Purpose:To quantify the duration and position-specific peak running intensities of international rugby union for the prescription and monitoring of specific training methodologies.Methods:Global positioning systems (GPS) were used to assess the activity profile of 67 elite-level rugby union players from 2 nations across 33 international matches. A moving-average approach was used to identify the peak relative distance (m/min), average acceleration/deceleration (AveAcc; m/s2), and average metabolic power (Pmet) for a range of durations (1–10 min). Differences between positions and durations were described using a magnitude-based network.Results:Peak running intensity increased as the length of the moving average decreased. There were likely small to moderate increases in relative distance and AveAcc for outside backs, halfbacks, and loose forwards compared with the tight 5 group across all moving-average durations (effect size [ES] = 0.27–1.00). Pmet demands were at least likely greater for outside backs and halfbacks than for the tight 5 (ES = 0.86–0.99). Halfbacks demonstrated the greatest relative distance and Pmet outputs but were similar to outside backs and loose forwards in AveAcc demands.Conclusions:The current study has presented a framework to describe the peak running intensities achieved during international rugby competition by position, which are considerably higher than previously reported whole-period averages. These data provide further knowledge of the peak activity profiles of international rugby competition, and this information can be used to assist coaches and practitioners in adequately preparing athletes for the most demanding periods of play.

Purpose:Investigating adolescent training loads might help us understand optimal training adaptations. GPS tracking devices and training diaries were used to quantify weekly sport and other physical activity demands placed on adolescent rugby union players and profile typical rugby training sessions.Methods:Participants were 75 males age 14 to 18 y who were recruited from rugby teams representing 3 levels of participation: schoolboy, national representative, and a selective sports school talent squad.Results:Schoolboy players covered a distance of (mean ± SD) 3511 ± 836 m, representative-squad players 3576 ± 956 m, and talent-squad players 2208 ± 637 m per rugby training session. The representative squad recorded the highest weekly duration of sport and physical activity (515 ± 222 min/wk), followed by the talent squad (421 ± 211 min/week) and schoolboy group (370 ± 135 min/wk). Profiles of individual players identified as group outliers showed participation in up to 3 games and up to 11 training sessions per week, with twice the weekly load of the team averages.Conclusion:Optimal participation and performance of adolescent rugby union players might be compromised by many high-load, high-impact training sessions and games and commitments to other sports and physical activities. An improved understanding of monitoring and quantifying load in adolescent athletes is needed to facilitate best-practice advice for player management and training prescription.

A training monitoring system (TMS) should be both attainable and scientifically grounded; however, the optimal method of monitoring training is not yet fully understood. The purpose of this study was to develop and evaluate an online TMS for amateur rugby union. The experimental approach to the problem consisted of five phases: (1) establishing the current training and training load (TL) monitoring practices of amateur rugby union teams, (2) designing and developing the TMS, (3) recruiting teams and subsequently introducing the TMS, (4) supporting the strength and conditioning (S&C) coaches using the TMS, and (5) evaluating the TMS. The findings of this study support the use of an online TMS as a useful and effective method of facilitating training prescription and design in an effort to reduce injury risk and enhance performance. The main barriers impeding player compliance are the lack of feedback on their data and evidence of its use in training design, coaching, and prescription. The effectiveness of the system is dependent on the extent to which the associated challenges are mitigated to ensure quality and consistent data. However, this study offers a method of monitoring training that can be effective while also establishing pitfalls to avoid for both practitioners and researchers alike.

