It was hypothesized that match demands would increase across all positional groups.Methods: Forty-two athletes from 1 AFLW club who played at least 1 match across seasons 6 to 8 (2022-2023) were included. Match-day running demands including total distance (TD), speed, acceleration, high-intensity running (HIR; >19 km/h), very HIR (VHIR; >21 km/h), and sprint distances (>24 km/h) were exported from Catapult Vector S7 global positioning system units. Raw speed (in meters per minute) and acceleration (in meters per second squared) files were exported to calculate 1-minute rolling peak periods. Linear mixed-effects regression models were conducted with effect sizes (d) to examine changes in match demands over time for the cohort and playing-position groups.Results: TD increased by 344 m (d = 0.33) between seasons 6 and 7 and 971 m (d = 0.72) between seasons 7 and 8 (P < .001). HIR, VHIR, rolling 1-minute peak speed, and acceleration increased between seasons 6 and 7 by 70 m (d = 0.38), 36 m (d = 0.31), 5.1 m/min (d = 0.15), and 0.04 m/s2 (d = 0.46), respectively (P < .001), while no changes were seen between seasons 7 and 8. Total player load increased by 28 AU (d = 0.29) between seasons 6 and 7 and 80 AU (d = 0.54) between seasons 7 and 8 (P < .001).Conclusions: TD increased across seasons 6 to 8, whereas HIR, VHIR, rolling 1-minute peak speed, and acceleration only increased between seasons 6 and 7. While changes in TD may encompass factors such as rule changes, relative metrics including HIR and VHIR changed in this cohort. These findings provide a comprehensive evaluation of current AFLW match demands and will assist in future AFLW athlete preparation.","PeriodicalId":14295,"journal":{"name":"International journal of sports physiology and performance","volume":" ","pages":"1-14"},"PeriodicalIF":3.5,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144475074","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}

Four measurement methods were used to determine MSS: 5-m split times over a 40-m sprint distance, 5-m splits over 30 m, 10-m split times over 40 m, and 10 -m splits over 30 m.Results: A repeated-measures analysis of variance revealed significant differences (P < .001) in MSS-derived differences from the different measurement methods with a ηp2 of .494 (large effect). MSS was significantly different between all methods (mean differences: 0.02-0.08 m·s-1; Cohen dz: 0.49-1.25). The greatest mean MSS was achieved using 5-m splits over 40 m. All MSS measurement methods had high relative and absolute reliability (intraclass correlation coefficient: .97-.98; coefficient of variations: 1.0%-1.2%; standard error of measurement: 0.07-0.08 m·s-1). There was a significant moderate positive correlation (ρ = .41) between MSS and acceleration distance.Conclusion: The highest estimate of MSS was found using 5-m splits over 40 m.

The data included information on session duration, intensity, and modality (eg, skating and classical skiing, roller skiing, running, cycling, kayaking, and others) and was separated into the general preparation (GP) and competition period (CP). Mode monotony was calculated as the proportion of the most applied mode.Results: Mean weekly mode monotony was 48.3% (4.3%) during GP and 55.0% (5.2%) during CP and correlated negatively with weekly training load (r = -.5, P < .001). The time gaps between sessions with the same mode (0 [same day]/1/2/3/4/5+ d) were distributed as 5/43/25/12/6/10% during GP and 5/47/21/12/11/15% during CP. During GP, 21% of intensive sessions were performed ≥14 days after the previous intensive session in the same mode, while the remaining sessions were spread evenly across 0 to 13 days, with each interval accounting for <10%. This trend reversed during CP, with 18% (6%) of intensive sessions (including races) in the same mode on consecutive days and other time gaps ≤11%.Conclusion: This study provides new insights into the day-to-day application of different exercise modes by world-class cross-country skiers. The findings indicate high variability in exercise modes, with mode monotony rarely exceeding 50%. While skiers frequently applied the same mode with gaps of 1 to 3 days, intensive sessions using the same mode were typically separated by longer intervals, except for gaps related to competitions.","PeriodicalId":14295,"journal":{"name":"International journal of sports physiology and performance","volume":" ","pages":"1-8"},"PeriodicalIF":3.5,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144333108","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}

