Monitoring performance in football often combines physical testing and GPS-derived external-load measures, although their relationships remain unclear. This study examined the relationships between physical-test outcomes and GPS-derived external-load variables during the pre-season in professional female football players and whether these measures appear to capture distinct dimensions of performance. This observational study monitored 24 outfield players from a Brazilian Women's First Division team during a 6-week pre-season. Players performed the countermovement jump, 10 m and 30 m sprints, change-of-direction test, and 30-15 intermittent fitness test while external load was recorded across field sessions. Associations were examined using Pearson's or Spearman's correlations, and principal component analysis (PCA) was applied. Significant correlations were more frequent within than between domains. Total distance correlated with accelerations (ρ = 0.740, p < 0.001), decelerations (ρ = 0.684, p < 0.001), Z3 distance (ρ = 0.595, p = 0.003), and Z4 distance (ρ = 0.584, p = 0.003), while sprint count correlated with sprint distance (r = 0.950, p < 0.001). Estimated VO2max correlated positively with CMJ (r = 0.533, p = 0.007) and negatively with 10 m (r = -0.445, p = 0.029) and 30 m sprint times (r = -0.476, p = 0.019). PCA identified two components explaining 61.4% of the total variance: external load (40.6%) and physical performance (20.8%). These findings indicate that both approaches capture distinct and complementary aspects of performance.
监测足球运动员的表现通常结合了身体测试和gps衍生的外部负荷测量,尽管它们之间的关系尚不清楚。本研究考察了职业女足运动员季前体能测试结果与gps衍生的外部负荷变量之间的关系,以及这些测量是否能捕捉到表现的不同维度。这项观察性研究在6周的季前赛期间监测了来自巴西女子甲级联赛球队的24名外场球员。运动员进行了反向跳跃、10米和30米短跑、方向改变测试和30-15间歇性体能测试,同时记录了各场次的外部负荷。使用Pearson’s或Spearman’s相关性检验关联,并应用主成分分析(PCA)。显著相关性在域内比域间更为频繁。总距离与加速度(ρ = 0.740, p < 0.001)、减速(ρ = 0.684, p < 0.001)、Z3距离(ρ = 0.595, p = 0.003)和Z4距离(ρ = 0.584, p = 0.003)相关,而冲刺次数与冲刺距离相关(r = 0.950, p < 0.001)。估算VO2max与CMJ呈正相关(r = 0.533, p = 0.007),与10 m (r = -0.445, p = 0.029)和30 m短跑次数呈负相关(r = -0.476, p = 0.019)。PCA确定了两个组成部分,解释了总方差的61.4%:外部负荷(40.6%)和物理性能(20.8%)。这些发现表明,这两种方法都捕捉到了绩效的不同和互补方面。

