Do We Share the Same View? Validating the Shared Mental Models in Team Sports Questionnaire.

Shared mental models (SMMs) can exert a positive influence on team sports performance because team members with SMMs share similar tasks and team-related knowledge. There is currently insufficient sports research on SMMs because the underlying theory has not been adapted adequately to the sports context, and different SMMs measurement instruments have been used in past studies. In the present study we aimed to externally validate and determine the construct validity of the "Shared Mental Models in Team Sports Questionnaire" (SMMTSQ). Moreover, we critically examined the theoretical foundation for this instrument. Participants were 476 active team athletes from various sports. While confirmatory factor analysis did not support the SMMTSQ's hierarchical model, its 13 subfactors showed a good model fit in an explorative correlative approach, and the model showed good internal consistency and item-total correlations. Thus, the instrument's subfactors can be applied individually, even while there are remaining questions as to whether other questionnaires of this kind are an appropriate means of measuring SMMs in sport.

Does the League Table Lie? The Development and Validation of the Perceived Performance in Team Sports Questionnaire (PPTSQ).

Objective performance measures are vastly used in sport psychology despite their inherent limitations (e.g., unaccounted baseline differences). Founded on the nature of group goals in team sports, we aimed at developing the Perceived Performance in Team Sports Questionnaire (PPTSQ) to capture the team members’ perception of their team’s performance. Accordingly, three dimensions were hypothesized: effort investment, skills execution, and perceived outcome. To measure these dimensions, items were generated to address the players’ perception of their team performance as a whole. Four samples of athletes were used to test the psychometric properties of the PPTSQ: professional (n = 231), collegiate (n = 222), professional—retest (n = 89), and mixed professional–collegiate (n = 139). Exploratory and confirmatory factor analyses were used to estimate construct and content validities. These procedures revealed a better data fit to a two-dimensional model that consists of effort investment and perceived outcome. The reliability analyses for the PPTSQ provide satisfactory evidence that the questionnaire is a reliable measure of perceived performance in team sport. Adequate internal consistency emerged for both dimensions (0.75 < ω < 0.89). Furthermore, a high correlation was obtained for temporal stability. Concurrent validity was addressed by correlating the PPTSQ scores with the Group Environment Questionnaire and the Team Assessment Diagnostic Instrument. Correlational analysis between the PPTSQ and an objective measure of performance was used to test its predictive validity. The correlations strongly support the concurrent and predictive validities of the PPTSQ. We conclude that our perceived performance questionnaire can address various objective measures shortcomings (e.g., considering base-rate biases) resulting in a more meaningful team performance metric. Implication of the PPTSQ for sport psychology research and applied work enhancement are discussed in detail.

Comparison of the validity and reliability of local positioning systems against other tracking technologies in team sport: A systematic review

Given the accuracy in data collection, radar-based local positioning systems (LPS) are a promising technology to monitor training load in team sports. The objective of this study was to systematically review articles that compare the validity and reliability of LPS to other electronic performance and tracking system (EPTS) in team sports. The authors searched three electronic databases (SPORTDiscus, PubMed, and Web of Science) to identify relevant studies published by October 21, 2019. A Boolean search was performed, including sport ( population), search terms related to intervention technology ( intervention technology), and outcome measures of the technology ( outcomes). Seven studies evaluated the validity and reliability of LPS in team sports in comparison with other EPTS, including semi-automatic video technology (VID) and Global Positioning System (GPS). Two articles compared LPS to VID, three articles compared LPS to GPS, and two articles compared LPS to both GPS and VID. LPS is considered a valid and reliable EPTS in the field of load monitoring of team sports, usually resulting in higher accuracy than VID or GPS. However, special care should be taken when analyzing load indicators at high speeds or different trajectories, since the validity and reliability depend on the EPTS itself.

RETRACTED: Athlete muscle measurement and exercise data monitoring based on embedded system and wearable devices

Wearable devices are considered to evaluate the performance of athletes during sports activities. Preliminary steps include recording motion variables at a sufficiently high sample rate throughout the test series. Load tracking sports science has become a very popular topic for athletes who are trained and competitive. Experiential research and process-based research have produced a rapid increase in the use of the dental approach by scientists and trainers to monitor the training load routinely and to capture the best way of capturing and interpreting data. This field has developed at such a rapid pace. In recent years, it has led to the development of new and novel model businesses that accurately place loads inside and outside to protect athletes and help them measure—protection from injury and poor health. Using Support Vector Machines (SVMs) to guide training and monitor athlete muscle measurement's well-being to detect any improvement in measures against poor team related to poor physical health effects all options and mechanisms required are proposed in the system analysis. Tracking application can be wearable technology that calculates the biomechanical and physiological parameters of athletes. Scored the second goal, that collaborative research opportunities between academic groups, sports medicine clinics, and sports team performance programs could help stream players across different sports fields use this technology. A supplementary biochemical profile and the use of wearable devices to track an athlete's mental intelligence were discussed. Key Indicator Value Not Available Using one wireless network connection can send other electronic devices at transmission speeds for reduction. Some experimental data have been reported on this method.