Context Individual and team injury burden and performance are 2 key considerations facing practitioners in the daily prescription of an athlete's training load. Whereas a considerable number of researchers have examined univariate relationships between training load and performance, training load and injury, or injury and performance, few investigators have examined all 3 concurrently. Objective To assess the association among training load, injury burden, and performance in professional rugby union. Design Descriptive epidemiology study. Setting The English Premiership competition. Patients or Other Participants Individual injury and training load data, as well as team performance data, were captured during the 2015–2016 (n = 433 players) and 2016–2017 (n = 569 players) seasons. Main Outcome Measure(s) Data were aggregated into team average scores for each week, including weekly (acute) load, smoothed chronic load, changes in load, injury burden, and weekly performance. Linear mixed modelling techniques were used to assess the association among measures. Results Injury burden was negatively associated with performance, with a high weekly burden associated with a likely harmful (P = .01) decrease in performance. Training load measures displayed only trivial associations with performance. Only the acute:chronic workload ratio measure was clearly associated with injury burden, with a possibly harmful effect (P = .02). Both squad size and player availability were associated with only trivial changes in performance. Conclusions Whereas no association between average training load and performance existed, associations between training load and injury burden and between injury burden and performance were clear. Further investigation using more sensitive and individualized measures of load, performance, and injury may elicit a clearer relationship and should be considered for future work.

Purpose: To examine the changes in resisted sprint performance and kinematics provoked by different sled loads in elite sprinters and rugby players. Methods: Eight elite male sprinters and 10 rugby union players performed 20-m sprints under 3 loading conditions (0%, 20%, and 60% body mass [BM]). Sprint time was measured in 0 to 5, 5 to 10, and 10 to 20 m, while stride length and hip, knee, and ankle angles were measured using an 8-sensor motion analysis system at the same distances. Results: Sprinters were significantly faster than rugby players in unresisted and resisted sprints using 20% BM (effect size, “ES” [90% confidence limit, CL] range: 0.65 [0.03 to 1.27]; 3.95 [3.10 to 4.81]), but these differences were not significant at 60% BM. Compared to rugby players, sprinters showed lower velocity decrement in resisted sprints using 20% BM (ES [90% CL] range: 0.75 [0.06 to 1.44]; 2.43 [0.83 to 4.02], but higher velocity decrement using 60% BM (ES [90% CL] range: 1.13 [0.43 to 1.82]; 1.46 [0.81 to 2.11]). No significant differences were detected in stride length between sprinters and rugby players for any sprint condition (ES [90% CL] range: 0.02 [−0.72 to 0.76]; 0.84 [0.13 to 1.54]). Rugby players showed higher hip flexion in resisted sprints (ES [90% CL] range: 0.30 [−0.54 to 1.14]; 1.17 [0.20 to 2.15]) and lower plantar flexion in both unresisted and resisted sprints (ES [90% CL] range: 0.78 [0.18 to 1.38]; 1.69 [1.00 to 2.38] than sprinters. Conclusions: The alterations induced by resisted sprints in sprint velocity and running technique differed between sprinters and rugby players. Some caution should be taken with general sled loads prescriptions, especially when relative loads are based on distinct percentages of BM, as training responses vary among sports and individuals.

Full textAbstract:
Rugby union is a late specialisation sport. As a consequence, youth players may still be engaged in other activities and sports throughout the year as they transition to rugby specialisation. Limited research exists quantifying rugby union training and matches as well as engagement in other activities and sports. Therefore, the aim of this study was to quantify and compare rugby union training, matches and other activities of elite youth U15 and U16 rugby union players at different stages of the season. Four-hundred and ninety-two youth (Under-15 and 16-year-old) rugby union players self-reported the frequency, intensity and duration of their participation in rugby union matches, rugby union training, gym, physical education and other sports during three different stages – September to December (Sept–Dec), January to April (Jan–Apr), May to August (May–Aug) – of the year. When all activities were combined, the frequency and volume of rugby matches and training was the greatest during the Sept–Dec stage. The frequency and volume of participating in other sports increased in the May–Aug stage of the season. Gym training frequency, intensity, and duration were stable across the year for both U15 and U16 players. Coaches and practitioners working with elite youth rugby union players should be aware that players are still participating in other activities outside of rugby training and competition. Coaches and practitioners should put structures in place to plan and monitor players' activities in order to optimise the positive outcomes of specialisation (e.g., expertise) while reducing the potential negative outcomes (e.g., injury, burnout).