Combat-sport performance depends on the interaction between technical skills and physical capacities, yet direct comparisons between grappling disciplines remain limited. The aim of this study was to compare the anthropometric profile and physical performance of elite judo and jiu-jitsu athletes. This cross-sectional study included 25 elite male athletes (judo-n = 12; jiu-jitsu-n = 13) assessed during a preparatory training phase. Anthropometric measures included age, training experience, height, and body mass, while physical performance was evaluated using dominant and non-dominant handgrip strength, squat jump (SJ), countermovement jump (CMJ), medicine ball throw with and without countermovement, and dynamic and isometric judogi-grip pull-up tests. Between-group comparisons were performed using independent sample tests, with effect sizes (ES) calculated. Judo athletes had greater training experience (13.25 ± 2.73 vs. 7.85 ± 4.36 years; p = 0.001; ES = 1.472) and higher SJ performance (38.71 ± 6.69 vs. 33.82 ± 4.74 cm; p = 0.045; ES = 0.850) compared to jiu-jitsu athletes. No significant between-group differences were observed for the remaining variables (p > 0.05). These findings indicate that no statistically significant differences were detected in most anthropometric and physical performance variables between elite judo and jiu-jitsu athletes, and the initially higher squat jump performance observed in judo athletes was no longer statistically significant after adjustment for training experience.
格斗运动的表现取决于技术技能和身体能力之间的相互作用,但在格斗学科之间的直接比较仍然有限。本研究的目的是比较优秀柔道和柔术运动员的人体测量特征和身体表现。本横断面研究包括25名优秀男性运动员(柔道12人,柔术13人)在预备训练阶段进行评估。人体测量包括年龄、训练经验、身高和体重,而身体表现则通过优势和非优势握力、深蹲跳(SJ)、反动作跳(CMJ)、有和没有反动作的实心球投掷、动态和等距柔道握力引体向上测试来评估。采用独立样本检验进行组间比较,计算效应量(ES)。柔道运动员的训练经验(13.25±2.73∶7.85±4.36∶p = 0.001; ES = 1.472)高于柔道运动员(38.71±6.69∶33.82±4.74 cm; p = 0.045; ES = 0.850)。其余变量组间差异无统计学意义(p < 0.05)。这些结果表明,优秀柔道运动员和优秀柔道运动员在大多数人体测量和体能表现变量上没有统计学差异,柔道运动员最初更高的深蹲跳表现在训练经验调整后不再具有统计学意义。

Combined functional training (FT), high-intensity interval training (HIIT) and aquatic exercise may improve health-related fitness in aging populations; however, the influence of baseline adiposity on training responses remains unclear. This study evaluated the effects of a 12-week multicomponent training program on aerobic capacity, body composition, metabolic health, and physical performance in middle-aged and older women and explored whether baseline body fat percentage modulated these responses. Thirty-four women (50-72 years) were assigned to a control group (Ctrl, n = 10) or an exercise group, stratified into normal fat (NF%, n = 10) and high fat (HF%, n = 14). The intervention included three weekly 60 min sessions consisting of HIIT, FT, and aquatic-based interval and resistance exercises, while controls maintained their habitual lifestyle without structured exercise. Significant improvements were observed in VO2max, skeletal muscle mass, fasting insulin, triglycerides, total cholesterol, HDL cholesterol, and functional performance. Baseline adiposity influenced metabolic adaptations, with greater improvements in the HF% group. These findings suggest that multicomponent training may improve cardiometabolic health and physical performance; however, the results should be interpreted cautiously due to the quasi-experimental design and small sample size.

This study aimed to evaluate the within-system agreement and interchangeability of real-time and post-processed external load metrics in elite football. Data were collected from 50 official Serie A matches using Dynamix (K-Sport World S.R.L., Pesaro, Italy), the platform for acquiring and standardizing tracking inputs. SmartLive, a real-time monitoring module embedded within Dynamix, was compared with post-processed data from the league-approved optical tracking provider (Hawk-Eye Innovations Limited, Basingstoke, UK) in Serie A. The external load metrics analyzed included total distance covered; distances at speeds exceeding 15, 20, and 25 km·h-1; distances within the 15-20 km·h-1 and 20-25 km·h-1 ranges; distance covered during accelerations > 2 m·s-2 and decelerations < -2 m·s-2; and peak speed. Intraclass correlation coefficients (ICCs) demonstrated excellent agreement across all metrics, with values ranging from 0.929 to 0.999. Bland-Altman analysis revealed small mean differences between systems, indicating strong agreement. Overall, the findings confirm that both real-time and post-processed data are in close agreement across a wide range of performance metrics. Minor discrepancies were observed in intermediate speed zones and acceleration/deceleration events. This study provides the first validation of SmartLive's within-system agreement with post-processed data, supporting its use alongside post-processed data in elite football environments.

