Full textCurrently the performance of off-field managers of the Super League A rugby clubs is not at the required level, despite indicators that it plays a crucial role in the success of rugby clubs in the Western Province and in South Africa (SA). This study reviews and reports on the factors influencing off-field management of rugby clubs to understand management effectiveness and its importance to the success of the club. The review identified factors such as skills, competencies, strategic management, and other resources that are important for effective rugby club management, and reports on the need to develop and deploy adequate skills and resources to enhance rugby club management in the Western Province. The aim of this study was to investigate the importance of effective management of rugby clubs. The purpose of the study was to investigate the off-field management skills, competencies, and resources for effective management of Super League (SL) A rugby clubs in the Western Province Rugby Football Union (WPRFU). Emanating from this investigation, recommendations were made to improve SL A rugby clubs’ off-field management performance. The methodology that was used included questionnaires that were completed by employees at the rugby clubs, either electronically or in written form. The results were analysed using SPSS version 21. The main findings were that the off-field management needs training to be effective, and therefore should deploy identified, well-trained employees to fill the gap created by partly-trained employees. The practical implication is that rugby clubs need to invest in the training and development of off-field employees for effective management of rugby clubs.

Full textThis study examines professional Australian coach and athlete perceptions of effective coaching. Rather than assess the ability or effectiveness of the coaches and teams involved, the purpose was to gather perceptions of what professional coaches and players believe it takes to be an effective coach. Given the broad range of tasks that fit under the auspice of coaching, an important question to address was ‘what’ a coach does in order to be considered effective. In addition, an understanding of ‘why’ and ‘how’ these factors are effective was also essential. These questions formed a starting point in order to find out what professional coaches do (including how they behave), and why players and coaches perceive certain coaching strategies to be effective. This study employed a qualitative research design to identify perceptions about, and strategies of, effective coaching within the professional sport context. Interviews enabled participants to discuss their interpretations of the world in which they live, from their own point of view – a key feature of the present research. Observational data allowed me to view coaching behaviours and interactions with players in training and competition contexts. Using professional Australian coaches and players from cricket, rugby union and rugby league, 6 coaches and 25 players were interviewed while up to 16 coaches and 80 players were observed during 41 observation sessions at training and competition venues. The constant comparative method (Côté, Salmela, Baria, & Russell, 1993; Côté, Salmela, & Russell, 1995b; Glaser & Strauss, 1967) was used to analyse the observation and interview accounts. This enabled rich descriptions of what effective coaches do as well as providing information regarding how and why they carry out certain actions. Findings from the current research indicated that an effective coach possesses specific personal characteristics, qualities and skills as well as a general philosophy or direction for the team. The effective coach uses their own unique leadership, player management, communication and planning skills to create and maintain the team environment to ensure that everyone involved with the team ‘works off the same page’. The interaction of all these features leads to the primary goal of player development, improvement in player performance and winning matches. This thesis identified key perceptions and applications of effective coaching based on Australian professional coach and player experiences.

Full textBackground: Rugby League is a popular full-contact sport played internationally by 18 full-member test nations of the Rugby League International Federations (RLIF), 21 RLIF affiliate-members, and approximately 32 other unaffiliated nations. The most popular elite, professional, domestic leagues are played in Australia and the United Kingdom. Rugby league game play involves numerous collisions and tackles, and it carries an inherent risk for injury including head trauma. Despite the increased interest in sport-related concussion in recent years, only a limited number of studies have been conducted in rugby league players on this topic, with the large majority of publications only addressing the incidence of concussion as a secondary outcome measure within sports-specific injury focused studies. Additionally, there are currently no published papers on the potential long-term consequences of sport-related concussion in retired professional rugby league players. Aim/Purpose: This thesis addresses some of the issues related to the identification and acute management of sport-related concussion in professional rugby league players. It also examines the potential long-term consequence of concussion in retired professional rugby league players. One of the overall aims of this thesis was to conduct a systematic review of the literature examining both, (i) concussion in rugby league; and (ii) the use of magnetic resonance spectroscopy in sport-related concussion. These systematic review papers set the scene for the main aims of this thesis, which were to address the identified gaps in the literature, first by identifying the factors associated with concussion in rugby league at the professional level via systematic video analysis of the injury. The purpose of this first study was to described player and injury characteristics, situational factors, concussion signs, and return to play. A secondly aim was to examine the potential long-term consequences of a history of multiple concussions in retired professional rugby league players. The purpose of this second study was to examine the brain neurometabolite concentrations and the cognitive profiles of