Welcome On behalf of the Department of Sport Science, Malm University, Sweden, the Department of Health Sciences, Lund University, Sweden, and the Department of Nutrition, Exercise and Sport, University of Copenhagen, Denmark, it is our pleasure to invite you to attend the 20th Annual Congress of the European College of Sport Science ECSS Malm 2015.

The multidisciplinary ECSS Congress will be celebrating its 20th anniversary. The 2015 congress theme of Sustainable Sport will permeate the academic programme as well as the arrangements: the three universities co-hosting the event all emphasis sustainability

In education and research, and will work together with the City of Malm, a fair trade city, to make ECSS 2015 a sustainable sport con-gress.

The ECSS congress especially emphasises exchange of knowledge through oral and mini-oral presentations, and we are convinced that all attendees will find interesting topics and participate in creating new knowledge within the broad field of Sport Sciences. Once again, the Young Investigators Award will be one of the highlights of the congress.

We look forward to seeing you all in Malm and the resund Region, an area with tremendous social, political, and economic potential in the area of sustainability. Together, we will create an outstanding congress, where we shall develop the broad perspective of sustain-able sport.

RISK FACTORS FOR ANKLE SPRAINS SUSTAINED DURING NETBALL PARTICIPATION

Attenborough, A.S.1, Sinclair, P.J.1, Sharp, T.1, Stuelcken, M.2, Greene, A.3, Smith, R.M.1, Hiller, C.E.1 1 The University of Sydney, Australia. 2 University of the Sunshine Coast, Australia. 3 Anglia Ruskin University, England

Introduction Netball is a sport that places high physical demands on players, requiring them to perform jumping, bounding, pivoting and cutting manoeuvres at high speed. Ankle injuries account for approximately 40% of all netball injuries, with sprains being the most diag-nosed ankle injury (Fong et al., 2007). The identification of risk factors that predict the occurrence of ankle sprains within netball is neces-sary for the development of future prevention programs. Methods Ninety-six netball players were assessed prior to the netball season for the following outcome variables; vertical jump, perceived ankle instability, previous sprain history, arthrometry inversion-eversion angles, star excursion balance test (SEBT) reach distances, number of foot lifts during unilateral stance and demi-pointe balance test. Participants were followed for one netball season and ankle sprains were determined using a time-loss injury definition. A forward sequential logistic regression model determined outcome variable risk factor status. Results Eleven ankle sprains were reported by eleven players. Three outcome variables made a statistically unique contribution to ankle sprain risk; a posterior-medial reach distance of 77.5 % of leg length in the SEBT (OR=3.87, 95% CI=0.90-16.60), an inversion-eversion arthrometry angle of 36.8 degrees (OR=3.86, 95% CI=0.95-15.64) and an inability to maintain unilateral static balance during the demi-pointe balance test (OR=3.46, 95% CI = 0.87-13.80). Possessing all three risk factors would render a player 52 times more likely to sustain an ankle sprain. Discussion The posterior-medial reach distance, which is considered to be the most representative of overall SEBT performance (Hertel et al., 2006), was found to be a risk factor for ankle sprain. Research to create a risk profile screening tool for netball injuries has questioned the inclusion of the SEBT in the assessment (Reid et al., 2014). The current study refutes this and suggests that the posterior-medial direction of the SEBT should remain within the proposed screening tool. Two of the three identified risk factors were balance tests that could be easily administered during preseason prepara-tions for the identification of at-risk players. Interestingly, a previous ankle sprain and the presence of perceived ankle instability had no association with the ankle sprains sustained by the netball players.

EFFECTS OF UNSPECIFIC ENDURANCE EXERCISE ON SPECIFIC SPRINT PERFORMANCE IN INLINE SPEED SKATING

Stangier, C., Abel, T., Hesse, C., Claen, S., Strder, H.K. German Sports University

