Objective: Health disparities are widely prevalent; however, little has been done to examine and address their causes and effects in sports and exercise medicine (SEM). We aimed to summarise the focus areas and methodology used for existing North American health disparity research in SEM and to identify gaps in the evidence base., Design: Scoping review., Data Sources: Systematic literature search of PubMed, Scopus, SPORTDiscus, CINAHL Plus with Full Text, Web of Science Core Collection and Cochrane Central Register of Controlled Trials., Eligibility Criteria: Full-text, peer-reviewed manuscripts of primary research, conducted in North America; published in the year 2000 or after, in English; and focusing on organised sports were included., Results: 103 articles met inclusion criteria. Articles were classified into five focus areas: access to and participation in sports (n=45), access to SEM care (n=28), health-related outcomes in SEM (n=24), provider representation in SEM (n=5) and methodology (n=1). Race/ethnicity (n=39), socioeconomic status (n=28) and sex (n=27) were the most studied potential causes of health disparities, whereas sexual orientation (n=5), location (rural/urban/suburban, n=5), education level (n=5), body composition (n=5), gender identity (n=4) and language (n=2) were the least studied. Most articles (n=74) were cross-sectional, conducted on youth (n=55) and originated in the USA (n=90)., Conclusion: Health disparity research relevant to SEM in North America is limited. The overall volume and breadth of research required to identify patterns in a heterogeneous sports landscape, which can then be used to inform positive change, need expansion. Intentional research focused on assessing the intersectionality, causes and consequences of health disparities in SEM is necessary., Competing Interests: Competing interests: SAK, YAT-W and AR are associate editors for BJSM., (© Author(s) (or their employer(s)) 2024.

Background: Arthralgia or joint pain is a heterogeneous condition including organic and nonorganic joint pain. It is common in older populations, particularly in females. There is evidence that menopausal changes are associated with increased prevalence of arthralgia. While physical activities have been recommended to mitigate osteoarthritis (OA) and arthralgia, sport participation also carries risk factors due to excessive loading of some joints and possible injuries. The aim was to evaluate the association of training patterns, prior injuries, and severity of menopausal symptoms with arthralgia in female Masters weightlifters., Methods: Competitive female Masters weightlifters (n=868, 30-78 years) from 30 countries completed an online survey including joint pain for different anatomical sites, weightlifting training and performance, sport history, and menopausal symptoms. Logistic regression models were used to estimate the association of training patterns, prior sport participation, and menopausal symptom severity with arthralgia separately for shoulders, spine, hips, knees, ankles, elbows, and hands., Results: Arthralgia was most reported in knees (38.8%), shoulders (29.8%), hands/wrists (28.8%), and hips (24.9%). The prevalence of arthralgia was 51.5% in pre-menopausal women, 62.4% in women post natural menopause and 73.3% in women post medical or surgical menopause. Lifting heavier weights was associated with arthralgia in hips (OR=1.05, p=0.03), knees (OR=1.06, p=0.01), and hands/wrists (OR=1.05, p=0.04), but prior strength training was protective for arthralgia in the shoulders (OR=0.66, p=0.02). Prior injuries and psychological menopausal symptom severity were associated with an increased risk for arthralgia (p<0.01)., Conclusions: Arthralgia was common in competitive female weightlifters. Training frequency was not associated with arthralgia, but lifting heavier weights relative to age and body mass was. Prior injuries and menopausal symptoms were associated with arthralgia, but prior strength training was protective of arthralgia in the shoulders. Athletes, coaches and sports medicine professionals should be aware that prevalence of polyarthralgia increases in post-menopausal athletes., (© 2023. BioMed Central Ltd., part of Springer Nature.)

The Ehlers-Danlos syndromes (EDS) comprise a group of inherited connective tissue disorders presenting with features of skin hyperextensibility, joint hypermobility, abnormal scarring and fragility of skin, blood vessels and some organs. The disease is generally diagnosed through the cluster of clinical features, though the addition of genetic analysis is the gold standard for diagnosis of most subtypes. All subtypes display skin manifestations, which are essential to the accurate clinical diagnosis of the condition. Furthermore, cutaneous features can be the first and/or only presenting feature in some cases of EDS and thus understanding these signs is vital for diagnosis. This review focuses on particular cutaneous features of each EDS subtype and their clinical importance. Provision of a specific diagnosis is important for management, prognosis and genetic counselling, often for family members beyond the individual., Competing Interests: All authors of this manuscript certify that they have no affiliations with or involvement in any organization of entity with any financial interest or other equity interest or non‐financial interest in the materials discussed in this manuscript., (© 2022 The Authors.

