The condition is characterized by progressive and generalized loss of muscle mass and strength, affecting physical performance. It is part of aging but can be exacerbated by pathophysiological conditions like cancer, and several factors such as a sedentary lifestyle, poor nutrition, chronic diseases, falls and immobilization. Numerous cellular mechanisms have been implicated in its pathogenesis, including hormonal changes, mitochondrial dysfunction, altered apoptotic and autophagic signalling, muscle fiber composition, as well as inflammatory pathways. To prevent sarcopenia, exercise is one of the most effective strategies, as it has a strong influence on both anabolic and catabolic muscle pathways and helps improve skeletal muscle function. A well-rounded, multicomponent exercise program that targets muscle strength, aerobic capacity, and balance is recommended for optimal results. While nutrition is essential for muscle maintenance, relying solely on dietary interventions is unlikely to fully address sarcopenia. Therefore, a combination of adequate nutrition and regular exercise, is recommended to promote muscle health and function. The purpose of this paper is to review sarcopenia from an aging viewpoint and discuss the role of exercise and nutrition as prevention and management options.","PeriodicalId":14439,"journal":{"name":"International journal of sports medicine","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143811451","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}

Incremental load tests were conducted to assess the symptomatic limit on separate days under normoxic and hypoxic conditions (oxygen concentration 15.4±0.8%) using an ergometer. The initial test environment was randomized. The peak oxygen uptake and blood lactate were monitored every minute, and Δ peak oxygen uptake (peak oxygen uptake under hypoxia - peak oxygen uptake under normoxia) was calculated. Sixteen genotypes linked to exercise tolerance (such as angiotensin-converting enzyme [ACE]) were examined. Peak oxygen uptake significantly decreased under hypoxia (p<0.01). Δ peak oxygen uptake varied among individuals (minimum: 0.7 and maximum: - 18.9). Among analyzed genetic polymorphisms, ACE-II genotypes showed significantly greater Δ peak oxygen uptake than ACE-ID/ACE-DD genotypes (p=0.02). ACE-II genotypes exhibited lower blood lactate elevation at peak exercise in normoxic (p=0.01) and hypoxic (p=0.03) conditions. Participants with the ACE-II genotype had lower lactate concentrations and greater reductions in peak oxygen uptake under hypoxic conditions. Optimizing hypoxic training requires individualized programs incorporating genetic analysis.","PeriodicalId":14439,"journal":{"name":"International journal of sports medicine","volume":" ","pages":"246-254"},"PeriodicalIF":2.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142949018","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}

Exosomes are a novel class of intercellular signaling regulators containing cell-specific proteins, lipids, and nucleic acids that transmit messages between cells and tissues. MicroRNAs are regulatory non-coding ribonucleic acids that are usually present in exosomes as signaling molecules. Studies have shown that exosomes and exosomal microRNAs can improve the prognosis of ischemic stroke by inhibiting the inflammatory response, reducing apoptosis, improving the imbalance of oxidative and antioxidant systems, and regulating cellular autophagy, among other processes. Previous studies have shown that exercise training can exert neuroprotective effects on ischemic stroke by promoting the release of exosomes and regulating the expression of exosomal microRNAs, which in turn regulate multiple signaling pathways. Exosomes and exosomal microRNAs may be key targets for exercise to promote cerebrovascular health. Therefore, the study of exercise-mediated exosomes and their microRNAs may provide new perspectives for exploring the mechanism of exercise intervention in the prevention and treatment of ischemic stroke.","PeriodicalId":14439,"journal":{"name":"International journal of sports medicine","volume":" ","pages":"237-245"},"PeriodicalIF":2.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143005308","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}

These data processing choices, such as averaging duration, affect calculated values such as ˙VO2max. However, assessing the implications of data processing without knowing popular methods worth comparing is difficult. In addition, such details aid study reproduction. We conducted a semi-automated scoping review of articles with exercise testing that collected data breath-by-breath from three databases. Of the 8,344 articles, 376 (mean: 4.5% and 95% confidence interval: 4.1-5.0%) and 581 (mean: 7.0% and 95% confidence interval: 6.4-7.5%) described outlier removal and interpolation, respectively.

The commonly documented outlier cutoffs were±3 or 4 SD (39.1 and 51.6%, respectively). The dominating interpolation duration and procedure were 1 s (93.9%) and linear interpolation (92.5%). Averaging methods commonly described were 30 (30.9%), 60 (12.4%), 15 (11.6%), 10 (11.0%), and 20 (8.1%) second bin averages. This shows that studies collecting breath-by-breath data often lack detailed descriptions of data processing methods, particularly for outlier removal and interpolation.

We conducted a cross-sectional study evaluating adolescents with a recent concussion. We hypothesized that those reporting higher levels of anxiety, pain-interference, and kinesiophobia would perform worse on postural control tests. 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.