Introduction: A highly developed aerobic performance level enables inline speed skaters (ISS) to sustain a high average of speed (40 kmh-1) during competition. Since the appropriate period to develop this ability is the winter preseason, due to the weather sport-specific training is not possible. A previous study has shown that unspecific endurance training improves specific endurance capacity (Hildebrand et al. 2014). Generally, a high aerobic capacity is negatively correlated with the sprint performance. However, to be competitive and successful, ISS also require power and swiftness to generate most effective sprints for the mass start, tactical attacks and the finish. Hence, we investigated the influence of nonspecific endurance training (cycling, running) on ISSsport specific sprint performance. Meth-ods: 14 high level ISS (7 male, 7 female, 248 yr, 175.49.7 cm, 67.511.2 kg) were randomly divided in two groups (running, cycling). Training was completed at 60% of VO2max over 7 weeks with 2 sessions per week (81-90 min) each on treadmill or cycle ergometer, respectively. Before and after the training intervention all subjects performed a specific (300 m) and nonspecific (30 s cycling or running) all-out sprint test. To determine the production rate of blood lactate (BLA) and glucose (BGL) one arterialized blood sample (20 l) was taken at rest, as well as ten at one minute intervals after the sprint test. Results: The production rate of BLA decreased significantly (p=0.02) after the specific sprint test without any group effect. The production rate of BGL only showed a significant decrease (p=0.04) after the specific sprint test in the running group. However, the sport-specific sprint performance remained unchanged (29.42.7s, 29.63.7s). No significant changes were found from pre to post for the production rates after the unspecific sprint tests. Conclusion: Since the study was conducted during the preseason, the absent loss of sprint performance can be considered as positive, indicating that nonspecific training at 60% of VO2max stabilises ISS sprint performance. Moreover, the decreased production rate for BLA enables the athletes to recover faster from high intensity sprints. The lower production rate of BGL for all athletes who trained in the running group should be considered for optimal endurance training. The results suggest this type of unspecific training presents a greater stimulus for the sport-specific fat metabolism than cycling, resulting in a more economic energy supply (Jeukendrup, 2002).

THE IMPACT OF DATA AVERAGING STRATEGIES ON VO2MAX

Martin-Rincon, M.1, Perez-Valera, M.1, Rodrguez-Afonso, K., Cherouveim, E., Curtelin, D., Losa-Reyna, J., Sanchez Torres-Peralta, R., Ponce, J.G., Morales, D., Dorado, C., De Pablos, P., Calbet, J.A. Univ. of Las Palmas de G. Canaria, Spain; Univ. Athens, Greece.

Introduction Given the high breath-to-breath variability of respiratory variables, it is considered that including a greater number of breaths in averaging intervals will reduce variability between tests. However, the VO2max is only achieved during a short interval and therefore long averaging intervals may result in underestimation of the actual VO2max. The aim of the study was to determine the impact of the number of breaths included in the averaging interval on the reliability of VO2max measurements and on the absolute VO2max value. Methods After familiarisation, 40 men and 22 women performed two incremental exercise (IE) tests to exhaustion in two weeks. Five different IE protocols were used: ramp (15 or 20W/min) and steps (25, 30 or 35 W/2min) (Lode, Excalibur, Netherlands), all adjusted to reach a minimal IE duration of at least 6 min. Respiratory variables were measured breath-by-breath (Vmax N29; Sensormedics). The last two minutes of IE were analysed to determine the VO2max using rolling averages including from 6 to 60 breaths. The individual coeffi-cient of variation (CV) was determined for each averaging strategy. Results The highest mean CV value (5.93%, range:0.04-21.8%) was obtained with 6 breaths and the lowest with 21 (4.85 %, range: 0-23.5%, n=61). For more than 21 breaths the CV increased progressively with the number of breaths. No significant differences in CVs were observed between sexes, protocol or fitness status. The averaging strategy had a major influence on the imputed VO2max values. VO2max values were higher, the lower the averaging interval (P

ASSOCIATIONS BETWEEN VARIOUS INTENSITIES OF PHYSICAL ACTVITY AND PHYSICAL FITNESS IN ADOLESCENTS

Kidokoro, T.1, Yanaoka, T.1, Kashiwabara, K.1, Yamagami, J.1, Tanaka, H.2, Miyashita, M.1 1: Tokyo Gakugei University (Tokyo, Japan); 2: Yokohama National University (Kanagawa, Japan)

