Adversity and Resiliency: Athlete Experiences within U.S. College Sport

Research regarding the benefits and detriments of the U.S. collegiate sport governance structure are mixed. Guided by Richardson’s Resiliency Theory (2002), former athletes (n = 215) revealed specific themes of adversity experienced during college with the most prevalent including injury, time demands, and coach-athlete tension. Through interview, athletes noted adversity promoted their resiliency, facilitated grit/perseverance, enhanced teamwork and time management skills, and led to other forms of growth. This study extends our understanding of the long-term impacts of competitive sport participation in this context. This understanding is important for administrators seeking to maximize participant experiences and emulate, enhance, or reform the U.S. College Sport governance model.

Epidemiology of Sports-Related Tendon Ruptures Presenting to Emergency Departments in the United States

Background: Participation in recreational and competitive sports can predispose people to musculoskeletal injuries. Chronic overuse with insufficient recovery, overloading, and direct contact can result in acute primary tendon ruptures. There is scarce literature regarding the epidemiology of sports-related acute primary tendon ruptures in the United States (US). Purpose: To identify the incidence rate (IR) of sports-related acute primary tendon ruptures presenting to US emergency departments using the National Electronic Injury Surveillance System (NEISS) database and describe the trends in the IR from 2001 to 2020. Study Design: Descriptive epidemiology study. Methods: The NEISS database was queried using injury case narratives; cases with a clear diagnosis of an acute primary tendon rupture were included in the final analysis. National estimates, estimated IRs (reported as per 1,000,000 person-years at risk), and temporal trends in the annual IR (reported as average annual percent change) of acute primary tendon ruptures were calculated using NEISS sample estimates and US Census Bureau population estimates. Results: An estimated total of 141,382 patients (95% confidence interval [CI], 107,478-175,286) presented to US emergency departments with a sports-related tendon rupture over the study period (IR, 22.9 person-years at risk [95% CI, 17.4-28.3]). The mean age was 37.7 years (95% CI, 37.0-38.5). Of all cases of a tendon rupture identified from 2001 to 2020, 60.1% were secondary to exercise/sports-related injury mechanisms. An Achilles tendon rupture was the most common injury, representing 55.9% of cases. Basketball was the most common sports-related injury mechanism, accounting for 36.6% of cases. The overall injury rate in male patients was 7.7 times that of female patients (IR ratio, 7.7 [95% CI, 4.4-13.5]; P < .05). The annual incidence of all sports-related tendon ruptures in the US increased significantly from 2001 to 2020 (average annual percent change, 1.9 [95% CI, 1.0-2.8]; P < .01). Conclusion: Recreational/competitive sports participation accounted for a large proportion of acute primary tendon ruptures in the US during the study period.

Cardiopulmonary Fitness and Personalized Exercise Prescription in Patients With Hypertrophic Cardiomyopathy.

Patients with hypertrophic cardiomyopathy (HCM) are generally restricted regarding participation in competitive sports based on the potential risk of sudden cardiac death and malignant arrhythmias. As a result, they are often inactive and experience the negative consequences of a sedentary lifestyle. Hence, the need arises to strike the right balance between these 2 extremes through personalized exercise prescription. The aims of this study were (1) to assess the characteristics of patients with HCM practicing regular aerobic physical activity compared with sedentary patients; (2) to perform a personalized moderate-intensity exercise prescription and evaluate its effects. Patients with HCM were evaluated through clinical assessment, ECG, ambulatory ECG monitoring, echocardiography, and cardiopulmonary testing. A personalized moderate-intensity exercise prescription was performed, and the same investigations were repeated. Physically active patients with HCM demonstrated better cardiopulmonary functional capacity than sedentary patients (oxygen consumptionpeak/kg 32.9±7.4 versus 25.2±7.4 mL/min per kg P≤0.0001, ventilation/carbon dioxide production slope 26.7±4.3 versus 29.9±5.2 P=0.004), with similar prevalence of ventricular arrhythmias (P=0.43). Sedentary subjects showed a borderline higher prevalence of obesity (P=0.07) than physically active subjects. Moderate-intensity exercise prescription led to improved cardiopulmonary fitness without occurrence of adverse events. Patients with HCM practicing regular aerobic exercise have a better functional capacity in the absence of relevant events than sedentary patients. Conversely, a sedentary lifestyle led to a deterioration of cardiopulmonary functional capacity and fitness. The tailored moderate-intensity personalized exercise prescription appears to be a feasible approach in carefully selected patients with HCM to counterbalance the negative effects of sedentary behavior without significant major events.