Abstract: Bush, CM, Wilhelm, AJ, Lavallee, ME, and Deitch, JR. Early sport specialization in elite weightlifters: weightlifting injury occurrence and relevant opinions. J Strength Cond Res 35(11): 3260-3264, 2021-Sports specialization has been associated with increased injury and burnout. This study sought to determine the age, rate of injury, influence to specialize, and opinions surrounding the impact of sports specialization in attainment of elite-level weightlifting status. A link to an anonymous survey was distributed to the top 20 weightlifters in each weight class (8 male and 7 female weight classes). The survey questioned athletes about both age and motivation to specialize, previous injuries and/or surgeries, and level of competition. Injuries and surgeries were compared between those who specialized at the Youth level (≤age 16), Junior level (ages 17-20), and nonspecialized weightlifters. One hundred forty-one athletes (47.0%) completed the survey. Sixteen subjects (11.3%) specialized at the Youth level, 18 (12.8%) specialized at the Junior level, and the remaining 107 (75.9%) did not specialize before age 21. There was a statistically significant difference in the occurrence of injury before age 21 between weightlifters specializing at the Youth level and those who did not specialize (Χ2(1) = 22.4, p < 0.0001). There were no statistically significant differences in serious injury after age 21 between groups. Weightlifters cited primarily themselves (45.4%) or coach (43.1%) as a driving influence to specialize. The majority of athletes (68.8%) felt that specializing during the Youth age group was not necessary to achieve elite status. Despite a relatively small sample size, injuries occurred more frequently in weightlifters specializing at younger ages, suggesting that risks associated with early sport specialization also apply to weightlifters. These risks should be considered before implementing an early specialization training regimen., (Copyright © 2019 National Strength and Conditioning Association.)

The Ehlers-Danlos syndromes (EDS) are a clinically and genetically heterogeneous group of heritable connective tissue disorders (HCTDs) characterized by joint hypermobility, skin hyperextensibility, and tissue fragility. Over the past two decades, the Villefranche Nosology, which delineated six subtypes, has been widely used as the standard for clinical diagnosis of EDS. For most of these subtypes, mutations had been identified in collagen-encoding genes, or in genes encoding collagen-modifying enzymes. Since its publication in 1998, a whole spectrum of novel EDS subtypes has been described, and mutations have been identified in an array of novel genes. The International EDS Consortium proposes a revised EDS classification, which recognizes 13 subtypes. For each of the subtypes, we propose a set of clinical criteria that are suggestive for the diagnosis. However, in view of the vast genetic heterogeneity and phenotypic variability of the EDS subtypes, and the clinical overlap between EDS subtypes, but also with other HCTDs, the definite diagnosis of all EDS subtypes, except for the hypermobile type, relies on molecular confirmation with identification of (a) causative genetic variant(s). We also revised the clinical criteria for hypermobile EDS in order to allow for a better distinction from other joint hypermobility disorders. To satisfy research needs, we also propose a pathogenetic scheme, that regroups EDS subtypes for which the causative proteins function within the same pathway. We hope that the revised International EDS Classification will serve as a new standard for the diagnosis of EDS and will provide a framework for future research purposes. © 2017 Wiley Periodicals, Inc., (© 2017 Wiley Periodicals, Inc.)

Classical EDS is a heritable disorder of connective tissue. Patients are affected with joint hypermobility, skin hyperextensibilty, and skin fragility leading to atrophic scarring and significant bruising. These clinical features suggest consideration of the diagnosis which then needs to be confirmed, preferably by genetic testing. The most recent criteria for the diagnosis of EDS were devised in Villefranche in 1997. [Beighton et al. (1998); Am J Med Genet 77:31-37]. The aims set out in the Villefranche Criteria were: to enable diagnostic uniformity for clinical and research purposes, to understand the natural history of each subtype of EDS, to inform management and genetic counselling, and to identify potential areas of research. The authors recognized that the criteria would need updating, but viewed the Villefranche nosology as a good starting point. Since 1997, there have been major advances in the molecular understanding of classical EDS. Previous question marks over genetic heterogeneity have been largely surpassed by evidence that abnormalities in type V collagen are the cause. Advances in molecular testing have made it possible to identify the causative mutation in the majority of patients. This has aided the further clarification of this diagnosis. The aim of this literature review is to summarize the current knowledge and highlight areas for future research. © 2017 Wiley Periodicals, Inc., (© 2017 Wiley Periodicals, Inc.)

