Studies reporting the injury IR in basketball players calculated using the number of athletes exposures (AEs) and/or exposure hours were eligible for inclusion.RESULTSFollowing screening, 22 studies (15 reporting mechanism data, 21 reporting body location data, and 17 reporting type data) were included in the systematic review and meta-analysis. Player contact (42.9%) and non-contact (25.0%) were the most common injury mechanisms, with IRs of 0.156 and 0.093 per 100 AEs. Ankle injuries (25.8%, IR = 0.075 per 100 AEs) and knee injuries (15.5%, IR = 0.046 per 100 AEs) accounted for 41.3% of reported injuries. The most common injury types were ligament sprains (IR = 0.102 per 100 AEs) followed by muscle/tendon strains (IR = 0.037 per 100 AEs) and concussions (IR = 0.028 per 100 AEs). A concerning finding was the proportion of head and facial injuries (16.3%), particularly among female players. Female players displayed significantly higher IR of ball contact injuries, knee injuries, dislocations/subluxations, and concussions compared with male players. Injury IR was consistently higher in games than practice settings, as well as in collegiate compared with high-school players.CONCLUSIONSThis study provides comprehensive and contemporary analyses of one of the most investigated areas in the basketball literature, injury IR. The provided results may inform the development of preventive measures to mitigate injury risk considering the notable factors identified.","PeriodicalId":21969,"journal":{"name":"Sports Medicine","volume":"39 1","pages":""},"PeriodicalIF":9.8,"publicationDate":"2025-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145288499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Research has demonstrated that SCS can ameliorate motor and autonomic cardiovascular dysfunctions, particularly in individuals with spinal cord injury (SCI). Notably, SCS has been shown to augment aerobic exercise performance. Owing to the nature of their injury, athletes with SCI are often predisposed to low resting blood pressure and impaired physiological responses to exercise. Therefore, some athletes intentionally induce autonomic dysreflexia (\"boosting\") to gain a competitive advantage - an act banned by the International Paralympic Committee (IPC). However, the emergence of electroceuticals facilitates an alternative performance enhancement strategy that could be considered unfair without equal access opportunities for all athletes. Currently, the World Anti-Doping Agency and the IPC have not acknowledged the potential impact of electroceuticals in parasport. Herein, we present an argument that the use of SCS meets the criteria for it to be placed on the World Anti-Doping Code Prohibited List (or at the very least be monitored) because collectively: SCS can enhance sport performance, represents a potential health risk to the athlete if misused, and may violate the spirit of sport. Acute and chronic use of SCS may also lead to classification changes, and increased opportunities for athletes to intentionally misrepresent, thereby raising concerns for the IPC. The growing access to electroceuticals (e.g. via clinical trial participation or private healthcare implantation) more than ever increases the likelihood of an athlete using SCS to gain an unfair advantage in parasport.","PeriodicalId":21969,"journal":{"name":"Sports Medicine","volume":"572 1","pages":""},"PeriodicalIF":9.8,"publicationDate":"2025-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145277204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hypoxia conditioning is broadly categorized into systemic (i.e., exposure to terrestrial or normobaric hypoxia) or localized (ischemic preconditioning, blood flow restriction training) approaches and could represent a viable option to increase exercise tolerance of load-compromised athletes.PURPOSEThis review evaluates the potential of hypoxia conditioning as a training and rehabilitation tool for load-compromised athletes. It explores its applications across various rehabilitation stages and key para-athlete sub-groups including spinal cord injury, limb deficiency, and cerebral palsy.EVIDENCEPassive hypoxia conditioning strategies using external limb compression help maintain musculoskeletal function during early rehabilitation stages involving immobilization or minimal loading. As rehabilitation progresses, both systemic and localized hypoxia conditioning (i.e., blood flow restricted exercise) effectively modulates external load while maintaining adequate (internal) physiological strain to induce beneficial cardiometabolic or musculoskeletal adaptations with lower mechanical stress. Para-athletes facing challenges such as biomechanical limitations, reduced active muscle mass, or muscle weakness can benefit from hypoxia conditioning's capacity to enhance muscle aerobic function, promote muscle strength and hypertrophy, and improve cardiorespiratory performance at lower mechanical loads.CONCLUSIONHypoxia conditioning emerges as a promising intervention to potentially overcome the physical and physiological challenges faced by load-compromised athletes. By addressing their specific limitations, hypoxia conditioning can optimize rehabilitation and training outcomes. Future research is essential to refine hypoxia conditioning protocols and tailor them to maximize individual adaptability and performance across diverse load-compromised athlete populations.","PeriodicalId":21969,"journal":{"name":"Sports Medicine","volume":"1 1","pages":""},"PeriodicalIF":9.8,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145194700","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A broad overview could help clarify the work demands and responses of staff in this field.OBJECTIVESThis scoping review aims to provide an overview of the literature on staff working in high-performance sport with roles and responsibilities related to athlete operations and/or performance. Using theoretical frameworks to operationally define key concepts, the review maps relevant studies and summarizes findings on work demands, resources, coping strategies, and responses in high-performance sport.METHODSA scoping review was conducted and reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). Searches were performed across three electronic databases, PubMed, PsycINFO, and SPORTDiscus, to identify relevant studies published up to 1 August 2024. The search strategy employed terms related to working in high-performance sport and was structured using the population, exposure, and outcome framework. Studies examining staff working full-time in high-performance sport and assessing work demands, responses, resources, or coping strategies were included. This review was registered with the Open Science Framework ( osf.io/br9hm/ ).RESULTSElectronic and manual searches identified 124 studies meeting the inclusion criteria.