Introduction While a positive association between physical activity and physical fitness has been established in adults, the association appears less clear in adolescents (Dencker and Andersen, 2011). The purpose of this study was to examine associations between objec-tively measured various intensities of physical activity and eight physical fitness tests in Japanese adolescents. Methods A total number of 289 Japanese adolescents (age, 13 1 (mean SD) years; 140 boys and 149 girls) participated in this cross-sectional study. To evaluate the amount of time spent in moderate to vigorous ( 3 Mets) physical activity (MVPA), and vigorous ( 6 Mets) physical activity (VPA), participants were asked to wear a uniaxial accelerometer (Lifecoder-EX, Suzuken Co. Ltd.) for 14 consecutive days. Physical fitness tests are comprised of eight tests including 1) distance running, 2) 50 m sprinting, 3) grip strength, 4) bent-leg sit-up, 5) side step, 6) sit-and-reach, 7) standing long jump and 8) handball throw. Based on data obtained through accelerometers (i.e., MVPA and VPA), the partici-pants were grouped into quartile categories (Q1 (Least active) ~ Q4 (Most active)). Adjusted logistic regression analyses were performed to examine the odds ratios (ORs) and 95% confidence intervals (95% CI) of being in the lowest physical fitness quartile categories for each variable according to physical activity quartile categories (Q1 ~ Q4). Results In both sexes, MVPA was negatively associated with distance running time (r < -0.24, p < 0.05), and the association was stronger between VPA and distance running time (r < -0.33, p < 0.001). Ad-justed logistic regression (reference category: VPA-Q1) revealed that there was a significant difference in bent-leg sit-up (ORs = 0.18, 95% CI: 0.05-0.69) and handball throw (ORs = 0.20, 95% CI: 0.05-0.81) in VPA-Q4, and distance running (QRs = 0.22, 95% CI: 0.06-0.79) in VPA-Q3 for boys. For girls, there was a significant difference in distance running (QRs = 0.03, 95% CI: 0.01-0.20), 50 m sprinting (QRs = 0.24, 95% CI: 0.07-0.82), bent-leg sit-up (QRs = 0.10, 95% CI: 0.02-0.40), side step (QRs = 0.11, 95% CI: 0.03-0.47) and handball throw (QRs = 0.30, 95% CI: 0.09-0.99) in VPA-Q4 compared to VPA-Q1. Discussion These findings may suggest that increasing the amount of time spent physical activity, in particular vigorous physical activity, appears to be an effective strategy for improving physical fitness in this population.

THE CONTRIBUTION OF SKELETAL MUSCLE VOLUME AND ARCHITECTURE TO SOCCER-SPECIFIC POWER IN ELITE AND RECREATIONAL YOUTH SOCCER PLAYERS

Murtagh, C.F.1,2, Nulty, C.1, Stubbs, M.1, Vanrenterghem, J.1, OBoyle, A.2, Morgans, R.1,2, Drust, B.1,2, Erskine, R.M.1 1-Liverpool John Moores University, Liverpool, UK. 2-Liverpool Football Club, Liverpool, UK

Purpose: The activity profile in elite soccer match-play is characterised by frequent bursts of explosive activity most often performed in the horizontal direction. The physiological determinants of horizontal explosive performance in elite soccer players have yet to be elucidated. Such information may inform talent identification, physiological assessment protocols and training prescription. This study investigated the potential differences in kinetic and kinematic variables between elite and non-elite soccer players during unilateral horizontal coun-termovement jump (ULHCMJ) performance and the physiological factors that underpin these differences. Methods: A cohort of elite (n=23; age, 18 1 yrs; BMI, 23.1 1.8) and recreationally trained non-elite (n=20; age, 22 3 yrs; BMI, 23.8 1.8) soccer players per-formed three ULHCMJs on a force platform. Ultrasonography was used to measure the volume (Vm) and anatomical cross-sectional area (ACSA) of the quadriceps femoris muscle (QF), and the architecture (fascicle length, Lf; fascicle pennation angle, FPA) of the vastus lateralis muscle (VL). The contributions of these characteristics to horizontal jump performance were assessed using bivariate correlation anal-yses. Results: Elite soccer players elicited greater jump distance (Elite: 216.0 14.9 cm, Non-elite: 196.1 15.9 cm; P < 0.001), peak vertical power (Elite: 1768.2 389.6 W, Non-elite: 1439.2 278.5 W, P = 0.004) and take-off velocity (Elite: 216.0 14.9 ms-1, Non-elite: 196.1 15.9 ms-1, P = 0.013) compared to non-elite players. They also had greater QF Vm (Elite: 2853 508 cm3, Non-elite: 2429 232 cm3; P = 0.001) and QF ACSA (Elite: 80.8 15.8 cm2, Non-elite: 69.8 6.7 cm2, P = 0.006). There were no differences in VL Lf (Elite: 12.7 1.8 cm, Non-elite: 12.8 1.7 cm; P = 0.908) or FPA (Elite: 14.9 2.2 deg, Non-elite: 14.6 2.0 deg; P = 0.722). QF Vm and ACSA correlated with CMJ distance (Vm: r = 0.366, P = 0.016; ACSA: r = 0.348, P = 0.022) and peak vertical power (Vm: r = 0.554, P < 0.0003; ACSA: r = 0.519, P = 0.001). Muscle architecture (neither Lf nor FPA) correlated with any measure of ULHCMJ performance (all, P > 0.05). Conclusion: Uni-lateral horizontal explosive capability appears to be an important characteristic of elite youth soccer, and QF Vm and ACSA play signifi-cant roles in determining soccer-specific power performance. Practitioners working with talent development programmes should consid-er the inclusion of regular assessment and development of QF Vm to optimise performance in youth soccer players.