Full textAbstract:
This study investigated the effectiveness of rugby-specific video-based perceptual training on the speed and agility of club-level rugby union players. Twenty-six players were randomly divided into either a video-based, field-based or conventional training group. For six weeks, the video-based and field-based groups performed agility training twice a week in addition to their regular rugby training, while the control group was restricted to regular rugby training. Speed, reactive agility and change of direction speed were tested pre- and post-intervention, and after a six-week retention period. Results revealed that both video- and field-based training were almost certainly more beneficial (13% and 17%, respectively) to improve reactive agility compared to conventional rugby training alone. In addition, both intervention groups maintained their reactive agility improvements following the retention period. Consequently, video-based training, likely because of a perceptual component, could be used as an alternative training method to improve reactive agility.

Background: Full contact team sports, such as rugby union, have high incidences of injury. Injury surveillance studies underpin player welfare programmes in rugby union. Objective: To determine the incidence, severity, nature and causes of injuries sustained during the Rugby World Cup 2019.
Methods: A prospective, whole population study following the definitions and procedures recommended in the consensus statement for epidemiologic studies in rugby union. Output measures included players’ age (years), stature (cm), body mass (kg), playing position, and group-level incidence (injuries/1000 player-hours), severity (days- absence), injury burden (days absence/1000 player-hours), location (%), type (%) and inciting event (%) of injuries.
Results: Overall incidences of injury were 79.4 match injuries/1000 player-match-hours (95% CI: 67.4 to 93.6) and 1.5 training injuries/1000 player-training-hours (95% CI: 1.0 to 2.3). The overall mean severity of injury was 28.9 (95% CI: 20.0 to 37.8) days absence during matches and 14.8 (95% CI: 4.1 to 25.5) days absence during training. The most common locations and types of match injuries were head/face (22.4%), posterior thigh (12.6%), ligament sprain (21.7%) and muscle strain (20.3%); the ankle (24.0%), posterior thigh (16.0%), muscle strain (44.0%) and ligament sprain (16.0%) were the most common locations and types of injuries during training. Tackling (28.7%), collisions (16.9%) and running (16.9%) were responsible for most match injuries and non-contact (36.0%) and contact (32.0%) rugby skills activities for training injuries.
Conclusion: The incidence, severity, nature and inciting events associated with match and training injuries at Rugby World Cup 2019 were similar to those reported for Rugby World Cups 2007, 2011 and 2015.

The purpose of this study was to find whether cross training could improve male adolescent rugby skills. Three major sports (soccer, basketball and wrestling) were selected to form the base of the cross training intervention program. Pre- and post-tests were performed with the entire rugby squad (24 participants) prior to and at the conclusion of the intervention program. After pre-testing, the participants were grouped into either the intervention (12) or the control group (12). Supervised cross training sessions were performed twice a week for 10 weeks as well as traditional rugby training twice a week for 10 weeks with the intervention group. The control group performed supervised conventional rugby training twice a week for 10 weeks. All participants (24) played in a rugby match once a week during the 10 week period of the study.

