Therefore, this study aimed to analyze key performance indicators (KPIs) to provide the changes in these indicators over a decade spanning from 2011 to 2021. The sample included 45 (i.e. 100 sets; 957 games; 5743 points; and 54,918 shots) professional men's matches (Padel Pro Tour and World Padel Tour finals and semifinals) from three different sports seasons (2011, 2016, and 2021). KPIs related to time motion and technical and tactical analysis (i.e. unforced errors and winner shots) were examined. A series of linear mixed models was performed to investigate difference among competition years (2011, 2016, and 2021). Comparing the evolution of the game across the observed decade, it emerged a more progressive intense game (more explosive and rapid playing actions), decreasing number of shots per point (8.8 vs 9.5), and an increasing number of shots per minute (44.2 vs 40.0). Further, an increase in the importance of efficiency in overhead shots (unforced errors from bandeja/vibora +116% from 2011 to 2016) and responding to serve shots (unforced errors from serve return +17% from 2011 to 2021) emerged. Therefore, the present findings are able to highlight the evolution playing of professional padel (i.e. fewer shots per point, shorter effective playing time, decreased average point durations, higher number of shots per minute), thus providing references to potential valuable training plans.","PeriodicalId":47767,"journal":{"name":"International Journal of Sports Science & Coaching","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139956269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A pragmatic qualitative approach was used. Eighteen semi-structured interviews were performed. Thematic analysis was used to analyse the data. Three main law trial-related themes and four additional contextual themes were identified. The most important contextual factors include perceptions of resource scarcity of the implementation context, deficient concussion knowledge and lack of education among all stakeholder groups, tackle technique deficiencies, and an entrenched culture of a dismissive attitude towards serious injuries and non-disclosure of concussion by players. Real-world challenges such as inconsistent sanctioning during gameplay, multi-tackler tackles, and player fatigue underscore the gap between the theoretical knowledge of the law and the complex, dynamic nature of its execution. Furthermore, deeply ingrained issues like entrenched tackle techniques, the quality of coaching, and prevailing attitudes towards concussion compounded these challenges, indicating a need for a more comprehensive approach to bridge the divide between understanding and implementation. Despite these challenges, several participants felt the law variation was still more effective than the existing law; and that it created more awareness around concussion, while sending a clear message that player welfare is being taken seriously. Collectively these factors indicate the difficulty of addressing a complex problem such as concussion, with a law variation intervention in a challenging (resource-constrained) setting.","PeriodicalId":47767,"journal":{"name":"International Journal of Sports Science & Coaching","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139956165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study analyzed the accuracy and reliability of the PVL as a method to autoregulate the intraset repetitions using a moderate velocity loss (VL) threshold (15–30%).MethodsA total of 22 resistance-trained men were familiarized with the PVL in a single session. Test–retest was performed in two sessions 1 week apart, in which participants completed three sets of bench press and back squat at 40, 60, and 80% 1 repetition maximum (1RM). Participants stopped the sets when they reached a moderate VL zone using their PVL. Accuracy was assessed by analyzing whether the mean VL (actual) and the lower and upper limits of the confidence interval (CI) (95%) of each set were within the established VL range and quantifying the relative frequency of correctly interrupted sets. Test–retest reliability was examined by the intraclass correlation coefficient and coefficient of variation.ResultsPVL showed acceptable accuracy in both exercises at 60 and 80% 1RM (50–65% success rate) and retest for all loads (53–76% success rate). Similar PVL percentages were observed between most of the sets for the test and retest ( p > 0.05). Accuracy improved during the retest, especially for bench press (40% 1RM) and back squat (40 and 80% 1RM). PVL was not reliable in the test–retest comparison.ConclusionPVL can be a strategy with acceptable accuracy to autoregulate the intraset repetitions in a moderate zone (VL15–30%), but its reliability does not appear satisfactory after one familiarization session.","PeriodicalId":47767,"journal":{"name":"International Journal of Sports Science & Coaching","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139956148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It’s fast-growing popularity has been influenced by the contributions to competitors’ performance in mixed martial arts tournaments. This study aimed to analyze the frequency of actions, the transitions between them, and their reward–risk balance—the probability of submitting minus the probability of being submitted—among top-level competitors. Data encompassed all 93 matches (90 competitors) of the World Submission Fighting Championship-2019. Reliability was assessed by two experts (sports scientists, more than 10 years as no-gi Brazilian jiu-jitsu competitors). Data analyses used Bayesian methods for inference. Posterior distributions of the mean frequencies of actions indicate that the main actions (e.g. takedown, sweep, and back-take) tended to occur less than once per competitor in each match, except by the submission attempt (point estimate of 1.03 per match). The highest estimates for the transition probabilities between match actions were within-competitor—a guard pass action to another guard pass action (0.30); between-competitors—a takedown attempt to a submission attempt (0.15). Most of the actions presented positive reward-risk balance, particularly for the back-take, which showed the highest probability of direct transition to submission (0.45). The dynamic analysis of no-gi Brazilian jiu-jitsu matches evidenced some preferential actions’ transitions associated with winning. Findings should enhance the accuracy of