How can outdoor sports protect themselves against climate change-related health risks? - A prevention model based on an expert Delphi study.

OBJECTIVES: To systematically develop an adaptation model to reduce climate change-related health risks for outdoor athletes. DESIGN: Delphi Method study. METHODS: A classic asynchronous Delphi study was conducted with a total of three survey rounds. 24 experts from the eight largest outdoor sport associations by membership in the German Olympic Sports Confederation were included as well as 24 medical experts with expertise in sport medicine, internal medicine, allergology, dermatology, infectiology, or toxicology. Based on open-ended questions, panelists were asked to consider prevention measures for sport organizations and clubs. Free text responses were analyzed by qualitative content analysis according to Mayring. RESULTS: Experts recommended establishing the following eight fields of prevention measures: technical and structural measures; organizational measures; personalized measures; basic, advanced, and continuing education; concepts of action, warning concepts, and financial concepts; cooperation and coordination; campaigns; and evaluation measures. CONCLUSIONS: The pyramid model presented in this study systematizes possible sport-specific adaptation measures on climate change by empirical aggregation of knowledge from scientists, sport organizations, clubs, trainers, and professional athletes. To assess the effectiveness of these prevention measures, sport organizations may incorporate them not only into broader operations but also everyday training routines.

Analysis of a Division I Sports Medicine Program's COVID-19 Protocol: Identifying Factors that Predict Testing Demands and Positive Rates During a Pandemic.

OBJECTIVE: To determine factors indicating testing frequency and positive test results in a Division I sports department intrapandemic. DESIGN: Retrospective analysis. SETTING: A single Division I collegiate sports department. PATIENTS: All student-athlete (n = 437), student staff (n = 89), and adult staff (n = 202) members of the sports department. Total cohort (n = 728). INTERVENTIONS: The authors analyzed the independent variables of local positive rates, sport characteristics, and campus events for impact on the volume of the departmental testing and positive rates. MAIN OUTCOME MEASURES: Measured dependent variables of the volume of departmental testing and positive rates were analyzed. RESULTS: Positive predictive rates (PPRs) largely differed from local, off-campus rates in timing and duration (59.52%: P < 0.05). Overall, 20633 tests were administered with 201 positive results (0.97% PPR). Student-athlete numbers were highest in all categories, followed by adult then student staff. Greater proportions of contact sports became positive (53.03%: P < 0.001) and all-male sports (47.69%: P < 0.001). No comparative difference was seen for teams using fomites (19.15%: P = 0.403). Spring sports teams had the lowest percentage of the team positive (22.22%: P < 0.001). Winter sports had the highest PPR (1.15%), all occurring during team-controlled activities. Playing sports indoors did not increase inside team-controlled activity positive rates ( P = 0.066). CONCLUSIONS: Longitudinal changes in local, off-campus infection rates partially affected sports departmental positive results while testing rates were more influenced by sport and university schedule. Testing resources should be directed toward high-risk sports, which included contact sports (football, basketball, and soccer), all-male teams, both Winter and indoor sports inside team-controlled activities, and sports with long periods of time outside team-controlled activities.

Name, Image, and Likeness and the Health of the Young Athlete: A Call to Action for Sports Medicine Providers and the Athletic Healthcare Network.

CONTEXT: In June 2021, the National Collegiate Athletic Association (NCAA) adopted a new policy allowing NCAA athletes the opportunity to benefit and profit from their name, image, and likeness (NIL). Several state high-school associations have established policies to guide their members and students through the new era of NIL. While the potential benefits cannot be ignored, NIL presents novel responsibilities and stressors to athletes. This paper will review the paucity of literature on the effect of NIL on youth athletes and bring attention to mental health, well-being, or academic performance impacted by NIL. EVIDENCE ACQUISITION: Articles were identified through Google and PubMed search starting from NIL policy approval (June 30, 2021). Search terms included "name, image and likeness" and "NIL." STUDY DESIGN: Clinical commentary. LEVEL OF EVIDENCE: Level 5. RESULTS: Although 1 article was identified through PubMed search and numerous articles were identified through Google search, no articles directly evaluated the effects of NIL on the mental health, well-being, or academic performance of youth athletes. CONCLUSION: It is critical for sports medicine providers and other members of the athletic healthcare network to familiarize themselves with these emerging topics to best serve their patients and communities. The athletic healthcare network must be prepared to address possible NIL-related health ramifications for our patients and their families and help them navigate a confusing and predatory landscape. We must provide resources to youth athletes to minimize the risks associated with NIL involvement and related activities, and to ensure that athletes with NIL contracts are able to balance their academic and athletic responsibilities. Fostering strong relationships between stakeholders and sports medicine staff is paramount to creating an environment that permits honest discussions about NIL and the health of athletes from youth to adulthood.

