High rates of respiratory illnesses upon arrival: lessons from Team USA at the Santiago 2023 Pan American and Parapan American Games.

OBJECTIVE: To describe the incidence and characteristics of injuries and illnesses among Team USA athletes competing at the Santiago 2023 Pan American Games (PAG) and Parapan American Games (PPAG), with a particular focus on the incidence of respiratory illnesses and on injuries for sports new to the Olympic and Paralympic programmes. METHODS: Illnesses and injuries occurring among the 870 Team USA athletes competing in the Santiago 2023 PAG or PPAG were documented within Team USA's Injury and Illness Surveillance system. Illness and injury incidence per 1000 athlete-days (ADs) and incidence ratios (IR) were calculated, both with 95% CIs. RESULTS: Illness (IR 2.5, 95% CI 1.6, 3.9) and injury (IR 1.8, 95% CI 1.3, 2.5) rates were greater during PPAG compared with PAG. Illness rates were higher in the pre-opening ceremony period compared with the competition period for both PAG (IR 2.7, 95% CI 1.1, 5.9) and PPAG (IR 1.9, 95% CI 0.9, 3.8). Respiratory illness was the most common illness with 3.2% and 8.9% of all Team USA athletes reporting a respiratory illness during the PAG and PPAG, respectively. Sports that are relatively new to the Olympic/Paralympic programmes exhibited the highest injury rates during the Games: breaking (250.0 (91.7, 544.2) per 1000 ADs), Para taekwondo (93.8 (19.3, 274.0) per 1000 ADs) and surfing (88.9 (24.2, 227.6) per 1000 ADs). CONCLUSION: Respiratory illness rates were the most common type of illness during both PAG and PPAG and were more likely to occur prior to competition starting. Our data have identified high injury risk populations (breaking, surfing, Para taekwondo) and timing (pre-opening ceremony period) for further risk factor analysis.

Development and implementation of an injury and illness surveillance system for team USA.

BACKGROUND: The purpose of this report is to provide insight and details regarding the development and implementation of an injury and illness surveillance (IIS) system for the United States Olympic and Paralympic Committee (USOPC). METHODS: The development and deployment of the IIS employed a multiphase approach. First, researchers determined variables to include in the IIS using the recommendations from the 2020 IOC consensus statement for reporting sport epidemiological data. Second, the hosting and deployment platforms were comprehensively evaluated for their suitability, ease of use, flexibility, and backend data structure (for both capture and aggregation). Third, focus groups consisting of the Sports Medicine department leadership and clinicians piloted the IIS system and revisions were made based on their feedback. Pilot testing of the IIS and follow-up focus groups were then conducted among all departmental clinicians to solicit additional feedback and drive further revisions. Finally, the IIS system was piloted among providers working during the 2023 Pan American and Parapan American Games to refine the system for future Games. After reviewing all potential software platform options (electronic medical record [EMR] system, athlete management systems, secure data collection platforms), Qualtrics (Qualtrics, Provo, UT, USA) was selected to host the IIS system. This choice was made due to the inability of the EMR and athlete-management systems to make frequent updates, modify existing questions, and provide the necessary form logic for the variety of scenarios in which the IIS system would be deployed. Feedback from the department's leadership and clinicians resulted in a number of changes, most notably being the ability to enter multiple diagnoses for a single injury event. Additionally, clinician feedback resulted in the creation of additional diagnostic codes not currently present in the OSIICS v14.0 diagnostic coding system, adding "non-sport" as an additional variable for injury setting, and developing a system for reporting return-to-sport date for time-loss injuries. DISCUSSION: A multi-stage process of extensive planning, stakeholder feedback, and ongoing updates is required in order to successfully develop and implement an IIS system within a National Olympic and Paralynpic Committee. This process can be used to inform the development and implementation of IIS systems in other sporting organizations.

Factors Influencing Athletic Training Services in California Secondary Schools: A Five- Year Update.