“Sport Belongs to Everyone… But Not During Pregnancy”: Views of Finnish Sport Stakeholders on Pregnancy in Sport

The social construction of pregnancy emphasizes the mother’s responsibility for the developing fetus. Hence, certain activities, such as participation in competitive sport, are often constructed as inappropriate during pregnancy. While expert opinion tends to stress caution, the diversity of athlete mothers’ experiences challenge these dominant discourses. Less is known about how peers and other stakeholders in sport view the participation of pregnant athletes. Knowledge of such attitudes is essential to understanding the position of women in a specific society and the barriers to their autonomy. Hence, we examined survey responses from different sport stakeholders (N = 540) in Finland. Drawing on relational dialectics theory (Baxter, L. A. (2011). Voicing relationships. Sage.), we used contrapuntal analysis to identify different discourses on the compatibility of pregnancy and sport, and their interplay. Three discourses were identified: an equality discourse, which emphasizes that sport belongs to everyone, and that pregnant people should be accepted and supported in sporting environments; a responsibility discourse, which constructs pregnancy as fragility and sport as potentially dangerous for the athlete and the fetus; and an incompatibility discourse, which constructs pregnancy as a disease and unacceptable in sporting environments. Our analysis shows that medicalized, authoritative knowledge is the master strategy used to keep women out of male social spaces during pregnancy. The findings of our study highlight the ongoing struggle for reproductive justice in a patriarchal world order. To advance women’s position in society and support the autonomy of all individuals, viable professional guidelines and organizational policies must be formulated and applied.

Exercise, Sports Participation, and Quality of Life in Young Patients with Heritable Thoracic Aortic Disease.

Patients with heritable thoracic aortic disease (HTAD)are often restricted from sports and certain types of exercise. This study was designed to investigate the effect of lifetime exercise exposure and competitive sports participation on quality of life (QOL) in patients aged 15-35 with syndromic [Marfan syndrome (MFS), Loeys-Dietz syndrome (LDS), vascular Ehlers-Danlos syndrome (vEDS)] and non-syndromic heritable thoracic aortic disease (nsHTAD). This cross-sectional study employed questionnaires to assess lifetime exercise exposure and utilized the PedsQL QOL Inventory. We developed an Exercise Exposure Score (EES) to quantify lifetime exercise exposure. Questionnaires were completed via telephone with complimentary medical record review. Forty patients were enrolled. Mean age was 26 years. The diagnosis was MFS in 83%. Despite 88% of patients being restricted by their provider, 65% reported competitive sports participation and 93% reported recreational exercise. Participants with an EES greater than the median had significantly better total QOL scores compared to those below the median (78 vs 65, p = 0.03). There were significant positive correlations between current frequency of exercise and psychosocial QOL (slope = 3.9, 95% CI: (1.2, 6.6), p = 0.005), physical QOL (slope = 8.1, 95% CI: (4.1, 12), p < 0.001), and total QOL score (slope = 6.0, 95% CI: (3.1, 9.0), p < 0.001). We found no difference in aortic size or need for surgical intervention between those above and below the median EES, or between those who did and did not participate in competitive sports. Despite exercise restrictions, young HTAD patients are physically active. Increased lifetime exercise and current physical activity levels were associated with improved QOL in HTAD patients.

Paediatric Knee Injuries: A Narrative Review.

