Maximum running intensities during English academy rugby union match-play

ABSTRACTTo quantify and compare the maximum running intensities during rugby union match-play.Running intensity was quantified using micro-technology devices (S5 Optimeye, Catapult) from 202 players during 24 matches (472 observations). Instantaneous speed was used to calculate relative distance (m·min−1) using a 0.1 s rolling mean for different time durations (15 and 30 s and 1, 2, 2.5, 3, 4, 5, and 10 min). Data were analysed using a linear mixed-model and assessed with magnitude-based inferences and effect sizes (ES).Running intensity for consecutive durations (e.g., 15 s vs. 30 s, 30 s vs. 1 min, etc.) decreased as time increased (ES = 0.48–2.80). Running intensity was lower in forwards than backs during all durations (−0.74 ±0.21 to −1.19 ±0.21). Running intensity for the second row and back row positions was greater than the front row players at all durations (−0.58 ±0.38 to −1.18 ±0.29). Running intensity for scrum halves was greater (0.46 ±0.43 to 0.86 ±0.39) than inside and outside backs for all durations besides 15 and 30 s.Front rowers and scrum halves were markedly different from other sub-positional groups and should be conditioned appropriately. Coaches working in academy rugby can use this information to appropriately overload the intensity of running, specific to time durations and positions.

The organised chaos of English adolescent rugby union: Influence of weekly match frequency on the variability of match and training loads

The aims of this study were to determine the variability of weekly match and training loads in adolescent rugby union players across a competitive season, and to investigate the effect of match frequency on load distribution across different activities. Internal match and training load data (i.e. session-rating of perceived exertion (sRPE)) were collected daily from 20 players from a regional academy across a 14-week season. Data were analysed using a mixed-effects linear model, and variability was reported as a coefficient of variation (CV). Differences between 0-, 1-, 2-, and 3-match weeks were assessed using Cohen’s d effect sizes and magnitude-based inferences. Mean weekly total match and training sRPE load was 1425 ± 545 arbitrary units (AU), with a between-player CV of 10 ± 6% and within-player CV of 37 ± 3%. Mean week-to-week change in total sRPE load was 497 ± 423 AU (35%), and 40% of weekly observations were outside the suggested acute:chronic workload ratio ‘safe zone’. Total weekly sRPE loads increased substantially with match frequency (1210 ± 571, 1511 ± 489, and 1692 ± 517 AU, for 0-, 1-, and 2-match weeks, respectively), except for 3-match weeks (1520 ± 442 AU). Weekly match and training loads were highly variable for adolescent rugby players during the competitive season, and match frequency has a substantial effect on the distribution of loads. Therefore, match and training loads should be coordinated, monitored, and managed on an individual basis to protect players from negative training consequences, and to promote long-term athlete development.

An Explorative Investigation of Referee Abuse in English Rugby League

This article explored the experiences of 89 rugby league referees in England who undertook a mixed methods online survey from the January 9 to March 31, 2017. The results of the survey produced rich data from the open responses, and the quantitative measures are used to support these open responses. Findings identified an established culture of abuse towards referees, a refereeing workforce requiring greater support, better communication with the governing body and, therefore, revisions to existing policy and training. Conclusions identified specific recommendations and policy implications to improve the operational environment and working conditions and increased support for referees. Subscribe to JASM

A Kinetic Model Describing Injury-Burden in Team Sports

Injuries in team sports are normally characterised by the incidence, severity, and location and type of injuries sustained: these measures, however, do not provide an insight into the variable injury-burden experienced during a season. Injury burden varies according to the team's match and training loads, the rate at which injuries are sustained and the time taken for these injuries to resolve. At the present time, this time-based variation of injury burden has not been modelled. To develop a kinetic model describing the time-based injury burden experienced by teams in elite team sports and to demonstrate the model's utility. Rates of injury were quantified using a large eight-season database of rugby injuries (5253) and exposure (60,085 player-match-hours) in English professional rugby. Rates of recovery from injury were quantified using time-to-recovery analysis of the injuries. The kinetic model proposed for predicting a team's time-based injury burden is based on a composite rate equation developed from the incidence of injury, a first-order rate of recovery from injury and the team's playing load. The utility of the model was demonstrated by examining common scenarios encountered in elite rugby. The kinetic model developed describes and predicts the variable injury-burden arising from match play during a season of rugby union based on the incidence of match injuries, the rate of recovery from injury and the playing load. The model is equally applicable to other team sports and other scenarios.