Acupuncture in Sports Medicine.

Acupuncture is gaining popularity and wider acceptance as a treatment modality within the field of sports medicine. Our objective was to provide a comprehensive review of the existing literature pertaining to acupuncture in sports medicine to shed light on approaches utilized in acupuncture while revealing its personalized nature and its impact on athletes' preparation, performance, and recovery. We evaluated acupuncture research in the context of medicine and sports-related injury treatment, assessing its impact on athletic performance across demographics of athletes. Athletes participating in most sports have shown positive outcomes from acupuncture interventions. Acupuncture improves peak oxygen levels, maximum heart rate, delayed-onset muscle soreness, pain, swelling, explosive force production, and joint mobility. Furthermore, the efficacy of acupuncture appears to be similar regardless of age and sex. Lastly, the acceptance of acupuncture is influenced by cultural factors, with Western and traditional East Asian cultures exhibiting distinct perspectives on its rationale and mechanisms of action. Traditional East Asian acupuncturists typically employ qi and meridian theories in their acupuncture practices, with the recent incorporation of Western concepts. Acupuncture shows promise as an effective treatment for musculoskeletal pain and neuropathies in athletes across different age groups and for addressing injuries in various sports. Our comprehensive review will enhance our understanding of acupuncture's potential as a complementary or distinct therapeutic approach compared to conventional therapies. Additionally, our review explores its specific applications within different sports and delves into the cultural dimensions involved in integrating this practice into modern sports medicine.

Challenges and Opportunities for the Use of Patient-Reported Outcome Measures in Orthopaedic Pediatric and Sports Medicine Surgery.

Patient-reported outcome measures (PROMs) are essential tools in assessing treatment response, informing clinical decision making, driving healthcare policy, and providing important prognostic data regarding patient health status change. These tools become essential in orthopaedic disciplines, such as pediatrics and sports medicine, given the diversity of patient populations and procedures. However, the creation and routine administration of standard PROMs alone do not suffice to appropriately facilitate the aforementioned functions. Indeed, both the interpretation and optimal application of PROMs are essential to provide to achieve greatest clinical benefit. Contemporary developments and technologies surrounding PROMs may help augment this benefit, including the application of artificial intelligence, novel PROM structure with improved interpretability and validity, and PROM delivery methods that provide increased access to patients resulting in greater compliance and data acquisition yields. Despite these exciting innovations, several challenges remain in this realm that must be addressed to continue to advance the clinical usefulness and subsequent benefit of PROMs. This review will highlight the opportunities and challenges surrounding contemporary PROM use in the orthopaedic subspecialties of pediatrics and sports medicine.

Female athlete health domains: a supplement to the International Olympic Committee consensus statement on methods for recording and reporting epidemiological data on injury and illness in sport.

The IOC made recommendations for recording and reporting epidemiological data on injuries and illness in sports in 2020, but with little, if any, focus on female athletes. Therefore, the aims of this supplement to the IOC consensus statement are to (i) propose a taxonomy for categorisation of female athlete health problems across the lifespan; (ii) make recommendations for data capture to inform consistent recording and reporting of symptoms, injuries, illnesses and other health outcomes in sports injury epidemiology and (iii) make recommendations for specifications when applying the Strengthening the Reporting of Observational Studies in Epidemiology-Sport Injury and Illness Surveillance (STROBE-SIIS) to female athlete health data.In May 2021, five researchers and clinicians with expertise in sports medicine, epidemiology and female athlete health convened to form a consensus working group, which identified key themes. Twenty additional experts were invited and an iterative process involving all authors was then used to extend the IOC consensus statement, to include issues which affect female athletes.Ten domains of female health for categorising health problems according to biological, life stage or environmental factors that affect females in sport were identified: menstrual and gynaecological health; preconception and assisted reproduction; pregnancy; postpartum; menopause; breast health; pelvic floor health; breast feeding, parenting and caregiving; mental health and sport environments.This paper extends the IOC consensus statement to include 10 domains of female health, which may affect female athletes across the lifespan, from adolescence through young adulthood, to mid-age and older age. Our recommendations for data capture relating to female athlete population characteristics, and injuries, illnesses and other health consequences, will improve the quality of epidemiological studies, to inform better injury and illness prevention strategies.