The prevalence of paediatric knee injuries is increasing due to higher participation in competitive sports, larger build and more use of imaging in diagnosis. A thorough history of injury (including mechanism and symptoms of pain and instability), together with a comprehensive examination (presence of an effusion, tender areas, range of movement and joint laxity) will dictate the need for radiological investigations. Magnetic Resonance Imaging (MRI) is indicated in most paediatric patients with a history of injury and an acute knee effusion, which indicates damage to an intra-articular structure. Red flags requiring onward referral to a specialist include diagnosed fractures, traumatic knee effusion, instability, or persistent unexplained nocturnal pain or lump. Correct identification and management of injuries will help reduce long-term morbidity. The aim of this review is to provide the reader with an understanding of the management of paediatric knee injuries at primary presentation in the community setting or emergency department.

The influence of parental involvement on academic and sporting achievement: a study of Indonesian students in West Sumatra

This study investigates the impact of parental involvement on students' academic and sporting achievements in Padang, West Sumatra Province, Indonesia. Using a sample of 112 junior high school students, we examined how different forms of parental involvement correlate with students' participation in competitive sports and academic performance. The research employed a quantitative approach, utilizing surveys and statistical analysis including ANOVA. Results indicate that students with parents involved in both academic and sporting activities show significantly higher rates of participation in competitive sports (64.4%) compared to those with uninvolved parents (48.4%). Moreover, students whose parents were involved in their studies reported higher academic achievements and were more likely to receive academic awards. The study also explored the concept of strength-based parenting (SBP) and its potential benefits. Our findings underscore the importance of comprehensive parental involvement in fostering children's success in both academic and athletic domains, providing valuable insights for educators and policymakers in Indonesia and beyond.

Vigorous Exercise in Patients With Congenital Long QT Syndrome: Results of the Prospective, Observational, Multinational LIVE-LQTS Study.

Whether vigorous exercise increases risk of ventricular arrhythmias for individuals diagnosed and treated for congenital long QT syndrome (LQTS) remains unknown. The National Institutes of Health-funded LIVE-LQTS study (Lifestyle and Exercise in the Long QT Syndrome) prospectively enrolled individuals 8 to 60 years of age with phenotypic and/or genotypic LQTS from 37 sites in 5 countries from May 2015 to February 2019. Participants (or parents) answered physical activity and clinical events surveys every 6 months for 3 years with follow-up completed in February 2022. Vigorous exercise was defined as ≥6 metabolic equivalents for >60 hours per year. A blinded Clinical Events Committee adjudicated the composite end point of sudden death, sudden cardiac arrest, ventricular arrhythmia treated by an implantable cardioverter defibrillator, and likely arrhythmic syncope. A National Death Index search ascertained vital status for those with incomplete follow-up. A noninferiority hypothesis (boundary of 1.5) between vigorous exercisers and others was tested with multivariable Cox regression analysis. Among the 1413 participants (13% <18 years of age, 35% 18-25 years of age, 67% female, 25% with implantable cardioverter defibrillators, 90% genotype positive, 49% with LQT1, 91% were treated with beta-blockers, left cardiac sympathetic denervation, and/or implantable cardioverter defibrillator), 52% participated in vigorous exercise (55% of these competitively). Thirty-seven individuals experienced the composite end point (including one sudden cardiac arrest and one sudden death in the nonvigorous group, one sudden cardiac arrest in the vigorous group) with overall event rates at 3 years of 2.6% in the vigorous and 2.7% in the nonvigorous exercise groups. The unadjusted hazard ratio for experience of events for the vigorous group compared with the nonvigorous group was 0.97 (90% CI, 0.57-1.67), with an adjusted hazard ratio of 1.17 (90% CI, 0.67-2.04). The upper 95% one-sided confidence level extended beyond the 1.5 boundary. Neither vigorous or nonvigorous exercise was found to be superior in any group or subgroup. Among individuals diagnosed with phenotypic and/or genotypic LQTS who were risk assessed and treated in experienced centers, LQTS-associated cardiac event rates were low and similar between those exercising vigorously and those not exercising vigorously. Consistent with the low event rate, CIs are wide, and noninferiority was not demonstrated. These data further inform shared decision-making discussions between patient and physician about exercise and competitive sports participation.

Ensemble Algorithm for Risk Prediction of Clinical Failure After Anterior Cruciate Ligament Reconstruction.