CONTEXT: California is the only state that does not regulate the athletic training profession, allowing unqualified personnel to be hired and call themselves athletic trainers. The benefits of employing a certified athletic trainer in the secondary school setting are numerous but efforts to push regulation legislation continue to fail in California. OBJECTIVE: To describe the availability of certified athletic trainers in California secondary schools and explore factors influencing athletic trainer employment. DESIGN: Cross-Sectional Study. SETTING: Online survey. PATIENTS OR OTHER PARTICIPANTS: Participants from 1538 California Secondary Schools. MAIN OUTCOME MEASURES: Officials from member schools completed the 2022-2023 California Interscholastic Federation Participation Census. Participants provided information specific to enrollment, sport participation, access to AEDs, and whether the school had athletic trainers on staff. The athletic trainer's certification status was independently verified. Enrollment data specific to ethnicity, race, and percentage of students eligible for free meals was obtained through the California Department of Education Statistics. RESULTS: More than half (51.6%) of California secondary schools did not employ a certified athletic trainer and 8.3% employed unqualified personnel as athletic trainers. Nearly half (43%) of student athlete participants were enrolled at schools with no certified athletic trainer. Schools that employed certified athletic trainers had a lower proportion of students eligible to receive free and reduced-price meals. The average percentage of Hispanic or Latino students was greater in schools with no certified athletic trainer and schools that employed unqualified personnel as athletic trainers than schools that employed certified athletic trainers. CONCLUSIONS: Data indicates that in a five-year period, access to athletic training services in California secondary schools has not improved. There are large gaps in access to athletic training services and there are clear socioeconomic and racial and ethnic disparities. Efforts to educate stakeholders on the importance of athletic training regulation in California should continue.

Injury risk factors related to sport specialization in high school basketball: a prospective study.

CONTEXT: Research that has examined the association between specialization and injury in basketball has been limited to cross-sectional or retrospective studies. OBJECTIVE: To determine whether specialization is a risk factor for injury among high school basketball athletes. DESIGN: Prospective cohort study. SETTING: Basketball players from 12 high schools participating in the National Athletic Treatment, Injury, and Outcomes Network Surveillance Program (NATION-SP) were recruited prior to the 2022-2023 interscholastic basketball season. PATIENTS OR OTHER PARTICIPANTS: 130 athletes (mean age (SD) = 15.6 (1.3); girls' basketball: n=68 (52.3%)). MAIN OUTCOME MEASURES: Participants completed a questionnaire prior to the start of their school basketball season that had questions regarding participation in various specialized sport behaviors. During the basketball season, the school's athletic trainer reported all athletic exposures (AEs) and injuries (regardless of time loss) for participating athletes into NATION-SP. Injury incidence (IR) and incidence rate ratios (IRR) with 95% confidence intervals [95%CI] were calculated for the specialized sport behaviors previously described. RESULTS: There was no difference in injury risk between highly specialized and low specialized athletes (IRR [95%CI]: 1.9 [0.9, 3.7]). Players who participated in basketball year-round were twice as likely to sustain an injury compared to those who did not play year-round (IRR [95%CI]: 2.1 [1.1, 3.6]). Similarly, players who reported participating in basketball skills camps were at increased risk of injury compared to athletes who did not participate in basketball skill camps (IRR [95%CI]: 2.5 [1.2, 5.7]). CONCLUSION: Injury risk related to sport specialization in basketball may be specific to certain behaviors such as year-round play and participation in skills camps. Validated measures of comprehensive sport activity are needed to better measure specialization in youth sports to better determine injury risk related to sport specialization and develop injury prevention programs for basketball athletes.

Incidence of staff injury and illness at the Tokyo 2020 and Beijing 2022 Olympic and Paralympic Games.

