Athletes in contact sports, especially wrestlers, represent a unique subset of young, healthy individuals who are at heightened risk for transmitting methicillin resistant Staphylococcus aureus. The sport of wrestling has seen a significant increase in participation, particularly among adolescents, underscoring its growing popularity and the urgent need to address this issue. Unfortunately, the rates of community acquired methicillin resistant Staphylococcus aureus have followed a similar upward trend. Treatment options for community acquired methicillin resistant Staphylococcus aureus vary, ranging from topical or systemic antibiotics to more invasive interventions like incision, drainage, and intralesional injections. Preventive measures are also essential and include avoiding shared equipment, meticulous mat and gear cleaning, and eliminating bacterial colonization. While existing research supports the effectiveness of decolonization strategies in hospital settings, there is a pressing need to adapt and implement these approaches within the wrestling community. Current prevention methods, such as mat cleaning and skin checks before competitions, are insufficient on their own. By adopting more comprehensive decolonization protocols tailored to the wrestling environment, we can better protect athletes and reduce the incidence of community acquired methicillin resistant Staphylococcus aureus skin infections.","PeriodicalId":14439,"journal":{"name":"International journal of sports medicine","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143501266","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 (RPE) as a measure of fatigue during power bench press (BP) exercises. Fourteen sub-elite male athletes completed three BP tasks with varying volumes (low, medium, high) at 65% of their one-repetition maximum. RPE, spectral fatigue index (SFI), and velocity loss were measured across all conditions. Significant effects were observed for overall RPE, average velocity loss, and average SFI (all p < 0.001). As tasks progressed, RPE and SFI increased significantly (p < 0.001), while velocity loss was not significant in the low-volume condition. Significant correlations were found between RPE and SFI (r = 0.547, p < 0.001), velocity loss and SFI (r = 0.603, p < 0.001), and RPE and velocity loss (r = 0.667, p < 0.001). The findings suggest that both RPE and velocity loss are valid measures of fatigue in power BP exercises. However, RPE is a more practical option due to its simplicity and accessibility. Furthermore, RPE 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":"2025-02-24","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}

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":"2025-02-22","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}

Sport and exercise science research studies have investigated the effects of experimentally induced mental fatigue on cognitive performance, with mixed results. It has been suggested that negative effects of mental fatigue on cognition performance in laboratory studies could translate to impaired sport performance. However, it remains unclear if impairments in sport performance are due to mental fatigue and how mental fatigue may differ from physical fatigue. Fatigue is well understood as a complex multifactorial construct involving interactions between physiological and neuropsychological responses across brain regions. It may be prudent for researchers to return to the origins of fatigue and cognition before attempting to connect mental fatigue and sport cognition. This article reviews the concept of mental fatigue, its mechanisms and neuroanatomical basis, models of cognition relevant to sports science, investigates how mental fatigue may influence cognition, and suggests future research directions. Mental fatigue as a construct separated from fatigue could be an oversight that has hindered the development of our understanding of mental fatigue. Future sports science research could work to enhance our knowledge of our definitions of fatigue.","PeriodicalId":14439,"journal":{"name":"International journal of sports medicine","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142949019","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}

Eighteen asymptomatic men performed arm raising tasks with and without additional scapular movements, including scapular adduction and depression and scapular posterior tilt. During all tasks, the muscle activity of the upper/middle/lower trapezius and serratus anterior muscles was measured using surface electromyography; scapular upward rotation and posterior tilt angles were measured using a smartphone application. Lower trapezius muscle activity significantly increased during arm raising with scapular adduction and depression (p=0.001) or scapular posterior tilt compared to preferred arm raising (p<0.001). However, arm raising with the scapular posterior tilt showed significantly greater serratus anterior muscle activity (p=0.002) and scapular posterior tilt angle (p=0.001) together with lesser upper trapezius muscle activity (p=0.027) compared with those of scapular adduction and depression.

This study investigated the effects of body orientation, movement direction, and limb dominance on the active knee angle reproduction error. Subjects underwent active contralateral knee angle reproduction tests in a seated versus prone position, from a starting point of knee flexion versus knee extension, and with the dominant versus nondominant limb setting the target angle. The test order was randomly determined for each subject. The primary outcome was the absolute active knee angle reproduction error (°). The data of 54 healthy subjects (mean±standard deviation, age: 26±5 years, height: 174±11 cm, body mass: 69.9±14.4 kg, and Tegner activity score: 5.8±1.9) showed that the reproduction error was greater in the seated position than in the prone position. The use of the dominant limb as the reference limb was associated with significantly greater errors in the seated position, but not in the prone position. In conclusion, directly comparing the results obtained in the prone and seated positions is not recommended. However, the dominance of the reference limb might be relevant when testing patients and comparing healthy and injured knees.","PeriodicalId":14439,"journal":{"name":"International journal of sports medicine","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143467943","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}

Logistic regression was used to estimate the odds ratios and 95% confidence intervals. Athletes had experienced fractures to 54.3%. Athletes were more likely to experience fractures during training and defensive movements. Of the fractures reported, 31.9% necessitated surgical intervention. Although 65.1% of the athletes were primarily concerned about the possibility of reinjury, only 36.2% received specialized rehabilitation. The heavyweight athletes had a higher prevalence of fractures (odds ratio=2.40 and 95% confidence interval=1.17-4.90) than the lightweight athletes.

This study included 14 elite male volleyball players who participated in 95 training sessions and 18 matches. The session rating of perceived exertion and inertial measurement units were utilized to measure internal and external training loads, respectively. Biological recovery was assessed using the countermovement jump test, while social and psychological recoveries were measured through the RESTQ-Sport. Relationships were examined using linear mixed-effect models to account for repeated measures across players and time points. The results revealed that chronic external training loads negatively influenced the biological recovery, with increases in chronic external training loads associated with a longer time to take-off (β=- 0.008, p=0.03) and a reduced modified reactive strength index (β=- 0.008, p=0.047). Social recovery was influenced by internal training load metrics, with acute internal training loads increasing social stress (β=- 3.512, p=0.034). For psychological recovery, chronic internal training loads and the acute:chronic internal training load ratio were linked to higher emotional exhaustion (β=- 0.013, p=0.029; β=0.021, p<0.001, respectively). These findings highlight the critical role of external load management in the biological recovery and the relevance of subjective internal load measures in monitoring social and psychological recovery dimensions. Coaches are encouraged to integrate time-based neuromuscular metrics and perceptual load assessments into their recovery monitoring protocols to optimize athletes' well-being and performance.","PeriodicalId":14439,"journal":{"name":"International journal of sports medicine","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143414080","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}