retired rugby league players who had a history of numerous self-reported concussions. Methods: Paper 1: This systematic review involved the retrieval of eligible studies pertaining to concussion in rugby league players. Numerous online databases were searched for publication in English from 1900 up to June 2013 using the key search terms: rugby league, league, football; in combination with injury terms: athletic injuries, concussion, sports concussion, sports related concussion, brain concussion, brain injury, brain injuries, mild traumatic brain injury, mTBI, traumatic brain injury, TBI, craniocerebral trauma, head injury, and brain damage. Articles were regarded as relevant and warranting inclusion if they were experimental studies examining concussed rugby league players. Studies were included whether they were conducted with acute or long-term concussed athletes (i.e., there were no restrictions placed on time elapsed since injury). Paper 2: All National Rugby League clubs were invited to participate in this video analysis study of concussion, three agreed to participate. All players medically diagnosed with a concussion by an experienced team physician from the three participating clubs were included in the study. The digital video footage of games in which each concussion was diagnosed was reviewed. Descriptions pertaining to player’s demographic information (i.e., age, height, weight, playing position, and game performance statistics) and return to match play were also recorded. Two raters independently viewed the digital records of events leading to concussion. Relevant variables were pre-determined and data were independently recorded by both raters. In order to reach consensus, all discrepancies between raters resulted in a review of the footage together and a discussion regarding the recorded data. Under circumstances where consensus was not reached, a third rater was to be consulted to make the final determination, however this was not required. Paper 3: Each use of the ‘Concussion Interchange Rule’ (‘CIR’) during the 2014 National Rugby League season was included in the study. There was no video analysis conducted on any event that was not logged and assessed by club medical staff. Access to video footage of the incident was attained through the National Rugby League’s Digital Press Pass subscription. All uses of the CIR were independently reviewed by the first author and at least one other author. Two authors were blinded to the study hypotheses but the first author was not blinded. The three raters determined whether any of six signs (loss of consciousness, loss of muscle tone, seizures, clutching of the head, unsteadiness of gait, or possible impairment in cognition or awareness as evidenced by a blank or vacant stare) were present, absent, or indeterminable based on the available footage of the incident for every case. When there was disagreement between the two primary raters (who rated all incidents), both raters reviewed and discussed those cases in an effort to reach consensus. In the cases where consensus could not be achieved, ratings from a third rater were used. Paper 4: This systematic review involved the retrieval of eligible studies pertaining to magnetic resonance spectroscopy and concussion in athletes. Numerous online databases were searched for publication in English up to February 2013 using the key search terms: magnetic resonance spectroscopy, nuclear magnetic resonance spectroscopy, neurospectroscopy, spectroscopy, two-dimensional nuclear magnetic resonance spectroscopy, correlation spectroscopy, J-spectroscopy, exchange spectroscopy, nuclear overhauser effect spectroscopy, NMR, MRS, COSY, EXSY, NOESY, 2D NMR, craniocerebral trauma, mild traumatic brain injury, mTBI, traumatic brain injury, brain concussion, concussion, brain damage, sport, athletic, and athlete. Articles were regarded as relevant, and warranting inclusion in the review if they were experimental studies using MRS to determine the presence (or absence) of pathophysiology in concussed athletic samples. Studies were included whether they were conducted acutely or post-acutely (i.e., there were no restrictions placed on time since injury) and whether or not they also used other outcome measures (e.g., conventional MRI, CT, symptom checklists, balance testing, or neuropsychological testing). All retrieved articles were independently assessed for quality using a standardized quality assessment checklist. Paper 5: Retired professional rugby league players (n=13) were recruited through communication with the club alumni. Exclusion criteria included any medical history of neurosurgery, or any history of a brain tumor requiring radiation treatment, or claustrophobia. Healthy community control subjects similar in age and education were recruited through a research participant registry established by a medical research institute. All participants completed a clinical interview and neurocognitive testing. The total interview and testing time was approximately 135 minutes. The MRS data was collected during a separate, single testing session on all participants as one component of a multiparametric neuroimaging study. The imaging time for the MRS component of the study was approximately 25 minutes; the whole multiparametric acquisition time was approximately 65 minutes. An overall test battery mean was computed by summing and averaging the normative scores (expressed in T score units with a mean of 50 and a SD of 10). Conventional Imaging was performed on a 3 T Siemens Skyra scanner with a 20-channel head coil. MRS voxels were placed in posterior cingulate grey matter (GM) and parietal white matter (WM). Concentrations of glutamate (Glu), glutathione (GSH), myo-inositol (mI), N-acetylaspartate (NAA), total choline (tCho), creatine+phosphocreatine (tCr), and glutamate+glutamine (Glx) were quantified using LCModel and water scaling. Results: The systematic review of the rugby league literature identified that very little research had been conducted evaluating concussion. One hundred and ninety nine rugby league injury publications were identified. Thirty-nine (20%) were related in some way to concussion. Of the 39 identified articles, 6 (15%) had the main aim of evaluating concussion, while the other 33 reported on concussion incidence as part of overall injury data analyses. Rugby league concussion incidence rates