Nutritional strategies to optimize performance, ­training adaptation and recovery in team sports

Team sports performance is highly demanding in terms of physiological and psychological aspects. Furthermore, the competition schedule is often time constrained and athletes need to travel between games during recovery. Therefore, it seems very important to optimize nutritional strategies around training sessions as well as while traveling or competing. This review discusses a variety of different aspects, which are important in the development of a nutritional strategy in a club. It summarizes how the medical and performance staff of a team can provide the right nutritional strategies to optimize training adaptation and recovery. Furthermore, specific nutritional aspects for female, youth and traveling athletes as well as athletes recovering from injury are discussed. Besides nutritional strategies, teams should be cautious regarding the monitoring of body composition. Choosing the right time point in the season together with selecting a reliable and valid method and measuring under standardized circumstances is essential. Furthermore, athletes need to be educated on the risks and benefits of supplement use. This can reduce the risk of a positive doping test as well as the use of unnecessary, inappropriate and ineffective supplements.

Tactical performance in soccer: The importance of choosing and properly applying tactical assessment tools

BACKGROUND: Several tactical assessment tools have been proposed to evaluate players’ tactical performance in more representative contexts. AIM: Investigate the associations between the results from different tactical assessment tools, TSAP and FUT-SAT, in youth soccer players. METHOD: Twenty-seven male U-11 soccer players participated in the study (mean age = 11.02 ± 0.78 years). The players' technical-tactical performance was analyzed using the Team Sports Performance Assessment Procedure - TSAP. The players' tactical performance and behavior were assessed using the Football Tactical Assessment System - FUT-SAT. Pearson's correlation test was used to analyze the association between the performance indexes obtained through both assessment tools. RESULTS: With the results obtained, it was possible to verify that both assessment tools' performance indexes did not present a significant correlation. CONCLUSION: Through these results, it is possible to conclude that it is extremely necessary for the correct choice of the assessment tools to be used, considering their characteristics and limitations, as well as their relation with tactical content to be emphasized during the learning process.

Sports team performance and revenue of out-of-stadium vending operations

ABSTRACT Using a novel data set on daily sales revenue, we examine how the Baltimore Orioles’ performance affects a street vendor operating outside Oriole Park at Camden Yards. While fans respond positively to good team performance throughout the season, a win for the home team generally means lower revenue for the vendors outside the stadium. We find that economic benefits accruing to street vendors – and by extension to nearby hotels, restaurants, and bars – may only be maximized when the sports teams are bad, but not that bad.

Sleep Hygiene and Light Exposure Can Improve Performance Following Long-Haul Air Travel.

To assess the efficacy of a combined light exposure and sleep hygiene intervention to improve team-sport performance following eastward long-haul transmeridian travel. Twenty physically trained males underwent testing at 09:00 and 17:00hours local time on 4 consecutive days at home (baseline) and the first 4 days following 21hours of air travel east across 8 time zones. In a randomized, matched-pairs design, participants traveled with (INT; n = 10) or without (CON; n = 10) a light exposure and sleep hygiene intervention. Performance was assessed via countermovement jump, 20-m sprint, T test, and Yo-Yo Intermittent Recovery Level 1 tests, together with perceptual measures of jet lag, fatigue, mood, and motivation. Sleep was measured using wrist activity monitors in conjunction with self-report diaries. Magnitude-based inference and standardized effect-size analysis indicated there was a very likely improvement in the mean change in countermovement jump peak power (effect size 1.10, ±0.55), and likely improvement in 5-m (0.54, ±0.67) and 20-m (0.74, ±0.71) sprint time in INT compared with CON across the 4 days posttravel. Sleep duration was most likely greater in INT both during travel (1.61, ±0.82) and across the 4 nights following travel (1.28, ±0.58) compared with CON. Finally, perceived mood and motivation were likely worse (0.73, ±0.88 and 0.63, ±0.87) across the 4 days posttravel in CON compared with INT. Combined light exposure and sleep hygiene improved speed and power but not intermittent-sprint performance up to 96hours following long-haul transmeridian travel. The reduction of sleep disruption during and following travel is a likely contributor to improved performance.

