Post-traumatic OA (PTOA) is more common in younger populations, especially after anterior cruciate ligament (ACL) or meniscal injury. Identifying those at increased risk of PTOA using molecular, imaging and biomechanical biomarkers is a research priority. This systematic review aims to identify functional tasks used to assess knee kinematics and kinetics at least a year from injury, describe any differences found between the injured and uninjured contralateral and control knees and identify associations with PTOA. Searches were performed on Medline, CINAHL and EMBASE, with reference lists reviewed. The initial search yielded 2504 studies, with six more detected from reference lists. Thirty-three studies involving 1251 participants (n=737 injured, all ACL, mean age 25.1, 49.9% male, 1-13 yr post-injury) were included. Studies included the following dynamic tasks: landing (n=25), jumping (n=3), cutting (n=5) or squatting (n=3). Overall, reductions in knee flexion and extension angles and moments, increased knee valgus and energy absorption were demonstrated in injured knees. However, this was inconsistent across studies, with data heterogeneity preventing direct comparison and meta-analysis. Changes in biomechanics are present from 1-year post-injury, persisting for several years; however, consensus regarding core outcome sets is required.","PeriodicalId":14439,"journal":{"name":"International journal of sports medicine","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144873172","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}

Following PRISMA guidelines, a comprehensive search was conducted across five databases (Ovid MEDLINE, EMBASE, CINAHL Complete, Web of Science, and Scopus) up to February 2025. Included studies involved healthy, active adults undergoing nutrient supplementation, dietary, and/or exercise interventions with a control or placebo comparator. Outcomes included faecal bacterial composition (α-diversity, relative abundance), short chain fatty acids (SCFA), in adjunct with exercise performance (i.e., time-trial, time to exhaustion, maximal strength). Eighteen studies met the inclusion criteria. Due to methodological heterogeneity, a descriptive synthesis was performed. Changes in faecal microbiota diversity and composition were highly variable and largely minimal. SCFA outcomes were infrequently assessed; only one study reported a significant increase in faecal acetate concentration following yoghurt supplementation containing Bifidobacterium animalis subsp. lactis BL-99. Only seven studies examined the relationship between changes in faecal bacterial profile and performance outcomes, with limited or inconclusive findings. No consistent performance benefits were observed in relation to microbiota changes. Risk of bias and methodological limitations were common, including variation in interventions, outcome measures, and microbiota analysis methods. Taken together, the current evidence base remains too limited and heterogeneous to draw firm conclusions about the efficacy of microbiota-targeted interventions for enhancing exercise performance in healthy, active adults. Future studies employing standardised methods, mechanistic outcome measures, and longitudinal designs may help clarify the potential of microbiota modulation as a performance-enhancing strategy.","PeriodicalId":14439,"journal":{"name":"International journal of sports medicine","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145086163","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}

This study investigated the relationships between 1RM, MAP, and time-to-exhaustion at MAP in 69 high-level and professional cyclists from the same national team, stratified by sex, category, and discipline. Cyclists underwent a two-day protocol to assess MAP via a graded exercise test, time-to-exhaustion at MAP, and 1RM via a velocity-based parallel back squat test. Spearman correlations, mixed models, generalized additive models, structural equation modeling, and cluster analysis examined strength-performance relationships, adjusted for covariates. 1RM strongly predicted MAP (r=0.73, β=0.86, p<0.001; 2.47 W increase per kg), and relative 1RM predicted MAP relative to body mass non-linearly (r=0.58, β=0.84, p<0.001). Time-to-exhaustion showed no significant strength association (p>0.05). Women exhibited lower MAP (-71.67 W, p<0.001), mountain bike cyclists showed longer time-to-exhaustion (+0.61 SD, p=0.049), and elite cyclists had higher MAP (+21.51 W, p=0.030), reflecting physiological and discipline-specific differences. Clusters highlighted strength-power distinctions.

No significant differences were found between high-intensity interval training and sprint interval training in terms of body composition changes. However, the time spent on sprint interval training was approximately 50% less than that of high-intensity interval training. Subgroup analysis suggested that sprint interval training with shorter work durations (less than 10 s) was more effective in obesity control. In conclusion, both high-intensity interval training and sprint interval training demonstrated similar effectiveness in improving body adiposity. Given its time efficiency and straightforward intensity monitoring, sprint interval training may serve as a viable alternative exercise program for promoting fat reduction in adults with overweight or obesity, provided that it is appropriately designed.","PeriodicalId":14439,"journal":{"name":"International journal of sports medicine","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143648517","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}

A total of 103 players were followed. Performance in 40-m sprint, countermovement jump (CMJ), leg press, and maximal oxygen consumption (V̇O2max) was tested biannually at seven time points. Maturity was estimated using bone age from hand-wrist X-rays. Latent growth modelling examined changes in maturity-performance associations over time. Maturity was significantly (p < 0.05) associated with sprint, CMJ, leg strength (force and power), and V̇O2 max at ages 14.1, 14.7, and 15.3 years. The associations were, however, less significant over time. Specifically, maturity was no longer statistically associated with sprint and CMJ performance at 15.7 years, force and V̇O2 max at 16.4 years, and power at 16.8 years. There were no significant associations at 17.4 years. Biological maturity influences physical capacities during early adolescence, but its impact diminishes as players age. The timing of this decline appears to vary between physical performance domains, with sprint and jump performance stabilizing earlier than muscular strength and aerobic capacity.","PeriodicalId":14439,"journal":{"name":"International journal of sports medicine","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144764881","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}