English doping suspension trigger event for U.S. news

This study examined the extent to which a “trigger event” in European sports altered coverage of doping in United States newspapers. Specifically, the study analyzed references to human growth hormone (hGH) before and after English rugby player Terry Newton became the first athlete to test positive for hGH. The research observed increases in hGH references following an announcement that Newton had tested positive and would receive a two-year ban from competition.

Different shaped ball, same financial problems? A holistic performance assessment of English Rugby Union (2006-2015)

PurposeRugby union’s late move to professionalism in 1995 has led to concerns about the financial development of the game. The purpose of this paper is to extend the knowledge base on professional team sports in the UK by analysing the financial and sporting performance of rugby union clubs.Design/methodology/approachData were obtained by dissecting the annual accounts of nine English Premiership rugby clubs between 2006 and 2015. Analysis was performed using the performance assessment model, which analyses both financial and sporting areas of performance and is devised through statistical analysis procedures to provide a holistic measure of overall performance for each club.FindingsThere is financial disparity amongst clubs that has widened over the period of the study. In terms of sporting performance, the data suggest that competition is more equal, something that is less evident in other UK professional team sports such as football and rugby league. Correlation analysis reveals that overall performance varies over time in cycles.Research limitations/implicationsThe study has implications for the clubs competing in the English Premiership and for the league organisers themselves, particularly with reference to regulatory procedures such as raising the salary cap and increased broadcasting deals.Originality/valueThe paper has demonstrated the importance of balancing multiple performance objectives in professional team sports and has expanded the academic discussion on the financial health of professional team sports in the UK, particularly with reference to the financial health of rugby union where research has historically been scarce.

EPIDEMIOLOGY OF INJURIES IN ENGLISH COMMUNITY LEVEL RUGBY UNION USING SMS PLAYER SELF-REPORTED DATA

BackgroundThe reporting of non-time loss injuries in community sport can be challenging due to infrequent contact between players and team medical staff. Text messaging or short messaging service (SMS) is...

Concussions and Head Injuries in English Community Rugby Union Match Play

Background: Previous research has described general injury patterns in community-level rugby union, but specific information on time-loss head injuries has not been reported. Purpose: To establish the incidence and nature of significant time-loss head injuries in English community rugby match play, and to identify the injury risk for specific contact events. Study Design: Descriptive epidemiology study. Methods: Over 6 seasons, injury information was collected from 46 (2009-2010), 67 (2010-2011), 76 (2011-2012), 50 (2012-2013), 67 (2013-2014), and 58 (2014-2015) English community rugby clubs (Rugby Football Union levels 3-9) over a total of 175,940 hours of player match exposure. Club injury management staff reported information for all head injuries sustained during match play whereby the player was absent for 8 days or greater. Clubs were subdivided into semiprofessional (mean player age, 24.6 ± 4.7 years), amateur (24.9 ± 5.1 years), and recreational (25.6 ± 6.1 years) playing levels. Contact events from a sample of 30 matches filmed over seasons 2009-2010, 2010-2011, and 2011-2012 provided mean values for the frequency of contact events. Results: The overall incidence for time-loss head injuries was 2.43 injuries per 1000 player match hours, with a higher incidence for the amateur (2.78; 95% CI, 2.37-3.20) compared with recreational (2.20; 95% CI, 1.86-2.53) (P = .032) playing level but not different to the semiprofessional (2.31; 95% CI, 1.83-2.79) playing level. Concussion was the most common time-loss head injury, with 1.46 per 1000 player match hours. The tackle event was associated with 64% of all head injuries and 74% of all concussions. There was also a higher risk of injuries per tackle (0.33 per 1000 events; 95% CI, 0.30-0.37) compared with all other contact events. Conclusion: Concussion was the most common head injury diagnosis, although it is likely that this injury was underreported. Continuing education programs for medical staff and players are essential for the improved identification and management of these injuries. With the majority of head injuries occurring during a tackle, an improved technique in this contact event through coach and player education may be effective in reducing these injuries.