EFFECT OF THE SOURCE OF DIETARY NITRATE SUPPLEMENTATION ON PLASMA NITRITE CONCENTRATIONS AND BLOOD PRESSURE

Jonvik, K.L.1,2, Nyakayiru, J.1, Pinckaers, P.J.M.1, Senden, J.M.G.1, van Loon, L.J.C.1,2, Verdijk, L.B.1 1: Maastricht University 2: HAN University of Applied Sciences

BACKGROUND Dietary nitrate (NO3) has recently received increased attention due to its potential ergogenic and clinical benefits. The ingestion of dietary nitrate from different inorganic sources (e.g. NaNO3, beetroot juice) has been shown to result in elevated plasma nitrate and nitrite levels, thereby increasing the bio-availability of NO. However, it is currently unknown to what extent the actual source of nitrate may affect the subsequent physiological effects upon ingestion. PURPOSE: To assess the acute effects of different nitrate-rich food

sources on plasma nitrate and nitrite levels and resting blood pressure in healthy individuals. METHODS Using a randomized cross-over design, 11 male and 7 female recreationally active subjects (281 y, BMI 231 kg/m2) ingested four different beverages, each providing 800 mg (~12.9 mmol) nitrate: sodium nitrate (1.1 g dissolved in water; NaNO3), concentrated beetroot juice (116 g; BRJ), a rocket salad beverage (196 g; RS), and a spinach beverage (365 g; SP). Blood pressure was measured at baseline, 2.5 h and 5 h following ingestion. Blood was drawn before, and up to 5 h following ingestion and was analyzed for plasma nitrate and nitrite concentrations. Data were analyzed using repeated measures ANOVA with time and treatment as within-subject factors, with Bonferroni-corrected post hoc testing. Plasma nitrite concentrations represent preliminary data from n=9. RESULTS Peak plasma nitrite concentrations were higher in SP (794148 nM) compared with NaNO3 and BRJ (54180 and 51576 nM, respectively; P

DELAYED INSULIN ACTION DURING OGTT IN HABITUAL LOW-CARBOHYDRATE HIGH-FAT CYCLISTS

Leith, D., Webster, C., Smith, J., Noakes, T. University of Cape Town

Introduction Low-Carbohydrate High-Fat (LCHF) diets have recently received attention for their potentially positive influence on prolonged endurance performance and athlete well-being (Noakes et al., 2014). Literature is scarce on the macronutrient composition and metabo-lism of competitive athletes habitually consuming a LCHF diet compared to matched athletes on a diet higher in carbohydrate content. This study sought to compare the dietary intake and insulin sensitivity of trained cyclists having habitually consumed (> 6 months) either a LCHF or mixed control (CON) diet. Methods Fourteen (7 LCHF, 7 CON) endurance-trained male cyclists (VO2max 61 5 mlkg-1min-1 LCHF; 63 8 mlkg-1min-1 CON), matched for age (36 6 LCHF; 32 5 CON), body composition (BMI 23.6 1.8 LCHF; 23.4 2.0 CON) and relative peak power output (4.8 0.4 Wkg-1 LCHF; 5.0 0.4 Wkg-1 CON), were recruited. Participants completed a 3-day dietary record - analysed by the Automated Self-Administered 24-hour Recall (ASA24) analysis software. After an overnight fast, a resting blood sample was taken, followed by a 2-hour 75g oral glucose tolerance test (OGTT). Insulin-sensitivity was assessed by the Homeostatic Model Assessment (HOMA-IR) and the Matsuda Index. Results Dietary intake was similar between groups except fat and carbohydrate consumption (Protein/Fat/Carbohydrate: 21%, 1.9 gkg-1d-1 / 72% / 7% LCHF; 16%, 1.8 gkg-1d-1 / 33% / 51% CON). HOMA-IR scores were not significantly different between groups (1.04 0.52 LCHF; 0.89 0.40 CON, p=0.80). LCHF tended to have a lower Matsuda Index compared to CON (1.53 0.64 LCHF; 2.29 0.85 CON, p = 0.07). At all OGTT time points after baseline, plasma glucose was significantly higher in the LCHF group (p70%) from fat in line with prescribed high-fat athletic diets. LCHF cyclists did not present with insulin-resistance (Gayoso-Diz et al., 2013) nor impaired glucose tolerance (Nathan et al., 2007). However, delayed glucose disposal in response to elevated insulin suggests reduced metabolic flexibility: specifically a reduced capacity to metabolise ingested carbohydrate. This is likely due to adaptation to fat as a preferred fuel source and concomitant down-regulation of enzymes involved in carbohydrate oxida-tion (Phinney et al., 1983).

