Nine elite men's middle- and long-distance runners from the Brazilian Paralympic Endurance Team performed the GXT in a laboratory setting. MOT2 was determined by the breakpoint in the tissue saturation index (TSI) curve in both muscles by wearable near-infrared spectroscopy (NIRS). After 48 h, athletes performed a 3,000-m running test on an outdoor athletics track while monitoring the oxygenation in both muscles. MOT2 velocity values in BB (19.3±1.3 km.h-1) and VL (19.4±1.2 km.h-1) did not show a significant difference between them (p>0.05). We observed a significant correlation between BB and VL MOT2 with 3,000-m mean velocity (r=0.88 and 0.86, respectively, p<0.05). Our results reinforce that the maximal aerobic capacity determined in different muscles influenced the athletes' performance in the 3,000-m running.

Relative and absolute reliabilities were analyzed. Sensitivity was determined by comparing the smallest worthwhile change to the typical error of measurement and, in addition, changes in performance over the season were assessed in short-, medium-, and long-term periods. Results demonstrated high reliability across all tests, with intraclass correlation coefficient values ranging from 0.70 to 0.94 and coefficient of variation (CV) below 5%, meeting a priori reliability criteria. Vertical jumping exhibited the highest reliability (0.89-0.92) and was sensitive in detecting moderate-to-large changes. COD tests showed moderate-to-high reliability (0.70-0.89), with CODR180° sensitive to seasonal adaptations. Sprint tests also displayed good reliability (0.80-0.94); however, their sensitivity was limited. Notably, the unilateral jump tests and CODR180° exceeded CV thresholds, highlighting their potential to monitor significant improvements over time. Unilateral and COD-specific assessments emerged as particularly valuable for detecting performance changes, underscoring the need for sport-specific testing protocols in women's football.","PeriodicalId":14439,"journal":{"name":"International journal of sports medicine","volume":" ","pages":"908-917"},"PeriodicalIF":2.2,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144475236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Diagnosis is primarily based on a decline in maximal performance and a subjective feeling of 'staleness', after ruling out other medical conditions. This study aimed to identify physiological and self-reported predictors of OTS by comparing individuals diagnosed with OTS (n=110; 2008-2022) with a healthy control group (n=447; 2005-2023). Both groups consisted of athletes and recreational exercisers assessed at the Helsinki Sports and Exercise Medicine Clinic (HULA). Data were collected through questionnaires and spiroergometric testing and subsequently analysed using logistic regression, adjusting for age and sex. The results of this study suggest that fatigue, dizziness and shortness of breath, along with decreased maximum oxygen uptake (V̇O2max), peak blood lactate value (Lamax) and oxygen uptake at both ventilatory thresholds (V̇O2VT1 and V̇O2VT2), are significant predictors of OTS (p<0.05/54). Among reported health conditions, asthma, allergy, anaemia and mental health issues were statistically significant predictors of OTS at the 0.05 level, but not after Bonferroni correction. In conclusion, regular spiroergometric testing and symptom monitoring may support earlier diagnosis and improved management of OTS in athletes and recreational exercisers.","PeriodicalId":14439,"journal":{"name":"International journal of sports medicine","volume":" ","pages":"898-907"},"PeriodicalIF":2.2,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144591235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Six electronic databases were searched. Nine studies were included, reporting 18 effect sizes and comprising 152 participants. We assessed pre- and posttest differences using meta-analysis, conducted subgroup analyses to identify potential moderating factors, and employed nonlinear meta-regression to explore the relationship between rest intervals and the PAPE effect. The results showed that VBT-CA significantly improved athletic performance. Subgroup analyses showed no significant differences; nevertheless, bench press-type CA, CA with VL≤10%, load≥80% one-repetition maximum (1RM), single-set CA, and athlete population exhibited a trend toward larger PAPE effects. Between 5.77 and 12.8 minutes after VBT-CA, a significant PAPE effect was indicated by the meta-regression results, with the optimal time point being 8.96 minutes. Our study suggests that VBT-CA can effectively induce the PAPE effect.

Different methods and approaches alongside key definitions and concepts on health problem surveillance have been proposed during the last 30 years trying to address the main features clinicians and researchers should adopt to conduct appropriate injury and illness surveillance. The literature suggests that the collection of a core set of variables including location, tissue and pathology type, relation to sports activity, mode of onset, mechanism, and severity is needed to conduct appropriate injury and illness surveillance.