Dietary Intakes of Elite 14- to 19-Year-Old English Academy Rugby Players During a Pre-Season Training Period

Good nutrition is essential for the physical development of adolescent athletes, however data on dietary intakes of adolescent rugby players are lacking. This study quantified and evaluated dietary intake in 87 elite male English academy rugby league (RL) and rugby union (RU) players by age (under 16 (U16) and under 19 (U19) years old) and code (RL and RU). Relationships of intakes with body mass and composition (sum of 8 skinfolds) were also investigated. Using 4-day diet and physical activity diaries, dietary intake was compared with adolescent sports nutrition recommendations and the UK national food guide. Dietary intake did not differ by code, whereas U19s consumed greater energy (3366 ± 658 vs. 2995 ± 774 kcal·day-1), protein (207 ± 49 vs. 150 ± 53 g·day-1) and fluid (4221 ± 1323 vs. 3137 ± 1015 ml·day-1) than U16s. U19s consumed a better quality diet than U16s (greater intakes of fruit and vegetables; 4.4 ± 1.9 vs. 2.8 ± 1.5 servings·day-1; nondairy proteins; 3.9 ± 1.1 vs. 2.9 ± 1.1 servings·day-1) and less fats and sugars (2.0 ± 1. vs. 3.6 ± 2.1 servings·day-1). Protein intake vs. body mass was moderate (r = .46, p < .001), and other relationships were weak. The findings of this study suggest adolescent rugby players consume adequate dietary intakes in relation to current guidelines for energy, macronutrient and fluid intake. Players should improve the quality of their diet by replacing intakes from the fats and sugars food group with healthier choices, while maintaining current energy, and macronutrient intakes.

The Comparison Of Competitive Balance Between Super Rugby (Sanzar) And English Premiership Rugby: A Case Study From 1996-2014 Season Or Not Attractive – No People – No Money

Most sports are attractive because they are almost unpredictable. The more the competitiveness of league teams, the harder to predict the games and as a result, that league will be more attractive. Message is: more attractive leagues= bigger audience= more attractive for sponsorship= more money in sport. Competitive balance (CB) refers to the balance in sport capabilities of teams. The aim of this paper was to compare the competitive balance between Super Rugby league named SANZAR, which consist of three nations (New Zealand, Australia and South Africa) and English Premiership Rugby League in 1996-2014 seasons and compare them. The data were secondary and collected from the final tables. It was used five models in this study: the three-club and five-club concentration ratio (C3 and C5) and C3/C5 index of competitive balance (C3ICB/C5ICB) were used to analyse the data. The less the index C3ICB/C5ICB and C3/C5 are, the more competitive balance is, and conversely. Standard deviation of game results, the ratio of actual and ideal standard deviation wins, numbers of winners and a placement in the k-th place. The results showed that the Salary cap in Premiership League does not work very effectively and the competitive balance is in last few seasons still worst and worst. Super Rugby has mirror position to Premiership. Last few years are the competitive balance on the right track. Comparison result is for Super Rugby strategy with involving more teams to the league.

Egg-shell skulls or institutional negligence? The liability of World Rugby for incidents of concussion suffered by professional players in England and Ireland

The number of incidents of concussion in professional rugby union is increasing steadily. In the English Rugby Premiership, concussion was the most frequent injury suffered by professional players in each of the last 3 seasons. Further, there is developing evidence of a link between suffering repeated concussions and chronic traumatic encephalopathy, a degenerative brain disease. World Rugby’s principal response to the growing problem of concussion in rugby has been through the introduction of the Pitch Side Concussion Assessment and the Return to Play protocols. Few amendments have been made to the playing rules of the sport with the express intention of reducing the frequency with which concussions occur. The article explores whether World Rugby could be found to owe professional rugby players a duty of care under the laws of negligence in England and Ireland. The article then goes on to examine if World Rugby could be found to have acted negligently in its response to the issue of concussion, through the adoption of its concussion management rules and its failure to amend the playing rules of the sport in an attempt to prevent concussions from occurring. Following this, the article analyses the difficulty which a potential plaintiff would face in establishing causation in a negligence action against World Rugby. The article concludes with suggested changes which World Rugby could implement to lessen the possibility of a finding that it has acted negligently in relation to players’ safety.