Objective: To report epidemiological data regarding injury and illness among the Team USA staff during the Tokyo 2020 Summer Olympic and Paralympic Games and Beijing 2022 Winter Olympic and Paralympic Games. Methods: A retrospective review of all Team USA staff (total staff, N=1703 (62.5% female); total staff days (SD)=34 489) medical encounters during the Tokyo 2020 Games and Beijing 2022 Games was conducted. Details related to injury and illness were evaluated. Incidence with 95% CI per 1000 staff days were calculated. Results: A total of 32 illnesses (incidence [95% CI] 0.9 [0.6, 1.2]) and 23 injuries (incidence 0.7 [0.4, 0.9]) were sustained by the Team USA delegation staff members during the Tokyo 2020 Games and Beijing 2022 Games. Female staff reported more illnesses (illnesses proportion (IP) 2.9%; incidence 1.4 [0.8, 2.0]), while male staff incurred more injuries (IP 1.8%; incidence 0.9 [0.5, 1.3]). When stratified by physiological system, dermatological and infectious were the most common systems involved with illness (IP 0.5%; incidence 0.2 [0.1, 0.4]). Injuries to the upper limb were most common (IP 0.3%; incidence 0.3 [0.1, 0.5]). Conclusion: Injury and illness rates among the Team USA staff during the Tokyo 2020 Games and Beijing 2022 Games were low, but notable. Knowledge of injury and illness risks contributes to staffing decisions and prevention strategies for staff supporting athletes during competition.

Addressing Circadian Disruptions in Visually Impaired Paralympic Athletes.

PURPOSE: Transmeridian travel is common for elite athletes participating in competitions and training. However, this travel can lead to circadian misalignment wherein the internal biological clock becomes desynchronized with the light-dark cycle of the new environment, resulting in performance decrement and potential negative health consequences. Existing literature extensively discusses recommendations for managing jet lag, predominantly emphasizing light-based interventions to synchronize the internal clock with the anticipated time at the destination. Nevertheless, visually impaired (VI) athletes may lack photoreceptiveness, diminishing or nullifying the effectiveness of this therapy. Consequently, this invited commentary explores alternative strategies for addressing jet lag in VI athletes. CONCLUSIONS: VI athletes with light perception but reduced visual acuity or visual fields may still benefit from light interventions in managing jet lag. However, VI athletes lacking a conscious perception of light should rely on gradual shifts in behavioral factors, such as meal timing and exercise, to facilitate the entrainment of circadian rhythms to the destination time. Furthermore, interventions like melatonin supplementation may prove useful during and after travel. In addition, it is recommended that athlete guides adopt phase-forward or phase-back approaches to synchronize with the athlete, aiding in jet-lag management and optimizing performance.

Sleep Quality in Team USA Olympic and Paralympic Athletes.

Adequate sleep is crucial for elite athletes' recovery, performance readiness, and immune response. Establishing reference ranges for elite athletes enables appropriate contextualization for designing and targeting sleep interventions. PURPOSE: To establish sleep-quality reference ranges for Olympic and Paralympic cohorts using the Pittsburgh Sleep Quality Index (PSQI) and explore differences based on sex and sport types. METHODS: Team USA athletes (men = 805, women = 798) completed the PSQI as part of a health-history questionnaire. Descriptive statistics were used to create reference ranges and linear models, and χ2 test of independence determined differences in PSQI global and component scores between sex, games, season, and participation. RESULTS: Six hundred thirty-two (39.43%) athletes reported poor sleep (PSQIGlobal ≥ 5). Men displayed later bedtimes (P = .006), better global PSQI scores, shorter sleep latency, less sleep disturbance, and less use of sleep medication than women (all P < .001). Winter Games participants had later bedtime (P = .036) and sleep offset time (P = .028) compared with Summer Games athletes. Team-sport athletes woke earlier than individual-sport athletes (P < .001). Individual-sport athletes were more likely to have low (P = .005) and mild (P = .045) risk for reduced sleep duration than team-sport athletes. CONCLUSION: These data provide PSQI-specific reference ranges to identify groups at greatest risk for poor sleep, who may benefit most from targeted sleep interventions.

Incidence of injury and illness among paediatric Team USA athletes competing in the 2020 Tokyo and 2022 Beijing Olympic and Paralympic Games.