Full textAbstract:
Background: An emerging trend in adolescent sport is a greater emphasis on identifying and developing talent in young athletes and improving articulation to elite adult participation. Adolescent athletes appear to be increasingly engaged in strenuous training processes thought to best serve these ends. The ability to adapt and recover from strenuous physical loading is finite and influenced by many unique factors during adolescence. Consequently, training and non-training stressors and, or, responses to stressors may exceed individual adaptation thresholds with deleterious, rather than beneficial outcomes. Undesirable consequences of training manifest in complex psychosociobiological signs and symptoms, often defined as overreaching or overtraining along the continuum of athlete adaption. For adolescents, undesirable training responses may impact normal growth and maturation, and athlete development, including participation and performance outcomes. In spite of known risks and increasing anecdotal comment on the adolescent athlete, the extent to which high loads of sports participation during adolescence are related to competitive success, serial fatigue, injury, and overtraining are profoundly under explored and knowledge to guide best practice is lacking. Aims: Within a framework of limited existing empirical evidence and in consultation with Australian Rugby Union, studies included in this thesis aimed to serially monitor participation among three levels of adolescent rugby union players to better understand factors contributing to positive performance and participation outcomes and minimising adverse effects including serial fatigue, injury, training errors, and overtraining in the context of the development of talented young athletes.;Methods: For three separate studies, 75, 106, and 118 participants were recruited from various levels of adolescent rugby involvement that included, school, sports selective school, and state representative rugby. Subjective and objective measures of training volume and intensity, game and training practices, and stress and recovery were collected longitudinally. Results: In study one, representative squad players recorded the highest weekly duration of sport and physical activity (515 REPLACE2 222 min/week), followed by the talent squad (421 REPLACE2 211 min/week) and school boy group (370 REPLACE2 135 min/week). Profiles of individual players identified as group outliers showed weekly durations of 730 REPLACE2 49 min/week for a school boy player, 792 REPLACE2 226 min/week for a representative player, and 804 REPLACE2 335 min/week for a talent squad player, including up to three games and up to eleven training sessions per week for this individual. In study two, players with the highest weekly volume of sport and physical activity during the season demonstrated more favourable recovery-stress states compared with moderate and low volume groups. Despite better psychological stress and recovery profiles of more elite, higher load players, not all participants demonstrated favourable capacities to deal with stress and recovery processes. Seven of 106 participants were in at least two of three categories of highest volume, highest stress and poorest recovery. In study three, time-motion analyses showed that compared with rugby training, rugby games were consistently characterised by more time spent jogging (14 vs. 8%), striding (3.2 vs. 1.3%), and sprinting (1.3 vs. 0.1%) (p<0.001). Players also covered greater distances (4000 REPLACE2 500 vs. 2710 REPLACE2 770 m) and performed more sprints (21.8 vs. 1) during games compared with training (p<0.001).;A major finding of this study is the disparity between physical game demands and on-field rugby training practices in adolescent players. Discussion: High-load participation demands of adolescent athletes may compromise optimal energy balance and compete with physiological, psychological, and time resources available for recovery. In team sports such as rugby, monitoring and quantifying load in individual athletes is necessary to facilitate best practice advice for player management and training prescription. It may be even more critical to monitor individual responses among adolescent athletes, in whom varied internal and external loads exist. Even in the absence of a complete understanding the impact of high volume, high stress, poor recovery participation, these markers may be precursors for more deleterious outcomes such as injury, performance decrements, and overtraining. Internal and external pressures, the transition from 'sampling' to 'specialisation', and over-exaggerated short-term performance goals may contribute to the high participation loads found in some adolescent rugby union players. Conclusion: Growth and maturation and adolescent sports' participation create complex challenges for training and developing young athletes. Accumulative training and non-training stressors with inadequate recovery may exceed individual adaptation thresholds with deleterious, rather than beneficial performance and participation outcomes. It would be advantageous to identify 'at risk' individuals and appropriately manage adolescent athletes within redefined developmental frameworks that prioritise long-term goals, are cognisant of growth and maturation, and systematically aim to prescribe loads and recovery to avoid maladaptations.