Anthropometric, Sprint, and High-Intensity Running Profiles of English Academy Rugby Union Players by Position.

The purpose of this study was to evaluate the anthropometric, sprint, and high-intensity running profiles of English academy rugby union players by playing positions, and to investigate the relationships between anthropometric, sprint, and high-intensity running characteristics. Data were collected from 67 academy players after the off-season period and consisted of anthropometric (height, body mass, sum of 8 skinfolds [∑SF]), 40-m linear sprint (5-, 10-, 20-, and 40-m splits), the Yo-Yo intermittent recovery test level 1 (Yo-Yo IRTL-1), and the 30-15 intermittent fitness test (30-15 IFT). Forwards displayed greater stature, body mass, and ∑SF; sprint times and sprint momentum, with lower high-intensity running ability and sprint velocities than backs. Comparisons between age categories demonstrated body mass and sprint momentum to have the largest differences at consecutive age categories for forwards and backs; whereas 20-40-m sprint velocity was discriminate for forwards between under 16s, 18s, and 21s. Relationships between anthropometric, sprint velocity, momentum, and high-intensity running ability demonstrated body mass to negatively impact on sprint velocity (10 m; r = -0.34 to -0.46) and positively affect sprint momentum (e.g., 5 m; r = 0.85-0.93), with large to very large negative relationships with the Yo-Yo IRTL-1 (r = -0.65 to -0.74) and 30-15 IFT (r = -0.59 to -0.79). These findings suggest that there are distinct anthropometric, sprint, and high-intensity running ability differences between and within positions in junior rugby union players. The development of sprint and high-intensity running ability may be impacted by continued increases in body mass as there seems to be a trade-off between momentum, velocity, and the ability to complete high-intensity running.

Physical Qualities of International Female Rugby League Players by Playing Position.

The purpose of this study was to investigate the anthropometric, body composition, and fitness characteristics of female rugby league players by playing position. Data were collected on 27 players who were part of the English elite women's rugby league squad. Player assessments comprised anthropometric (stature and body mass), body composition (dual-energy X-ray absorptiometry) and fitness {lower-body power (countermovement jump [CMJ], 20 kg jump squat [JS], and 30 cm drop jump), 5, 10, 20, 30, and 40 m sprint, 505 agility, Yo-Yo intermittent recovery test level 1} measures. Players were classified into playing position (i.e., forwards and backs) before analysis. A multivariate analysis of variance demonstrated significant (p ≤ 0.05) differences for body mass, stature, total fat, lean mass, and percentage body fat between forwards and backs. Positional differences were also observed for speed, agility, and lower-body power. Significant relationships were observed between total body fat and all fitness variables, and total lean mass was related to CMJ and JS peak power. This study provides comparative data for female rugby league forwards and backs. Body fat was strongly associated with performance and should therefore be considered in developing fitness characteristics. The relationship to match performance and trainability of these characteristics warrants further investigation.

Can practice make perfect? Security and the 2010 FIFA World Cup

The security of major events such as the FIFA Confederations Cup (FCC) in 2009 and the FIFA World Cup (FWC) in 2010 is crucial to their success. This article explores South Africa's readiness for the FWC from a security perspective, and considers the security machinery responsible for the planning of the operation and its eventual implementation. It also provides a synopsis of other security operations during 2009, such as the general elections, the Indian Premier League Cricket tournament and the British and Irish Lions rugby tour, and the lessons learnt from these. In addition, policing the wave of service delivery protests and strikes during the first half of 2009 added valuable lessons, especially in relation to crowd management. Finally, the article considers some of the real and potential security threats for the FWC and concludes that, in spite of a few remaining concerns, South Africa has the will and capacity to provide high quality security for one of the world's biggest sporting events.