Accuracy, inter-unit reliability and comparison between GPS and UWB-based tracking systems for measuring centripetal force during curvilinear locomotion

Curvilinear locomotion is important for team sports performance and requires data collection and monitoring of centripetal forces. Currently, the centripetal force can be measured by different sensors that compose inertial devices, but its accuracy needs to be assessed. Therefore, this research aimed to analyze the accuracy and inter-unit reliability of both global positioning (GPS)-based and ultra-wideband (UWB)-based systems for practical application in the field. Following institutional ethical approval and familiarization, 10 elite-level male soccer players performed six circuits on four tracks (6-m radius circle, 9.15-m radius circle, 12-m radius circle, and combined track locomotion) in both directions (three counter-clockwise and three clockwise) and were monitored by two tracking systems (GPS and UWB). The direct measurement was compared with the theoretical centripetal force calculated by photocells and spatial references. The UWB technology showed better accuracy (clockwise, bias =−1.34 N; counter-clockwise, bias = 1.09 N) than the GPS (clockwise, bias = −2.19 N; counter-clockwise, bias = 1.75 N) in centripetal force measurements. However, both tracking technologies obtained very large to nearly perfect reliability results (GPS: ICC = 0.76-0.96; UWB: ICC = 0.76–0.98). In conclusion, even though both technologies proved to be reliable and data could be compared between units, the UWB-based system demonstrated better accuracy than the GPS-based system to detect centripetal force during curvilinear locomotion.

Node and Network Entropy—A Novel Mathematical Model for Pattern Analysis of Team Sports Behavior

Pattern analysis is a well-established topic in team sports performance analysis, and is usually centered on the analysis of passing sequences. Taking a Bayesian approach to the study of these interactions, this work presents novel entropy mathematical models for Markov chain-based pattern analysis in team sports networks, with Relative Transition Entropy and Network Transition Entropy applied to both passing and reception patterns. To demonstrate their applicability, these mathematical models were used in a case study in football—the 2016/2017 Champions League Final, where both teams were analyzed. The results show that the winning team, Real Madrid, presented greater values for both individual and team transition entropies, which indicate that greater levels of unpredictability may bring teams closer to victory. In conclusion, these metrics may provide information to game analysts, allowing them to provide coaches with accurate and timely information about the key players of the game.

Women’s National Volleyball - Basketball teams in Albania performed in Drop Jump 60 cm

Volleyball and Basketball women’s have different performances from each other due to their special specifics of the game. From the specificity of their training, there are differences in the physical qualities of individual and team sports performance, where one of the elements is vertical jumping. This study is concentrated on two teams: Women’s Volleyball Team (V) and Women’s Basketball Team (B) 15 members each, focusing on 30 subjects. Players were measured in physical parameters; Age (V-24: B-27), Body Height (V-180.4cm; B-173.4cm), Body Weight (V-70.37kg; B-63.88kg), BMI (V-21.67 percent; B-20.93 percent). The players performed the test DJ60cm in the platform Leonardo Ground Force Reaction Plate (GRFP) which expresses Force max (kN), Power max (w/kg), Time Contact (TCs), Air Time (TAs), TA/TCs. The results obtained by GRFP showed different team values of the two sports in the parameters of Fmax V65.19-B74.07n/kg, Pmax V31.26-B23.06w/kg, TCs V0.231-B0.198, TAs V0.436-B0.34 and TA/TCѕec V1.96ѕ-B1.71ѕec. Results revealed that V players jumped higher (p, 0.001) than B players. Finally, the Drop Jump60cm test has different performance between individual players, despite the fact that in the team average it turned out that Volleyball players is higher in this test. Drop Jump is the typical plyometric test. Furthermore, tests such as DJ can be a useful method for assessing differences and monitoring vertical jump training programs from collective sports.

