      <content:encoded><![CDATA[Purpose: This study systematically reviewed the fatigue mechanisms that constrain trail running performance and examined the influence of sex and event distance on these responses. PRISMA guidelines were followed. PubMed, Web of Science, and Dimensions AI databases were searched up to August 10, 2025 for studies involving adult-trained or experienced trail runners that compared prerace and postrace fatigue markers after a standard trail race or laboratory race simulation. Risk of bias was assessed using the ROBINS-I. Twenty-four studies met the inclusion criteria (n = 674 subjects; 506 men and 168 women). Most studies (n = 21) examined only or predominantly male runners, and only four studies specifically assessed sex differences. Participants were trained adults (mean age = 39.4 [8.5] y), with sample sizes ranging from 6 to 72 individuals. Regarding race distance, 4 studies investigated short races (=60 km), 4 medium races (60-100 km), 8 long races (=100 km), and 8 compared multiple distances within the same study. Fatigue assessment primarily relied on knee extensor and plantar flexor torque testing to evaluate central and peripheral fatigue, complemented by alternative methods such as tensiomyography, soft tissue vibration, strength, and jump tests. Ten of the studies analyzed blood biomarkers related to muscle damage, inflammation, and renal function.

Conclusions: Neuromuscular fatigue in trail running arises from both central and peripheral mechanisms, depending on race duration and testing methods. While central fatigue predominates in shorter races, peripheral fatigue and muscle damage become more evident in longer events (=100 km). Moreover, sex differences are minimal, although methodological heterogeneity limits the strength and comparability of the findings.]]></content:encoded>

      <content:encoded><![CDATA[Purpose: The mechanisms behind improvements in running economy (RE) from shoes with supercritical foams (SCF) compared with a traditional midsole material (ethylene vinyl acetate [EVA]) remain only partially understood. This study aimed to evaluate the effect of midsole compliance and midsole resilience of different foams on RE, and spatiotemporal and perception outcomes.

Methods: To separate the effects of midsole compliance and midsole resilience, we compared 3 shoe conditions: EVA40, EVA35, and SCF35, where the number reflects the Asker C hardness, in 17 female runners in a randomized crossover experimental design.

Results: RE was similar between EVA40 (14.05 [1.25] W/kg) and EVA35 (14.02 [1.29] W/kg). RE in SCF35 (13.74 [1.22] W/kg) was better than in EVA40 (2.21%) and EVA35 (1.99%). Contact time was longer and step frequency was higher in SCF35, but these differences were small in magnitude. No significant difference was detected in comfort (P = .127) and perceived performance enhancement (P = .608).

Conclusion: Using EVA35 resulted in a more compliant shoe, with similar resilience compared to EVA40; however, this did not result in significant differences in RE, spatiotemporal, or perceived variables. SCF35 had a higher resilience than EVA35, as intended, but this was accompanied by increased compliance. It appears that the higher resilience in SCF35 condition was the main factor to improve RE compared with EVA conditions (1.99%-2.21%), as compliance differences between the EVA shoes did not affect RE (0.21%). Future studies should compare midsole materials with the same compression stiffness but different resiliency to further evaluate the importance of each characteristic in RE.]]></content:encoded>

      <content:encoded><![CDATA[Purpose: This study examined the associations between laboratory-based performance indicators and competitive success in elite cross-country skiing, considering sex- and age-related differences over a 15-year period.

Methods: A total of 106 Swiss National Team cross-country skiers (62 males and 44 females) underwent standardized physiological testing including 24-minute double-poling treadmill time-trial performance (24-minute DP), maximal oxygen uptake (VO2max), performance at the second lactate threshold, hemoglobin mass, 1-minute skating treadmill time-trial performance (Sprint1-min), squat jump peak power, and fat-free mass. Competitive performance was assessed using International Ski Federation (FIS) points in distance (FISDist) and sprint (FISSpr) events. Mixed-effects models analyzed the predictive strength of test variables, incorporating sex and age interactions.

Results: Twenty-four-minute DP and relative VO2max explained 42% of the variance in FISDist, while Sprint1-min (66%), squat jump, and absolute VO2max (both 50%) were the strongest predictors of FISSpr. Improvements in 24-minute DP, second lactate threshold, and Sprint1-min had a greater impact on reducing FIS points in females, whereas relative and absolute VO2max, hemoglobin mass, squat jump, and fat-free mass showed similar predictive relationships across sexes. Age moderated these associations, with younger athletes experiencing greater reductions in FIS points per unit increase in test performance.

Conclusions: This study highlights the importance of a comprehensive performance assessment in elite cross-country skiing that integrates ski-specific time trials, physiological capacity, strength, and body composition. The findings indicate that the relevance of laboratory-based performance indicators varies by sex and career stage, underscoring the need for longitudinal, age-aware interpretation when relating test outcomes to on-snow performance.]]></content:encoded>

      <content:encoded><![CDATA[Purpose: To investigate contributions of start, turn, and clean-swimming performance on total race time in top-elite junior and adult female swimmers.

Methods: A total of 681 long-course races from European junior and adult championships (50-1500 m including heats, semifinals, and finals) were video-analyzed.

Results: Start, turn, and clean-swimming performances showed a nonlinear development across race distances in both junior and adult swimmers. Start times progressively increased from 50 to 400 m and plateaued at 800 m. Turn times increased and clean-swimming speed decreased from 50 to 200 m and plateaued at 400 m. Clean-swimming speed showed the largest contribution to total race time. Start performance contributed most to sprint races, and the contribution of turn performance resembled an inverted U-shape, with highest contributions to 200- and 400-m races. Adult swimmers showed significantly faster start times over 50- (6.03%) to 200-m races (5.86%). Age-group differences in turn times were significant for 100 (4.92%) and 200 m (6.49%) but gradually declined over longer race distances. Clean-swimming speeds differed most over 50- (3.17%) and 100-m races (1.71%), with consistent but small differences for longer race distances (1.23%-1.34%). Percentile-based reference values were incorporated into a software-based tool that predicts and modulates total race time according to changes in start, turn, and clean-swimming performance.