Nutritional knowledge and eating habits of professional rugby league players: does knowledge translate into practice?

BackgroundAdequate nutrient intake is important to support training and to optimise performance of elite athletes. Nutritional knowledge has been shown to play an important role in adopting optimal nutrition practices. The aim of the present study was to investigate the relationship between the level of nutritional knowledge and dietary habits in elite English rugby league players using the eatwell plate food categories.MethodGeneral nutritional knowledge questionnaires were collected during the Super League competitive season in the first team squad of 21 professional Rugby league players (mean age 25 ± 5 yrs, BMI 27 ± 2.4 kg/m2, experience in game 6 ± 4 yrs). According to their nutritional knowledge scores, the players were assigned to either good or poor nutritional knowledge group (n = 11, n = 10, respectively). Their dietary habits were assessment using a food frequency questionnaire.ResultsThe findings revealed that nutritional knowledge was adequate (mean 72.82%) in this group of athletes with the highest scores in dietary advice section (85.71%), followed by food groups (71.24%) and food choice (69.52%). The majority of athletes were not aware of current carbohydrate recommendations. This translated into their dietary habits as many starchy and fibrous foods were consumed only occasionally by poor nutritional knowledge group. In terms of their eating habits, the good nutritional knowledge group consumed significantly more fruit and vegetables, and starchy foods (p <.05). Nutritional knowledge was positively correlated to fruit and vegetables consumption (rs = .52, p <.05) but not to any other eatwell plate categories.ConclusionsThe study identified adequate general nutritional knowledge in professional rugby league players with the exception of recommendation for starchy and fibrous foods. Players who scored higher in nutritional knowledge test were more likely to consume more fruits, vegetables and carbohydrate-rich foods.

Psychobehaviorally Based Features of Effective Talent Development in Rugby Union: A Coach’s Perspective

Talent development (TD) is widely recognized as a nonlinear and dynamic process, with psychology a key determinant of long-term success in sport. However, given the role that positive characteristics play in the TD process, there is a relative dearth of research examining the psychological characteristics that may derail development. A retrospective qualitative investigation was conducted with academy coaches and directors within rugby union (n = 15), representing nine different elite English rugby union academies, to identify both positive and negative issues that influenced TD. Comprehensive support was found for existing positive constructs as facilitators of effective development. A range of inappropriately applied ‘positive’ characteristics were identified as having a negative impact on development. Potential clinical issues were also recognized by coaches as talent derailers. It is proposed that by incorporating these potentially negative factors into existing formative assessment tools, a more effective development process can be achieved.

Strength and Power Development in Professional Rugby Union Players Over a Training and Playing Season.

To investigate strength and power development in elite rugby players during the different phases of a professional season. Sixteen professional rugby union athletes from an English premiership team were monitored for measures of lower-body peak force, force at 50 ms, force at 100 ms (all isometric squat), and power (explosive hack squat). Athletes were assessed at the start of preseason (T1), postpreseason (T2), midway through the competitive season (T3), and at the end of the competitive season (T4). Effect-size (ES) statistics with magnitude-based inferences were calculated to interpret differences in physical performance between the different stages of the season. Very likely beneficial increases in force at 50 ms (+16%, ES = 0.75 ± 0.4) and 100 ms (+14%, ES = 0.63 ± 0.4) were observed between T1 and T2. A likely beneficial increase in power was observed between T2 and T3 (+4%, ES = 0.31 ± 0.2). Between T3 and T4, decreases in force at 50 ms (-6%, ES = -0.39 ± 0.3) and 100 ms (-9%, ES = -0.52 ± 0.4) occurred, while peak force and power were maintained. Over the full season (T1-T4) clear beneficial increases in all measures of strength and power were identified. Meaningful increases in strength and power can be achieved in professional English premiership rugby players over a full playing season. The greatest opportunity for strength and power development occurs during pre- to midseason phases, while these measures are maintained or decrease slightly during the latter stages of a season.

Anthropometric and Physical Profiles of English Academy Rugby Union Players.

