Subgroup analyses and both linear and nonlinear meta-regression methods were used to explore moderating factors. Sixteen studies with \"some concerns,\" the risk of bias and low evidence level, were included. Combining blood flow restriction with low-intensity resistance training produced an effect size of 0.25 for strength, while combining blood flow restriction with aerobic training had an effect size of 0.42. For aerobic capacity, the effect size of combining blood flow restriction with aerobic training was 0.58. Subgroup and regression analyses showed no significant differences. While blood flow restriction with low-intensity resistance training enhances strength, it does not result in additional gains. Combining blood flow restriction with aerobic training enhances both the strength and the aerobic capacity. Overall, blood flow restriction appears to offer the most benefits for male athletes in improving the strength and aerobic capacity.","PeriodicalId":14439,"journal":{"name":"International journal of sports medicine","volume":" ","pages":"467-481"},"PeriodicalIF":2.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143399134","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 evaluated the validity of ratings of perceived exertion as a measure of fatigue during power bench press exercises. Fourteen sub-elite male athletes completed three bench press tasks with varying volumes (low, medium, and high) at 65% of their one-repetition maximum. The rating of perceived exertion, a spectral fatigue index, and velocity loss were measured across all conditions. Significant effects were observed for the overall ratings of perceived exertion, average velocity loss, and average spectral fatigue index (all p<0.001). As tasks progressed, the rating of perceived exertion and the spectral fatigue index increased significantly (p<0.001), while the velocity loss was not significant under the low-volume condition. Significant correlations were found between the rating of perceived exertion and the spectral fatigue index (r=0.547, p<0.001), the velocity loss and the spectral fatigue index (r=0.603, p<0.001), and the rating of perceived exertion and the velocity loss (r=0.667, p<0.001). The findings suggest that both the rating of perceived exertion and the velocity loss are valid measures of fatigue in power bench press exercises. However, the rating of perceived exertion is a more practical option due to its simplicity and accessibility. Furthermore, the rating of perceived exertion can act as a substitute for velocity when measurement tools are unavailable. It should be noted that velocity alone may not fully capture fatigue in low-repetition power training.","PeriodicalId":14439,"journal":{"name":"International journal of sports medicine","volume":" ","pages":"437-445"},"PeriodicalIF":2.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12148496/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143492097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A hip adductor strength test is a widely used tool to assess hip adduction strength, which is a key risk factor for these injuries. Despite its common usage, there is a lack of standardized guidelines regarding the measurement protocol, leading to inconsistent and unreliable applications. This review aims to synthesize existing research on hip adductor strength testing, highlighting the importance of developing clear guidelines for its implementation. This review covers various aspects of the test, including pre-test warm-up protocols, body positioning, device placement, test execution, verbal commands, data collection and selection, and timing of tests. Key findings suggest that standardized warm-up routines, consistent body and device positioning, clear verbal commands, and specific criteria for invalidating test trials are critical for enhancing the reliability and accuracy of the test. Furthermore, consistent timing and the documentation of test conditions are essential for effective athlete monitoring and injury prevention. By establishing and adhering to these guidelines, sports scientists and medical personnel can make well-informed decisions about athletes' hip adduction strength, ultimately improving injury prevention and performance outcomes in sports.","PeriodicalId":14439,"journal":{"name":"International journal of sports medicine","volume":" ","pages":"459-466"},"PeriodicalIF":2.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143639453","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 aimed to investigate the characteristics and post-injury management practices of severe spinal injuries among elite male wrestlers, with a comparative analysis between Greco-Roman and freestyle wrestling styles. A total of 110 elite male wrestlers (55 Greco-Roman and 55 freestyle athletes) were participated in the study, interviews were conducted severe spinal injuries and their post-injury management practices. Approximately 30.9% of participants reported experiencing severe spinal injuries, and among them, 58.8% were reinjury. These injuries predominantly occurred during technical training sessions due to overuse mechanisms during offensive maneuvers. Among the injured athletes, only 38.2% received specialized rehabilitation, and 35.3% obtained medical clearance before returning to play. The Greco-Roman style was found to have a significantly higher risk of reinjury than the freestyle (odds ratio=5.24 and 95% confidence interval=1.09-21.25). There were significant differences in the specific situations causing spinal injuries between wrestling styles (p=0.018). In conclusion, this study demonstrates that elite male wrestlers are at high risk of severe spinal injury and reinjury; yet, they often lack adequate post-injury management. Moreover, the differences in reinjury rates and specific situations causing injuries based on wrestling styles emphasize the need for tailored prevention and management strategies for each style.","PeriodicalId":14439,"journal":{"name":"International journal of sports medicine","volume":" ","pages":"525-532"},"PeriodicalIF":2.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143624759","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}

Participants completed anxiety, pain-interference, and kinesiophobia ratings and postural control tests (single/dual-task tandem gait and a modified balance error scoring system). Using a multivariable linear regression model, we evaluated the relationship among anxiety, pain-interference, and kinesiophobia (predictors) with postural control measures (tandem gait and a modified balance error scoring system, outcomes), adjusting for sex and anxiety history. We enrolled 128 participants (53% female, age=15.4±1.7 y, and 9.3±4.0 d post-concussion). Higher anxiety was weakly correlated with slower dual-task tandem gait times (r=0.31; p=0.001) and more modified balance error scoring system errors (r=0.22; p=0.01). Multivariable modeling indicated that a higher post-concussion anxiety rating was associated with a slower dual-task tandem gait time (β=0.21, 95% confidence interval=0.01-0.41; p=0.04). The female sex was associated with slower single-task tandem gait (β=-3.01, 95% confidence interval=-6.01, -0.01; p=0.049). Adolescents with a higher anxiety post-concussion performed worse on dual-task tandem gait assessments, while pain-interference and kinesiophobia were not associated with postural control. Anxiety and impaired postural control are independently associated with poor concussion outcomes; thus, this association may inform individualized concussion care strategies.","PeriodicalId":14439,"journal":{"name":"International journal of sports medicine","volume":" ","pages":"446-455"},"PeriodicalIF":2.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143624757","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}

Unfortunately, the rates of community acquired methicillin resistant Staphylococcus aureus have followed a similar upward trend. Treatment options for community acquired methicillin resistant Staphylococcus aureus vary, ranging from topical or systemic antibiotics to more invasive interventions like incision, drainage, and intralesional injections. Preventive measures are also essential and include avoiding shared equipment, meticulous mat and gear cleaning, and eliminating bacterial colonization. While existing research supports the effectiveness of decolonization strategies in hospital settings, there is a pressing need to adapt and implement these approaches within the wrestling community.