Objective: To describe the incidence of injuries and illnesses among paediatric Team USA athletes competing in the Tokyo 2020 Olympic and Paralympic Games, and the 2022 Beijing Olympic and Paralympic Games. Methods: An electronic medical record system documented all injuries and illnesses that occurred while competing in the four Games periods. Incidence (IR) with 95% CI per 1000 athlete days were calculated for both injuries and illnesses. Incidence rate ratios (IRR) were calculated to compare injury and illness rates based on age (paediatric vs non-paediatric) sex, Games period and sport type. Results: Two hundred paediatric athletes (age range, 15-21 years) competed across the four Games periods, representing 16.1% of all Team USA athletes. The overall injury IR (95% CI) was 13.4 (9.8 to 18.1), and the overall illness IR was 5.5 (3.3 to 8.7). There were no differences in incidence between paediatric and non-paediatric athletes for either injury (IRR (95% CI): 0.9 (0.6 to 1.2)) or illness (IRR (95% CI): 0.9 (0.5 to 1.5)). Female paediatric athletes were more likely to sustain an injury compared with male paediatric athletes (IRR (95% CI): 2.4 (1.1 to 5.3)). The most common mechanism of injury was gradual onset (IR, 4.3 (2.3 to 7.2)), and injuries most commonly occurred during practices (IR, 7.0 (4.5 to 10.5)). Conclusion: Paediatric athletes account for a substantial proportion of Team USA athletes. It is essential that paediatric sports medicine experts are included in the medical team given that paediatric Team USA athletes are just as likely as their adult teammates to sustain an injury or illness.

Higher Levels of Income and Education are Associated with More Specialized Sport Participation Behaviors: Results from a Representative Sample of Youth Sport Parents from the United States.

Background: While previous studies have examined the impact of family socioeconomic characteristics on a child's sport specialization behaviors, this research has been limited to affluent communities with limited sociodemographic diversity. Hypothesis/Purpose: The purpose of this study was to examine associations of parent income and education with child sport specialization behaviors among a nationally representative sample of youth sport parents in the United States. Study Design: Cross-sectional. Methods: Parents of youth athletes in the United States (n=236, age: 39.2±8.1 years, 57.2% female) were recruited to complete an online questionnaire by Qualtrics Online Samples (Qualtrics, Provo, UT) using a combination of actively managed, double-opt-in market research panels. The questionnaire used for this study consisted of: 1) parent demographics (including parent age, race/ethnicity, biological sex, gender identity, household income, and educational status), and 2) child sport participation characteristics and sport specialization behaviors. Results: Parents who reported an annual household income of $75,001 or more were more likely than parents making less than $75,000 to report that their child participated on an organized club team (OR [95%CI]: 1.94 [1.15-3.27]), participated on multiple organized teams at the same time (OR [95%CI]: 1.85 [1.10-3.11]), or specialized in a single sport (OR [95%CI]: 2.45 [1.45-4.14]). Parents who reported receiving a Bachelor's degree or higher were more likely than parents who did not to report that their child participated on an organized club team (OR [95%CI]: 3.04 [1.78-5.18]), participated on multiple organized teams at the same time (OR [95%CI]: 2.42 [1.43-4.10]), or specialized in a single sport (OR [95%CI]: 1.94 [1.15-3.26]). Conclusions: Thes results suggest that in the modern youth sport culture, family resources may serve as a major determining factor in the type of experiences available for a youth athlete. Level of Evidence: III.

The Impact of the Social Determinants of Health on Athletic Trainer Availability in Indiana Secondary Schools.

CONTEXT: The Social Determinants of Health (SDOH) are circumstances individuals are born, work, and live, that influence health outcomes. Previous research has examined one determinant of economic stability and found disparities in socioeconomic status and athletic trainer availability (AT availability). OBJECTIVE: Examine SDOH characteristics of Indiana secondary schools and AT availability. DESIGN: Cross-sectional study. SETTING: Database secondary analysis. PARTICIPANTS: 426 secondary schools. MAIN OUTCOME MEASURES: All data was collected from publically available databases. The independent variable was AT availability, schools were classified as having a full-time AT (full-time AT), a part-time AT only (part-time AT), or no AT (no AT). The SDOH variables were gathered for each school (school and county-level). Data were summarized using measures of central tendencies, one-way ANOVAs, and Kruskal-Wallis tests. RESULTS: School enrollment was larger in schools with greater AT availability (p<.001). The proportion of non-white students was greater in schools with more AT availability (p=0.002). There was greater AT availability in counties with higher graduation rates (p=0.03). Post-hoc comparisons revealed significant differences in graduation rate between part-time AT and no AT schools (p=0.04). Schools with less AT availability were located in counties with a slightly higher percentage of the population uninsured (p=0.02). Schools with greater AT availability were located in counties with a higher ratio of population to primary care physicians (p=0.03). Schools with less AT availability were located in counties with higher population experiencing severe housing problems (p=0.02). There were no significant differences in AT availability based on the three social and community context variables (p>0.05). CONCLUSIONS: We found differences in AT availability and a different SDOH characteristics at the secondary school-level. There was less AT availability where high school graduation rates and population of primary care providers are lower. Strategies should be implemented to improve access to athletic health care in under-resourced communities.