Conclusions: The present findings help coaches identify individual swimmers` strengths and weaknesses and translate performance analysis data into targeted training and race strategies.]]></content:encoded>

      <content:encoded><![CDATA[Purpose: This exploratory study investigated the effects of a 3-minute re-warm-up protocol implemented during halftime on sprint and jump performance in female soccer players.

Methods: Twenty-two professional female soccer players from 2 Portuguese clubs from First and Second Divisions were randomly assigned to either a control group (G1: passive rest) or an experimental group (G2: re-warm-up). The Integrated Re-warm-up soccer protocol, performed by G2, consisted of 6 FIFA 11+ power exercises and a small-sided game. Performance was measured using a 20-m sprint and countermovement jump at baseline (post-warm-up) and after the half-time intervention. A 2-way analysis of variance (group × time) was conducted for analysis, with effect sizes reported as partial eta squared (n2p).

Results: A time × group interaction was found for sprint performance (F = 6.66, P = .019, n2p=.27), favoring the experimental group (G1: -0.25 s vs G2: -0.40 s). For countermovement jump performance, no time × group interaction was observed (F = 2.66, P = .483, n2p=.02), although a main effect of time effect was detected (F = 10.34, P = .005, n2p=.36); both groups showed a decrease in jump height, but to a lesser extent in the re-warm-up group (G1: -2.85 cm vs G2: -1.82 cm).

Conclusions: A brief 3-minute re-warm-up protocol implemented at halftime improved sprint performance compared to passive rest. These findings suggest that time-efficient re-warm-up protocols, combining FIFA 11+ power exercises and small-sided games may be useful during the half-time interval in female soccer players.]]></content:encoded>

      <content:encoded><![CDATA[Purpose: This study investigated the relationship between running power and VO2 across several submaximal incremental running speeds. Furthermore, it also determined whether the relationship between running power and VO2 changes after an endurance training period of 20 weeks, and, finally, the intrasubject differences of the relationship between VO2 and running power after the endurance training period.

Methods: Experiment I comprised 81 graded exercise tests from nationally trained runners (30 females and 51 males; 26.6 [7.0] y), and 18 (5 females and 13 males; 25.6 [5.2] y) were evaluated pretraining and posttraining (experiment II). Linear and multiple regression analyses were used to model the relationship between VO2 and running power.

Results: In experiment I, a strong correlation was observed between running power and VO2 (R2 = .88, P < .001). However, a multiple regression including heart rate, performance level, and sex revealed similar VO2 estimation (R2 = .89, P < .001). After 20 weeks of endurance training (experiment II), VO2 increased significantly (P < .001), while running power remained unchanged (P = .332). Additionally, individual regression analyses revealed significant changes in the slope and the intercept of the VO2-running power relationship.

Conclusion: Running power strongly correlates with VO2 but lacks sensitivity to detect metabolic adaptations after an endurance training period, as the metabolic demand changes for a given running power. These findings highlight the need for individualized and constant adaptation of the relationship between running power and VO2. Therefore, coaches should use running power as a complementary metric and periodically recalibrate individual power-VO2 relationships rather than relying on a fixed predictive equation for longitudinal monitoring.]]></content:encoded>

      <content:encoded><![CDATA[The COVID-19 pandemic of 2020 led governments around the world to respond by imposing lockdown restrictions, which limited the ability of cyclists to train and race as they typically would. While limited research describes the impact on professional and elite riders, less is known about the impact on recreational/sub-elite riders. Given that cyclists of this level contribute a high proportion of the cycling population, we set out to conduct a survey to determine the impact of COVID-19 on their training and racing practices. Questions covered their demographics and background, followed by their typical training, such as regular session type and frequency, training intensity distribution, and their racing practices. A total of 146 cyclists responded, and results revealed that despite decreases in the general population`s physical activity levels, 71.9% of respondents actually increased their cycling volume in 2020, with a significantly higher volume in every month in 2020 compared to 2019. Intensity distribution was also modified due to lockdowns, the volume of high intensity training was increased by 30.7% of respondents, while 37.3% decreased their high intensity training volume, often alongside an increase in overall volume. Racing practices were also altered, in-person racing dropped 56.6%, while e-racing on platforms such as Zwift increased by 114.7%. Despite the challenges, 67.9% of respondents reported feeling fitter in 2020, and 57.8% specifically felt the period of lockdown increased their fitness. These findings highlight the adaptability of recreational and sub-elite cyclists and their resilience to endure an unprecedented global pandemic.]]></content:encoded>

      <content:encoded><![CDATA[The pursuit of symmetry has long shaped discussions in sports science, particularly in sprinting, where every fraction of a second counts. Yet, the human body is inherently asymmetrical - our hearts are slightly left, most favour one hand or foot, and limb lengths or joint flexibilities are rarely identical. This begs the question: Why do we insist that symmetry is essential for peak sprint performance?
Asymmetry - differences in strength, flexibility, balance, and/or mechanics between body sides - is intrinsic to human movement. While marked and/or persistent asymmetries can disrupt biomechanics and increase (re)injury risk, minor bilateral differences are commonplace and often functional. For example, dominant limb strength allows for efficient movement patterns, even if it creates slight imbalances. Perhaps the relevant question then is not whether asymmetry exists but to what extent it affects human performance.
The relationship between asymmetry and sprint performance remains a subject of debate, with research often comparing kinematic and kinetic gait parameters across the left and right sides.1 While asymmetry has been a focus in recent research, significant gaps remain. Many studies have narrowly focused on the maximal speed phase,3,4 overlooking acceleration and deceleration. Additionally, research is predominantly centered on highly trained/national-level (Tier 3)5 and elite/international-level (Tiers)6 athletes, with limited data on World-class (Tier 5) sprinters.7 Sex-based differences also remain under-researched, as studies largely focus on male athletes.5,7
As our understanding of asymmetry in sprinting evolves, the conventional belief that an uneven stride slows a runner down prompts an important question: Does stride evenness truly matter for peak performance? This editorial contends that perfect symmetry is neither achievable nor necessary. Instead, the emphasis should shift towards identifying and addressing functional deficits to optimize sprinting mechanics, rather than forcing corrections that may disrupt natural biomechanics.]]></content:encoded>