Study purpose: The objectives of the study were to measure external and internal load and recovery status of junior semi-professional rugby union players (n = 36) during the u/19 Currie Cup campaign. Methods: The monitoring period covered 280 days (July – October) and included phases divided into off-season, pre-season and competition. Twelve league matches were played during the competition phase. The variables associated with external and internal load and recovery status were summarised for each player and also compared to each other to establish relationships between these variables. Data were collected either daily (training load, subjective fatigue and recovery) or weekly (recovery heart rate) or during matches (mechanical load, physiological load and training load). Injuries were also recorded throughout the season. Results: The primary finding of this study was that the players' loads (arbitrary units; AU) (605293 AU), fatigue (4.51.3 AU) and recovery (14.12.3 AU) did not change significantly throughout the different phases of the season. Also, recovery heart remained similar throughout the different phases of the season supporting the pattern of the subjective data. There was no clear predictive relationship between training load, subjective fatigue and recovery prior to sustaining an injury (both soft tissue and musculoskeletal). Conclusion: This study questions the usefulness of a wearable device to measure training load (internal/external), particularly since the session rating of perceived effort(sRPE) is cost effective, quick and easy to implement and provides accurate information. Subjective training load and subjective fatigue did not predict injury in this cohort of players. However, these variables can be used as markers to guide training to ensure the conditioning status of the players remains similar throughout the season. In particular they enable individualised decisions to be made about each player, ensuring that load and fatigue in response to the load remain steady.

Full textAbstract:
Rugby union requires high levels of strength and power in order to support the physical requirements of the game. The competitive structure of rugby union in the English premiership places limitations on the time available for players’ physical development. The aim of this thesis was to analyse the scope and magnitude of strength and power adaptation potential, whilst identifying effective training strategies to support physical development in professional rugby union players. Chapter 3 monitored lower limb strength and power during the different phases of a professional season. This study demonstrated moderate beneficial increases in all physical capacities over a full season whilst pre and mid-season training cycles represent the greatest opportunity for strength and power enhancement. Chapter 4 assessed the efficacy of complex training performed during a mid-season performance phase and found meaningful increases in selected measures of power whilst maximum strength was maintained. Chapter 5 assessed the impact of pre-conditioning exercise mode selection (cycling or weightlifting) when designing complex training interventions and reported highly individualised response patterns in measures of lower and upper body performance. Chapter 5 also demonstrated no clear support for the short-term effects of elevated free-testosterone on local and systemic muscle performance. Chapter 6 investigated the effects that manipulating work interval duration has on fast muscle activity and power during high intensity interval training (HIT). This study reported greater accumulative power responses and fast muscle activation in selected muscles when shorter work interval durations were prescribed. In summary, scope for physical development exists in professional rugby union players. Complex training may be an efficient in-season training method for power development. Hormonal response patterns represent unpredictable markers of acute and chronic improvements in local and systemic muscle performance. Finally, the endurance potential of fast muscle groups may benefit from HIT protocols designed with shorter work interval durations.

The present thesis explored various applications of training specificity with regard to elite-level rugby union football players of various ages. A novel approach to metabolic conditioning employing skill-based conditioning games was investigated with elite-level senior professional players, during the course of a preseason training period. Training responses were assessed using a submaximal intermittent shuttle test performed at weekly intervals. Significant differences post-training (p<0.01) were observed for %HRmax reached during the final test stage and recovery of HR from the end of the final stage to the end of the final 1-minute rest period. The second study examined effectiveness of a circuit format for strength training in elite senior professional players during a preseason training period. Following the circuit based strength training, deadlift and bench pull I-RM strength scores were significantly improved both in comparison to pre-tests (p<0.01) and end season scores (p<0.01). Bench press scores were also significantly improved following the training period (p<0.01), and post-test bench press scores were improved relative to end season scores, albeit to a lesser extent (p<0.05). An Olympic lift training intervention was undertaken with Junior academy-level rugby union players. The effect of the application of these lifts on mean power output measured using test apparatus that simulated the ruck clean movement featured in rugby union football was examined. The considerably greater increases of the training group on this measure (28% vs 8%) were reflected in greater statistical significance (p<0.01) relative to the improvement for the control group (p<0.05). A significant interaction effect also indicated the training groups responded significantly differently on the test measure following training. A weighted ballistic push up training mode, incorporating a prototype shoulder harness, was investigated in a group of junior academy-level rugby football players. The training group recorded significant improvements in work output measured using a concentric-only push test (p<0.05), whereas countermovement push-up test scores approached significance (P=0.063). The final study employed an overweight ball complex training intervention. Following training the elite academy professional players who served as subjects showed significant improvements (p<0.05) in right-handed and left-handed mean and peak pass velocities.