Perceptions of Coaching Behavior and Its Impact on Managerial of Team Sports Performance

Sports coaches being important factors that affect athletes learning and development. Sports coaches fulfilling instructional, strategies, social relationship and psychosocial outcomes for athletes’ development. Managerial coaching is an essential element of management in human resource development to improve individual performance. Coaching behaviour has key elements to improve individual or team performance. Therefore, this research aimed to investigate the athlete’s perception of coaching behaviour in team sport athletes. 120 athletes from three (3) team sport, i. Football (n=40), ii. Netball (n=40) and iii. Hockey (n=40) completed a questionnaire pack assessing the study variables. Results revealed that there were significant differences perceived “Physical Training” between genders, and “Positive rapport” between genders. Results also indicated significant differences between all the three (3) team sports for physical training, positive rapport behaviour, and negative rapport behaviour. The findings of this study suggest athletes’ perceptions of their coach’s behaviour influence by athletes’ predilection through gender and types of sports. Thus, athletes’ perceptions of their coach behaviour have important values for coach’s approaches and management on team sports performance.

The Performance Effect of Scheduled Carbohydrate and Caffeine Intake during Simulated Team Sport Match-Play.

The aim of the current investigation was to identify the effects of scheduled carbohydrate (CHO) and caffeine (CAF) supplementation on simulated team sport match-play performance. Ten male hurling players completed three hurling match-play simulation protocols (HSP) performed 7 days apart in a double-blind, randomized design. Supplementation included CHO, CHO + CAF, and placebo (PLA). In a randomized order, participants ingested either a 6% CHO solution, a PLA solution of similar taste, or a combined intake of 6% CHO solution + 200 mg CAF capsule. At specific time points (Pre-0 min; half time (HT)-30 min; full time (FT)-60 min), participants completed a repeated sprint protocol (RAST; 12 × 20 m). Physiological [% maximal oxygen uptake (%VO2max), % mean oxygen uptake (%VO2mean), % maximal heart rate (%HRmax), % mean heart rate (%HRmean), respiratory exchange ratio (RER), and blood lactate (BLa)] and performance [(best sprint time (RSAbest), mean sprint time (RSAmean), and rate of perceived exertion (RPE)] variables were monitored throughout each simulation. Non-significant differences were observed between supplement trials (CHO, CHO + CAF, and PLA) for BLa (η2 = 0.001, small), %VO2max (η2 = 0.001, small), %VO2mean (η2 = 0.004, small), %HRmax (η2 = 0.007, small), %HRmean (η2 = 0.018, small), RER (η2 = 0.007, small), RPE (η2 = 0.007, small), and RSAbest (η2 = 0.050, small). RSAmean performance significantly improved in CHO + CAF trials compared to PLA, with sprint times significantly improved from Pre to FT also (η2 = 0.135, medium). A significant difference was observed in BLa between time points (Pre, HT, and FT) (η2 = 0.884, large) in % HRmax (η2 = 0.202, medium), %HRmean (η2 = 0.477, large), and RER (η2 = 0.554, large) across halves and in RPE across time points (η2 = 0.670, large). Our data provide novel data regarding the effects of CHO and CAF supplementation on team sport performance, with co-ingestion of CHO + CAF reducing the decrement in repeated sprint performance compared to PLA.

Stress and recovery perception, creatine kinase levels, and performance parameters of male volleyball athletes in a preseason for a championship

BackgroundTraining load and adequate recovery have been identified as essential elements to improve well-being and performance in team sports and avoid non-functional overreaching and overtraining.ObjectiveThis cohort study sought to analyze the stress and recovery perceptions, creatine kinase levels (CK), and vertical jump performance of volleyball athletes at different training times during a championship preseason.MethodsThirteen high-level male volleyball players (23.80 ± 5.40 years, 91.50 ± 8.80 kg, and 193.10 ± 6.40 cm) completed the RESTQ-Sport questionnaire on stress and recovery perception, and blood samples were collected to evaluate CK levels. These measures were performed six times over 16 weeks, while jumps such as squat jump (SJ), countermovement jump (CMJ), and countermovement jump arm (CMJA) were performed at three of those times for specific performance evaluation.ResultsThe stress perception and recovery perception indices increased and decreased, respectively, in the pre-competitive phase, while CK levels presented an initial rise, maintenance over the training period, and a drop. Vertical jump heights increased significantly throughout the preparatory period regardless of the type of jump. In all training phases, CMJA values exceeded CMJ and SJ values, and CMJ values exceeded SJ values.ConclusionsPositive adaptations were elicited by training stimuli, resulting in improvements in performance. Conversely, load training variables indicated higher levels of stress and muscle damage, together with lower perceptions of recovery during the championship preseason.

Effect of Individual Environmental Heat-Stress Variables on Training and Recovery in Professional Team Sport.