      <content:encoded><![CDATA[This study aims to optimize the foot/pedal system ergonomics for world-class and elite international track cycling sprint specialists. Over the past decade, sprinters have been using custom-molded carbon shoes that do not adhere to any standardized optimization for the foot/pedal interface. The various foot-molding techniques used to date differ from one another and do not allow for the integration of orthopedic corrections. 70% of the French sprint team experienced non-traumatic lower limb injuries. The nature of these pathologies suggests the need for podiatric intervention, leading us to identify actual carbon-molded shoes as a potential cause. Currently, no studies have been conducted to validate any performance benefits of these custom-molded carbon shoes with orthopedic corrections for athletes. The challenges faced by elite sprint cyclists require optimizing power transfer between the rider and the bike while also preventing injuries due to the high levels of mechanical stress. The objective of our study was to determine whether the development of carbon-molded shoes with proper biomechanical consideration for each athlete could reduce the risk of injury and improve performance.]]></content:encoded>

      <content:encoded><![CDATA[As global temperatures rise and competitions increasingly take place in hot environments, understanding the impact of heat on performance is critical (Hunter et al., 2002). Thermal stress induces cardiovascular strain, alters brain activity, and modifies perceptual and motivational responses, affecting pacing and endurance (Périard et al., 2015). While studies have reported changes in heart rate (Girard & Racinais, 2014), muscle oxygenation, and cognitive function under heat (Nybo & Nielsen, 2001), few have focused on self-paced exercise. This study examines how heat affects performance, perceptual responses, motivation, and neural efficiency in trained cyclists during a simulated self-paced time trial.]]></content:encoded>

      <content:encoded><![CDATA[Social influence through verbal encouragement (VE) or non-verbal encouragement (NVE) aims to support athletes by mobilising resources. Its effectiveness has already been studied in sports by comparing performances with or without VE to investigate the performance-enhancing effect. However, these studies use standardised formulations, given at regular intervals by experimenters who are unknown to the participants, reducing the external validity. This may result in an underestimation of the actual effect. To date, no empirical evidence exists to characterise VE and NVE. The present study analyses the quantitative and qualitative characteristics of VE and NVE. We hypothesised that both would become more frequent the more demanding the task becomes. We video-recorded 39 Canadian hockey student-athletes (49% female, Mage = 20.97, SDage = 1.91). VE and NVE of the encouraging athletes on the sideline per second were coded, transcribed, and the content explored using deductive-inductive thematic analysis. We found that VE and NVE increased over time and that male and female athletes encouraged differently. Statements could be classified as informational, appraisal or tangible support. The results of the analysis can be used as a framework for naturalistic encouragement in future operationalisations. Moreover, we highlight the interpersonal differences in encouragement behaviour, specifically between men and women.]]></content:encoded>

      <content:encoded><![CDATA[This study examined whether match phase influences peak high-speed running distance (HSRD) and sprint distance (SpD) during 5-, 2- and 1-min peak periods and the subsequent post-peak periods. Match data from 480 Danish Superliga players were analysed in 9054-9671 full-time match observations across three seasons (2015/16, 2016/17, 2017/18) using Prozone tracking system and rolling averages methods. Peak periods of HSRD and SpD were much more frequent (P < 0.05) in the beginning of each half (21-28%), compared to the final 15-min periods of each half (5-11%). HSRD and SpD per min increased as peak period duration shortened (HSRD: ~23, ~39 and ~64 m/min for 5-, 2- and 1-min peaks, respectively; SpD: ~16, ~31 and ~54 m/min; P < 0.05), with no meaningful differences between 15-min intervals (P > 0.05). Recovery was faster (P < 0.05) following shorter peak durations and in the initial phase of the match, however differences in recovery kinetics were trivial to small beyond the first 15 min. Overall, players maintained similar HSRD and SpD in peak periods across all match phases. The post-peak declines were not systematically affected by the timing of the peak periods, but the decline was less affected in the initial phase, where the highest number of peak periods occurred.]]></content:encoded>

      <content:encoded><![CDATA[Skill acquisition is a rapidly evolving field in sport, but its definitions, roles and professional practices remain inconsistently articulated. Despite growing recognition of its importance, there is a lack of consensus regarding the core competencies and responsibilities of skill acquisition specialists. The aim of this study was to consult with experts to establish a consensus definition of the field of skill acquisition, clarify the roles of its specialists, and understand the needs and requirements of effective applied practice. A panel of 22 international experts in skill acquisition took part in a Delphi study using online surveys. The panel reached consensus that skill acquisition specialists represent a unique role within multidisciplinary support teams and defined the field as an applied science addressing the performance, learning, and refinement of perceptual, cognitive, and motor skills across the spectrum from novice to expert performers. Key responsibilities of a skill acquisition specialist included practice design, individualised skill development, and education at the organisational level. Furthermore, the panel reached consensus on the essential knowledge and professional skills required to fulfil this role effectively. Findings present an important step towards establishing a framework for professional development, accreditation, and high-quality, evidence-based skill acquisition practice.]]></content:encoded>

      <content:encoded><![CDATA[Surfing is increasing in popularity with rising professionalism in the sport. While sex-specific differences in skill, physical performance, and injury profiles are recognised across various sports, their presence in surfing remains unclear. This review collates the available evidence on sex-specific skill, physical performance, and injury profiles in surfers, to explore any evidence gaps and to recommend focus areas for future research. Five databases (Scopus, Web of Science, CINAHL Complete, SPORTDiscus, and MEDLINE Complete) were searched from inception to November 2025. Studies that investigated surfing skill, physical performance or injury profiles in both male and female participants were included. Of 4729 studies identified, 50 met the inclusion criteria. These included 10 studies on surfing skills, 17 on physical performance, and 32 on injury profiles. Studies included outcome measures with sex-specific comparisons for skill (70%), physical performance (64%) and injury (19%). Overall, sex comparisons were made consistently in five (14%) outcome measures across all study concepts. Limited research on sex-specific injury profiles restricts the development of injury prevention strategies for female surfers. As the literature evolves in surfing, researchers should maximise the value of their data by reporting on sex-specific differences, appropriately normalising values (where necessary) and utilising consistent testing approaches.]]></content:encoded>