Physician attitudes toward sports medicine coverage of mixed martial arts.

BACKGROUND: The popularity of modern Mixed Martial Arts (MMA) has been increasing since 2000s. It has drawn the attention of the media due to higher injury rates compared to other sports, and it is possible that this may have led to a generally negative image of MMA among viewers, including but not limited to, physicians. Therefore, our study aimed to understand the attitudes of physicians toward MMA and being asked to cover MMA events. METHODS: A cross-sectional study with an online survey was answered by 410 physicians from four physician organizations throughout the USA. Demographic data, sports event-related, sports coverage experience, athleticism, and familiarity with MMA answers were analyzed. Wilcoxon, Fisher Exact, and χ2 tests were used to compare the data. The main outcomes was the association between characteristics of physicians and attitude toward MMA coverage. RESULTS: Physician characteristics influenced positive attitudes toward MMA coverage. Those who regularly followed MMA felt more strongly that combat sport events required physician coverage, mainly for boxing (92.4% vs. 73.4%; P<0.001), kickboxing (89.9% vs. 54.7%; P<0.001), and taekwondo (50.6% vs. 38.4%; P=0.046). Doctors who considered themselves athletic or who had covered MMA events in the past were more likely to think that all sporting events should be covered by physicians (97.4% vs. 65.9%; P<0.01; 98.4% vs. 72.8%, P<0.001, respectively). Family medicine (72/139 [51.8%]) and physical medicine and rehabilitation (7/11 [63.6%]) were the specialties more inclined to agree with physician coverage for these events. CONCLUSIONS: Physicians familiar with MMA, either as a previous ringside physician or as a spectator, are more inclined to believe these events should have physician coverage as are those more experienced with sports medicine, such as family medicine and physical medicine and rehabilitation specialists. Therefore, specialized sports medicine training should be provided to allow for appropriate MMA physician coverage. With additional training, MMA event organizers should feel comfortable asking physicians in any specialty to provide sports medicine coverage to improve care for MMA athletes.

The Trade Secret Taboo: Open Science Methods are Required to Improve Prediction Models in Sports Medicine and Performance.

Clinical prediction models in sports medicine that utilize regression or machine learning techniques have become more widely published, used, and disseminated. However, these models are typically characterized by poor methodology and incomplete reporting, and an inadequate evaluation of performance, leading to unreliable predictions and weak clinical utility within their intended sport population. Before implementation in practice, models require a thorough evaluation. Strong replicable methods and transparency reporting allow practitioners and researchers to make independent judgments as to the model's validity, performance, clinical usefulness, and confidence it will do no harm. However, this is not reflected in the sports medicine literature. As shown in a recent systematic review of models for predicting sports injury models, most were typically characterized by poor methodology, incomplete reporting, and inadequate performance evaluation. Because of constraints imposed by data from individual teams, the development of accurate, reliable, and useful models is highly reliant on external validation. However, a barrier to collaboration is a desire to maintain a competitive advantage; a team's proprietary information is often perceived as high value, and so these 'trade secrets' are frequently guarded. These 'trade secrets' also apply to commercially available models, as developers are unwilling to share proprietary (and potentially profitable) development and validation information. In this Current Opinion, we: (1) argue that open science is essential for improving sport prediction models and (2) critically examine sport prediction models for open science practices.

Acute Emergent Airway Issues in Sports.

Emergent airway issues are rare in competitive sports. However, when airway compromise occurs, the sideline physician will be relied upon to manage the situation and the airway. . The sideline physician is tasked with not only the evaluation of the airway, but also management until the athlete can get to a higher level of care. Familiarity with the assessment of the airway and the various techniques for the management of airway compromise on the sideline are of the utmost importance in the unlikely event that an airway emergency should occur.

Emergency Abdominopelvic Injuries.

The presentation of traumatic abdominopelvic injuries in sport can range from initially benign appearing to hemorrhagic shock. A high clinical suspicion for injury, knowledge of the red flags for emergent further evaluation, and familiarity with the initial stabilization procedures are necessary for sideline medical providers. The most important traumatic abdominopelvic topics are covered in this article. In addition, the authors outline the evaluation, management, and return-to-play considerations for the most common abdominopelvic injuries, including liver and splenic lacerations, renal contusions, rectus sheath hematomas, and several others.

[Imaging of muscle injuries in sports medicine]. / Bildgebung von Muskelverletzungen im Sport.

