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}

The first lactate threshold (LT1) was assessed using the log-log transformation of blood lactate and running speed (LT1log-log), an increase of 1 mM above baseline (LT1Bsln1.0), and a fixed blood lactate concentration of 2 mM (LT1OBLA2). The second lactate threshold (LT2) was determined using the maximal distance approach (LT2Dmax) and a fixed lactate concentration of 4 mM (LT2OBLA4). The highest (FATmax) and lowest (FATmin) fat oxidation rates were determined using a 3rd-degree polynomial regression (P3), visual inspection, and mathematical modeling (SIN). FATmax and FATmin showed the strongest correlation with LT1log-log (r: 0.65, p<0.01) and LT2OBLA4 (r: 0.81, p<0.01), regardless of fitness. FATmaxP3 and LTOBLA2 showed the best agreement in untrained individuals. Conversely, FATmaxP3 and LT1log-log showed the best agreement in obese men and trained subjects. LT2OBLA4 showed the best agreement with FATmin. When investigating the association between fat oxidation and lactate metabolism during exercise, LT1log-log and LT2OBLA4 should be computed, while mathematical modeling or visual analysis should be applied for FATmax, depending on fitness level.","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":"143669207","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. Global peak strains, systolic and diastolic peak strain rates (DSR) were derived from cine images using feature tracking technique. ANOVA analyses were performed. 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. Future investigations should explore the impact of training variables and habitual training on fatigue in males and females of comparable relative strength and technical proficiency.","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":"143669833","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}

After the current applied to the quadriceps muscles, strength and anaerobic power tests were performed. Perceived exertion assessment was also collected after the performance tests. The 75Hz current showed better performance in dominant (p<0.001, d=0.75) and non-dominant (p<0.001, d=0.69) quadriceps muscle group strength (kg). The 75Hz current condition peak power had significantly higher values than 15Hz (p<0.05, d=0.38) and 104Hz conditions (p<0.05, d=0.60).

Data collection spanned four sessions, each separated by full rest. The isokinetic strength of the hip, knee, and ankle flexion and extension was measured using a dynamometer at 60°/s, 180°/s, and 240°/s. 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. Combining them with active warm-ups may further boost acute performance.","PeriodicalId":14439,"journal":{"name":"International journal of sports medicine","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143663421","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}
