The purpose of this paper is to propose a five-stage process for establishing both validity and reliability in new systematic observation instruments. The process is contextualized within the working behaviors of elite level rugby union coaches within the practice setting. The sequential stages began with observer training and progressed through the identification of coaching behaviors through induction (to establish content validity), to establishing face validity through a domain-referenced test. The objectivity and reliability of the developed behavioral classifications are determined through an interobserver agreement test while, finally, the researcher’s ability to reliably reproduce data with the developed instrument is determined using a test/retest intraobserver reliability check. The developed instrument (the Rugby Union Coaches Observation Instrument: RUCOI) is deemed able to record the situationally unique behaviors arising from the nature of the sport and of the elite standard, both of which were considered to impinge upon the pedagogical process in the said context.

Physical training, testing, and monitoring are three key constitutes of athlete physical performance; however, there is a currently a lack of information on the prevalence of such methods in amateur boxing. This study aimed to explore the physical preparation practices of senior elite (SEB) and senior development (SDB) amateur boxers, and to determine whether these practices were discriminated by competitor level. One hundred and one amateur boxers (SEB n = 59, SDB n = 42) were surveyed on their understanding, perceptions and application of physical training, monitoring, and testing practices. SEB were associated with strength/power training (SEB 78%, SDB 50%, P = 0.005), monitor of training intensities (SEB 68%, SDB 40%, P = 0.006), and performing regular fitness testing (SEB 76%, SDB 50%, P = 0.006), compared to SDB. Likewise, SEB were twice as likely (56%) to have their physical preparation managed by a strength and conditioning (S&C) coach or sport scientist, compared to SDB (26%; P = 0.005). For the first time, these data demonstrate the extent to which competitor level is associated with preparatory practices in amateur boxing. Cost was identified as the main barrier in implementing several forms of scientific support in SDB. These data serve as a framework to enhance preparatory practices across different competitor levels in amateur boxing. This might include boxer and coach education on the benefits to a more scientific approach, and the use of cost-effective methods to develop, monitor and assess amateur boxers physical performance. This may be of particular importance where boxers are not funded, such as the SDB in the current study. However, this work may also be used to emphasise the importance of strength/power training, physical fitness testing and monitoring at the elite level of amateur boxing.

ABSTRACTObjectivesLower limb posterior chain injury (PCI) is common amongst athletic populations, with multi-factorial risk factors including age, previous injury, strength measurements, range of motion and training load. Biomechanics are commonly considered in the prevention and rehabilitation of PCI by performance staff. However, there is no documented testing method to assess for associations between biomechanics and PCI. The aim of this study was to investigate whether there is an association between an easily applicable, novel biomechanical assessment tool and PCI.MethodsFifty male elite-level rugby union athletes (age 22.83±5.08) participating in the highest tier of England were tested at the start of the 2019 pre-season period and PCIs (N=48) were recorded over the 2019/20 playing season. Participants’ biomechanics were analysed using two-dimensional video analysis against an Injury Risk Score (IRS) system in the performance of the combined movement – prone hip extension and knee flexion. Participants’ biomechanics in carrying out this movement were scored against the 10-point IRS, where the more compensatory movement recorded sees an increase in an individual’s IRS. Participants’ IRS were then compared against the number of PCI sustained and Spearman’s correlation coefficient was utilised for analysis.ResultsThere is a good significant association between IRS and PCI (R=0.573, p<0.001). Linear Regression demonstrated that an increase of 1 in IRS was associated with a 35% increase in PCI incidence (R2=0.346).ConclusionA good significance between the IRS and PCI provides preliminary support for its use as an injury risk assessment tool.

Increased professionalism in rugby has resulted in national unions developing high-performance models for elite player development, of which physical preparation is an important component, to ensure success in future years. This article presents a 5-step framework for the physical preparation of elite players in a development program. Competition movement patterns and the physical profiles of elite players are used as the basis of the framework and reinforce the repeated high-intensity nature of Rugby Union. Physical profiling highlights a player’s strengths and weaknesses in the areas of strength, speed, endurance, and body composition. These qualities need to be managed with an understanding of their interaction. This framework should be implemented within the yearly plan to ensure that benefits are maximized from the training undertaken. The success of the framework in developing elite players’ progression can be evaluated using standardized physical, performance, and competency tests.

In rugby union, effective defensive play is highly technical and essential for game outcomes. Therefore, the aim of this study was to identify tackle heights, for given tackle types, that had a greater propensity to result in tackle gainline success for the tackler using match video evidence. The results indicated that tackling the upper legs of the ball carrier had a greater propensity to result in tackler success for both front-on (OR = 3.27; 95% CI = 1.34–7.95; p < 0.01) and side-on (OR = 5.31; 95% CI = 2.08–13.6; p < 0.01) arm tackles. For shoulder tackles, tackling at the lower trunk for front-on tackles (OR = 1.70; 95% CI = 1.04-2.79; p = 0.03) and the mid trunk for side-on tackles (OR = 3.11; 95% CI = 1.31–7.37; p < 0.01) had a greater propensity to result in tackler success. For smother tackles, tackling at the mid trunk had a greater propensity to result in tackler success during front-on (OR = 3.49; 95% CI = 1.81–6.74; p < 0.01) and side-on (OR = 5.11; 95% CI = 2.42–10.8; p < 0.01) tackles. The results highlight the importance of tackle height when coaching the tackle. The findings also suggest that technically proficient players can advance to more challenging contact techniques than aiming for the ball carrier’s centre of gravity.

Tackling is a major component of rugby union and effective attacking and defensive play are essential for game outcomes. In this study, a number of pre-contact, contact and post-contact tackle characteristics that had an influence on tackle gainline success for the ball carrier and tackler were identified using match video evidence from European Rugby Champions Cup games. A total of 122 front-on tackles and 111 side-on tackles were analysed. For each ball carrier and tackler characteristic, the Odds Ratio and 95% Confidence Interval were calculated based on a gainline success outcome. A Chi-Square and Phi and Cramer’s V calculation was also conducted. A Chi-Square test then identified any statistically significant differences (p < 0.05) for proficiency characteristics between playing position. For both the ball carrier and tackler, tackle characteristics that were indicative of strong and powerful tackle technique such as ‘explosiveness on contact’ and ‘leg drive on contact’ were effective for achieving the desired gainline outcome. Playing position had an influence on only two proficiency characteristics that were statistically significant for gainline success: ‘fending into contact’ for ball carriers and ‘straight back, centre of gravity forward of support base’ for tacklers.