BACKGROUND: Early diagnosis of muscle injuries is indispensable in order to initiate appropriate treatment and to facilitate optimal healing. PURPOSE: The aim of this review is to provide an update on imaging of muscle injuries in sports medicine with a focus on ultrasound and magnetic resonance imaging (MRI) and to present experimental approaches in addition to routine diagnostic procedures. MATERIALS AND METHODS: A PubMed literature search for the years 2012-2022 using the following keywords was performed: muscle, muscle injury, muscle imaging, muscle injury classification, delayed onset muscle soreness, ultrasound, MRI, sodium MRI, potassium MRI, ultra-high-field MRI, injuries of athletes. RESULTS: Imaging is crucial to confirm and assess the extent of sports-related muscle injuries and may help establishing treatment decisions, which directly affect the prognosis. This is of importance when the diagnosis or grade of injury is unclear, when recovery is taking longer than expected, and when interventional or surgical management may be necessary. In addition to established methods such as B­mode ultrasound and 1H­MRI, individual studies show promising approaches to further improve the imaging of muscle injuries in the future. Prior to the integration of contrast-enhanced ultrasound and X­nuclei into clinical routine, additional studies are needed to validate these techniques further. CONCLUSION: B­mode ultrasound represents an easily available, cost-effective modality for the initial diagnosis of muscle injuries. MRI is still considered the reference standard and enables an accurate morphological assessment of the extent of the injury. There are still no imaging approaches available for the objective determination of the optimal point of return to play.

Are we levelling the playing field? A qualitative case study of the awareness, uptake and relevance of the IOC consensus statements in two countries.

OBJECTIVES: Research evidence is commonly compiled into expert-informed consensus guidelines intended to consolidate and distribute sports medicine knowledge. Between 2003 and 2018, 27 International Olympic Committee (IOC) consensus statements were produced. This study explored the policy and practice impact of the IOC Statements on athlete health and medical team management in two economically and contextually diverse countries. METHODS: A qualitative case study design was adopted. Fourteen face-to-face interviews were conducted with purposively selected interviewees, seven participants from Australia (higher economic equality) and seven from South Africa (lower economic equality), representing their national medical commissions (doctors and physiotherapists of Olympic, Paralympic and Youth teams). A framework method was used to analyse interview transcripts and identify key themes. RESULTS: Differences across resource settings were found, particularly in the perceived usefulness of the IOC Statements and their accessibility. Both settings were unsure about the purpose of the IOC Statements and their intended audience. However, both valued the existence of evidence-informed guidelines. In the Australian setting, there was less reliance on the resources developed by the IOC, preferring to use locally contextualised documents that are readily available. CONCLUSION: The IOC Statements are valuable evidence-informed resources that support translation of knowledge into clinical sports medicine practice. However, to be fully effective, they must be perceived as useful and relevant and should reach their target audiences with ready access. This study showed different contexts require different resources, levels of support and dissemination approaches. Future development and dissemination of IOC Statements should consider the perspectives and the diversity of contexts they are intended for.

"Knowing the Noise That Surrounds the Athlete": A Qualitative Study Exploring the Health-Seeking Behaviors of Athletes With Limb Deficiency Drawing on the Experiences and Perceptions of the Medical Staff and Athletes.

OBJECTIVE: The aim of the study is to explore the health-seeking behaviors of athletes with limb deficiency, drawing on the experiences and perception of the sports medicine team and athletes. DESIGN: The study used an interpretive hermeneutic phenomenological methodology with a subtle realist paradigmatic view to investigate commonality in unique experiences within reality. Data collection was completed with two focus groups in December 2019 and March 2020. Thirteen participants took part including athletes and sports medicine team members (physiotherapists, doctors, and strength and conditioning coaches) working in parasports. Focus group manuscripts were transcribed verbatim from audio recordings. An inductive, iterative process was used to identify themes and subthemes, with processes in place to establish rigor. RESULTS: Two themes and five subthemes emerged in relation to the "internalization and adjustment to social identity" and "the importance and impact of factors, which impact the athlete social identity." CONCLUSIONS: Health-seeking behaviors of athletes with limb deficiency were influenced by a unique blend of personal and environmental factors that contribute toward social identity. The sports medicine team require specific awareness of factors that may diminish health-seeking behaviors to deliver a personalized approach and negate consequences.

Concussion Assessment and Management Practices Among Irish and Canadian Athletic Therapists: An International Perspective.