Patient-specific risk profiles of clinical failure after anterior cruciate ligament reconstruction (ACLR) are meaningful for preoperative surgical planning and postoperative rehabilitation guidance. To create an ensemble algorithm machine learning (ML) model and ML-based web-based tool that can predict the patient-specific risk of clinical failure after ACLR. Cohort study; Level of evidence, 3. Included were 432 patients (mean age, 26.8 ± 8.4 years; 74.1% male) who underwent anatomic double-bundle ACLR with hamstring tendon autograft between January 2010 and February 2019. The primary outcome was the probability of clinical failure at a minimum 2-year follow-up. The authors included 24 independent variables for feature selection and model development. The data set was split randomly into training sets (75%) and test sets (25%). Models were built using 4 ML algorithms: extreme gradient boosting, random forest, light gradient boosting machine, and adaptive boosting. In addition, a weighted-average voting (WAV) ensemble model was constructed using the ensemble-voting technique to predict clinical failure after ACLR. Concordance (area under the receiver operating characteristic curve [AUC]), calibration, and decision curve analysis were used to evaluate predictive performances of the 5 models. Clinical failure occurred in 73 of the 432 patients (16.9%). The 8 most important predictors for clinical failure were follow-up period, high-grade preoperative knee laxity, time from injury to ACLR, participation in competitive sports, posterior tibial slope, graft diameter, age at surgery, and medial meniscus resection. The WAV ensemble algorithm achieved the best predictive performance based on concordance (AUC, 0.9139), calibration (calibration intercept, -0.1806; calibration slope, 1.2794; Brier score, 0.0888), and decision curve analysis (greatest net benefits) and was used to develop an web-based application to predict a patient's clinical failure risk of ACLR. The WAV ensemble algorithm was able to accurately predict patient-specific risk of clinical failure after ACLR. Clinicians and patients can use the web-based application during preoperative consultation to understand individual prediction outcomes.

Recommendations for competitive sports eligibility: what's new in the 2023 COCIS protocols

The benefit of physical exercise is well established, but, at the same time, it is now well known that an intense sports activity can trigger adverse cardiac events and increase sport-related death. Since 1982, Italy has a State law which obliges athletes to undergo a pre-participation evaluation, based on history, physical examination, ECG and stress test. From its introduction, a significant reduction in cardiac sport-related adverse events has been shown. During the pre-participation screening, some cardiological issues or suspects can arise and the sports medicine doctor should deal with them before releasing the certification for participation in competitive sport. In order to give precious advices to these colleagues and help athletes to securely practice sport, the Italian Society of Sports Cardiology, the Italian Federation of Sports Medicine and the other cardiological scientific societies gathered in the COCIS Committee, periodically produce and publish a booklet named "Cardiological Protocols for Competitive Sports Eligibility". The object of this review is to underline the recent 2023 version innovations when compared to previous editions.

Practical considerations for continuous glucose monitoring in elite athletes with type 1 diabetes mellitus: A narrative review.

Type 1 diabetes mellitus (T1DM) refers to a metabolic condition where a lack of insulin impairs the usual homeostatic mechanisms to control blood glucose levels. Historically, participation in competitive sport has posed a challenge for those with T1DM, where the dynamic changes in blood glucose during exercise can result in dangerously high (hyperglycaemia) or low blood glucoses (hypoglycaemia) levels. Over the last decade, research and technological development has enhanced the methods of monitoring and managing blood glucose levels, thus reducing the chances of experiencing hyper- or hypoglycaemia during exercise. The introduction of continuous glucose monitoring (CGM) systems means that glucose can be monitored conveniently, without the need for frequent fingerpick glucose checks. CGM devices include a fine sensor inserted under the skin, measuring levels of glucose in the interstitial fluid. Readings can be synchronized to a reader or mobile phone app as often as every 1-5min. Use of CGM devices is associated with lower HbA1c and a reduction in hypoglycaemic events, promoting overall health and athletic performance. However, there are limitations to CGM, which must be considered when being used by an athlete with T1DM. These limitations can be addressed by individualized education plans, using protective equipment to prevent sensor dislodgement, as well as further research aiming to: (i) account for disparities between CGM and true blood glucose levels during vigorous exercise; (ii) investigate the effects of temperature and altitude on CGM accuracy, and (iii) explore of the sociological impact of CGM use amongst sportspeople without diabetes on those with T1DM.