EFFECTS OF BLOOD DONATION AND NITRATE INGESTION ON THE PHYSIOLOGICAL RESPONSE TO MODERATE-INTENSITY AND INCREMENTAL EXERCISE

McDonagh, S.T.J., Vanhatalo, A., Fulford, J., Wylie, L.J., Bailey, S.J., Jones, A.M. University of Exeter

Introduction Nitrate-rich beetroot juice (BR) can reduce the oxygen (O2) cost of moderate-intensity exercise and enhance tolerance to severe-intensity exercise (Bailey et al., 2009). A derivative of nitrate (NO3-), nitric oxide, plays a significant role in the regulation of skeletal muscle blood flow, contraction and efficiency. A reduction in blood O2 carrying capacity, as a result of blood donation, reduces the toler-ance to severe-intensity exercise (Burnley et al., 2006). The aim of this study was to determine whether BR supplementation alters the haemodynamic response, efficiency and tolerance to cycling exercise post blood donation. Methods In a randomised and double blind experimental design, 22 recreationally active volunteers performed moderate-intensity and ramp incremental cycle exercise tests prior to and post withdrawal of ~450 mL of whole blood. Before donation, all subjects (n=22) consumed 7 x 70 mL of NO3--depleted beetroot juice shots (~0.04 mmol NO3- per 70mL) as a placebo (PL) in the 48 h preceding the exercise tests. Immediately after blood donation and during the 48 h prior to exercise, subjects consumed 7 shots of either BR (~6.2 mmol NO3- per 70 mL; n=11) or PL (n=11). Blood pressure (BP), plasma NO3- and nitrite (NO2-) concentrations, haemoglobin concentration ([Hb]), haematocrit (Hct) and pulmonary VO2 responses to exercise were measured during each visit to the laboratory. Results BR supplementation resulted in an increased plasma [NO3-] (PL: 5014 vs. BR: 845350 M; P

LOW VOLUME SPEED-ENDURANCE TRAINING IMPROVES INTERMITTENT EXERCISE CAPACITY IN HIGHLY TRAINED FOOTBALL PLAYERS IN SEASON: ROLE OF SKELETAL MUSCLE ADAPTATIONS.

Gunnarsson, T., Fiorenza, M., Nyberg, M., Piil, P., Lund, A.P., Rmer, T., Bangsbo, J. University of Copenhagen

Introduction. The present study examined, whether 9 weeks of speed-endurance training (SET) in season would improve the intermittent exercise capacity and running economy in highly trained football players and, to what extent this improvement was associated with training-induced muscular adaptations in regards to muscle ion transport capacity and glycolytic metabolism in type I and II fibers. Meth-ods. Thirteen highly trained football players completed (meansSD) 9.41.7 training sessions of SET during the last 9 weeks of the season corresponding to an adherence of 72.213.1 % of total number of planned SET sessions. SET consisted of 2-3 sets of 6-10 x 5 s all-out sprinting interspersed by 10 s of recovery with 2 min of recovery between sets. SET was always performed at the end of training sessions and the average number of sprints per training session was 203. A resting muscle biopsy was obtained from m. vastus lateralis before and after the 9-week intervention period. In addition, running economy was measured before and after the intervention period on a motorized treadmill during two successive running bouts for 6 and 4 minutes at 10 and 16 kmh-1, respectively. Results. As a result of the intervention period, the Yo-Yo Intermittent Recovery Test level 1 (YYIR1) performance improved (p



Hbmass in LHTL+C compared with CON (p = 0.03). VO2max increased by ~3% within both CLASSIC and LHTL+C but was not statistically greater than the 1% increase in CON. There was a ~9% increase in TTE after LHTL+C and a ~8% increase after CLASSIC; both increases were likely greater than the smallest worthwhile change of 3.0%. Discussion These findings indicate that, for elite athletes undertaking altitude training, our combined classic and LHTL method is an effective alternative to conventional camps at moderate altitude. This is especially relevant in countries in which the topography is less than 2000 m. We recommend that low altitude (1380 m) combined with sleeping in altitude tents (3000 m) is a time efficient method to improve Hbmass and VO2max, with the advantage of less compromised training intensity compared with traditional altitude methods typically conducted at higher altitudes of 2000-3000m.