CONTEXT: Certified athletic therapists in Ireland and Canada serve essential concussion assessment and management roles, but their health care practices and concussion knowledge have not been established. OBJECTIVE: To examine Irish and Canadian athletic therapist cohorts' (1) concussion knowledge, (2) current concussion assessment and management techniques across all job settings, and (3) the association of concussion assessment and management practices with years of clinical experience and highest degree attained. DESIGN: Cross-sectional cohort study. SETTING: Online survey. PATIENTS OR OTHER PARTICIPANTS: Licensed Irish (49.7%, n = 91/183) and Canadian (10.1%, n = 211/2090) athletic therapists. MAIN OUTCOME MEASURE(S): Athletic therapists completed an online survey assessing their demographics, concussion knowledge (symptom recognition, patient-clinician scenarios), frequency of concussions assessed annually, and assessment and return-to-play (RTP) measures using a modified, previously validated survey. Symptom recognition consisted of 20 (8 true, 12 false) items on recognition of signs and symptoms that were scored as total correct. Descriptive statistics and odds ratios were used to examine survey responses where appropriate. RESULTS: Irish (86.8%, n = 46/53) and Canadian (93.4%, n = 155/166) athletic therapists indicated RTP guidelines were the most common method for determining RTP. Symptom recognition scores were 72.8% ± 17.0% among Irish and 76.6% ± 17.0% among Canadian athletic therapists. Irish (91.2%, n = 52/57) and Canadian (90.4%, n = 161/178) athletic therapists reported standardized sideline assessments as the most used concussion assessment method. Irish and Canadian athletic therapists' use of 2-domain (Irish: 38.6% [n = 22/57]; Canadian: 73.6% [n = 131/178]) and 3-domain (Irish: 3.5% [n = 2/57]; Canadian: 19.7% [n = 35/178]) minimum assessments (ie, symptoms, balance, or neurocognitive) was not associated with education or clinical experience (P ≥ .07), except for Canadian athletic therapists with master's degrees having greater odds of completing 2-domain assessments at initial evaluation than those with bachelor's degrees (odds ratio = 1.80; 95% CI = 1.41, 1.95). CONCLUSIONS: Irish and Canadian athletic therapists demonstrated similar concussion knowledge; however, most did not fully adhere to international consensus guidelines for concussion assessment as evidenced by low 2- and 3-domain assessment use. Athletic therapists should aim to implement multidimensional concussion assessments to ensure optimal health care practices and patient safety.

Assessing Performing Artists in Medical and Health Practice - The Dancers, Instrumentalists, Vocalists, and Actors Screening Protocol.

ABSTRACT: Training in the performing arts exposes individuals to often extreme physical and psychological demands, which are linked to high occupational injury rates. The intense demands of performing artists have been likened to those of sport athletes. However, distinct differences in these demands necessitate specialized approaches to the health care of performing artists. Through the Athletes and the Arts collaboration, the American College of Sports Medicine and Performing Arts Medicine Association identified that the creation of a specialized preparticipation screening tool for performing artists would likely enhance health care for performing artists significantly. Based on a thorough review of established assessments and an extensive consultation process with domain experts, a consensus best-practice screening tool was developed: the Dancer, Instrumentalist, Vocalist, Actor (DIVA) Preparticipation Screening. This screening tool is modeled on the athletic preparticipation examination (PPE) in its structure and 30-min target duration. However, DIVA diverges considerably from the PPE in its content to address the specific risks and needs of performing artists. In particular, screening questions and physical examination procedures focus strongly on musculoskeletal injuries and mental health conditions, in response to the preponderance and interactions of these conditions appearing in performing artists. The DIVA tool presented is intended as a "living tool," which can be modified in the future to include new effective assessment techniques as appropriate. Training in the DIVA preparticipation physical examination is included as a core component of the essentials of performing arts medicine continuing education course described in detail in a companion manuscript in this issue.

'It's All Downhill from Here': A Scoping Review of Sports-Related Concussion (SRC) Protocols in Downhill Mountain Biking (DHI), with Recommendations for SRC Policy in Professional DMB.