Motivation and Behaviors Related to Sport Specialization in College Baseball Players.

CONTEXT: Early sport specialization is a growing concern among youth sports athletes, particularly in baseball. Motivation to participate in sports is an important factor in determining which sports youth athletes participate in and why. OBJECTIVE: The purpose of this study was to qualitatively investigate youth sport participation behaviors and motivations of college baseball players. DESIGN: Qualitative Study. SETTING: Online Teleconference. PATIENTS OR OTHER PARTICIPANTS: We conducted 25 semi-structured interviews with college baseball athletes who were classified as either high-level (n=8), moderate-level (n=9), or low-level specialists (n=8) prior to college. DATA COLLECTION AND ANALYSIS: Participants completed an individual semi-structured interview to develop an understanding of the participants' youth and high school sports experiences and associated motivations to participate in those experiences. A framework analysis approach was used to analyze transcript data to identify themes among the three specialization groups. RESULTS: From our interview analysis, six overall themes emerged among the groups: (1) Motivation, (2) Stress, (3) Quitting, (4) Barriers, (5) Facilitators of Success, and (6) Future Directions. Moderate and high-level specialists described higher levels of passion, participating in deliberate practice, higher levels of performance-related stress, and a desire to quit sports more than low-level specialists. None of the groups described parents as an overbearing external motivator to participate in sports at an early age. CONCLUSIONS: Participants who were classified as low-, moderate-, and high-level specialists described different experiences related to their motivation, stress levels, desire to quit, barriers to participating in baseball, facilitators of success, and their overall future career goals after completing baseball. This information may be useful for parents, coaches, and health care professionals to better communicate the benefits and risks associated with sport specialization to youth athletes. Future research is needed to determine if differences in motivation levels exist in younger populations.

Athletic Trainers' Psychosocial Experiences During the COVID-19 Pandemic: A Qualitative Research Study.

CONTEXT: Despite the many challenges posed by the COVID-19 pandemic, athletic programs have sought ways to persevere and deliver sport programming. This process has strained the psychosocial health of all sport stakeholders but especially those entrusted with promoting the health of participants and enforcing safety protocols. Athletic trainers (ATs) have been a major influence in striving to achieve these goals by expanding their typical roles to lead in promoting the safe delivery of sport programs. OBJECTIVE: To examine the psychosocial lived experiences of ATs as they practiced during the COVID-19 pandemic. DESIGN: Qualitative study. SETTING: National Collegiate Athletic Association Divisions I, II, and III. PATIENTS OR OTHER PARTICIPANTS: A total of 27 ATs practicing at the collegiate level (Divisions I, II, and III) who were actively involved in planning and implementing return-to-sport protocols during the COVID-19 pandemic. DATA COLLECTION AND ANALYSIS: Semi-structured interviews were conducted via Zoom. Inductive conventional content analysis identified emerging themes that characterized participants' narratives. Three members of the research team were involved in the analysis process and used field notes, continuous member checking, peer review, and multiple-researcher triangulation to establish data credibility and confirmability. RESULTS: Three higher-order themes related to ATs' psychosocial lived experiences emerged: (1) internalized experience, (2) interpersonal interactions, and (3) AT identity. Several subthemes were also identified to further organize elements that characterized or differentiated participants' lived experiences. CONCLUSIONS: Athletic trainers encountered significant challenges in maintaining their psychosocial health during the pandemic as they strived to assist others in this regard. Providing effective psychological and social support resources and strategies for ATs may not only allow them to better support themselves but may also enhance their ability to deliver professional services and promote psychosocial health among their athletes and other stakeholders in their respective sport systems in the future.