      <content:encoded><![CDATA[A key facet of wheelchair basketball is the sport classification system, where players are assigned scores from 1.0 to 4.5 (where lower scores indicate greater activity limitation for wheelchair basketball related tasks), and on-court lineups cannot exceed a total of 14 sport classification points. In wheelchair basketball, the specific on-court roles of players are poorly understood outside of labelling players into sport classification categories or likening them to traditional running basketball positions. This study presents a data-driven approach to characterising playing positions in elite, male wheelchair basketball using Gaussian Mixture Model analysis. Box score metrics describing players on-court actions from 12 men`s international tournaments between 2019-2024 were analysed, totalling 5265 match statistics from 342 players across 304 matches. The model identified six novel and diverse player roles. These ranged from primary playmaker and dynamic impact roles that higher classification players (3.5-4.5) tended towards, to off-ball, defensive orientated roles which lower classification players (1.0-1.5) were frequently observed in. This research provides a novel framework for understanding player roles that accounts for the sport`s unique characteristics. This has significant implications for refining player selection in response to lineup needs, informing player recruitment for balanced team building and improving targeted player development pathways.]]></content:encoded>

      <content:encoded><![CDATA[The development of talent may take different forms for youth athletes, but there are only few longitudinal studies tracking this process. This study prospectively examines: 1) the development of talented Dutch tennis players aged 11.5 to 16 and 2) the predictability of performance at age 16, based on players` performance in preceding years. Biannually, we collected performance rating data of 1010 players (645 males, 365 females) who were ranked top 300 in the national youth ranking at least once. Applying Growth Mixture Modelling, we found that a 4-class model best fits the male sample, while a 5-class model fits the female sample most optimally. The best male class displayed non-linear development, improving slowly until age 13.5, after which development accelerated. The best female class showed consistent linear improvement. The correlation between performance at age 16 and preceding ages increased during adolescence. The correlation starts off moderate at slightly above 0.6 at age 11.5 and increases steadily to almost 1.0 at age 15.5. The correlation was consistently higher for the female sample. Our findings shed new light on male-female differences in talent development trajectories, and suggest that early talent identification could be more feasible for female players compared to male players.]]></content:encoded>

      <content:encoded><![CDATA[The purpose of this explorative study was to investigate the association between anatomic factors and risk for non-contact anterior cruciate ligament (ACL) injuries among female team sport players. A total of 225 players from basketball, floorball, and volleyball aged 12-38 years (median 16) participated in baseline physical examination including measurements of static knee and pelvic alignment, leg length, pelvic width, and femoral and tibial condyle widths. Players were then prospectively followed for new ACL injuries for 2.5-4.5 years. Legs were analyzed separately. After excluding eight players with a history of ACL injury, the final sample included 217 players and 434 legs. Associations between variables of interest and ACL injury risk were analyzed using generalized linear mixed models with binomial distribution and player and club as random effects. During the follow-up, 20 new non-contact ACL injuries were registered. None of the measures investigated showed a significant relationship with the risk of new non-contact ACL injuries. In conclusion, anatomic factors showed no association with increased risk of ACL injury in female team sport players.]]></content:encoded>

      <content:encoded><![CDATA[The so-called "torque training" has gained popularity among cyclists, but mixed evidence exists on its effectiveness. We analyzed the effects induced by torque training at two different pedaling intensities. During 10 weeks, 46 well-trained male cyclists (maximum oxygen uptake = 62.7 ± 5.8 mL·kg-1·min-1) were randomly allocated into a control group that kept their habitual cycling training (n = 15), or to two groups that added two weekly torque sessions performed with either a high relative load (HIGH-Load [n = 16], all-out pedaling cycles against 70% of the maximum dynamic force); or low relative load (LOW-Load [n = 15], 4-min intervals against 35% of the maximum dynamic force). Outcomes included performance indicators (i.e., maximum aerobic power [MAP], ventilatory thresholds, efficiency, time to exhaustion at the respiratory compensation point), body composition and quadriceps' morphological parameters. In within-group analyses, only HIGH-Load improved Wingate peak and mean power (p < 0.001), endurance indicators (MAP and ventilatory thresholds, p < 0.05) and quadriceps' cross-sectional area (p = 0.030). Larger improvements were observed for HIGH-Load compared to controls for Wingate peak and mean power and for quadriceps' CSA (all p < 0.01). In turn, no significant within-group differences were observed in LOW-Load, and between-group differences compared to controls were only found for Wingate mean power (p = 0.008). No significant differences were found between LOW and HIGH-Load despite moderate effect sizes for some outcomes (Cohen's d > 0.5 for MAP, Wingate performance and TTE). In summary, HIGH-Load torque training seems to improve different performance indicators and muscle morphology among well-trained cyclists, although its superiority compared to other torque training interventions should be confirmed in larger studies.]]></content:encoded>

      <content:encoded><![CDATA[Endurance performance determinants are typically assessed under fresh conditions, although physiological and mechanical characteristics deteriorate during prolonged exercise, a phenomenon recently termed durability or resilience. However, it is unclear whether durability and mechanisms underpinning it differ between sexes. Eleven females and 11 males matched for performance completed three laboratory visits including: a graded exercise test, a 12-min uphill time trial (TT), and a 180-min treadmill run at standardized moderate intensity, interspersed with repeated TTs every 60 min (total distance: 36 ± 3 and 42 ± 3 km, respectively). Physiological, biomechanical, and neuromuscular variables were assessed throughout the steady-state run and TTs and analyzed with linear mixed models. Time-trial performance declined during the run, with females displaying smaller speed decrements than males after 3 h (-1 vs. -10%, p < 0.01) and smaller reductions in carbohydrate oxidation and respiratory exchange ratio during steady-state (p < 0.05) and TTs (p < 0.01). Males displayed larger reductions in peak blood lactate during TTs (p < 0.001), while peak heart rate (HR) and oxygen uptake remained unchanged in both groups. During the prolonged run, females showed greater resilience for maximal isometric knee extensor force, HR, and perceived exertion (p < 0.05), whereas running economy deteriorated similarly between sexes. Biomechanical adjustments occurred in both sexes, with larger alterations observed in males for TTs (stride length; p < 0.05) and in females during steady-state (contact time and stiffness; p < 0.05). In conclusion, highly trained female runners demonstrate greater durability than performance-matched males. Sex differences are characterized by superior metabolic and neuromuscular resilience in females, whereas biomechanical changes appear similar between sexes. Finally, whether these findings persist under distance-matched conditions warrants investigation.]]></content:encoded>