performance prediction and provide evidence-based recommendations for coaches.","PeriodicalId":47767,"journal":{"name":"International Journal of Sports Science & Coaching","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135137788","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The variability in the analysis of the sample and distance covered may impede the application of the results in track and field athletes. The objective of this systematic review was to characterize the determinant biomechanical variables analyzed in the literature in each sprint phase. Four electronic databases were used (MEDLINE, Web of Science, SportDiscus, and Scopus). Only biomechanical studies with track and field athletes were selected. After the identification, screening, and eligibility process, 109 studies were included for qualitative synthesis and analyzed by the risk of bias assessment. The studies were classified in different sprint phases, according to the sprint task described by the authors (sprint start = 27, acceleration = 32, constant speed = 8, deceleration = 4, and not specified = 38). Factors such as the center of mass position, contact time, force applied on the rear block, and athletes’ ability to generate high amounts of force in the shortest possible time influence the sprint start performance. The acceleration phase is characterized by step frequency and step length transition, propulsive force, and minimization of braking force. Consequently, directing the resulting force as vertically as possible in the braking phase and as horizontally as possible in the anterior direction during the propulsive phase is important during the constant speed phase. In the deceleration phase, the decrease in step frequency and the increase in contact time may influence speed maintenance and, consequently, the result.","PeriodicalId":47767,"journal":{"name":"International Journal of Sports Science & Coaching","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135540479","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The kinematic variables of the spike performances were recorded using six optoelectronic cameras (Vicon Motion system, UK). Additionally, the wireless Trigno system (Delsys, USA) was used to record the electromyographic signals. The one-way ANOVA (1d SPM analysis) exhibited a significantly greater wrist internal rotation ( p < .001), wrist adduction velocity (p < .001), and palmaris longus activity ( p < .001) in the acceleration phase in U-20, compared to the U-16 group. Additionally, the U-20 and the U-18 players portrayed a significantly greater shoulder external rotation ( p < .001) and internal angular velocity ( p = .035) relative to the U-16 group. A significantly greater pectoralis major (p < .001), biceps brachii ( p < .001), and anterior deltoid ( p < .001) activity was observed in the U-20 group, compared to younger groups. This study suggests that older players employ more upper limb muscular activities during spike with the presence of blocks, which enables them to hit the ball with greater velocities and direct the ball in their desired direction through increased wrist ROMs.","PeriodicalId":47767,"journal":{"name":"International Journal of Sports Science & Coaching","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135539543","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The quality or efficiency of these decisions is bound by context-specific constraints on their decision-making. Artificial intelligence-based tools could alleviate some of these constraints. In Australian football, it is not yet known what these context-specific constraints are, nor is there any understanding of the thoughts and perception of elite Australian football coaches towards the use of artificial intelligence to support their decision-making. This study is the first to explore these issues in the context of elite Australian football and aims to inform the effective design and integration of tools to support the in-match decision-making of coaches in a manner that is welcomed by coaches. Using semi-structured interviews with elite Australian football coaches ( n = 6) and reflexive thematic analysis, two domains were explored: ‘barriers to decision-making’ and ‘thoughts and perceptions of a decision support system (DSS)’. Coaches discussed seven ‘cognitive’ and ‘environmental’ barriers, some of which may be addressed using artificial intelligence. Meanwhile, four themes were generated for the second domain, namely ‘willingness to adopt’, ‘expectation’, ‘concern and criticism’, and ‘DSS role’. The findings enable practitioners to design tools that are intended to address some of these barriers, while also providing insights into important considerations for the implementation and design of these tools that may increase the likelihood of achieving the endorsement of elite coaches and their support staff.","PeriodicalId":47767,"journal":{"name":"International Journal of Sports Science & Coaching","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135725968","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For athletes, optimizing sleep is becoming a popular strategy to enhance athletic performance. Athletes often complain of sleep problems including insufficient sleep and insomnia symptoms and are also at a higher risk for sleep disordered breathing. Sleep disorders and insufficient sleep can contribute to excessive sleepiness, daytime dysfunction, and performance problems. In contrast, better sleep provides benefits for physical health and athletic performance. For athletes, multiple factors can contribute to insufficient sleep. Sport-specific factors include frequent travel across time zones, competition and training schedules, high training loads, and sleeping in an unfamiliar environment. Non-sport-related factors include work, social, and family commitments; attitudes and sleeping beliefs; individual characteristics, such as chronotype or preference for morning or evening; and lifestyle choices. Fortunately, there are strategies that can be implemented to improve sleep in athletes including (a) education and emphasis on the importance of sleep; (b) sleep screening; providing extra sleep opportunities like (c) banking sleep and (d) napping; improving sleep hygiene like (e) proper light exposure; (f) a good pre-sleep routine; (g) a conducive sleep environment; (h) a strategy for supplementation; (i) utilizing circadian timing adjustments; and (j) jet lag management.
