Studies often proposed a long mindfulness intervention with a low-intensity physical activity. This study aims to investigate the effects on physical performance of a brief mindfulness intervention with a running programme. Sixty-five trained runners were randomised in brief mindfulness or control groups. Intermittent maximum speed, heart rate variability and ratings of perceived exertion were performed at baseline, at 4 weeks and 8 weeks. Fat mass and physical fitness were assessed at baseline and 8 weeks after. A time*group interaction was detected for cardiorespiratory fitness tests (i.e. intermittent maximum speed and 3-min shuttle run tests). Cardiorespiratory fitness stagnated for the mindfulness group whereas it decreased significantly over time in the control group (p=0.01). No time*group interactions were detected for the other outcomes (p<0.05). Brief mindfulness intervention might potentially mitigate the fatigue-related performance decrements during the preparatory phase. The cardiorespiratory fitness decrease for the control group could be explained by the high training load during this time of the season. The stagnation in the mindfulness group might be illustrated by the development of some psychological skills.","PeriodicalId":14439,"journal":{"name":"International journal of sports medicine","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143476625","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}

However, its reliability remains unknown. In this study, we assessed the repeatability of durability (determined as the decline in power output after accumulated work). We recorded the highest power output values (maximum mean power values) attained by 18 professional cyclists (27±4 y) during training and competition for different effort durations (10 s and 1, 5, 10, and 20 min) after different levels of accumulated work (0-40 kJ/kg) during a cycling season. Repeatability was examined through the standard error of measurement and the intra-class correlation coefficient calculated from the two highest maximum mean power values obtained by each cyclist for each duration and level of accumulated work. A progressive decline of maximum mean power values compared to the non-fatigued state was observed after higher levels of accumulated work, particularly after 20 kJ/kg (p<0.001). All maximum mean power values showed high repeatability under fatigue states (all standard error of measurement<5% and intra-class correlation coefficient>0.90), with the lowest repeatability observed for the shortest efforts (10-s maximum mean power). These findings were confirmed separately for training sessions and competitions, albeit with lower repeatability (standard error of measurement<8% and intra-class correlation coefficient>0.80). The measure of durability appears therefore reliable, which might support its validity for monitoring field-based performance in professional cyclists.","PeriodicalId":14439,"journal":{"name":"International journal of sports medicine","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144078032","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 systematic scoping review was performed to map the evidence on sex differences in fatigue during and following resistance training in trained participants. PubMed, CINAHL and SPORTDiscus were searched following PRISMA-ScR guidelines. The protocol was prospectively registered. Of the 4,020 identified articles, 34 were included. These studies assessed sex differences in fatigue using various measures during single and multiple resistance training sets, performance relative to the baseline at various time points (0-5 min, 1-6 h, 24 h, and 48-96 h after resistance training), 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 resistance training were found when (1) more complex free-weight exercises were performed with moderate loads, (2) rest periods were shorter, and (3) 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":"2025-05-15","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}

Fifteen healthy adults performed squat and stoop lifting tasks under three knee range of motion (ROM) conditions (squat: free/0-60°/0-90°; stoop: free/0°/0-30°) using optoelectronic motion capture and electromyographic (EMG) systems. ANOVA one-way was applied to analyze lumbar spine angles in flexion/extension, side bending and rotation, and to assess muscle activation patterns for five posterior chain muscles. No significant effects of knee ROM restrictions were observed for lumbar flexion/extension or side bending (p > 0.15), but pelvic rotation differed significantly (p = 0.0103). EMG analysis showed increased activation of the Gastrocnemius Lateralis and Biceps Femoris (p < 0.001), while Gluteus Maximus and Latissimus Dorsi activation remained unchanged. Knee ROM restrictions influenced EMG muscle activation in distal posterior chain muscles and altered pelvic rotation, suggesting localized compensatory mechanisms.

Twenty-six individuals with previous ACLR and twenty controls participated.

In a randomized crossover design, 12 participants performed quadrupedal and bipedal walking on a treadmill at identical speeds. Physiological responses, including energy expenditure, carbohydrate oxidation rates, respiratory rate, and heart rate, were measured during both forms of locomotion. Quadrupedal walking significantly increased total energy expenditure by 4.15 Kcal/min [95% CI, 3.11 - 5.19 Kcal/min], due to a rise in carbohydrate oxidation of 1.70 g/min [95% CI, 1.02 - 2.24 g/min]. It also increased respiratory and heart rates, indicating higher metabolic demands. The exercise mainly activated upper limb muscles and the gluteus maximus in the lower limbs. Ten minutes of quadrupedal walking at the same speed as bipedal walking resulted in a 254.48% increase in energy consumption. This simple form of locomotion offers a strategy for enhancing physical activity, and supports the idea that energy optimization influenced the evolution of efficient bipedal locomotion.","PeriodicalId":14439,"journal":{"name":"International journal of sports medicine","volume":" ","pages":"344-355"},"PeriodicalIF":2.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142620697","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}