Overhead sports place high demands on the shoulder complex, making warm-up specificity relevant for acute readiness. This randomized controlled pilot trial compared the immediate effects of a shoulder-specific warm-up with a habitual routine in 24 youth competitive overhead athletes (14-20 years), allocated to an experimental group (EG = 12) and a habitual warm-up group (SWG = 12). The warm-up protocol was administered bilaterally to both shoulders, whereas outcome measurements were collected unilaterally, with each shoulder tested separately. Assessments were performed before and immediately after the warm-up protocol. Outcome measures included shoulder flexion range of motion (ROM), handgrip strength, Closed Kinetic Chain Upper Extremity Stability (CKCUES) performance, and post-warm-up Rating of Perceived Exertion (RPE; Borg CR-10). A significant group-by-time interaction was found for right shoulder flexion ROM (p = 0.003, η2p = 0.346), with a significant increase in the EG from baseline to post-test (p = 0.008). No significant effects were observed for left shoulder flexion ROM, handgrip strength, or CKCUES performance. Post-warm-up RPE was statistically significant in the EG compared to the SWG (p = 0.041). These preliminary findings may suggest the potential practical value of more targeted warm-up strategies in overhead sports, while larger longitudinal studies are needed to confirm their broader functional relevance.

High-intensity interval training (HIIT) and small-sided games (SSG) are popular conditioning tactics in team sports, but their relative efficiency among female basketball players is uncertain. The aim of this study was to examine and compare the effects of a six-week HIIT and SSG intervention on the physical performance of elite female basketball players. Forty-four participants (20.98 ± 4.58 years) were randomly assigned to one of three groups: HIIT (n = 14), SSG (n = 14), or control (n = 16). Pre- and post-intervention evaluations assessed sprint performance (0-10, 0-20, 0-30 m), agility (Pro-agility, Zig-zag, 9-6-3-6-9 tests), vertical jump height (CMJ, CMJA, SJ), repeated sprint ability (RSA), and aerobic capacity (VO2max, VIFT, MAS). HIIT and SSG significantly improved all performance measures compared to the control group (p < 0.001, ηp2 = 0.365-0.809); however, there were no significant differences between the two experimental groups. HIIT had a slightly greater effect on linear sprinting, but SSG was more effective for agility and aerobic performance. Body composition remained unchanged. These data suggest that HIIT and SSG are both effective training methods for improving speed, agility, explosive power, RSA, and aerobic capacity in female basketball players. Incorporating both strategies into an organized training program can improve sport-specific performance and overall conditioning.

Endurance training camps are well established in elite sports, but one-week camps for recreational endurance athletes have recently gained popularity despite limited scientific evidence. This study investigated the effects of a one-week endurance training camp on body composition, endurance performance, and markers of metabolic stress and mitochondrial adaptation in recreational athletes. Female and male endurance athletes (≥18 years) participated in a professionally guided one-week endurance training camp. Assessments included body composition, running diagnostics, sleep-quality/recovery-stress questionnaires, nutrition/energy balance diaries, blood profiling, and mitochondrial biogenesis markers. Measurements were conducted before (pre), during (camp), and after the camp (post). A total of 35 participants (18 male/17 female) were included. Body mass and body fat decreased from pre- to post-camp. Lactate concentrations at threshold levels changed, while velocities at fixed lactate concentrations and maximal oxygen uptake did not significantly improve. Post-camp, lactate dehydrogenase, klotho, and vitamin D increased, whereas interferon-γ, kynurenine, cortisol, creatinine, and ferritin decreased. Plasma mitochondrial and nuclear DNA abundance, as well as PGC1-α expression, increased, while vascular endothelial growth factor decreased. A one-week endurance training camp in a holiday-like setting induces measurable physiological, metabolic, and mitochondrial adaptations in recreational athletes and is associated with reduced systemic and psychological stress. However, the concurrent increase in muscle- and cell-stress markers indicates a substantial physiological load.