Exercise in hot environments increases body temperature and thermoregulatory strain. However, little is known regarding the magnitude of effect that ambient temperature (Ta), relative humidity (RH), and solar radiation individually have on team-sport athletes. To determine the effect of these individual heat-stress variables on team-sport training performance and recovery. Professional Australian Rules Football players (N = 45) undertook 8-wk preseason training producing a total of 579 outdoor field-based observations with Ta, RH, and solar radiation recorded at every training session. External load (distance covered, in m/min; percentage high-speed running [%HSR] >14.4km/h) was collected via a global positioning system. Internal load (ratings of perceived exertion and heart rate) and recovery (subjective ratings of well-being and heart-rate variability [root mean square of the successive differences]) were monitored throughout the training period. Mixed-effects linear models analyzed relationships between variables using standardized regression coefficients. Increased solar-radiation exposure was associated with reduced distance covered (-19.7m/min, P < .001), %HSR (-10%, P < .001) during training and rMSSD 48 h posttraining (-16.9ms, P = .019). Greater RH was associated with decreased %HSR (-3.4%, P = .010) but increased percentage duration >85% HRmax (3.9%, P < .001), ratings of perceived exertion (1.8AU, P < .001), and self-reported stress 24 h posttraining (-0.11AU, P = .002). In contrast, higher Ta was associated with increased distance covered (19.7m/min, P < .001) and %HSR (3.5%, P = .005). The authors show the importance of considering the individual factors contributing to thermal load in isolation for team-sport athletes and that solar radiation and RH reduce work capacity during team-sport training and have the potential to slow recovery between sessions.

Approaches to assessing the effectiveness of the team's performance in international athletics competitions (on the example of endurance)

The aim: theoretical substantiation and development of approaches to assessing the effectiveness of the results of the sports team's performance in international athletics competitions (on the example of endurance).&#x0D; Material and methods: theoretical analysis and generalization of scientific and methodological literature and information of the Internet, data of information databases of athletics (Tilastopaja), (All-Athletics), printed and electronic sources of the Association of Track &amp; Field Statisticians- ATFS ), the official website of the European Athletics Association (EAA), the Federation of Athletics of Ukraine, systematization, content analysis. An analysis of the results of competitive activities of athletes (n = 297) of the best thirteen European teams that participated in the XXIV European Athletics Championships (Berlin, 2018) in endurance and have gold awards. The criteria that allow to expand the approaches to assessing the effectiveness of the performance of the full team were considered.&#x0D; Results. The performance of thirteen best teams in athletics in endurance at the XXIV European Athletics Championships (Berlin, 2018) was analyzed. The obtained data allowed us to conclude that in order to create an objective assessment of the team's performance in athletics, it is not enough to take into account only the number of medals won and the places occupied by the team's athletes in the top eight. When determining the effectiveness of team performance in endurance classes, according to the existing evaluation system, medals were awarded to 2% to 33% of athletes from the total team, and places in the top eight were occupied by 18 to 75% of athletes.&#x0D; Conclusions. When evaluating the effectiveness of a sports team, you need to take into account a number of criteria that will create a diverse assessment of the performance of the sports team, which includes evaluation as a criterion - the performance of athletes at the level of personal achievement.

The influence of progressive-chronic and acute sodium bicarbonate supplementation on anaerobic power and specific performance in team sports: a randomized, double-blind, placebo-controlled crossover study