      <content:encoded><![CDATA[This study investigated whether a six-week brain endurance training (BET) intervention could enhance soccer-specific performance and induce neural adaptations in structure-function coupling (SC-FC coupling) in sub-elite male soccer players. Seventy athletes competing in the regional first division and engaged in structured training 5-6 times per week were randomly assigned to a BET group (n = 35) or a control group (n = 35). Both groups continued regular field training, while the BET group additionally completed 24 cognitive sessions combining Stroop and dual n-back tasks. Resting-state fMRI and diffusion-weighted imaging were acquired before and after the intervention to assess SC-FC coupling across 246 brain regions using a multivariate prediction framework. Soccer performance tests included passing, shooting, agility, sprint, and aerobic capacity assessments. Compared with controls, BET participants demonstrated significant group × time interactions in passing accuracy, shooting precision, reactive agility, and sprint performance (all p < 0.05, n2p = 0.06-0.07). Specifically, LSPT completion time improved by 3.7%, LSST precision increased by 11.2%, and directional sprint times decreased by 5.1% following BET, with no change in the control group. Maximum running speed during the 30-15 Intermittent Fitness Test increased by 2.9% (p = 0.043, n2p = 0.07), whereas heart rate and blood lactate remained stable. MRI analyses revealed increased SC-FC coupling within executive and motor-related regions (e.g., DLPFC, IPL, caudate, Crus I) and decreased coupling within default mode and association areas (e.g., angular gyrus, pSTG; all p < 0.05, FDR-corrected). These coupling changes were significantly correlated with behavioral improvements, indicating that BET enhanced the neural efficiency of executive-motor networks. Overall, BET drives targeted neuroplasticity by strengthening the alignment between structural and functional brain systems that support attention, motor control, and fatigue regulation, translating into measurable gains in soccer-specific performance.]]></content:encoded>

      <content:encoded><![CDATA[Purpose: 

This study aimed to assess (1) the concurrent validity between critical power (CP) and the corrected power output at the respiratory compensation point (PORCP) and between W' and the quantity of energy depleted above PORCP (W'mod-SRS) in a modified Step-Ramp-Step (mod-SRS) protocol; (2) the test-retest reliability of endurance variables derived from a mod-SRS protocol.

Methods: 

Twelve trained male triathletes (31 ± 6 yr, 67.9 ± 7.1 mL min-1 kg-1) performed (1) an SRS protocol, (2) 4-5 severe-intensity constant work rate trials, (3) two mod-SRS protocols (test/retest), and (4) a heavy-intensity constant work rate trial. CP and W' were computed using a "best individual fit" approach. PORCP was corrected appropriately, while W'mod-SRS was computed as the energy depleted above PORCP. Test-retest reliability was assessed with the intraclass correlation coefficient (ICC), the standard error of measurement (SEM), and the coefficient of variation (CV%).

Results: 

CP was higher than PORCP in both trials (bias = 19 ± 19 W and 17 ± 20 W, P = 0.019 and 0.045). W' and W'mod-SRS were similar during both trials (bias = -2.8 ± 7.9 and -5.4 ± 8.8 kJ, P = 0.735 and 0.173). Test-retest reliability was moderate for W'mod-SRS (ICC = 0.66, SEM = 3.0 kJ, CV = 11.6%) and high for VO2peak, gas exchange threshold (GET), RCP, and their associated PO values (ICCs = 0.85-0.95, SEMs = 68-184 mL min-1, and 7-8 W, CVs = 2.1%-3.7%).

Conclusions: 

The mod-SRS protocol reliably measures VO2peak, gas exchange threshold, and RCP. Corrected PORCP systematically underestimated CP, which consequently impacts the computation of W' using a mod-SRS protocol. The design of the protocol may allow a more complete depletion of energy available above RCP while still eliciting VO2peak.]]></content:encoded>

      <content:encoded><![CDATA[Although transgender and gender diverse people make up 0.6% of the population in the United States, they are underrepresented in sports. Transgender athletes are increasingly visible and subject to widely discrepant policies regarding their participation in sports. This Contemporary Issues statement reviews topics relevant to the care of transgender athletes, for the providers, trainers, coaches, and others caring for this population. We review: 1) barriers to sport participation, 2) a review of gender-affirming medical and surgical care and the impacts on factors related to sport performance, 3) mental health considerations, and 4) a framework for understanding stressors and resilience. Most of the available data included here are from nonathlete transgender people, with limited data in transgender athletes. More robust data in transgender athletes are needed for future policies.]]></content:encoded>

      <content:encoded><![CDATA[Spielnahes Fußballtraining im Mädchen- und Frauenfußball ist eine umfassende Sammlung von Übungs- und Spielformen für eine moderne, altersgerechte Trainingsgestaltung - von der U12 bis in den Übergangsbereich des Frauenfußballs. Die Trainingsinhalte wurden in der Frauenfußball-Akademie der Universität Würzburg nach neuesten wissenschaftlichen Kenntnissen entwickelt und sind seit über einem Jahrzehnt praxiserprobt.

Das Buch bietet einen tiefgehenden Einblick in die Besonderheiten des Trainings mit Juniorinnen und Frauen. Körperliche, psychische und soziale Unterschiede werden ebenso thematisiert wie entwicklungspsychologische Grundlagen und die besondere Rolle der Leistungsmotivation. Die Trainingsphilosophie basiert auf dem spielnahen Ansatz der von der Frauenfußball-Akademie entwickelten GOAL-Philosophie und ist so konzipiert, dass sie in variablen Trainingsformen jederzeit an die Bedürfnisse der Trainerinnen angepasst werden können. Die Anwendung aller Übungen gelingt mit geringem Materialaufwand und minimalem Umbau zwischen den Trainingsphasen. Der SCORE-Court als zentrales Gestaltungselement des Trainings wird praxisnah erklärt - inklusive seiner verschiedenen Formen, Umbaumöglichkeiten und der Übertragbarkeit auf das Wettkampfspiel.