Clinical evaluation of ophthalmic findings in active, amateur, adult, competitive male boxers in India.

Background: In the popular fighting sport of boxing, opponents strike each other above the belt line in the face, chest, and belly. The physical parts most exposed are therefore the nose and eyes. In amateur boxing, fights go only three rounds - three minutes for men and one minute for women - with a one-minute break in between. They wear gloves, but the head protection used in the men's game has been removed by AIBA due to the high likelihood of concussion when using head protection. Because chronic ocular changes may take longer than the expected short-term effects, this study included at least 3 years of competitive sports participation. Study design and setting: Institutional-based cross-sectional study. Materials and methods: To evaluate ophthalmic outcomes, 200 eyes of 100 active amateur, adult, and competitive male boxers were studied. Results: Of the 100 boxers, 51 had ophthalmic changes in at least one eye, and 49 had normal eyes. The average age of boxers was 24.98 years. The average duration of boxing training was 7.04 years. Healed eyelid scars, subconjunctival hemorrhages, conjunctival papillae, traumatic mydriasis, posterior synechiae, angulation abnormalities, traumatic cataracts, lens subluxation, increased intraocular pressure, and peripapillary atrophy were observed on the ocular side. None of these could be attributed to boxing. Conclusion: Boxing-related eye injuries are common in India and the most common vision-threatening eye abnormalities include traumatic cataracts, lens subluxation, and angle abnormalities. Surprisingly, no macular lesions were found on physical examination and OCT. Additional studies with a larger number of boxers will be needed to evaluate and prevent clinical symptoms. All boxers should have a complete eye exam regularly. Abbreviations: AIBA = Association Internationale de Boxe Amateur, OCT = Optical Coherence Tomography.

Adolescent Predictors of Firearm Suicide Over Four Decades of Life in U.S. Men

There are meager individual-level data on long-term predictors of firearm suicide. This was an analysis of males (N=189,558) in the Project Talent cohort, a national probability sample of high school schools in 1960 when students completed a baseline Project Talent self-report inventory. Mortality follow-up was contingent on survival until 1979, the onset of the National Death Index when the cohort had a mean age of 35.7 years. Mortality follow-up continued until death or age 75 years, reached by all surviving members by 2018. Analyses were conducted in 2022, with the main outcome being firearm suicide deaths (n=479). Factor analyses of Project Talent items yielded three key factors: (1) interests in firearm-related professions (i.e., military service, police force), (2) interests in hunting or fishing and knowledge of long guns, and (3) stereotypic masculinity. Survival analyses showed that long-term risk for firearm suicide was associated with 1-SD increases in firearm-related vocational interests in adolescence (adjusted hazard ratio [95% CI]=1.23 [1.09, 1.40]) and masculinity (adjusted hazard ratio [95% CI]=1.15 [1.04, 1.28]). Decreased long-term firearm suicide risk was associated with increased hunting interests and knowledge of long guns in adolescence (adjusted hazard ratio [95% CI]=0.86 [0.77, 0.96]) and competitive sports participation, an exploratory variable (adjusted hazard ratio [95% CI]=0.89 [0.80, 0.99]). Prevention efforts are needed to lower long-term firearm suicide risk among adolescent males with high stereotypic masculinity and those interested in military or police service. Potential protective effects of competitive sports participation and socialization to long guns through hunting require further study.

Abstract 15404: Exercise and Sports Participation is Associated With Improved Quality of Life in Young Patients With Heritable Thoracic Aortic Disease