Pediatric Health Care Provider Awareness, Perceptions, and Utility of Sport Specialization Recommendations.

CONTEXT: Sport specialization, or focused participation in a single sport, is associated with an increased rate of overuse injury and burnout. Medical associations and sport organizations have published recommendations for sport specialization aimed at reducing its negative consequences. Health care providers (HCPs) are often identified as individuals who can educate athletes and parents about these important recommendations. OBJECTIVE: To compare knowledge, perceptions, awareness, confidence in knowledge, and use of sport specialization recommendations among HCPs who work with pediatric athletes. DESIGN: Cross-sectional study. SETTING: An online web-based survey was developed to assess HCPs' knowledge, perceptions, awareness, confidence in knowledge, and clinical use of sport specialization recommendations. PATIENTS OR OTHER PARTICIPANTS: Participants were recruited from the research survey services of 4 professional organizations. MAIN OUTCOME MEASURE(S): Dependent variables were responses for awareness, perceptions, confidence in knowledge, use, and barriers sections of the survey. Data were analyzed with descriptive statistics; comparisons among HCPs were made through χ2 and Kruskal-Wallis tests. RESULTS: The survey was completed by 770 HCPs (completion rate = 95.1%). Respondents lacked awareness specific to recommendations surrounding the maximum number of sport participation months per year (39.5%), maximum hours per week (40.7%), and maximum number of teams on which youth athletes should participate concurrently (43.9%). Physicians were the most aware of medical organization recommendations generally (48%-68.8%) and confident in their knowledge (41.5%-75.1%). All HCPs were less aware and confident in their knowledge of sport organization recommendations, with no differences among HCPs. Physicians did not perceive many barriers to the use of the recommendations, whereas athletic trainers felt that patient (39.9%) and parent (45.3%) behaviors were the greatest barriers to usage. CONCLUSIONS: Awareness, perceptions, and use of sport specialization recommendations varied by discipline, but most respondents believed they were associated with a decreased risk of injury. Future researchers should focus on improved education and implementation of recommendations across all roles.

Differences in Access to Athletic Trainers in Public Secondary Schools Based on Socioeconomic Status.

CONTEXT: Significant health care disparities exist in the United States based on socioeconomic status (SES), but the role SES has in secondary school athletes' access to athletic training services has not been examined on a national scale. OBJECTIVE: To identify differences in access to athletic training services in public secondary schools based on school SES. DESIGN: Cross-sectional study. SETTING: Database secondary analysis. PATIENTS OR OTHER PARTICIPANTS: Data for 3482 public high schools. MAIN OUTCOME MEASURE(S): Data were gathered from the Athletic Training Locations and Services (ATLAS) database, US Census Bureau, and National Center for Education Statistics. We included schools from 5 states with the highest, middle, and lowest poverty percentages (15 states total) and collected county median household income, percentage of students eligible for free or reduced-price lunch, race and ethnicity demographics, and access to athletic training services (full-time athletic trainer [AT], part-time AT only, no AT) for each school. Data were summarized in means, SDs, medians, interquartile ranges (IQRs), frequencies and proportions, 1-way analyses of variance, and Kruskal-Wallis tests. RESULTS: Differences were present in school SES between schools with full-time, part-time-only, and no athletic training services. Schools with greater access to athletic training services had fewer students eligible for free or reduced-price lunch (full time: 41.1% ± 22.3%, part time only: 45.8% ± 24.3%, no AT: 52.9% ± 24.9; P < .001). Similarly, county median household income was higher in schools with increased access to athletic training services (full time median [IQR]: $56 026 [$49 085-$64 557], part time only: $52 719 [$45 355-$62 105], and no AT: $49 584 [$41 094-$57 688]; P < .001). CONCLUSIONS: Disparities in SES were seen in access to athletic training services among a national sample of public secondary schools. Access to ATs positively influences student-athletes' health care across several measures. Pilot programs or government funds have been used previously to fund athletic training services and should be considered to ensure equitable access, regardless of school SES.

