Nineteen physical education students performed three adductor strength test protocols in a supine position with hips and knees extended: (a) unilateral, (b) bilateral, and (c) bilateral following a unilateral adduction fatigue protocol. Bilateral and unilateral strength measures indicated good-excellent reliability across tests (intraclass correlation coefficient>0.88 and coefficient of variation<8%), while unilateral symmetry showed poor reliability (intraclass correlation coefficient=0.47 and coefficient of variation=13%). Bilateral testing produced statistically significantly higher strength values (p<0.05) than unilateral testing; however, no significant differences were observed between unilateral and bilateral tests under fatigued conditions, regardless of leg preference (preferred or non-preferred). Despite an average strength decrease of 35% after the unilateral fatiguing protocol, bilateral test symmetry results did not change (101% vs. 106%). A very strong correlation was observed between bilateral and unilateral adductor strength results (r=0.81-0.86); yet, no correlation was significant for symmetry results (r<0.35, p>0.05). Due to the limited sensitivity of the bilateral adduction test for detecting changes in symmetry values, we recommend the unilateral testing protocol for practical use when assessing inter-leg adductor muscle strength asymmetries.","PeriodicalId":14439,"journal":{"name":"International journal of sports medicine","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143624758","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":""},"PeriodicalIF":2.0,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","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":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to investigate cardiovascular adaptation in university students engaged in intensive exercise using cardiac magnetic resonance imaging (MRI). For this prospective, single-center study, 50 university students who finished a four-year's intensively endurance training and 23 age- and gender- matched controls received cardiac MRI. Exercised participants were further divided into symptomatic and asymptomatic groups. Left ventricular (LV) volumes and indexed to body surface were calculated.

Fifty exercised participants (mean age, 21years ± 1, 43 males, including 21 symptomatic and 29 asymptomatic cases) and 23 normal controls (mean age, 21years ± 2, 20 males) were evaluated. Exercised participants exhibited higher end-diastolic LV volume (76.0ml ± 10.6 vs 63.5ml ± 7.5, P <0.001), reduced LV ejection fraction (59.9% ± 5.3 vs 63.0% ± 3.2, P = 0.002) and reduced global longitudinal strain (-18.25 ± 3.32 vs -19.85 ± 1.29, P = 0.004) than the normal control did. Symptomatic excised participants showed reduced peak strains compared to both asymptomatic participants and normal controls. Only circumferential DSR was reduced when compared between asymptomatic cases and the controls. In conclusions, highly intensive exercise could result in elevated LV volume and reduced myocardial strains for young university students. Further, 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":""},"PeriodicalIF":2.0,"publicationDate":"2025-03-20","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}

These studies assessed sex differences in fatigue using various measures during single and multiple RT sets, performance relative to baseline at various time points (0-5 min, 1-6 h, 24 h, and 48-96 h after RT), and metabolic responses. Substantial heterogeneity in study design and results were observed. Together, most studies found minor-to-no sex differences in neuromuscular fatigue, but some evidence of greater fatigability in males during or immediately following RT were found when i) more complex free-weight exercises were performed with moderate loads, ii) rest periods were shorter, and iii) males were substantially stronger than females in relative terms, among others.

Endurance was assessed at 240°/s through 25 repetitions, analyzing peak torque changes. On the first day, participants performed general warm-ups followed by balance and strength tests. Subsequent sessions repeated these tests with additional measurements. Results showed that proprioceptive neuromuscular facilitation warm-ups significantly improved the static and dynamic balance compared to other methods. Peak torque measurements at all speeds also highlighted the superior effectiveness of proprioceptive neuromuscular facilitation warm-ups. Additionally, this warm-up approach provided greater acute enhancement in knee joint isokinetic endurance. In conclusion, proprioceptive neuromuscular facilitation warm-ups increased the isokinetic strength, endurance, and balance in football players. Incorporating proprioceptive neuromuscular facilitation warm-ups into football training especially for lower body preparation is recommended.

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.