Context: Nutritional supplements advertised as ergogenic are commonly used by athletes at all levels. Health care professionals have an opportunity and responsibility to counsel athletes concerning the safety and efficacy of supplements on the market., Evidence Acquisition: An Internet search of common fitness and bodybuilding sites was performed to identify supplement promotions. A search of MEDLINE (2000-August, 2011) was performed using the most commonly identified supplements, including glutamine, choline, methoxyisoflavone, quercetin, zinc/magnesium aspartate, and nitric oxide. The search terms supplement, ergogenic aid, and performance were also used., Results: Six common and newer supplements were identified, including glutamine, choline, methoxyisoflavone, quercetin, zinc/magnesium aspartate, and nitric oxide., Conclusions: Controlled studies have not determined the effects of these supplements on performance in athletes. Scientific evidence is not available to support the use of these supplements for performance enhancement.

The following musculoskeletal ultrasound (MSK US) curriculum was developed by the American Medical Society for Sports Medicine (AMSSM) to provide a pathway by which a sports medicine fellow can obtain adequate MSK US training during their fellowship to meet the requirements of competency outlined by the American Institute of Ultrasound in Medicine (AIUM) Training Guidelines for the Performance of MSK US Examination. Many fellowship programmes may not be able to follow all of the recommendations outlined by this document owing to their available resources. However, this curriculum can be used as a suggested/potential guideline for MSK US training within a sports medicine fellowship, and may assist programmes in developing or modifying their own internal training methods.

This article introduces the history of strength training, explains the many different styles of strength training, and discusses common injuries specific to each style. Strength training is broken down into five disciplines: basic strength or resistance training, bodybuilding, power lifting, style-dependant strength sports (e.g., strongman competitions, Highland games, field events such as shot put, discus, hammer throw, and javelin), and Olympic-style weightlifting. Each style has its own principal injuries, both acute and chronic, related to the individual technique. Acute injuries should be further categorized as emergent or nonemergent. Specific age-related populations (i.e., the very young and the aging athlete) carry additional considerations.

Medial tibial stress syndrome (MTSS), commonly known as "shin splints," is a frequent injury of the lower extremity and one of the most common causes of exertional leg pain in athletes (Willems T, Med Sci Sports Exerc 39(2):330-339, 2007; Korkola M, Amendola A, Phys Sportsmed 29(6):35-50, 2001; Hreljac A, Med Sci Sports Exerc 36(5):845-849, 2004). Although often not serious, it can be quite disabling and progress to more serious complications if not treated properly. Often, the cause of MTSS is multi-factorial and involves training errors and various biomechanical abnormalities. Few advances have been made in the treatment of MTSS over the last few decades. Current treatment options are mostly based on expert opinion and clinical experience. The purpose of this article is to review published literature regarding conservative treatment options for MTSS and provide recommendations for sports medicine clinicians for improved treatment and patient outcomes.

Ehlers-Danlos syndrome (EDS) should be considered in the evaluation of the hypermobile athlete. EDS is a group of inheritable connective tissue disorders affecting collagen and is characterized by articular hypermobility, skin extensibility, and tissue fragility. The most common findings in the active athlete are joint pain or instability, tissue fragility, or joint dislocations. Other common findings include "cigarette paper" scarring over bony prominences, pes planus, mitral valve prolapse, hyperelastic thin skin, and internal organ involvement. The vascular type has an increased risk of sudden death secondary to catastrophic events such as aortic or visceral rupture. Although there are some genetic laboratory tests currently available, a careful history and physical examination are most helpful in diagnosing athletes with this disorder. Previous classification systems were confusing, but the 1997 revised nosology simplified the classification of EDS into six types (three major, three minor). Preparticipation cardiothoracic and orthopedic screening is highly recommended for athletes with EDS, and appropriate cardiovascular, orthopedic, gastrointestinal, neurologic, and dermatologic management can often allow patients with EDS to remain active.

Testicular torsion is described as the twisting of the spermatic cord resulting in acute pain and ischemia. This has a tendency to occur more frequently during adolescence and its cause is unknown. The most common signs and symptoms include red, swollen scrotum and acutely painful testicle, often in the absence of trauma. Nausea and vomiting are common. The most common conditions in the differential diagnosis include epididymitis, strangulated inguinal hernia, traumatic hematoma, testicular tumor, or testicular fracture. Physical examination techniques such as scrotal elevation can be helpful in differentiating between epididymitis and testicular torsion, but emergent imaging with Doppler ultrasound seems to be the most helpful in confirming the diagnosis. Radionuclide testicular scintigraphy with 99mTc is helpful when past the acute phase (the first 12 hours) and vascular compromise has prolonged. The clinician may attempt to manually reduce the torsion, but many need to be immediately referred to a urologist for a surgical exploration. Long-term prognosis for a functional, nonatrophied testicle is improved the sooner the torsion is diagnosed and treated.