Thesis (M Sport Sc)--Stellenbosch University, 2012.ENGLISH ABSTRACT: Stress and recovery plays an important role in the performance of semi-professional rugby players. Physiological and psychological markers have been established as reliable indicators of the recovery-stress state in athletes. Monitoring changes in the recovery-stress state enables the coaching staff to adapt training sessions to enhance performance. The aim of this study was to monitor changes in stress and recovery states among U-20 rugby union players during a training year. Relationships regarding monitoring variables and differences in stress and recovery between playing positions were examined. 55 Players between the ages of 18 and 20 were monitored for 27 weeks, over a training year. The training year was divided into 5 training phases: Developing phase (week 1 – 7), Transitional phase (week 8 - 11), Early Competition phase (week 12 - 17), Performance phase (week 18 – 24), and High Performance phase (week 25 - 27). Ratings of Perceived Exertion (RPE) for sessions were reported on a daily basis. The Heart-rate Interval Monitoring System (HIMS) test was run every week. The Stellenbosch Mood Scale (STEMS) and Self-Report questionnaires were completed on a weekly basis, and the Recovery-Stress Questionnaire (RESTQ-76-Sport) was completed once a month. Backline players physically recovered better and faster than the forwards throughout the training year, while the forwards exhibited better psychological coping methods. The backline players had significant higher scores for the Depression (p = 0.03), Anger (p = 0.009), and Confusion (p = 0.01) scales of the STEMS. The Total Mood Disturbance scores were also significantly higher (p = 0.03) for the backline players than the forwards during the Performance phase. The backline players experienced increased stress and decreased feelings of well-being during the competitive phases when compared to the forwards. The backline players had better physical recovery than the forwards after the high intensity and high volume Developing phase. Correlations were evident between the HIMS test and the RESTQ-76-Sport questionnaire. Additional correlations were found between training load, as well as training monotony and training strain, and scales of the RESTQ-76-Sport and STEMS questionnaires. Lack of psychological skills-training might also have resulted in the players not knowing how to properly handle stressful situations and how to regulate their stress and recovery states. The lack of an educational system regarding recovery strategies, and the reinforcement thereof, especially during the Developing phases might play a role in the later increased fatigue and injury rates among the players.
AFRIKAANSE OPSOMMING: Stres en herstel speel 'n groot rol in die prestasie van semi-professionele rugby spelers. Fisiologiese en sielkundige merkers is vasgestel as betroubare aanwysers ten opsigte van die stress-herstel toestand van atlete. Die monitoring van veranderinge in hierdie toestand kan die afrigtings-personeel help om die oefensessies aan te pas om optimale prestasie te verseker. Die doel van hierdie navorsingstudie was om veranderinge in stres en herstel toestande in O/20 rugby unie spelers, oor 'n oefenjaar, te moniteer. Verhoudinge in monitering veranderlikes en moontlike verskille in die stress en herstel toestand tussen die voorspelers en agterspelers is ondersoek. 55 Spelers tussen die ouderdomme van 18 en 20 is vir 27 weke, oor 'n oefenjaar, gemonitor. Die oefenjaar was onderverdeel in vyf oefenfases nl. die Ontwikkelingsfase (week 1 – 7), die Oorskakelingsfase (week 8 – 11), die Vroeë Kompetisiefase (week 12 – 17), die Prestasiefase (week 18 – 25), en laastens die Hoë Prestasiefase (week 25 – 27). Spelers het daagliks hul “Rate of Perceived Exertion‟s” aangedui vir elke oefensessie. Die “Heart-rate Interval System” toets (HIMS) was een keer 'n week gehardloop. Die “Stellenbosch Mood States” (STEMS) en Selfrapporteringsvraelyste was op 'n weeklikse basis ingevul en die “Recovery-Stress Questionnaire-Sport” (RESTQ-76-Sport) was een keer 'n maand ingevul. Agterspelers het deur die jaar fisies beter en vinniger as die voorspeler herstel, terwyl die voorspelers beter sielkundige beheer getoon het. Die agterlyn se tellings vir die Depressie (p = 0.03), Woede (p = 0.009), en Vervanging (p = 0.01) skale van die STEMS was betekenisvol hoër as die telling van die voorspelers. Die Totale Gemoedsversteuringstellings was ook betekenisvol hoër vir die agterlyn as die voorspelers tydens die Prestasiefase (p = 0.03). Die agterspelers het toenemende stres tydens die kompetitisie fases ervaar, sowel as 'n afname in die gevoel van Welsyn. Die agterlyn het beter fisiese herstel na die hoë intensiteit en hoë volume Ontwikkelingsfase as die voorspelers getoon. Korrelasies is gevind tussen die HIMS en die RESTQ-76-Sport. Verdere korrelasies is ook tussen “training load”, sowel as “training monotony” en “training strain”, en sekere skale van die RESTQ-76-Sport en STEMS vraelyste gevind. Die tekort aan sielkundige tegniek-ontwikkeling kon bydrae tot die spelers se verwardheid rondom die hantering van stresvolle situasies en hoe om hul stres en herstel toestande te reguleer. Die afwesigheid van „n opvoedkundige sisteem rondom herstel strategieë, en die toepassing daarvan, veral tydens die Ontwikkelingsfases, mag moontlik 'n rol speel in latere toenames in vermoeienis en getal beserings onder die spelers.

