However, there is still great variety in the training and career development opportunities for novice and trainee sport scientists to develop their practice. The objective of this study is to audit current sports science professional standards worldwide. A network approach and modified scoping review protocol were used to guide a global search of existing national professional standards for inclusion in the audit. The professional standards from the included associations were analysed together to indicate the breadth and depth of their coverage, using thematic analyses and summary statistics. Professional standards from five countries were identified as meeting the criteria for inclusion in the audit. The standards from one country were selected as the basis for the standards audit. Five composite standard domains were created, with 37 related elements being included for comparison. Common elements exist across the audited sport science standards and there is inconsistent coverage of some elements. The findings are important for understanding the skill and competency expectations for sport science practice. This audit confirmed there is sufficient breadth, depth and international coverage to produce internationally representative professional standards in sport science.","PeriodicalId":17066,"journal":{"name":"Journal of Sports Sciences","volume":" ","pages":"2664-2671"},"PeriodicalIF":3.1,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148663955","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}

One hundred healthy adolescents completed isometric knee extension and flexion contractions on an isokinetic dynamometer, and an endurance task involving forty repetitions of maximal concentric-concentric knee extension and flexion contractions at 90°/s through an 85° range of motion. Peak torques were extracted from each limb and used to calculate hamstrings-quadriceps torque ratios and fatigue indices. Males exhibited a lower fatigue index than females for knee flexion and no difference for knee extension. Males showed higher isometric knee extension and flexion torques, higher isokinetic knee flexion torque at the end of the endurance task and higher knee extension torque at the start and end of the endurance task. Limb symmetry differences were also more evident during the endurance task compared to the isometric testing. These findings suggest that adolescent males and females exhibit distinct force generation abilities and that their sex-dependent endurance characteristics differ from those of adults. The inclusion of an endurance task in rehabilitation protocols may also provide additional insight that may not be evident via isometric testing.","PeriodicalId":17066,"journal":{"name":"Journal of Sports Sciences","volume":" ","pages":"2720-2728"},"PeriodicalIF":3.1,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148813278","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}

Relative theta, alpha, and beta power were calculated across six scalp regions of interest and analyzed using separate 2 × 6 × 3 mixed-design ANOVAs. Theta relative power showed significant main effects of group, region, and pass distance, with adolescents exhibiting higher overall theta activity than adults. Alpha relative power also showed significant main effects of group, region, and pass distance, whereas group-related interaction effects were not significant. Beta relative power showed a significant main effect of region and a group × region interaction, but no overall group or pass-distance effect. These findings indicate age-group differences in cortical oscillatory activity during soccer passing, expressed mainly in theta and alpha activity, whereas beta activity was more closely related to regional sensorimotor organization.

Since muscle activation correlates with muscle strength and performance, optimizing training variables to maximize activation during resistance training exercises is of interest. However, the most effective approach remains debated. This scoping review examines the impact of training variables such as intensity, range of motion (ROM), and repetition duration on muscle excitation, measured via surface electromyography (sEMG), in healthy, pain-free adults (≥18 years). Only original research in English was considered, focusing on acute bipolar sEMG assessments. A systematic search of PubMed, Scopus, and Web of Science identified 63 studies (35 on intensity, 13 on ROM, 15 on repetition duration) involving 966 participants. The findings indicate that higher training intensities generally produce greater sEMG signals. In addition, faster repetition durations are linked to increased muscle excitation, and greater ROM enhances excitation when repetition speed is controlled. However, when velocity is not standardized, ROM findings remain inconsistent. The current evidence suggests that higher intensity and faster repetitions increase muscle activation, while the effects of ROM remain unclear. Future research should focus on addressing these gaps and improving the experimental design to better understand the interplay of these training variables on muscle excitation.","PeriodicalId":17066,"journal":{"name":"Journal of Sports Sciences","volume":" ","pages":"2882-2906"},"PeriodicalIF":3.1,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148808815","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}

Stints were classified as Micro (<1 min), Short (1-3 min), Moderate (3-7 min) or Long (≥7 min). Stint architecture was stable across seasons; Moderate stints dominated and 34.7-38.2% of SEI variance was orthogonal to minutes. Matched player-games differed by roughly one-quarter to one-third in relative SEI. Fourth-quarter share was negatively associated with next-game unadjusted Player Efficiency Rating (uPER) change, reaching significance in 2025 and pooled but not in 2024; maximum consecutive Long-stint run was associated with non-appearance in 2025 but not in 2024.

Using a natural experiment design, we analyzed registry data spanning twelve years (excluding COVID-19 years), covering over 30,000 participants. Participation trends before and after the 2017 policy change were analyzed using GLMs and segmented regression, by gender and population proportion. Results revealed no significant level or trend changes in participation rates relative to the population after the removal of the LSPO. Girls' participation was stable across the study period, while boys showed a pre-existing upward trend that persisted after the rule change. These findings suggest that LSPO may not be a key factor associated with participation. Instead, existing trends and broader contextual factors likely play a more central role in shaping children's engagement in sport.","PeriodicalId":17066,"journal":{"name":"Journal of Sports Sciences","volume":" ","pages":"2709-2719"},"PeriodicalIF":3.1,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148673736","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}
