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":""},"PeriodicalIF":2.0,"publicationDate":"2025-07-08","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}

Twenty sedentary men completed three exercise sessions using a crossover design: (1) hypoxic exercise at 50% of peak power output, (2) normoxic exercise at 50% of peak power output (normoxic exercise matched for mechanical intensity), and (3) normoxic exercise with heart rates matched for hypoxic exercise. Expired gases and peripheral and muscle oxygen saturation were measured during the exercise. Blood pressure and hemodynamic variables were assessed before and after each exercise session. Hypoxic exercise and normoxic exercise matched for physiological intensity elicited higher heart rate, oxygen consumption, and ventilation compared to normoxic exercise matched for mechanical intensity (p<0.05). Hypoxic exercise showed the lowest ventilation efficiency (p<0.01) and the most severe systemic and muscle hypoxemia (p<0.01) during exercise. Only hypoxic exercise induced significant post-exercise hypotension (-6.9 mmHg; p<0.01) with a significant increase in common femoral artery diameter during recovery (p<0.05). Our findings suggested that hypoxic exercise significantly enhances post-exercise vasodilation compared to normoxic exercise, resulting in greater post-exercise hypotension. This highlighted hypoxic exercise as a promising strategy for managing hypertension with reduced mechanical stress, particularly beneficial for individuals with low exercise tolerance.","PeriodicalId":14439,"journal":{"name":"International journal of sports medicine","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144583918","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}

Owing to the lack of studies on adolescent female athletes, this study aimed to investigate the relationship between whole-body and regional phase angles and exercise performance in adolescent female basketball players. Forty-five female basketball players (aged 16.6±0.6 y) participated in this study. Lean soft tissue and phase angles for the whole-body, upper limb, and lower limb were assessed using the bioelectrical impedance analysis method. Participants performed maximal isometric knee extension and flexion strength, 20-m sprint, a vertical jump, an agility T-test, and a 20-m shuttle run test. The phase angle for the whole-body and the phase angle for the upper limb, but not the phase angle for the lower limb, were significantly correlated with the 20-m sprint and endurance capacity (all p<0.01). Even after adjusting for age and lean soft tissue in multiple regression analysis, the phase angle for the whole-body and the phase angle for the upper limb remained a significant predictor of these parameters (all p<0.05). The phase angle for the upper limb, combined with age and lean soft tissue, explained endurance capacity similarly to the phase angle for the whole-body (adjusted R 2: 0.24 vs. 0.23) but was better for the 20-m sprint (adjusted R 2: 0.26 vs. 0.11). Both whole-body and regional phase angles are associated with sprint and aerobic performance in adolescent female basketball players. However, the regional phase angle can be an equivalent or superior predictor of these performance parameters compared with the whole-body phase angle.","PeriodicalId":14439,"journal":{"name":"International journal of sports medicine","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143990291","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 18 articles were included in the current systematic review. The resurfacing hip arthroplasty group exhibited faster functional recovery after surgery compared to total hip arthroplasty by improving the hip range of motions, peak vertical ground reaction force, and peak hip abduction moment. Evaluation of the biomechanical changes during stair negotiation and sit-to-stand transfers is further needed to evaluate comprehensive aspects of functional ability. The findings of this review provide a comprehensive overview and help to understand the biomechanical changes for patients with total hip arthroplasty vs. resurfacing hip arthroplasty during daily activities.

This study aimed to investigate cardiovascular adaptation in university students engaged in intensive exercises using cardiac magnetic resonance imaging. For this prospective, single-center study, 50 university students who finished a four-year intensively endurance training and 23 age- and gender- matched controls received cardiac magnetic resonance imaging. Exercised participants were further divided into symptomatic and asymptomatic groups. Left ventricular volumes and volumes indexed to the body surface were calculated. Global peak strains and systolic and diastolic peak strain rates were derived from cine images using a feature tracking technique. Analysis of variance analyses were performed. Fifty exercised participants (mean age: 21±1 y; 43 males, including 21 symptomatic and 29 asymptomatic cases) and 23 normal controls (mean age: 21±2 y, 20 males) were evaluated. Exercised participants exhibited a higher end-diastolic left ventricular volume (76.0±10.6 ml vs. 63.5±7.5 ml, p<0.001), a reduced left ventricular ejection fraction (59.9%±5.3 vs. 63.0%±3.2, p=0.002) and a reduced global longitudinal strain (-18.25±3.32 vs.-19.85±1.29, p=0.004) than the normal control participants. Symptomatic excised participants showed reduced peak strains compared to both asymptomatic participants and normal controls. Only a circumferential diastolic peak strain rate was reduced when compared between asymptomatic cases and controls. In conclusions, highly intensive exercises could result in elevated left ventricular volumes and reduced myocardial strains for young university students. Furthermore, reduced myocardial strains were found for those symptomatic cases which remain within non-pathological ranges.","PeriodicalId":14439,"journal":{"name":"International journal of sports medicine","volume":" ","pages":"604-613"},"PeriodicalIF":2.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143669834","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}