This review included prospective and retrospective studies reporting injury incidence or prevalence among football match officials, with a study period of at least one season. Studies needed to specify injury definitions and include data on injury location, type, mechanism, or severity. Both male and female officials were eligible. Systematic reviews, commentaries, and letters were excluded. Study quality and risk of bias were evaluated using the STROBE-SIIS, in addition to the Newcastle-Ottawa Scale and funnel plots. Injury incidence rates were estimated using a random effects Poisson regression, accounting for heterogeneity and moderators. Heterogeneity was assessed with the I2 statistic.RESULTSA total of 17 studies were included, encompassing 3621 referees. The most frequent injuries were strains and sprains in the knee and ankle. The overall injury incidence was 2.19 injuries per 1000 h of exposure (95% CI 1.30-3.69). On-field referees experienced an incidence rate of 1.46 injuries per 1000 h of exposure (95% CI 0.76-2.81), while assistant referees had a lower rate of 0.84 per 1 h of exposure (95% CI 0.36-1.97).

Players underwent 3D dental scans and were provided with custom-fit iMGs. The iMGs contained an accelerometer and gyroscope that sampled at 3200 Hz with measured ranges of ± 200 g and ± 35 rad/s. The iMGs recorded peak linear acceleration (PLA), peak angular acceleration (PAA) and peak angular velocity (PAV). Data were collected from academy matches (254 player-matches; 241 h of exposure) and international matches (114 player-matches; 118.2 h of exposure). Descriptive statistics (median, interquartile range [IQR], 95th percentile and peak values) were calculated to characterise HAE magnitude across positions and competition levels. Negative binomial regressions assessed incidence rates across teams, positions and thresholds, adjusting for exposure time.RESULTSA total of 6508 HAEs were recorded across 368 player matches from club U21 and national U20 rugby players. Median and peak values for linear acceleration, angular acceleration and change in angular velocity were generally higher in club players, particularly in the front row and outside backs. Club outside backs demonstrated the highest PLA (72.8 g) and PAA (5740 rad/s2), while the club front row reached the highest PLA (81.8 g) and PAA (8034 rad/s2) overall.

While mental health in sports has received increased attention, the mental health of sporting officials-such as judges, referees, and umpires-remains significantly under-researched compared with athletes. To our knowledge, there are no systematic reviews and meta-analyses that have synthesised available prevalence data of mental health symptoms and disorders in sporting officials. In addition, while previous reviews have provided a broad overview of risk and protective factors in relation to overall mental health, links between identified factors and specific mental health and well-being outcomes have not been explored. Therefore, this study aimed to systematically review and analyse the prevalence rates of mental health symptoms and disorders (e.g., depression and anxiety) among sporting officials and identify specific risk and protective factors influencing sporting officials' mental health and/or psychological well-being.METHODSRelevant studies were retrieved from SCOPUS, Web of Science, SPORTDiscus and PsycINFO up until July 2025. Prevalence rates of specific mental health outcomes (i.e. anxiety and depressive symptoms) were meta-analysed.RESULTSA total of 26 studies were included. Meta-analyses comprising 2797 sporting officials showed that the pooled proportion of elevated anxiety symptoms was 19.1% (95% CI 13.4-27, I2 = 94.1%) and 20.6% (95% CI 12.4-32.3, I2 = 97.3%) for elevated symptoms of depression. Sport-environmental risk factors were identified in 70% of the studies (k = 19) (e.g., levels of professional experience, environment around matches, experiences of abuse), while 48% of studies (k = 13) examined personal risk factors (e.g., age, sex, injury). A total of 37% of studies (k = 10) examined sport-environmental protective factors (e.g., years of officiating experience, level of officiating, hours and frequency of officiating), while 33% of studies (k = 9) investigated personal protective factors (e.g., emotional intelligence, feelings of competence, age, sex).CONCLUSIONSThe results suggest that targeting change at various levels of the sport ecosystem may help foster and promote positive mental health outcomes among sporting officials. The findings of this review suggest that strategies tailored to officials could include age/level of experience-specific support interventions and creating organisational cultures that prioritise mental health outcomes.","PeriodicalId":21969,"journal":{"name":"Sports Medicine","volume":"17 1","pages":""},"PeriodicalIF":9.8,"publicationDate":"2025-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145153390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