Introduction Recent research has shown that mental fatigue impairs intermittent running performance in a task with similar demands to a soccer match (Smith et al. 2015). Further research has reported reductions in perceptual and motor skills of mentally fatigued athletes (Duncan et al. 2015). However, it is unknown whether these results from laboratory-based investigations directly translate into impair-ments in soccer-specific performance. Therefore, this study investigated the effects of mental fatigue on soccer-specific skill performance. Methods In this double-blind, randomized, counterbalanced cross over investigation, we tested soccer-specific skill performance in 14 male soccer players (age: 19.6 3.5 y; experience: 13.6 3.2 y). Players performed the Loughborough Soccer Passing (LSPT) and Shooting Tests (LSST) on two occasions, separated by a minimum of 48 h. The LSPT and LSST were preceded, in a randomised order, by 30 min of mentally fatiguing reading (Stroop task) or emotionally-neutral reading (magazines; control). Subjective mental fatigue was recorded on visual analogue scales before and after reading. Subjective reports of mental effort (for the reading task) and motivation (for the skills tests) were also recorded after reading. LSPT performance was assessed using original time, penalty time, and performance time (origi-nal time + penalty time). LSST performance was assessed using shot accuracy, shot speed, and shot sequence time. Results Reports of mental fatigue and effort were higher following the Stroop task than the magazines (both P < 0.001), while motivation was similar be-tween conditions. LSPT original time was not different between conditions but penalty time was significantly higher in the mental fatigue condition (4.9 7.6 s vs. 0.0 6.2 s; P = 0.005, d = 0.71), resulting in a slower performance time (52.6 6.6 s vs. 47.9 7.7 s; P = 0.014, d = 0.66). Players performed less accurate (1.3 0.6 points vs. 2.0 0.5 points; P = 0.006, d = 1.20) and slower (81.8 4.7 km/h vs. 85.0 5.6 km/h; P = 0.024, d = 0.63) shots when mentally fatigued. Average shot sequence time was not significantly different between condi-tions (P = 0.08). Discussion Mental fatigue impaired soccer-specific skill performance. Indeed, players made more passing and ball control errors, and performed slower, less accurate shots on goal when mentally fatigued. Combined with recent findings that mental fatigue impairs intermittent running performance (Smith et al. 2015), this novel finding has several important implications for soccer play-ers and coaches.

TACKLE TECHNIQUE AND RISK OF INJURY IN HIGH-LEVEL UNDER-18 SOUTH AFRICAN RUGBY UNION PLAYERS

Burger, N., Lambert, M.I., Readhead, C., Viljoen, W., Brown, J.C., Hendricks, S. University of Cape Town

Introduction The incidence of injury in rugby union is high in comparison to other team sports (Brown et al., 2012). Tackle technique has been identified as a major injury risk factor (McIntosh et al., 2010). Previous research has reported on tackle characteristics associated with injury but not specifically on technical tackle criteria (McIntosh et al., 2010; Fuller et al., 2010). Therefore, the aim of this study was to assess tackle technique proficiency in youth rugby union players. Methods Injury surveillance was conducted at the 2011-2013 under-18 Craven Week rugby tournaments. Video footage of 49 tackle injury events (23 ball-carries, 26 tackles) and 249 non-injury events (126 ball-carries, 123 tackles) were identified. Each ball-carry/tackle was analysed using standardised technical proficiency criteria. Overall and individual criteria score means and standard deviations were calculated for front-on and side-on/behind tackles for ball-carriers and tacklers. T-tests and effect sizes were calculated to compare injury and non-injury events. The level of significance was set at p

Introduction Efficient management of athlete preparation can only be realized through a comprehensive analysis of all components of the training process; including daily physiological feedback. The purpose of this study was to determine the most important training and non-training related contributors to game success and the optimization of the training process to achieve the best results. Methods The study examined 14 players of a professional rugby team during the 2013-14 season. The data contained anthropometrical, physiological, performance, training load and self-reported wellbeing variables. Physiological readiness of the Central Nervous System, Cardiac System (CS) and Autonomic Nervous System (ANS) were frequently monitored by Omegawave Team+ (Finland).