vary widely from 0.0 to 40.0/1000 playing hours, depending on the definition of concussion injury (game time loss vs. no game time loss). The incidence rates vary across match play versus training session, seasons (winter vs. summer) and playing position (forwards vs. backs). The ball carrier has been found to be at greater risk for injury than tacklers. Concussion accounts for 29% of all injuries associated with illegal play, but only 9% of injuries sustained in legal play. Video analysis of medically diagnosed concussions during the 2013 National Rugby League (NRL) season identified most concussions (83%) occurred during a high tackle, and all concussed ball carriers were hit high. None of the striking players were concussed. All concussions involved a blow to the head or face. Loss of consciousness was observed in 30% of cases. Only half of the total sample was removed from play, and one athlete who was removed returned to play in the same match. Of the players who were removed from play, the large majority returned to play the following week. Illegal play accounted for 25% of all concussions. The concussion incidence was 14.8 injuries per 1,000 player NRL match hours or approximately one concussion every four games. The video analysis of the use of the concussion interchange rule (CIR) during the 2014 season identified 167 uses of the CIR. Loss of consciousness was observed in 30.2% of cases. Common observable signs of injury included clutching the head (69.1%), loss of muscle tone (50.0%), unsteadiness of gait (52.5%), and a blank or vacant state (59.9%). Concussive convulsions were observed in 1.9%. The overall inter-rater reliability for these concussion signs for the two raters was κ = 0.60 (95% CI = 0.56-0.64), which is considered to be weak to moderate agreement. More than half of the players who used the CIR returned to play later in the same match (56.8%). Of the players who used the CIR, and who had three or more observable signs of possible injury, 46.4% returned to play in the same game. No player used the CIR more than once in the same game. Of the players who were removed from play, the large majority returned the following week. Forwards (69.9%) used the CIR significantly more often than backs (30.1%). Most incidences occurred from a hit up (62.3%) and occurred during a high tackle (80%). The incidence rate was 24.03 uses of the CIR per 1,000 NRL player match hours. This equates to approximately one CIR every 2.41 games in the 2014 NRL season. The systematic review of magnetic resonance spectroscopy (MRS) in sport-related concussion identified only eleven publications, with varying methodology and results. The review identified 11 publications that met criteria for inclusion, comprised of data on 200 athletes and 116 controls. Nine of 11 studies reported a MRS abnormality consistent with an alteration in neurochemistry. The results support the use of MRS as a research tool for identifying altered neurophysiology and monitoring recovery in adult athletes, even beyond the resolution of post-concussive symptoms and other investigation techniques returning to normative levels. In new data collected as part of the thesis, the MRS profiles of retired NRL players differed compared to community age- and education-matched control participants. From a clinical perspective, these early middle-aged retired athletes did not report more depression, anxiety, or stress, and they did not have worse cognitive functioning, than control subjects (although one retired player met clinical criteria for mild cognitive impairment [MCI]). They did, however, perform more poorly than controls on non-dominant fine motor coordination and speed, and their balance scores were correlated with lower levels of some neurometabolites. A significant difference between groups was observed in grey matter N-acetylaspartate (NAA), with significantly lower concentrations of NAA found in retired athletes. No significant differences were found in white matter NAA. Secondary analysis found a significant difference between groups in grey matter myo-inositol (mI), with retired players having lower concentrations compared to controls. There was a significant difference in grey matter glutathione, with retired players showing lower concentrations compared to controls. There were no significant difference between groups in grey matter choline or glutamate concentrations. In white matter, there were no statistically significant differences in any of the neurometabolites that were hypothesized to differ (mI, choline, glutamate, or glutathione). Conclusion: Rugby league is a contact sport with high incidence of concussions, which leads to participants being exposed to numerous concussions during their careers. The current series of studies adds enormously to rugby league concussion literature, which had previously been quite limited, as identified in the systematic review of the rugby league concussion literature (Chapter 2). The current series of studies characterised concussion at the professional level in current rugby league players; identifying antecedent events and risk factors, together with return to play management and decision-making. In addition to investigating current players, this series of studies also investigated cognition and neurometabolites in retired professional rugby league players. While the current series of studies identifies concussion as a common risk factor for participation in rugby league, the potential long-term consequences for rugby league players with a history of numerous concussions remains a topic requiring further investigation. In the small sample of retired players included in Study 3, not one player expressed significant concerns regarding their cognition and on neuropsychological assessment none of the retired rugby league players performed significantly below their estimated pre-morbid level of intellectual function. So for all intents and purposes the investigation was conducted in ‘asymptomatic’ retired rugby league players, however there were significant neurometabolic differences observed between groups on magnetic resonance spectroscopy. The clinical relevance of this finding also requires further investigation, but it may suggest that MRS is sensitive to possible pre-clinical symptomology that other methodologies (i.e., neuropsychological testing) are not sufficiently sensitive to detect.

