Thirty-five male swimmers (age: 19.5 years ± 5.0, body mass: 75.4 ± 11.5 kg, body height: 181.7 ± 7.6 cm) performed a 15-s tethered-swimming test, in which peak force, mean force and impulse of each body side were measured. The absolute and relative asymmetries were subsequently obtained. The coefficient of variation was calculated and used to identify the presence of \"real\" asymmetries (i.e., asymmetries greater than the CV). The official times for 50-, 100-, and 200-m front-crawl swimming were obtained. Pearson's r correlations showed that peak and mean force presented moderate to strong associations (r = -0.51 to -0.84; p ≤ 0.001 to 0.013) with performance at all distances. Impulse only presented moderate associations with 50-m front crawl performance (r = -0.50 to -0.62; p ≤ 0.001 to 0.013). When considering the whole sample, no associations were seen between asymmetries and swimming performance, but when considering only athletes presenting \"real\" asymmetries, weak to moderate correlations were found between peak force asymmetries and 50/100-m performance (r = 0.47 and 0.59; p = 0.016 and 0.002). In conclusion, force and impulse are related to swimming performance, and individual asymmetries should be monitored in swimmers, as they might be present and related to performance depending on the approach adopted.","PeriodicalId":16055,"journal":{"name":"Journal of Human Kinetics","volume":"103 ","pages":"15-25"},"PeriodicalIF":4.0,"publicationDate":"2025-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13551352/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148911775","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to investigate the impact of lineup composition and game time on performance in men's WB at the Tokyo 2020 Paralympic Games. Through the analysis of 588 lineups from 42 matches, key game-related statistics (GRS) that differentiated winning from losing lineups were identified. Seventy different lineup types (LTs) were clustered and categorised based on players' functional classification (FC) and their performance across time windows was examined. Discriminant analysis revealed that field goal efficiency, assists, and minimising opponent assists were crucial for success, regardless of game balance, emphasising the importance of both offensive and defensive efficacy. Clustering categorised LTs into three distinct groups, with those featuring predominantly intermediate-point players (2.0-3.5) exhibiting superior performance, particularly during extended playing time (over 10 minutes), indicating a strategic advantage for these compositions in sustaining high-level play. Top-ranked teams typically showed greater roster depth and a wider variation of LT utilisation. This research highlights the significance of strategic lineup composition, emphasising the sustained effectiveness of lineups with intermediate FC players. The findings provide valuable insights for coaches, aiding in data-driven decisions for lineup selection, game strategy optimisation, and functional player development within the specific demands of WB.","PeriodicalId":16055,"journal":{"name":"Journal of Human Kinetics","volume":"103 ","pages":"277-288"},"PeriodicalIF":4.0,"publicationDate":"2025-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13551351/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148912381","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Twelve collegiate sprinters were randomly assigned to three conditions: control (CC), 90°IS condition (90°ISC), and 120°IS condition (120°ISC), using a balanced crossover design. EMG data from five lower limb muscles were collected during ISs, alongside the peak center of mass velocity (V peak), peak force (F peak), peak power (P peak), average power (P avg), and the force-velocity ratio at peak power (SFV) during subsequent SJs. Results showed that the 90°IS condition elicited higher rectus femoris (p = 0.035, d = 0.729) activation, while the 120°IS condition led to greater soleus (p = 0.030, d = 0.759), and tibialis anterior (p = 0.022, d = 0.812) activation. Both the 90°ISC and the 120°ISC significantly increased peak velocity (90°ISC: p < 0.001, d = 1.379; 120°ISC: p < 0.001, d = 0.979) compared to the CC, but showed no significant improvements in F peak or P peak. Notably, the SFV during the 90° and 120°SJ was significantly lower in the 90°ISC and the 120°ISC compared to the CC (90°ISC: p < 0.001, d = -2.658; 120°ISC: p < 0.001, d = -1.785). These findings suggest that the IS at different knee angles selectively activates lower limb muscles and enhances velocity-related performance metrics. Specific IS angles can alter the force-velocity relationship, increasing the velocity component at peak power during subsequent movements. Coaches and athletes in speed-dependent sports are encouraged to select IS angles tailored to their specific training goals and performance needs.","PeriodicalId":16055,"journal":{"name":"Journal of Human Kinetics","volume":"103 ","pages":"215-226"},"PeriodicalIF":4.0,"publicationDate":"2025-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13551340/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148911543","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Regarding the collective characteristics of soccer, it is important to observe the game in the same scale. In the coaching process, players' behavior can be constrained by coaches using feedback. This study aimed to investigate the role of feedback, performed by coaches, on the tactical behavior of soccer players. We searched in five databases: Scopus, Pubmed, Scielo, SportDiscus and Web of Science, following PRISMA-P guidelines. The PICOS strategy was used to establish eligibility criteria. Only quantitative studies written in English and published in peer reviewed journals were included. From the 1,149 articles found in the initial search, six were included in the review, and then were evaluated considering their methodological quality and risk of bias, through the quality index and the Joanna Briggs Institute (JBI) critical appraisal tools, respectively. Papers presented high heterogeneity regarding methods to apply feedback interventions and to assess the players' tactical behavior. Differences were observed in the task proposed to players, varying from small-sided games to official size games (3 vs. 3 to 11 vs. 11). Despite these differences, similarities could be found regarding the use of notational analysis in half of the papers, and analysis through positional data in the other half. The use of instructional constraints before the game seems to bring more clarity on how to better coordinate collective actions, causing a positive effect on players' tactical behavior.","PeriodicalId":16055,"journal":{"name":"Journal of Human Kinetics","volume":"100 ","pages":"293-308"},"PeriodicalIF":4.0,"publicationDate":"2025-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12946878/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147326225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Twenty-eight amateur ball players, with the mean age of 22.4 years old (SD = 1.9), were recruited and randomly assigned to either a simple or a complex visuomotor task intervention group, comprising bi-directional and multi-directional visuomotor training, respectively. Our study involved a four-week visuomotor agility training program. Visuomotor reaction times were recorded and analysed before and after the four-week intervention. The results demonstrated that both simple (F = 73.912; p < 0.01; ηp2 = 0.745) and complex (F = 80.6; p < 0.001; ηp2 = 0.762) visuomotor training were effective in enhancing participants' visuomotor performance at both levels of task complexity. The crossover effect of complex visuomotor training resulted in substantial improvement in both simple and complex visuomotor reaction time, suggesting that implementing complex visuomotor training could be more effective than a simple visuomotor training approach. These findings demonstrate the transferable effects associated with complex visuomotor agility training, highlighting its potential to enhance reactive agility across different levels of task complexity.","PeriodicalId":16055,"journal":{"name":"Journal of Human Kinetics","volume":"100 ","pages":"5-15"},"PeriodicalIF":4.0,"publicationDate":"2025-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12946877/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147326264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, there has been a significant increase in performance in the 400-m hurdles (mH) for both men and women. The main purpose of this study was to assess whether SF and SL were significant indicators of performance in the 400 mH. Additionally, the study sought to determine whether the ratio of stride length to stride frequency (SL/SF) could serve as a more effective performance indicator compared to analysing SL and SF separately. A total of 511 individual performances from four major championships (the World Championships Doha 2019 and Oregon 2022, the Tokyo 2020 Olympics and the Munich 2022 European Championships) were analysed through video during competition. SL showed high to moderate correlations with performance in both sexes, especially in the second half of the race. However, SF did not correlate with final performance and showed only minor differences between groups. Elite athletes demonstrated a higher SL/SF ratio, as well as greater SL, with more pronounced differences in the second half of the race. Coaches should consider using the SL/SF ratio rather than SF alone to enhance its validity as a kinematic variable related to performance. The current top athletes exhibit higher values for SL and the SL/SF ratio, with particular emphasis during the second half of the event.","PeriodicalId":16055,"journal":{"name":"Journal of Human Kinetics","volume":"103 ","pages":"185-200"},"PeriodicalIF":4.0,"publicationDate":"2025-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13551342/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148912438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