Trainer:innen erwartet ein Buch, das fundiertes Wissen mit hoher praktischer Relevanz verbindet. Didaktische Prinzipien, clevere Provokationsregeln, taktische Spielformen und eine klare Struktur helfen, das Training abwechslungsreich, zielgerichtet und entwicklungsorientiert zu gestalten. Ein Buch für alle, die Mädchen und Frauen im Fußball nicht nur trainieren, sondern gezielt fördern wollen. Klappentext]]></content:encoded>

      <content:encoded><![CDATA[Die internationalen Entwicklungen im Olympischen Triathlon zeigen, dass die Grundsteine für Erfolge und vordere Platzierungen in der ersten Teildisziplin "Schwimmen" gelegt werden. Während auf dem Rad und beim Laufen insbesondere durch den Einsatz von "Powermetern" und Herzfrequenzsensoren die Belastung und die Beanspruchung der Athletinnen und Athleten objektivierbar sind, fehlen im Schwimmen - vor allem im Freiwasser -  derzeit noch objektive Daten (z. B. geschwommene Schwimmwege und -geschwindigkeitsverläufe). Allein aus der Gesamtzeit und der offiziellen Angabe zur Distanz der Strecke lassen sich kaum relevanten Informationen ziehen. Daher wird während des Wettkampfs (Freiwasser) das Schwimmen mittels mehrerer hochauflösenden Kameras untersucht. Diese Kameras decken die Schwimmstrecke ab und müssen kalibriert werden (Test und Vergleich von verschiedenen Methoden: Vermessung fester Punkte, Schachbrett- oder Stab-Kalibrierung). Durch das Tracking der Badekappen (anfangs manuelles Tracking, später Anlernen und Nutzung von neuronalen Netzen) sollen im Wettkampf die individuellen Schwimmwege und -geschwindigkeiten der einzelnen Schwimmerinnen bzw. Schwimmer verfolgt und analysiert werden. Der Einsatz dieser videographischen Methode erlaubt zusätzlich auch die Analyse von ausländischen Athletinnen und Athleten und soll perspektivisch auch zur Gegneranalyse genutzt werden.]]></content:encoded>

      <content:encoded><![CDATA[Coaching im Leistungssport hat sich in den letzten Jahren zu einem zentralen Bestandteil der Trainerarbeit entwickelt. Während der Begriff "Trainer" traditionell mit der fachlichen Planung und Steuerung von Training assoziiert wird, umfasst Coaching ein breiteres Spektrum: die individuelle Unterstützung, Reflexion und Begleitung von Athletinnen, Athleten und Trainerkollegen. Der vorliegende Beitrag beschreibt die Entwicklung und Implementierung eines modernen Coachingverständnisses in der Deutschen Triathlon Union (DTU) unter Berücksichtigung des Rollenmodells nach Weiand (2022). Es werden die theoretischen Grundlagen, die praktische Umsetzung in der DTU-Steuerungsstruktur sowie Erfahrungen aus der Athleten- und Trainerausbildung dargestellt.]]></content:encoded>

      <content:encoded><![CDATA[Der Leistungssport ist ein Handlungsfeld, in dem Entscheidungen unter Bedingungen hoher Unsicherheit getroffen werden müssen. Trainingsplanung, Trainingssteuerung und langfristige Entwicklungsprozesse erfolgen in einem Kontext, der durch individuelle Reaktionsmuster, wechselnde Rahmenbedingungen und eine Vielzahl kaum kontrollierbarer Einflussfaktoren geprägt ist. Gleichzeitig besteht ein hoher Anspruch an Rationalität, Nachvollziehbarkeit und wissenschaftliche Fundierung. Training soll evidenzbasiert sein, Entscheidungen sollen begründet, Entwicklungen erklärbar werden. Diese Spannung zwischen Erkenntnisanspruch und Praxisrealität bildet den Ausgangspunkt dieses Beitrags. In den vergangenen Jahrzehnten hat sich der Diskurs im Leistungssport zunehmend zugunsten empirischer Evidenz verschoben. Trainingswissenschaftliche Studien, Metaanalysen und systematische Reviews gelten als zentrale Referenzpunkte professionellen Handelns. Diese Entwicklung ist grundsätzlich zu begrüßen. Sie hat dazu beigetragen, vereinfachende Annahmen zu hinterfragen, methodische Standards zu etablieren und die Qualität sportwissenschaftlicher Argumentation zu erhöhen. Zugleich zeigt sich jedoch eine wachsende Diskrepanz zwischen dem Anspruch wissenschaftlicher Steuerbarkeit und der erlebten Realität des Trainingsalltags. Trainerinnen und Trainer berichten übereinstimmend, dass Trainingsprozesse selten den prognostizierten Verläufen folgen, dass identische Belastungen zu unterschiedlichen Anpassungen führen und dass relevante Entscheidungen häufig unter Bedingungen getroffen werden müssen, die empirisch nur unzureichend abgebildet sind.
Diese Diskrepanz ist kein Zufall und kein Ausdruck mangelhafter Wissenschaft oder unzureichender Praxis. Sie verweist vielmehr auf ein grundlegendes epistemisches Problem: Trainingsprozesse im Leistungssport werden zu häufig als lineare, mechanistische Systeme gedacht, obwohl sie in Wirklichkeit hochkomplexe, offene und dynamische Anpassungsprozesse darstellen. Eine solche Fehldeutung führt zwangsläufig zu überhöhten Erwartungen an Wissenschaft, zu einer problematischen Delegation von Verantwortung und zu einer Unterschätzung erfahrungsbasierter Kompetenz. Um das Verhältnis von Empirie und Intuition angemessen zu bestimmen, ist daher zunächst zu klären, was Training als Gegenstand einer angewandten Wissenschaft bedeutet - und welche Art von Wissen im Leistungssport tatsächlich handlungsfähig macht.]]></content:encoded>