The 8-week training (2 sessions/wk) consisted of 4 sets of back squats at 70% of 1-repetition maximum (1-RM) with 20% velocity loss. Pretesting and posttesting assessed ground-reaction forces during a single set of 10 repetitions at ~45% and ~70% 1-RM, performed with FW in one session and SM in another session.Results: Squat type (FW or SM) had minimal influence on longitudinal impulse, its components (mean force and time), or the angle of the resultant ground-reaction force. The only significant difference was observed in longitudinal impulse during the propulsive phase at ~70% 1-RM in the SM squat (P = .037), where the FW training group exhibited a reduction in longitudinal impulse posttraining, while the SM training group showed an increase.Conclusions: An 8-week squat training does not modify the effectiveness of force application, regardless of training or testing squat type. Therefore, both squat variations can be used interchangeably without systematically influencing the direction of force production, allowing athletes to select based on preference, equipment availability, or sport-specific demands.","PeriodicalId":14295,"journal":{"name":"International journal of sports physiology and performance","volume":" ","pages":"1-9"},"PeriodicalIF":3.5,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144333107","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}

Previous research highlights how the 100-m freestyle demands explosive power, technical proficiency, and tactical acumen, yet factors that distinguish world-class swimmers from their closely performing (inter)national-level counterparts remain elusive.Purpose: To identify race-performance factors differentiating world-class swimmers in the 100-m freestyle.Methods: World-best to national-level (N = 204) male swimmers competing at long-course events between 2019 and 2024 were analyzed using high-definition video and race-analysis software. Key performance metrics including stroke rate and length, turn efficiency, underwater phase duration, and velocity at 5-m intervals were extracted. Using a machine-learning random forest algorithm, the most salient factors distinguishing between world-class (0%-2.5% off world record), international-level (2.5%-5% off), and national-level (5%-10% off) performance categories were identified.Results: Analyses revealed a model classification accuracy of 89.5% with swim velocities at 65- to 70- and 70- to 75-m race segments most strongly associated with performance-level differentiation. These 2 race segments scored twice as high as all the other top 10 features. Shapley additive explanations (SHAP) analysis confirmed the importance of midrace velocities, while partial dependence plots identified the necessary velocity range values likely associated with national- to world-class performance levels.Conclusions: The combination of race analysis and machine learning creates the opportunity for targeted intervention for coaches and sport scientists working with high-performing 100-m male swimmers.","PeriodicalId":14295,"journal":{"name":"International journal of sports physiology and performance","volume":" ","pages":"1-9"},"PeriodicalIF":3.5,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144234045","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}

Players were further categorized as having \"full go\" (n = 15) or \"go as can\" (n = 12) participation status. The camp mean and coefficient of variation (CV) (indexing daily variation) for various workload parameters and resting heart rate and the natural log of the root mean square of successive differences (LnRMSSD) were quantified.Results: Skill players who consistently performed higher total workloads (total distance and player load) exhibited the most stable LnRMSSD (ie, lower CV; P < .05), while midskill players with the highest total workloads exhibited greater daily variation in LnRMSSD (ie, higher CV; P < .05). These associations persisted after injury-status adjustment. However, consistent between position groups, players with greater daily variation in select workload parameters also showed greater daily variation in LnRMSSD (P < .05). No between-groups differences for injury status were observed (P > .05), although effect-size analysis showed that LnRMSSD was moderately greater in \"full go\" players (effect size = 0.73, P < .07).Conclusions: Daily LnRMSSD variation better reflected position-specific workload responses, whereas mean LnRMSSD may affect or be affected by injury status. While skill players tolerated high total workloads with stable LnRMSSD, midskill players exhibited less day-to-day variation in LnRMSSD and high-intensity outputs at moderate workloads.","PeriodicalId":14295,"journal":{"name":"International journal of sports physiology and performance","volume":" ","pages":"1-8"},"PeriodicalIF":3.5,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144234044","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 commentary proposes a reframing of the interpretation of acceleration data and their use for athlete monitoring and exercise prescription. Although this applies to multiple sports, we will focus on the example of team sports in which these metrics are commonly used.Conclusion: Despite the recognized benefits of acceleration monitoring, 2 major limitations are evident. First, the common practice of classifying continuous acceleration data into discrete categories leads to a loss of relevant information, thus reducing the validity, reliability, and statistical power of analyses. Second, the use of arbitrary thresholds fails to account for individualized profiles, which are essential for monitoring. The limitations of these approaches are exacerbated by the lack of any objective justification for the thresholds used. We propose that acceleration be analyzed continuously, and, therefore, interpretation of data should be individualized. Accelerations should be analyzed as continuous variables rather than categorized into arbitrary thresholds. Individualized monitoring using players' maximum acceleration as a reference can provide a more accurate representation of players' physical demands.","PeriodicalId":14295,"journal":{"name":"International journal of sports physiology and performance","volume":" ","pages":"1-4"},"PeriodicalIF":3.5,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144003905","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}