The purpose of this study was to evaluate the anthropometric and physical characteristics of English regional academy rugby union players by age category (under 16s, under 18s and under 21s). Data were collected on 67 academy players at the beginning of the preseason period and comprised anthropometric (height, body mass, and sum of 8 skinfolds) and physical (5-, 10-, 20-, and 40-m sprint, acceleration, velocity, and momentum; agility 505; vertical jump; Yo-Yo intermittent recovery test level 1; 30-15 intermittent fitness test; absolute and relative 3 repetition maximum front squat, split squat, bench press, prone row, and chin; and isometric mid-thigh pull). One-way analysis of variance demonstrated significant increases across the 3 age categories (p ≤ 0.05) for height (e.g., 16s = 178.8 ± 7.1; 18s = 183.5 ± 7.2; 21s = 186.7 ± 6.61 cm), body mass (e.g., 16s = 79.4 ± 12.8; 18s = 88.3 ± 11.9; 21s = 98.3 ± 10.4 kg), countermovement jump height and peak power, sprint momentum, velocity, and acceleration; absolute, relative, and isometric (e.g., 16s = 2,157.9 ± 309.9; 18s = 2,561.3 ± 339.4; 21s = 3,104.5 ± 354.0 N) strength. Momentum, maximal speed, and the ability to maintain acceleration were all discriminating factors between age categories, suggesting that these variables may be more important to monitor rather than sprint times. These findings highlight that anthropometric and physical characteristics develop across age categories and provide comparative data for English Academy Rugby Union players.

The motivation behind unsanctioned violence in international rugby: A case study of a former elite player

At focus in this case study was the participant's perception of, and personal involvement in, rugby violence. The participant was a 50-year-old ex-international and former British and Irish Lions rugby union player. A qualitative approach informed by reversal theory and incorporating retrospective semi-structured interview procedures with inductive and deductive elements was used to explore a number of topics related to his rugby playing career, including rugby violence. Among other statements related to play and power violence, the participant described his experience of three major incidents involving personal rugby violence. Each incident resulted in injury to the opposing player which required extensive medical attention. Two of the reported incidents supported previous reversal theory-based research findings related to the motivation behind anger violence in sport. The third incident illustrated a type of sport violence not previously identified in reversal theory-based sport research. It was termed “protective” or “supportive” violence, where an athlete comes to the aid, rescue or defence of a teammate. The findings provide valuable new insights on rugby violence, adding to sport psychology's understanding of the motivational processes involved.

Dehydration and hyponatremia in professional rugby union players: a cohort study observing english premiership rugby union players during match play, field, and gym training in cool environmental conditions.

Fluid and sodium balance is important for performance and health; however, limited data in rugby union players exist. The purpose of the study was to evaluate body mass (BM) change (dehydration) and blood[Na] change during exercise. Data were collected from 10 premiership rugby union players, over a 4-week period. Observations included match play (23 subject observations), field (45 subject observations), and gym (33 subject observations) training sessions. Arrival urine samples were analyzed for osmolality, and samples during exercise were analyzed for [Na]. Body mass and blood[Na] were determined pre- and postexercise. Sweat[Na] was analyzed from sweat patches worn during exercise, and fluid intake was measured during exercise. Calculations of fluid and Na loss were made. Mean arrival urine osmolality was 423 ± 157 mOsm·kg, suggesting players were adequately hydrated. After match play, field, and gym training, BM loss was 1.0 ± 0.7, 0.3 ± 0.6, and 0.1 ± 0.6%, respectively. Fluid loss was significantly greater during match play (1.404 ± 0.977 kg) than field (1.008 ± 0.447 kg, p = 0.021) and gym training (0.639 ± 0.536 kg, p < 0.001). Fluid intake was 0.955 ± 0.562, 1.224 ± 0.601, and 0.987 ± 0.503 kg during match play, field, and gym training, respectively. On 43% of observations, players were hyponatremic when BM increased, 57% when BM was maintained, and 35% when there was a BM loss of 0.1-0.9%. Blood[Na] was the representative of normonatremia when BM loss was >1.0%. The findings demonstrate that rugby union players are adequately hydrated on arrival, fluid intake is excessive compared with fluid loss, and some players are at risk of developing hyponatremia.