BackgroundThe aims of this study were to verify the effect of progressive-chronic and acute sodium bicarbonate (SB) supplementation on the anaerobic capacity, blood acid-base balance, and discipline-specific performance in team sports disciplines.MethodsTwenty-four trained male field hockey players completed a randomized, placebo-controlled, crossover trial of either progressive-chronic (increments from 0.05 up to 0.2 g/kg) or an acute one-off dose (0.2 g/kg) supplementation protocol. Before and after treatments, athletes completed an exercise protocol that comprised of a discipline-specific field performance test conducted between two separate Wingate anaerobic tests (WAnTs).ResultsProgressive-chronic SB supplementation improved anaerobic capacity in the first bout of WAnTs, as observed based on an increase in mean power (MP: 575 ± 71 vs. 602 ± 67 W, p = 0.005, ~ + 4.7%), peak power (PP: 749 ± 94 vs. 777 ± 96 W, p = 0.002, ~ + 3.7%), power carry threshold (PCT) at 97%PP (727 ± 91 vs. 753 ± 93 W, p = 0.002, ~ + 3.6%) and average power over PCT (739 ± 94 vs. 765 ± 95 W, p = 0.001, ~ + 3.5%). Acute SB supplementation had no effect on anaerobic capacity. However, an improvement in time during discipline-specific field performance test was observed after progressive-chronic (919 ± 42 vs. 912 ± 27 s, p = 0.05; ~ − 0.8%) and acute (939 ± 26 vs. 914 ± 22 s, p = 0.006, ~ 2.7%) SB supplementation. Acute SB supplementation also improved post-exercise parameters of acid-base balance (based on blood pH, bicarbonate concentration and base excess) compared to no supplementation or placebo.ConclusionsOur study indicates that both chronic and acute SB supplementation positively supports discipline-specific performance among field hockey athletes. Moreover, the chronic protocol supported anaerobic power indices before the inset of exercise-induced fatigue but had no significant impact afterwards. However, only the acute protocol significantly affected the buffering capacity, which can be used to determine athlete’s performance during high-intensity sporting events. This study design therefore highlighted that future studies focusing on sodium bicarbonate supplementation in team sports should concentrate on the efficiency of chronic and acute supplementation in varying time frames.

Team Achievement Goals and Sports Team Performance

This study focuses on team achievement goals and performance outcomes in interdependent sports teams. Team achievement goals reflect shared motivational states that exist exclusively at the team level. In a survey among 310 members of 29 premier-league field-hockey teams, team-level performance-approach, performance-avoidance, mastery-approach, and mastery-avoidance achievement goals explained 69% of the overall variance in team performance and 16% after controlling for previous performance. Teams performed better to the extent they were more approach- and less avoidance oriented in terms of both mastery and performance, although mastery-approach goals related to early-season team performance rather than predicting later changes in team performance.

The Flywheel Paradigm in Team Sports: A Soccer Approach

ABSTRACT Strength training is a key strategy to improve performance and injury prevention in team sports. Accordingly, several methods have been used, although because of the benefits reported after training based on eccentric contractions, the use of flywheel (FW) devices has extended within the periodization of strength training of team sports. However, nowadays, there is no clear consensus about the parameters used to optimize the training effects. This article examines the research behind these claims and attempts to draw evidence-based conclusions as to the practical implications for a precise use of FW with team-sport players, attending to their specific demands and objectives.

Inter-limb asymmetries are associated with decrements in physical performance in youth elite team sports athletes.

Actually, there is scarce literature looking for the relationship between inter-limb asymmetries and performance in youth elite team sports. The main purpose of this cross-sectional study was to examine the relationships between inter-limb asymmetries and physical performance in youth elite team-sports players. A secondary objective was to evaluate the presence of between-sexes differences in inter-limb asymmetries in elite youth team sports players. Eighty-one young elite team-sports athletes (age: u-14 to u-18) performed the star excursion balance test in the anterior direction (SEBT ANT), a single leg vertical countermovement jump test (SLCMJ), the one leg hop test for distance (OLHT), a 30 m sprint test, and the V-cut test. Inter-limb asymmetries were calculated for SEBT ANT, SLCMJ and OLHT. Pearson r was used to analyse the relationships between inter-limb asymmetries and physical performance. Results showed significant (p < 0.05) but small (r = 0.26) relationships between SLCMJ asymmetries and 30 m sprint time for the total group. Significant negative correlations with small to moderate magnitude of correlation were also found between SLCMJ asymmetries and SLCMJ performance on the lowest performing limb for the total group (p < 0.05; r = -0.26), males (p < 0.01; r = -0.48) and females (p < 0.05; r = -0.30). Moreover, significant negative correlations with moderate and large magnitude were also present between OLHT asymmetries and OLHT performance on the lowest performing limb for the total group (p < 0.01; r = -0.44), males (p < 0.01; r = -0.56) and females (p < 0.01; r = -0.64). No correlations were observed between asymmetries and either the V-cut test or SEBT ANT performance. No correlation were observed between SEBT ANT asymmetries and physical performance. In addition, when comparing asymmetry values between sexes there were no significant differences in vertical (p = 0.06) and horizontal (p = 0.61) jumping tests. However, there were significant differences in asymmetry between sexes in the ANT SEBT (p = 0.04). In conclusion, the current study indicated that jumping asymmetries were associated with decrements in sprint speed and jumping performance. Therefore, assessing inter-limb asymmetries would be recommended to improve training interventions for youth elite team-sports athletes.