Thesis (MEd)--Stellenbosch University, 2011.ENGLISH ABSTRACT: The purpose of the study was to compare the effectiveness of an aquatic- and landbased plyometric programme upon selected, sport-specific performance variables in adolescent male, rugby union players. A group of 52 rugby players (age: 16.3 ± 0.8 years, height: 176 ± 6.9 cm and body mass: 76.1 ± 11.9 kg) were randomly assigned to one of three groups: aquatic group (n=18), land group (n=17), and a control group (n=17). Prior to and after the sevenweeks of training, the power, agility and speed of participants were assessed by means of Fitrodyne repeated countermovement jumps, the Sergeant vertical jump, the Illinois agility test, a standing broad jump, and a 10- and 40- metre sprint. All three groups maintained their summer extra-curricular sport commitments during the intervention period. When the three groups were analysed, no significant differences were found between the groups with regard to all tested performance variables. With regard to withingroup changes, the aquatic group improved significantly (p<0.05) in the Illinois agility test, performed to the right. The land group showed significant (p<0.05) improvements in peak concentric power during Fitrodyne repeated countermovement jumps. All groups reflected highly significant (p<0.01) improvements in the Sergeant vertical jump. None of the groups displayed any improvements in sprint speed. The control was the only group to improve significantly in the standing broad jump (p<0.05). Land-based plyometric training might be a functionally superior training modality for athletes, although aquatic plyometrics could also offer an effective training modality for performance enhancement in power-based sports such as rugby union football. Aquatic-based plyometrics should not completely replace land-based plyometrics, as it might not adequately develop the specific neuromuscular patterns or functional needs of explosive sports.
AFRIKAANSE OPSOMMING: Die doel van hierdie studie was om die effektiwiteit van ‘n water- en landgebaseerde pliometriese program met mekaar te vergelyk in terme van geselekteerde, sportspesifieke uitvoeringsveranderlikes in manlike adolessente rugbyspelers. ‘n Groep van 52 rugbyspelers (ouderdom: 16.3 ± 0.8 jaar, lengte: 176 ± 6.9 cm en liggaamsmassa: 76.1 ± 11.9 kg) is lukraak in een van drie groepe ingedeel: watergroep (n=18), landgroep (n=17), en ‘n kontrolegroep (n=17). Voor en na die sewe-weke oefenprogram, is spelers se plofkrag, ratsheid en spoed getoets deur middel van Fitrodyne herhaalde spronge, Sergeant vertikale sprong, Illinois ratsheidstoets, staande verspring, en ‘n 10- en 40-m spoedtoets. Al drie groepe het vir die duur van die intervensieperiode met hulle somersport aangegaan. Na analise van die drie groepe se data, is daar geen statisties betekenisvolle verskille tussen die groepe ten opsigte van die prestasieveranderlikes gevind nie. Die waterpliometriese groep se prestasie in die Illinois ratsheidstoets na regs het statisties beduidend (p<0.05) verbeter. Die landgroep het betekenisvolle (p<0.05) verbetering in die piek konsentriese plofkrag met die Fitrodyne herhaalde spronge getoon. Aldrie groepe het betekenisvolle (p<0.01) verbetering getoon in die Sergeant vertikale sprong. Geen groep se spoed het verbeter nie. Slegs die kontrolegroep se staande verspring het statisties betekenisvol verbeter. Land-gebaseerde pliometriese oefening kan moontlik, vanuit ‘n funksionele oogpunt, ‘n beter oefenmodaliteit vir atlete wees. Watergebaseerde pliometriese oefening kan egter ook ‘n oefenmodaliteit vir sport wat plofkrag vereis, soos rugby, wees. Watergebaseerde pliometriese oefening behoort nie land-gebaseerde pliometriese oefening te vervang nie, omdat dit moontlik nie aan die spesifieke neuromuskulêre patrone en funksionele behoeftes van eksplosiewe sport voldoen nie.