Fifteen healthy adults performed squat and stoop lifting tasks under three knee ROM conditions (squat: free/0-60°/0-90°; stoop: free/0°/0-30°) using optoelectronic motion capture and electromyographic (EMG) systems. One-way analysis of variance was applied to analyze lumbar spine angles in flexion/extension, side bending, and rotation and to assess muscle activation patterns for five posterior chain muscles. No significant effects of knee ROM restrictions were observed for lumbar flexion/extension or side bending (p>0.15), but pelvic rotation differed significantly (p=0.0103). EMG analysis showed increased activation of the Gastrocnemius Lateralis and Biceps Femoris (p<0.001), while Gluteus Maximus and Latissimus Dorsi activation remained unchanged. Knee ROM restrictions influenced EMG muscle activation in distal posterior chain muscles and altered pelvic rotation, suggesting localized compensatory mechanisms.

A total of 73 licensed male football players in the U15, U16, U17, and U19 age categories participated in the study.

Differences between age groups were statistically evaluated by one-way analysis of variance and linear regression analysis. The results showed that the hop test asymmetry index (AI), Q/Q, and H/H strength ratios decreased from U15 to U17 and increased again at U19 (p=0.037, p=0.025, p=0.002). Regression analysis revealed that age significantly influenced the hop test AI (5%), Q/Q strength ratio (5%), H/H strength ratio (12%), and dominant leg H/Q strength ratio (7%) (p<0.05). Overall, this study shows that muscle strength imbalances in young soccer players differ both bilaterally and unilaterally with age. While bilateral strength differences were relatively balanced in the U15-U17 age groups, a significant asymmetry was observed in the U19 group. In terms of unilateral strength, a certain development was observed in the dominant leg with age, while this development was limited in the nondominant leg.","PeriodicalId":14439,"journal":{"name":"International journal of sports medicine","volume":" ","pages":"918-926"},"PeriodicalIF":2.2,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144316921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Eleven male cyclists and triathletes performed a graded exercise test on a cycle ergometer. Muscle oxygen saturation was measured in the vastus lateralis, biceps femoris long head, erector spinae, and external oblique muscles at each intensity level, along with gross efficiency. The percentage of peak power output at which muscle oxygen saturation began to deoxygenate significantly decrease from the initial load was 60% in the vastus lateralis, 80% in the biceps femoris long head, and 70% in both the erector spinae and external oblique muscles (P < 0.05 or P < 0.01). In contrast, no significant differences in deoxygenation between muscles were observed at intensities between 60% and 90% of peak power output. At 80% of peak power output, a significant positive correlation was found between gross efficiency and oxygen saturation in the erector spinae (r = 0.745, P < 0.01). In conclusion, the oxygen saturation profile of core muscles are comparable to those of thigh muscles, and oxygen saturation in the erector spinae may contribute to gross efficiency during high-intensity cycling.","PeriodicalId":14439,"journal":{"name":"International journal of sports medicine","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145354607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When compared at key throwing timepoints, differences in pelvis and trunk kinematics were observed between sports. However, it is uncertain whether throwing-arm mechanics would differ throughout the throw between these athletic populations. Therefore, this study aimed to compare catchers' throwing mechanics between sports using continuous statistical analyses. A total of 20 catchers (baseball: n=10 and softball: n=10) participated in this study. Statistical parametric independent samples t-tests (α=0.05) were used to temporally compare proximal and throwing-arm kinematics from foot contact (0%) to maximum shoulder internal rotation (100%) between sports. Differences found included elbow flexion (p=0.008; 0-13 and 99-100%), shoulder rotation (p<0.001; 23-53%), elevation (p<0.001; 0-95%) and the plane of elevation (p<0.001; 0-100%), pelvis and trunk lateral flexion (pelvis: p=0.027; 0-30% and trunk: p<0.001; 23-100%) and rotation (pelvis: p=0.036; 4-21% and trunk: p=0.036; 84-100%), and trunk flexion (p<0.001; 34-100%). While most of the observed differences were brief, notable differences in the trunk flexion, trunk lateral flexion, shoulder elevation, and plane of elevation were apparent for much of the throwing motion. Time-series analyses identified distinct mechanics involved in baseball and softball throw downs, lending support for sport-specific biomechanical assessments on catchers.","PeriodicalId":14439,"journal":{"name":"International journal of sports medicine","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145345240","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Significant negative correlations were observed between 500 m race time and both mean force (r= -0.72; p=0.001) and peak force (r= -0.71; p=0.001) measured through the isometric dynamometric test. In the incremental test, a strong negative correlation was found between race time and the number of strokes (Nreps) (r= -0.85; p=0.001), as well as absolute peak force (r=-0.80; p=0.001). These relationships remained significant when force values were adjusted for body mass. The strongest predictive model (R2a=0.73) included the number of strokes from the incremental load test (C1 500-m race time = 170.30 - 3.29 Nreps).