Introduction: Traditionally, patients with heritable thoracic aortic disease (HTAD) have been restricted from competitive sports due to concerns over acute aortic dissection. Patients with HTAD also exhibit lower quality of life (QOL) and physical fitness than general populations. Murine data suggests exercise improves aortic health and does not contribute to aortic enlargement. Hypothesis: Exercise and competitive sports participation will be associated with improved QOL in HTAD patients. Aims: Investigate the effect of lifetime exercise ‘dose’ and competitive sports participation on QOL in patients aged 15-35 with syndromic HTAD [Marfan syndrome (MS), Loeys-Dietz syndrome (LDS), vascular Ehlers-Danlos syndrome (vEDS)] and non-syndromic HTAD. Methods: This cross-sectional study employed a questionnaire to assess lifetime exercise exposure and utilized the PedsQL QOL Inventory. We developed an Exercise Score (ES) to quantify lifetime exercise exposure based on questionnaire results (3 points for competitive sports season, 1 point for recreational sport season. Questionnaires were completed via telephone interview with complimentary medical chart review. Results: Of the forty patients enrolled, the mean age was 26 years. The diagnosis was MS in 82.5%. Despite 87.5% of patients being restricted by their cardiologist, 65% reported competitive sports participation and 92.5% reported some lifetime recreational exercise. The median ES for our population was 19. Participants with an ES greater than the median had a significantly better total QOL score compared to participants with an ES below the median (78 vs 65, p=0.03). There was no difference in aortic size or need for surgical intervention between those above and below the median ES. This also held true for those who did and did not participate in competitive sports. There was a strong positive correlation between the amount of current exercise (days-per-week) and total QOL score (corr=0.55, p&lt;0.001). Conclusions: Increased lifetime exercise exposure and current physical activity levels were associated with improved QOL in young adults with HTAD. There did not appear to be a detrimental effect of exercise on aortic size or need for surgical intervention.

Abstract 14706: Outcomes of Sports Participation for Black Athletes With Implantable Cardioverter-Defibrillators: Data From the ICD Sports Registry

Introduction: The ICD Sports Registry demonstrated that many athletes with ICDs can participate in competitive sports without death, failure to defibrillate, or physical injury. However, sudden cardiac arrest is more prevalent and has worse outcomes in Black compared to White individuals in the general population and among athletes. Outcomes of sports participation for Black athletes with ICDs have not been described. Aim: To describe the risk of arrhythmia and efficacy of ICDs in Black athletes. Methods: This is a post-hoc subgroup analysis of the ICD Sports Registry, which enrolled athletes with ICDs age 10 to 60, participating in organized, competitive sports, and followed them prospectively for four years. The endpoints and methods are reported previously. Results: Among the 440 athletes, 15 were Black and 410 white. Among the Black athletes, hypertrophic cardiomyopathy was the most common diagnosis (40%) and 87% were implanted for secondary prevention or syncope (vs 69% in White athletes). Most common sports were basketball (8), softball (4), and running (3), with 7 Black athletes competing on varsity/junior varsity/traveling teams. Among the Black athletes, there were no appropriate shocks during sports, among white athletes, 7% received an appropriate shock during sports. Among Black athletes, there was one appropriate shock event for ventricular tachycardia (7%), a VT storm in an athlete with idiopathic VF, non-sports-related. Among white athletes, 10% received appropriate shocks during non-sports activities. Two Black athletes (13%) received an inappropriate shock, one competition-related (sinus tachycardia) and the other for T wave oversensing at rest, vs 12% of white athletes. There were no sports-related deaths, arrests, or arrhythmia-related injuries in either group. Conclusions: Black athletes represented a small subset of the ICD Sports Registry. Reasons for this are unknown, but may include disparities in ICD implantation and/or in research recruitment/ participation. These Black athletes experienced both appropriate and inappropriate shocks as did white athletes. These data do not suggest a signal for harm for competitive sports participation for Black athletes with ICDs but larger studies are needed.

Body composition in male lifelong trained strength, sprint and endurance athletes and healthy age-matched controls.