Full textAbstract:
Sprinting speed is a highly valued physical ability in rugby. There is little research examining sprinting biomechanics in rugby players and it is unclear the extent that sprinting speed and sprint momentum can even be improved in highly trained rugby players and how different speed and strength training methods might help improve it. This thesis consists of 6 studies that examine the sprinting biomechanics of elite rugby players, how strength and power training might improve sprinting speed and the potential for elite rugby players to make further improvement in their sprinting speed and sprint momentum.
Key biomechanical factors were that as a player transitions from a standing start to maximal velocity; they do so without an appreciable change in stride rate but with a substantial increase in stride length. Stride rate remains the same because ground contact time and flight time are inversely proportional with each other as they accelerate from a standing start to maximal velocity. Faster players were found to have lower ground contact times and longer stride lengths for both acceleration and maximal velocity. Sprinting with a rugby ball in one hand did not seem to negatively affect international players in either acceleration phases or maximal velocity phases.
Mass was found to have a negative relationship with acceleration and maximal sprinting velocity. Sprint momentum, on the other hand, was found to have a strong positive relationship with body mass. Body mass and height were found to be higher in successful teams at the 2007 and 2011 Rugby World Cups when compared with less successful teams. Senior international players were found to have much greater sprint momentum and body mass, but not sprinting speed, when compared to junior players. Collectively, all of these results point out that sprint momentum is a highly important physical quality. Sprinting speed is an important outcome of training programs but improving sprint momentum by increasing body mass is probably more important. The senior and junior athletes that were tracked for two years were able to effectively improve their sprinting speed and sprint momentum over a two year period which suggests that these are trainable qualities.
Strength and power were found to be important discriminators between fast and slow players. Faster players showed greater results in power clean, front squat, broad jump and triple broad jump. The relationships between these exercises and acceleration were similar for both the slow and fast groups but these exercises had much stronger correlations with maximal sprinting velocity in the slow group then with the fast group. The differences in these relationships seemed to be explained by ground contact time. The group of highly trained players that were tracked over a one year period did not show positive improvement in sprinting speed from increasing the different strength qualities. An 8 day hypergravity condition for international players was ineffective in producing profound changes in sprinting speed. These results suggest that sprinting speed is a trainable quality but there is a limited capacity for strength training to improve it once these qualities have been reasonably well developed in an elite population.