      <content:encoded><![CDATA[Concurrent training (CT) ist definiert als die simultane oder sequenzielle Integration von Kraft- und Ausdauertraining innerhalb eines periodisierten Trainingsprogramms. Dies ist gerade im Triathlon von besonderer Relevanz, da die Sportart selbst eine Kombination dreier Ausdauerdisziplinen darstellt. Trotz dieser Ausdauer-Dominanz und des hochvolumigen aeroben Trainingsumfangs, welches den Triathlonsport typischerweise charakterisiert, zeigen zahlreiche Studien, dass eine regelmäßige Implementierung von Krafttraining in das Trainingsprogramm die Leistungsfähigkeit von Triathleten in allen drei Disziplinen signifikant verbessern kann. Vor diesem Hintergrund adressiert dieses Manuskript in Kürze die folgenden zentralen Aspekte: (i) historischer
Hintergrund des CT, (ii) grundlegende molekulare Grundlagen der Anpassung an Kraft- und Ausdauertraining, (iii) die Problematik des Interferenzeffektes, (iv) modifizierbare und nicht-modifizierbare Variablen des Interferenzeffektes (v) praktische Handlungsempfehlungen für das Triathlontraining.]]></content:encoded>

      <content:encoded><![CDATA[Gesundheitsmonitoring im Spitzensport beschreibt die systematische, fortlaufende Erfassung und Analyse gesundheitsrelevanter Zustands- und Verlaufsdaten mit präventiv-medizinischer Zielsetzung. Insbesondere in Ausdauersportarten treten gesundheitliche Einschränkungen häufig als kumulatives Belastungsgeschehen über den Saisonverlauf auf. Im Triathlon dominieren dabei Überlastungsbeschwerden und krankheitsbedingte Leistungseinschränkungen. Daraus ergibt sich die Notwendigkeit longitudinaler Monitoringdaten, um Warnzeichen (z. B. zunehmende Ermüdung, reduzierte Belastungsverträglichkeit, funktionelle Beschwerden) frühzeitig zu erkennen und daraus individuelle Maßnahmen für Regeneration, Rehabilitation und Belastungssteuerung abzuleiten. Methodisch wird Gesundheitsmonitoring als multivariater Ansatz verstanden, der physiologische Marker, subjektive Selbstberichte, medizinische Überwachung (Verletzungen/Erkrankungen/Ausfallzeiten) sowie ergänzende funktionelle Diagnostik bestmöglich integriert. Am Beispiel des Deutschen Skiverbands wird die Implementierung des online-basierten Athletenmanagementsystems Smartabase dargestellt, das seit 2020 schrittweise eingeführt und seit Mai 2023 in Biathlon und Skilanglauf genutzt wird. Der Beitrag zeigt, wie disziplinspezifische Erhebungsstrukturen, standardisierte Kodierungen und integrierte Dokumentationsprozesse die interdisziplinäre Betreuung und die Ableitung individueller gesundheitsbezogener Maßnahmen unterstützen können. Zudem werden zentrale Anforderungen und Grenzen des Ansatzes hinsichtlich Interpretationssicherheit, Validität, Akzeptanz, Ressourcen sowie Datenschutz und Ethik diskutiert.]]></content:encoded>

      <content:encoded><![CDATA[This study quantified and compared session and drill-specific physical characteristics between U10, U12, U14 and U16 youth women`s footballers. Data were collected during 80 training sessions using 10 Hz GPS, totalling 825 training observations and 2298 drill-specific observations from 116 players representing two of the English Football Association`s Emerging Talent Centres. Linear mixed modelling estimated session and drill-specific; total distance (TD), high-speed running (HSR; >3.00 m · s-1), very high-speed running (VHSR; >4.83 m · s-1) and sprinting (SPR; >5.76 m · s-1) distances (m), maximum velocity (m · s-1) and number of accelerations and decelerations (>1 m · s-2, >2 m · s-2, >3 m · s-2). During sessions, U16s covered more TD than U14s, whilst both U14s and U16s covered greater HSR, VHSR and SPR distances compared to U10s and U12s, and U10s performed more accelerations (>1 m · s-2) than U12s and U14s and more decelerations (>1 m · s-2) than all other age groups. All age groups had higher physical outputs during SSGs compared to possession and technical drills. Differences in session physical characteristics observed between age groups and between and within age groups for drill-specific physical characteristics, highlight that physical characteristics during training are age- and drill-dependent within youth women`s football. These findings have practical implications for informing coaching and talent development practices within youth women`s football.]]></content:encoded>

Thirty participants were allocated to SS (n = 15) or CL (n = 15) and completed a 6-week full-body resistance training program. Both groups trained squat (SQ) and bench press (BP) with matched volume (18 repetitions per exercise per session) and intensity (75% 1RM). SS alternated SQ and BP with 1-min between exercises and 3-min between supersets; CL inserted 30-s intra-set rests every two reps, used 3-min between sets, and completed all SQ before BP. Pre- and post-tests assessed countermovement jump (CMJ) height, medicine-ball throw (MBT) distance, and load - velocity (L - v) parameters - load-axis intercept (L0), velocity-axis intercept (v0), and area under the L - v relationship line (Aline) - for SQ and BP. Time effects showed significant improvements in CMJ, MBT, L0, and Aline in both groups, whereas v0 did not change (p = 0.627). No time×group interactions were detected (p = 0.085). Between-group differences were trivial, with small non-significant effects favouring SS for SQ v0 (ES = 0.44) and CL for BP Aline (ES = 0.28). Supersets achieved comparable adaptations with substantially shorter rest time (9 vs. 23 min), supporting their use as a time-efficient training strategy.]]></content:encoded>