INTRODUCTION: Downhill mountain biking (DHI) is a form of cycling and does not currently have a specific sports-related concussion (SRC) assessment. OBJECTIVE: To review the extent, range and nature of research investigating SRC in DMB, provide a summary of key literature findings relating to its identification and management, and then develop a SRC protocol specific to DMB. DESIGN: Scoping review as per recognised methods. SETTING: Literature-based. The following databases were searched: MEDLINE, EMBASE, Scopus and Web of Science, with no restrictions on date. Results were limited to the English language. PARTICIPANTS: Six articles were included in the review from 64 identified articles. The article had to specifically include an analysis of adult downhill riders for inclusion. OUTCOME MEASURES: Study type, study group (amateur/professional), concussion incidence, concussion assessment and recommendations. MAIN RESULTS: Concussion incidence was identified as between 5-23%. No study outlined a trackside assessment of cyclists or a protocol for return to play where SRC was identified. Several authors identified that riders often continued to participate despite the presence of a concussion. No sport-specific SRC assessment was determined for DHI, and a SRC assessment was therefore developed. CONCLUSIONS: This review illustrates the lack of studies and formal protocol in SRC assessment for DHI. In light of this, we propose a three-stage framework specific to the sport to best identify a concussion and act where appropriate while minimising disruption to competition. This framework involves assessing the cyclist on the 'sideline', a second assessment post-event in the medical room and a third assessment the following day. A SRC consensus meeting specific for DHI is suggested with an identified need for updated guidance from UCI, requiring possible rule changes for the sport.

Cardiac screening prior to return to play after SARS-CoV-2 infection: focus on the child and adolescent athlete: A Clinical Consensus Statement of the Task Force for Childhood Health of the European Association of Preventive Cardiology.

Cardiac sequelae after COVID-19 have been described in athletes, prompting the need to establish a return-to-play (RTP) protocol to guarantee a safe return to sports practice. Sports participation is strongly associated with multiple short- and long-term health benefits in children and adolescents and plays a crucial role in counteracting the psychological and physical effects of the current pandemic. Therefore, RTP protocols should be balanced to promote safe sports practice, particularly after an asymptomatic SARS-CoV-2 infection that represents the common manifestation in children. The present consensus document aims to summarize the current evidence on the cardiac sequelae of COVID-19 in children and young athletes, providing key messages for conducting the RTP protocol in paediatric athletes to promote a safe sports practice during the COVID-19 era.

Limited diagnostic value of questionnaire-based pre-participation screening algorithms: a "risk-exposed" approach to sports activity.

BACKGROUND: Several pre-participation screening algorithms (PPSAs) have been proposed to assess sports eligibility in different populations. They are usually based on self-administered questionnaires, without further medical assessment if no risk factors are documented. The Med-Ex "Formula Benessere" worksite program includes a complete cardiovascular (CV) screening for all participants. The purpose of this study was to assess PPSAs accuracy in detecting medical and/or CV abnormalities in the general population, comparing the results with the date derived from Med-Ex program. METHODS: The Med-Ex medical evaluation, consisting of medical history, physical examination (including body composition), resting electrocardiogram (ECG) and exercise stress test in 464 male subjects (38.4 aged) was analyzed and matched to several PPSAs - Physical Activity Readiness Questionnaire (PAR-Q) (2002-2020), American Heart Association (AHA)/American College of Sport Medicine (ACSM) (1998-2009-2014-2015), European Association of Cardiovascular Prevention and Rehabilitation (EACPR) (2011) - retrospectively simulated. RESULTS: Five-hundred and 67 abnormalities were detected though Med-Ex medical evaluation, and one-fourth (24%) would have been undetected applying PPSA alone. In particular 28% of high blood pressure, 21% of impaired fasting glycaemia, 21% of high Body Mass Index (BMI) values and 19% of ECG abnormalities would have been missed, on average, by all PPSAs. CONCLUSIONS: The simulation analysis model performed in this study allowed to highlight the limits of PPSAs in granting sport eligibility, compared to a medical-guided CV screening. These findings emphasize the importance of a more balanced approach to pre-participation screening that includes a thorough evaluation of the cost/benefit ratio.

The measurement of neck strength: A guide for sports medicine clinicians.

This masterclass aims to provide an overview of the measurement of neck strength and the factors which can increase the ecological validity of the testing protocol within an athletic population. Adopting a 'gold standard' method for measuring neck strength is of vital importance when determining strength differences across sports, ages and sexes. Without a 'gold standard' method current variations in testing procedure and equipment have created challenges in establishing normative neck strength data. With encouraging evidence that higher neck strength can have a protective effect against sports-related head and neck injuries, including concussion, new injury prevention knowledge may be impeded by a lack of consensus on how to accurately measure neck strength, with a number of different methods available. This masterclass will outline the factors clinicians should consider when selecting a device and measurement protocol when measuring maximal neck strength as well as how to interpret the results.
