In the arm-cranking test, oxygen uptake (V˙O2), heart rate (HR), and blood lactate concentration were determined to evaluate the maximum values of V˙O2 (V˙O2max) and HR (HRmax), their values at the lactate threshold (LT) (V˙O2LT and HRLT), as well as the onset of blood lactate accumulation (OBLA) (V˙O2OBLA and HROBLA).

Match running performance was monitored using 10-Hz global navigation satellite system units. Episode-level variables included HSR duration, recovery duration, HSR-recovery intervals, and intervals between consecutive HSR efforts. Linear mixed-effects models were used to compare playing roles, while recovery durations were categorized into <60 s, 60-120 s, and >120 s bands and analyzed using χ2 tests.Results: Mean HSR duration did not differ between starters and substitutes (2.37 [1.64] vs 2.40 [1.75] s), nor were differences for HSR-recovery intervals (3.86 [3.59] vs 3.75 [3.55] s), HSR-HSR intervals (3.51 [3.48] vs 3.57 [3.16] s), or the HSR/recovery ratio (1.05 [1.53] vs 1.00 [1.66]) (all P > .05).

Within 10 days, participants competed in the official HYROX Madrid 2025 event. Running speed was calculated for each of the eight 1-km segments and the Roxzone, as well as for the total running component, defined as the combined distance of run 1 to 8 and the Roxzone (8.70 km), and expressed in absolute terms (kilometers per hour) and relative to VT2 and vVO2max.Results: During laboratory testing, athletes reached a VO2max of 51.56 (5.00) mL·kg-1·min-1 (95% CI, 49.56 to 53.56), with VT2 and vVO2max occurring at 16.41 (0.87) km·h-1 (95% CI, 16.06 to 16.76), and 18.08 (0.81) km·h-1 (95% CI, 17.76 to 18.40), respectively.

However, little is known about current athlete monitoring practices and stakeholder perceptions in women's football. Therefore, this study aimed to examine monitoring practices and perceptions among (1) players and (2) coaching and performance staff to identify key facilitators and barriers to effective load management.Methods: All clubs from the Norwegian women's Premier League were invited to complete a role-specific online survey on data collection, data analysis, implementation, and evaluation of current monitoring practice. Eight clubs participated, eliciting data from 6 head coaches, 8 practitioners, and 113 players.Results: Five clubs (62.5%) reported systematic monitoring; all 5 included subjective measures, and 4 collected external loads, while 1 club measured counter movement jump test. Perceived individualization of training load (7-point Likert scale) yielded median scores of 5 and 6 for monitoring players and staff, respectively, compared with 4 and 2 for nonmonitoring players and staff. The most frequently reported challenges were \"players not responding\" for data collection, \"time constraints\" for data analysis, and \"lack of equipment\" and \"tactical considerations\" for decision on load adjustment.Conclusion: In this cohort, athlete monitoring was widely accepted but implemented heterogeneously and constrained by available resources. The findings generate the hypothesis that monitoring may increase perceived individualization of training, with good communication and visible use of data as potential facilitators. Future research should test this hypothesis in confirmatory studies and clarify the practical value of objective readiness measures for training-load decisions.","PeriodicalId":14295,"journal":{"name":"International journal of sports physiology and performance","volume":" ","pages":"1-8"},"PeriodicalIF":3.3,"publicationDate":"2026-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148891555","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 classified as starters (G1, >60 min), nonstarters (G2, 0 min), and nonstarters (G3, 1-30 min). External load metrics included total distance, high-speed running (HSR), and sprint distance, analyzed as both absolute values and relative values (% of total distance covered, and per minutes played). CT consisted of high-intensity interval exercise (∼925 m). Generalized estimating equations with least significant difference post hoc tests were applied (P < .05).Results: Significant group × intervention interactions were observed for HSR and sprint distance (P ≤ .002). Without CT, G1 showed higher HSR (585 vs 33-143 m) and sprint distance (115 vs 2-34 m) than G2 and G3 (P < .05). Following CT, both G2 and G3 markedly increased HSR (G2: 33→261 m; G3: 143→318 m; P ≤ .001), reducing differences versus G1. Sprint distance increased in G2 (2→75 m; P < .001), although G1 remained higher than G2 and G3 (P ≤ .05). Relative metrics confirmed these findings, with no between-group differences after CT.

Additionally, we characterized the temporal trends of dual participation (pool and open-water) to provide a necessary contextual framework for these competitive shifts.Methods: Involving data from 1066 individual performances, 1-dimensional statistical parametric mapping was applied to identify relevant tipping points in swimming velocity (v) between MED and NON-MED. Dual participation rates from 4 OG (2012-2024) and 7 WC (2013-2025) editions were evaluated using quadratic regression models.Results: Males MED progressively maintained higher v throughout races at the OG (2024: 1.47 m·s-1 for MED vs 1.41 m·s-1 for NON-MED) and WC (2025: 1.48 m·s-1 for MED vs 1.43 m·s-1 for NON-MED), reflecting an evolution toward sustained pacing. In women, pacing differences at the OG remained fragmented (2024: 1.31 vs 1.25 m·s-1), whereas WC data showed increasingly earlier and stronger dominance, culminating in full-race separation in 2025 (1.38 vs 1.33 m·s-1).

Current models outline the maximal oxygen uptake (V˙O2max), fractional utilization of V˙O2max (%V˙O2max) at lactate threshold (LT) or competition intensity, and gross mechanical efficiency or economy as key determinants of endurance performance. While the importance of V˙O2max and efficiency/economy has been confirmed repeatedly, less conclusive evidence has been presented on %V˙O2max. In this review, we provide a narrative overview of the current literature on %V˙O2max as one of the performance-determining variables in endurance sports, and whether it can be improved through training.Results: Out of the 35 studies assessing the relationship between %V˙O2max and performance, only a few studies confirm a substantial relationship between %V˙O2max and performance. This holds for %V˙O2max at a specific physiological \"landmark,\" such as LT and %V˙O2max at a competition-specific intensity. Additionally, there is limited evidence suggesting that %V˙O2max can be systematically altered through training in trained athletes. Methodological differences in the assessment of V˙O2max, LT, and endurance performance across the included studies, as well as variation in the training interventions, confound the interpretation of the findings.Conclusion: According to the current literature, %V˙O2max at LT or competition intensity does not seem to be a strong predictor of endurance performance. Practical recommendations on how to improve %V˙O2max via training can currently not be given. We encourage researchers to collect and publish data on %V˙O2max for a more comprehensive conclusion about its role for endurance performance.","PeriodicalId":14295,"journal":{"name":"International journal of sports physiology and performance","volume":" ","pages":"1-15"},"PeriodicalIF":3.3,"publicationDate":"2026-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148880002","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}