Aging involves many physiological processes that lead to decreases in muscle mass and increases in fat mass. While regular exercise can counteract such negative body composition outcomes, masters athletes maintain high levels of exercise throughout their lives. This provides a unique model to assess the impact of inherent aging. The present study compared lean mass and fat mass in young and masters athletes from different sports to age-matched non-athletic individuals. Participants included young (20-39 years, n = 109) and older (70-89 years, n = 147) competitive male athletes, and 147 healthy age-matched controls (young = 53, older = 94 males). Athletes were separated into strength (e.g., weightlifters, powerlifters), sprint (e.g., sprint runners, jumpers) and endurance (e.g., long-distance runners, cross-country skiers) athletic disciplines. Body composition was assessed by dual-energy x-ray absorptiometry (DXA). Upper and lower limb lean mass was combined for appendicular lean mass as well as appendicular lean mass index (ALMI; kg/m2). Individuals' scores were assessed against established cut-offs for low muscle mass, obesity, and sarcopenic obesity to determine prevalence in each group. ALMI was greater in young strength (0.81-2.36 kg/m2, ∼15% and 1.24-2.74 kg/m2, ∼19%) and sprint (95% CI = 0.51-1.61 kg/m2, ∼11% and 0.96-1.97 kg/m2, ∼15%) athletes than in endurance and controls, respectively (all P < 0.001). In masters athletes, only strength athletes had greater ALMI than endurance athletes, but both older strength and sprint athletes had greater ALMI than older controls (0.42-1.27 kg/m2, ∼9% and 0.73-1.67 kg/m2, ∼13%, respectively, both P < 0.001). Fat mass was significantly lower in sprint and endurance athletes compared to strength athletes and controls in both age-groups. Sarcopenic obesity was identified in one young (2%) and eighteen (19%) older controls, while only two older endurance athletes (3%) and one older strength athlete (2%) were identified. Lifelong competitive sport participation leads to lower prevalence of sarcopenic obesity than a recreationally active lifestyle. This is achieved in strength athletes by emphasizing muscle mass, while sprint and endurance athletes demonstrate low fat mass levels. However, all older athlete groups showed higher fat mass than the young groups, suggesting that exercise alone may not be sufficient to manage fat mass.

Call It an "Evolution": Promoting Student-Athlete Well-Being During the Transition From Collegiate Sport.

After highly publicized stories of student-athletes' struggles with mental health, the spotlight on mental health and well-being in this special issue coincides with a broader growing concern for the long-term impact of competitive sport participation on student-athlete health and wellness. The end of a competitive sport career represents a potentially vulnerable life transition. As demonstrated in the literature, the unique aspects of elite sport culture shape student-athletes' perceptions of their identity, health, and health behaviors, which have implications for how student-athletes navigate their health and well-being as they transition away from the embedded health care structure inherent to elite sport. Given evidence indicating that student-athletes may face mental and physical health concerns after retirement from sports, targeted transitional strategies are needed to provide patient-centered care in this population. In this article, we briefly summarize current understanding of sport transition and highlight some key findings from studies conducted by the contributing authors' research groups exploring the impact of sport career transitions on student-athlete well-being. We also reflect on limitations of the existing research and transition models and, in turn, propose potential directions for adopting a nuanced and multidimensional framework to explore interconnected transition domains. We conclude by offering recommendations for sports medicine professionals to consider in future research, programming, and policies to promote student-athletes' holistic well-being through this critical transition.

Competitive Sports Participation is Associated with Decreased Risk of Obesity in Children with Bicuspid Aortic Valve.

Individuals with bicuspid aortic valve (BAV) have historically been advised to avoid contact sports and isometric exercise for risk of increasing aortic dilation and valve disease. There is mounting evidence that current sports participation guidelines qualify children for a high rate of sports exclusion, and that this population is at increased risk of obesity. The primary aim of this study was to evaluate relationship between sports participation and aortic dilation in children with bicuspid aortic valve and secondarily the relationship between competitive sports participation and obesity. We performed a review of children between the ages of 8 and 17years with isolated BAV followed at Oregon Health & Science University. We excluded those with other congenital heart diseases, genetic conditions, prior cardiac intervention, and inability to ambulate independently. Parents completed a phone survey detailing their child's level of daily activity and participation in competitive sports. Demographic information and most recent echo findings were collected from the electronic medical record. We found no difference between the aortic diameters of athletes vs non-athletes. We also found that sports participation and daily activity were both associated with a decreased likelihood of obesity (OR 0.24, 95% CI 0.078-0.73 and OR 0.24, 95% CI 0.081-0.71 respectively). In summary, in our sample population, competitive sports participation was associated with a decreased risk of obesity. Competitive sports participation does not appear to be associated with an increased risk of aortic dilation in our population.
