and Word Test. No differences or changes were observed in CMJ, SJ, and isometric mid‐thigh pull force, power pass distance, 20m sprint times or Stroop effect across MC phases, test sessions, or between groups. However, small variations in kinetic and kinematic outputs were noted in the CMJ and SJ: a 16.8% greater mean concentric power were observed in the CMJ, and a 4.7% reduction in impulse at 50 ms in the SJ during MC phase four compared to MC phase one. This study suggests that while the menstrual cycle or hormonal contraceptive use does not significantly impact physical and cognitive performance outcomes, certain kinetic or kinematic outputs during the CMJ and SJ may experience minor alterations.