Full textSport as a whole has recently been under greater scrutiny over the safety of its participants. The tragic death of Australian Test Cricketer Philip Hughes brought into stark focus the risk of head injury but there has also been greater awareness of hypertrophic cardiomyopathy, concussion and use of performance enhancing drugs. Much of the research around concussion arises from what could be described as “collision” sports such as American football and ice hockey. The catalyst for discussions around concussion has tended to originate from these American sport. The significance of this increased awareness of safety has not been lost on the sport of rugby which has caused changes in practice in terms of concussion management but what appears not to have been fully appreciated is the additional risk of cervical spine injury associated with the sport.

Full textThis thesis was concerned with diversity management in professional rugby league football in Australia. It examined the workplace perceptions and expectations of two groups: Pasifika (Pacific Islander and Māori) employees and their non-Pasifika employers in the National Rugby League (NRL), the premier rugby competition in Australasia. The study sought to explore whether Pasifika workplace perceptions, expectations, and contributions aligned with diversity management practices in the NRL. The study adopted an interdisciplinary approach that incorporated both Pacific Studies and diversity management. It drew upon psychological contract (PC) theory in order to understand workplace experiences. These were explored via a culturally appropriate 𝘵𝘢𝘭𝘢𝘯𝘰𝘢 approach to interpersonal dialogue, this involving exchange of conversations, stories and ideas with 40 relevant individuals in the NRL. The findings revealed that Pasifika employees in the NRL place greater emphasis on 𝘳𝘦𝘭𝘢𝘵𝘪𝘰𝘯𝘢𝘭 aspects of the exchange relationship, specifically drawing upon familial motivations, cultural values and customs, as well as community service and spirituality. The study was able to contribute to sport management scholarship in two key ways. First, by advancing qualitative research into Pasifika workplace experiences – both on and off the field – in elite rugby league. Second, the thesis broadened the scope of psychological contract research to encompass diversity management considerations – in this case by generating knowledge about how Pasifika employees navigate Western workplaces.

Full textBackground: The importance of optimal and/or superior vision for participation in high-level sport remains the subject of considerable clinical research interest. Here we examine the vision and visual history of elite/near-elite cricketers and rugby-league players. Methods: Stereoacuity (TNO), colour vision, and distance (with/without pinhole) and near visual acuity (VA) were measured in two cricket squads (elite/international-level, female, n=16; near-elite, male, n=23) and one professional rugby-league squad (male, n=20). Refractive error was determined, and details of any correction worn and visual history were recorded. Results: Overall, 63% had their last eye-examination within 2 years. However, some had not had an eye examination for 5 years, or had never had one (near-elite-cricketers: 30%; rugby-league players: 15%; elite-cricketers: 6%). Comparing our results for all participants to published data for young, optimally-corrected, non-sporting adults, distance VA was ~1 line of letters worse than expected. Adopting α=0.01, the deficit in distance-VA deficit was significant, but only for elite-cricketers (p<0.001) (near-elite cricketers, p=0.02; rugby-league players, p=0.03). Near-VA did not differ between subgroups or relative to published norms for young adults (p>0.02 for all comparisons). On average, stereoacuity was better than in young adults, but only in elite-cricketers (p<0.001; p=0.03, near-elite-cricketers; p=0.47, rugby-league -players). On-field visual issues were present in 27% of participants, and mostly (in 75% of cases) comprised uncorrected ametropia. Some cricketers (near-elite: 17.4%; elite: 38%) wore refractive correction during play but no rugby-league player did. Some individuals with prescribed correction choose not to wear it when playing. Conclusion: Aside from near stereoacuity in elite-cricketers, these basic visual abilities were not better than equivalent, published data for optimally-corrected adults. 20-25% exhibited sub-optimal vision, suggesting that the clearest possible vision might not be critical for participation at the highest levels in the sports of cricket or rugby-league. Although vision could be improved in a sizeable proportion of our sample, the impact of correcting these, mostly subtle, refractive anomalies on playing performance is unknown.