Female and male endurance athletes (≥18 years) participated in a professionally guided one-week endurance training camp. Assessments included body composition, running diagnostics, sleep-quality/recovery-stress questionnaires, nutrition/energy balance diaries, blood profiling, and mitochondrial biogenesis markers. Measurements were conducted before (pre), during (camp), and after the camp (post). A total of 35 participants (18 male/17 female) were included. Body mass and body fat decreased from pre- to post-camp. Lactate concentrations at threshold levels changed, while velocities at fixed lactate concentrations and maximal oxygen uptake did not significantly improve. Post-camp, lactate dehydrogenase, klotho, and vitamin D increased, whereas interferon-γ, kynurenine, cortisol, creatinine, and ferritin decreased. Plasma mitochondrial and nuclear DNA abundance, as well as PGC1-α expression, increased, while vascular endothelial growth factor decreased. A one-week endurance training camp in a holiday-like setting induces measurable physiological, metabolic, and mitochondrial adaptations in recreational athletes and is associated with reduced systemic and psychological stress. However, the concurrent increase in muscle- and cell-stress markers indicates a substantial physiological load.</p>","PeriodicalId":53303,"journal":{"name":"Sports","volume":"14 5","pages":""},"PeriodicalIF":2.9,"publicationDate":"2026-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13211031/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148036787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pre-elite female field hockey players have a high incidence of lower extremity injury, highlighting the need for practical and reliable screening approaches. A dual assessment combining Functional Performance Tests (FPTs) with movement quality scoring (QASLS) may provide a more comprehensive evaluation; however, its reliability in this population is unclear. Fifteen pre-elite female field hockey players (16.7 ± 0.7 years) completed an FPT battery (anterior reach (AR), single leg drop vertical jump-land (DVJL), single hop for distance (SHFD), side hop (SH)) on two occasions, 28 days apart. Movement quality was assessed by three raters using QASLS. Reliability was evaluated using ICC with 95% confidence intervals (CI), alongside standard error of measurement (SEM), smallest detectable difference (SDD), and percentage exact agreement (PEA). Test-retest reliability varied across tasks (ICC2,1 0.33-0.90), with wide confidence intervals indicating uncertainty in several estimates. AR demonstrated the most consistent reliability, supporting its use for monitoring over time. In contrast, the DVJL and SH showed the greatest variability, likely reflecting higher task complexity, while the SHFD required relatively large performance changes to exceed measurement error. Intra-rater reliability for QASLS was consistent across the FPT battery (ICC2,k 0.79-0.90), whereas inter-rater reliability was more variable (0.38-0.82), indicating rater-dependent differences. PEA demonstrated generally high agreement (60-100%), although lower agreement was observed for pelvic alignment components. These findings support the use of a dual assessment approach as a practicable profiling approach in pre-elite female field hockey, enabling practitioners to identify movement deficits not captured by performance metrics alone. However, variability in complex tasks and between raters highlights the need to consider measurement error and implement standardised rater training when profiling or monitoring performance.

Perceptual-cognitive abilities are essential components of performance in volleyball, where players must quickly interpret visual information and respond effectively to rapidly changing game situations. The present study aimed to examine perceptual-cognitive abilities and reaction performance in competitive female volleyball players and to explore how these abilities may contribute to athlete development and training design. Thirty-nine young female volleyball athletes participated in the study and underwent an evaluation of perceptual-cognitive abilities considered critical for volleyball performance. These abilities were assessed through specially designed computer-based tasks delivered via dedicated experimental software, enabling the measurement of reaction time and response accuracy during perceptual-motor processing. Group comparisons did not reveal significant differences between playing positions or competitive levels in the measured perceptual-cognitive abilities. Multivariate and clustering analyses suggested the presence of potential performance patterns characterized by different combinations of reaction speed, response accuracy, and perceptual-cognitive processing. However, these patterns should be interpreted with caution, as the clustering solution showed limited separation (silhouette score = 0.02), indicating an exploratory and non-definitive structure. Overall, the findings highlight the multidimensional nature of perceptual-cognitive performance in volleyball and suggest that athletes may rely on different perceptual-motor strategies when responding to game-related stimuli. From an applied perspective, integrating perceptual-cognitive challenges into training environments may support athlete development and improve decision-making efficiency in dynamic game situations.