      <content:encoded><![CDATA[This systematic review aimed to evaluate the effects of resisted sprint and plyometric training on change-of-direction (CoD) performance across populations ranging from recreationally active adults to athletes. We searched PubMed, Google Scholar, SPORTDiscus, Scopus, and Web of Science up to June 2024, and included 21 randomized controlled trails (30 intervention groups) comparing resisted modalities against active and passive controls. A multilevel random-effects model using standardized mean differences (SMD) revealed a significant pooled effect (SMD = -0.24, p = 0.005). Subgroup and moderator analyses showed that adolescents exhibited greater improvements in CoD performance compared to adults (SMD = -0.42, p < 0.01), and elite athletes demonstrated larger gains compared to recreational active individuals (SMD = -0.43, p < 0.01). Among training modalities, resisted linear sprinting demonstrated consistent CoD benefits (SMD = -0.29, p < 0.01). Additionally, low-frequency training (SMD = -0.32), relative load (SMD = -0.22), and auto-regulated load (SMD = -0.53) were associated with enhanced CoD speed (all p < 0.05). These findings suggest that resisted training significantly improves CoD ability, particularly among adolescents and elite athletes. Optimizing training parameters, including load prescription, frequency, and resistive type, may effectively enhance CoD outcomes.]]></content:encoded>

      <content:encoded><![CDATA[The purpose of this exploratory data analysis was to identify performance predictors of the bobsleigh push phase and to evaluate their importance and effect on performance. Fifty-three predictor variables were derived from a large dataset containing kinematic and joint kinetic variables of 305 ground contact phases (GC) of 28 male elite bobsleigh athletes, which were input to a Random Forest regressor (RF) to predict average forward acceleration. The push phase was divided into a start acceleration (SAP1: first GC after the push-off from the start-block; SAP2: second GC) and acceleration phase (AP: GC at 10 m) to account for phase-specific differences. Recursive feature elimination was employed to increase model accuracy and reduce complexity. Predictor importance measures (IMP) were quantified as the mean change in test error. The RF consistently performed well in explaining differences in acceleration (SAP1: 67%, SAP2: 60%, AP: 60%). The angle of attack was ranked as the top performance predictor across the push phases (IMP: 0.75-1.1) highlighting the importance of whole-body forward orientation for acceleration. The hip angular impulse was positively associated with performance during SAP1 (IMP: 0.4) and SAP2 (IMP: 0.5), which accentuates the importance of strong hip extensors for resisted acceleration.]]></content:encoded>

      <content:encoded><![CDATA[Background: Recent research findings suggest that a daily diet containing low carbohydrate (LCHO) consumption coupled with low energy availability (LEA, specifically what is termed problematic LEA [P-LEA]) exacerbates the risk of developing relative energy deficiency in sport (REDs). Regrettably, research evidence also indicates that dietary carbohydrates are likely underconsumed by many athletes in their daily diets. How these factors, P-LEA and LCHO intake, interact to precipitate the amplification of REDs risk is currently not entirely clear and is the source of much speculation. Purpose: As such, we present herein a hypothetical model of how LCHO dietary intake and P-LEA exposure can interact to create an amplification of the endocrine disruptions associated with REDs, specifically via the development of a low triiodothyronine (T3) state, clinically referred to as low T3 syndrome. The hypothesis presented postulates that P-LEA + LCHO interact to promote reductions in T3 levels in part by inducing a greater cortisol response (at rest or exercise), which in turn inhibits the endocrine function involving the production of T3, as well as the conversion of thyroxine to T3. The resultant low T3 state in turn amplifies the negative hormonal consequences associated with REDs (eg, reduced reproductive, anabolic, and metabolic hormone levels). Conclusions: Practically speaking, athletes and their coaches must recognize the importance of carbohydrates in the diet, specifically the amounts and the timing of their consumption; strive to avoid P-LEA exposure; and monitor for REDs indicators (eg, T3). Researchers are encouraged to pursue investigations to challenge and evaluate our proposed hypothesis concerning how low T3 is the critical factor in the negative hormonal consequences of REDs and the role cortisol plays in these outcomes.]]></content:encoded>

      <content:encoded><![CDATA[For many athletes, being agile is the end goal of physical performance training. It represents their capacity to change velocity and direction in response to the actions of their opponent and the opportunities and constraints of their environment. The aim of this article was to describe the pitch-based development of agility, focusing on 60-180° turns. This ensures all turns have the demand of deceleration, turning, and reacceleration, requiring both outside leg turns (60°) and inside leg turns (180°). To enable the effective coaching of these, coaches must understand movement mechanics and thus the fundamental principles that underpin good technique. Within agility training, a detailed appreciation of how the center of mass and base of support interact to affect the direction of force is fundamental to this. This understanding and the ensuing technical models ensure athletes have the best chance of executing the task optimally and ensure coaches can effectively instruct athletes and adapt drills accordingly.]]></content:encoded>

      <content:encoded><![CDATA[Abstract
Purpose: 
The cerebellum is essential for motor control due to its dynamic interactions with the sensorimotor network (SMN). Within the cerebellum, motor functions are organized into two distinct representations, known as the first motor representation (MRP1) and the second motor representation (MRP2). While long-term training in athletes optimizes motor control, the functional reorganization in the cerebellum and its interaction with the SMN remains unclear. Specifically, the unique contributions of MRP1 and MRP2 to motor expertise remain poorly understood.

Methods: 
We utilized task-based functional magnetic resonance imaging and dynamic causal modeling to compare 55 elite basketball athletes with 65 nonathlete controls during two general motor tasks: a grip force task focused on upper-limb control and a leg raise task assessing lower-limb postural control. We examined brain activation and effective connectivity across cerebellar and cortical motor regions.

Results: 
No significant differences in regional brain activation were found between the groups. Dynamic causal modeling analysis revealed that, compared with nonathletes, athletes` MRP1 showed a significant stronger bidirectional connectivity with effector regions in both tasks. In contrast, athletes` MRP2 exhibited a significant decreased connectivity with effector regions during the leg raise task. Additionally, there was a nonsignificant trend toward increased connectivity from MRP2 to the motor planning regions of SMN in athletes.

Conclusions: 
Our findings suggest that the neural signature of expert motor control is better reflected by refined interactions within the cerebello-cerebral circuit, rather than by heightened neural activation. Athletes demonstrate a reorganization of cerebellar modulation, with MRP1 facilitating automatic motor output and MRP2 showing reduced involvement during complex tasks. These results provide new insights into the neural basis of motor expertise and could inform targeted approaches in sports training and neurorehabilitation.]]></content:encoded>