Full textBackground: Rugby league is a full-contact collision sport that carries a high risk of sport-related concussion. There are few studies in rugby league that utilise video analysis and wearable head impact sensor data together to investigate head impact exposures across a full season. Purpose: To verify wearable head impact sensor data using video analysis and describe game-play characteristics and head biomechanics that contribute to concussion in rugby league. Methods: The x-PatchTM was used for a season of men’s semi-professional and junior boys representative level rugby league. A total of twenty-nine players were monitored and game-day footage by a trained videographer was recorded and analysed to verify head impacts and describe impact rates, playing and gameplay characteristics of video-verified head impacts. Results: The x-PatchTM recorded a total of 1,403 impacts 20g between game start and finish across the two studies in this thesis, of which 1,296 (92%) were verified on video. In study ,1 the number of video-verified impacts 20g, per playing hour, was 7.8 for forwards and 4.8 for backs. Impacts resulting in concussion had a much greater peak linear acceleration (M = 76.1g, SD = 17.0) than impacts that did not result in concussion (M = 34.2g, SD = 18.0; Cohen’s d = 2.4). Study 2 found 73.2% of all verified impacts 20g where determined to be direct head impacts and occurred at a rate of 5.2 impacts per game hour. Conclusion: There were high rates of agreement between video-verified and sensor recorded game play impacts 20g and also a number of triggered events that occurred during gameplay that did not correlate with an impact on video review. The use of a secondary source, such as video review, to verify x-PatchTM recorded impacts is extremely important when analysing total head impact exposure as failure to remove ‘false-positive’ impacts may inflate player’s cumulative and average head impact exposures.

Full textIntroduction Forty-six elite adolescent male rugby league players (12-17 years) participated in a nine-week study to determine the effects of three exercise training programs on 0-30 metres sprint running time and bounds performance (10 bounds). Subjects were randomly assigned to a rugby league fitness group (F) n=12, a sprint group (S) n= 14 and a sprint-bounds group (SB) n= 20. Forty-two subjects completed the study. Methods: Separate sessions for fitness, speed, and bounds were conducted once a week for nine weeks. To determine the effect of training a two-way analysis of variance was performed, followed by post-hoc paired t-tests to allow pairwise comparisons when significant interactions were found. Significance was set at p<0.05. Statistical analysis was performed using SPSS for Mac (version 13.1). Effect sizes were calculated to evaluate the meaningfulness of observed changes. Results: Moderate improvements (p<0.05; 5%) were observed in both the F and SB groups over 10 m. Speed changes over 30 m differed more among the groups. The F group recorded moderate (p<0.01; 4%) improvements, small improvements (p<0.01; 3%) in the SB group and trivial difference (p<0.05) in the S group. The F and S groups improved by approximately 7% (p<0.01) in bounds performance over 10 bounds whereas the SB group improved by approximately 10% (p<0.01) in bounds performance over 10 bounds. Group S had faster sprint times (p<0.05) prior to training compared to groups F and SB. Discussion: All three programs led to improvements in sprint speed and bounds distance, but the extent of the improvements varied with the specificity of the training program and pre-training performance level. Groups F and SB had 4-5% improvements in sprint speed over 30 m whereas group S showed relatively trivial changes. In all groups, the improvements were greater over 10 m and least over 30 m. Bounds distance improved more than sprint speed, and the greatest improvement was achieved in the SB group compared to the F and S groups. Conclusion: Rugby league training (game specific drills and extended efforts) coupled with the various components of physical activity can improve speed and power as effectively as specific speed and power training in adolescent boys. Training for acceleration can selectively improve 0-10 m speed more than 0-30 m speed. Sprint and bounds training have been shown to be safe and effective methods to increase speed and power in this group of adolescents.
