In many fields, including sport and exercise science, exploratory research is not openly reported, a practice that leads to serious problems. At the same time, exploration is a crucial step in scientific knowledge generation, and a substantial proportion of studies will be exploratory in nature, or include both confirmatory and exploratory analyses. Using a flowchart, we review how data are typically collected and used, and we distinguish exploratory from confirmatory studies by arguing that data-driven analyses, where the Type I and Type II error cannot be controlled, is what characterises exploratory research. We ask which factors increase the quality and value of exploratory analyses, and highlight large sample sizes, uncommon sample compositions, rigorous data collection, widely used measures, observing a logical and coherent pattern across multiple variables, and the potential for generating new research questions as the main factors. Finally, we provide guidelines for carrying out and transparently writing up an exploratory study.","PeriodicalId":17066,"journal":{"name":"Journal of Sports Sciences","volume":" ","pages":"1-13"},"PeriodicalIF":2.3,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143803568","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents a conceptual framework based on a review of existing motion capture methodologies, ranging from single-camera configurations to multi-camera systems enhanced with depth sensing and computer vision technology. The framework encompasses three distinct approaches: 1) single-camera with depth estimation, 2) single-camera with depth sensors, and 3) multiple cameras. Each method is detailed in terms of setup procedures, calibration techniques, advantages and disadvantages, as well as data processing workflows. The paper provides a framework and guide that can be adapted to different research and application contexts for sports and exercise, ensuring accurate and reliable 3D markerless motion capture. This framework aims to assist researchers, analysts and scientists in choosing the most suitable configuration based on their sport, specific requirements and/or constraints. By outlining the processes and considerations for each setup, this paper serves as a methodological guide, facilitating broader adoption and standardisation of advanced 3D motion capture technologies for sports and exercise. Although empirical data is not included in this paper, the focus on procedural guidelines demonstrates methodological rigour and practical implementation for 3D markerless motion capture research in sports and exercise.","PeriodicalId":17066,"journal":{"name":"Journal of Sports Sciences","volume":" ","pages":"1-8"},"PeriodicalIF":2.3,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143803639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to investigate the influence of contextual factors on efficiency and effectiveness across all English rugby union men's academies. Fourteen focus groups were conducted, one for each academy. Underpinned by pragmatic research philosophy, focus group discussions were analysed via reflexive thematic analysis. Analysis led to the generation of four themes to explain the impact of contextual factors: \"multiple loosely connected concurrent environments\", \"regulation drives practice\", \"organisational influences\" and \"searching for bang for buck\". Findings suggest complex interactions between a network of individuals and organisations, both internal and external to the structure of the talent system. In this context, it seemed inadequate to only consider the role of a single TDE. Overall, results reflect contextual and resource challenges constrain practice within English rugby union academies. In practice, we suggest the need to consider the tension of regulation to enhance minimum standards, against the increased autonomy that may result from flexibility of regulation to facilitate enhanced efficiency and effectiveness.","PeriodicalId":17066,"journal":{"name":"Journal of Sports Sciences","volume":" ","pages":"1-12"},"PeriodicalIF":2.3,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143795693","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among hip-based exercises, EMG amplitude was greater in BF during back extensions (SMD: 0.34, p = 0.0092), whereas EMG amplitude was greater in ST during kettlebell swings (SMD: -0.59, p = 0.0007).

Model performance was assessed using accuracy, precision, sensitivity, specificity, F1-score, AUC-ROC, and entropy, while Monte Carlo simulations ensured robustness across multiple iterations. Non-parametric statistical tests were employed due to the non-normal distribution of performance metrics, with the Friedman test revealing significant ranking variations among models. The results demonstrate that CAWNB consistently outperforms other models in terms of accuracy, precision, AUC, and F1-score, making it the most reliable choice for high-run chase prediction.

Most measured parameters recovered to baseline within 1 day, except concentric quadriceps peak torques and mean powers, which were restored within 2 days. By the second day, we also observed supercompensation in concentric hamstring and eccentric quadriceps peak torques and mean powers.

Yet, it is unclear how spatio-temporal, kinetic and kinetic asymmetries of wheelchair sprinting differ among wheelchair rugby players of different performance standard. The study purpose was to examine the associations between 30s sprint performances and spatio-temporal, kinetic and kinetic asymmetries on a dual-roller ergometer in elite and sub-elite wheelchair rugby players (n = 20). Kinetic differences between groups were investigated using statistical parametric mapping. Peak velocities were associated with the acceleration phase and higher peak power (r = 0.62, p = 0.003) and lower push times (r=-0.50, p = 0.020). Greater distance travelled during the acceleration phase were correlated with lower asymmetries in peak power (r=-0.58, p = 0.005). Overall, both peak velocity and total distance covered during the entire sprint was correlated with lower push times (r=-0.61, p = 0.003 and r=-0.62, p = 0.003) but greater peak power (r=-0.61, p = 0.003 and r=-0.62, p = 0.003). Elite players had lower power asymmetries between 1 to 15% and 95 to 100% of the push phase during the acceleration phase, accompanied by a lower initial contact asymmetry (p = 0.011). While power is an essential feature of sprinting, our findings show that how it is applied, in terms of asymmetry and coordination might differentiate the performance in wheelchair rugby.","PeriodicalId":17066,"journal":{"name":"Journal of Sports Sciences","volume":" ","pages":"1-7"},"PeriodicalIF":2.3,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143772605","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