Early Sport Specialization and Long-term Throwing Arm Health in College Baseball Players.

BACKGROUND: Early sport specialization is associated with increased risk of overuse injuries in several sports, including baseball. However, limited evidence exists evaluating how early sport specialization affects patient-reported outcome measures as they age. The purpose of this study was to determine differences in Kerlan-Jobe Orthopedic Clinic (KJOC) Shoulder and Elbow Scores among collegiate baseball players based on the grade when a participant first reported high specialization behaviors. HYPOTHESIS: Baseball players who were highly specialized at a younger age will have worse throwing arm health while participating in college. STUDY DESIGN: Cross-sectional study. LEVEL OF EVIDENCE: Level 3. METHODS: A total of 752 college baseball players was contacted through their institution's athletic trainer. We measured baseball specialization and KJOC scores using the validated Baseball and Sport Experience survey. Data were summarized using means and SDs, medians and interquartile ranges (IQRs), and frequencies and percentages. A Kruskal-Wallis test was used to determine differences in mean KJOC scale scores based on the earliest time the participant reported high-level specialization. RESULTS: A total of 294 baseball players completed the survey (response rate: 39.1%). Of the 294 participants, 280 completed the KJOC scale questions to generate a total KJOC score (median: 90.5; IQR: 76.6-97.2). No significant differences in KJOC total scores (P = 0.78) existed based on the grade period in which the athlete was first highly specialized. CONCLUSION: Early baseball specialization as a youth baseball player may not impact throwing arm health in college baseball athletes. CLINICAL RELEVANCE: Early specialization has been linked to increased risk for overuse injuries in certain sports, but may not lead to poorer throwing arm health in college baseball players. Sports medicine clinicians and researchers may use this information to educate various stakeholders about the benefits and risks associated with early sport specialization.

Epidemiology of Overuse Injuries in US Secondary School Athletics From 2014-2015 to 2018-2019 Using the National Athletic Treatment, Injury and Outcomes Network Surveillance Program.

CONTEXT: With 8 million annual US high school student-athletes, the epidemiology of sport-related injuries has garnered significant interest. The most recent studies examining overuse injury rates in high school sports were based on data from 2012 to 2013 and, therefore, may not reflect current overuse injury rates in high school sports. OBJECTIVE: To (1) determine overuse time-loss (TL) and non-time-loss (NTL) injury rates among high school student-athletes using National Athletic Treatment, Injury and Outcomes Network Surveillance Program (NATION-SP) data collected from 2014-2015 to 2018-2019 and (2) compare overuse injury rates based on student-athlete sex defined by whether it was a boys' sport or a girls' sport, the sport itself, and the injury location. DESIGN: Descriptive epidemiology study. SETTING: Online injury surveillance from 211 high schools (345 individual years of high school data). PATIENTS OR OTHER PARTICIPANTS: Athletes who participated in secondary school-sponsored boys' or girls' sports. MAIN OUTCOME MEASURE(S): Boys' and girls' overuse injury data from the NATION-SP during the 2014-2015 to 2018-2019 school years were analyzed. Overuse injuries were identified using a combination of the reported injury mechanism and diagnosis. Time-loss injuries resulted in restriction from participation beyond the day of injury; NTL injuries did not result in restriction from participation beyond the day of injury or involved no lost time due to the injury. Injury counts, rates, and rate ratios (IRRs) were reported with 95% CIs. RESULTS: The total overuse injury rate was 5.3/10 000 athlete-exposures (AEs; 95% CI = 5.1, 5.7), the NTL overuse injury rate was 3.4/10 000 AEs (95% CI = 3.1, 3.6), and the TL overuse injury rate was 2.0/10 000 AEs (95% CI = 1.8, 2.2). The overuse injury rate was greater in girls' sports compared with boys' sports (IRR = 1.9; 95% CI = 1.7, 2.1). The highest rates of overuse injury were observed in girls' cross-country (19.2/10 000 AEs; 95% CI = 15.0, 24.2), girls' track and field (16.0/10 000 AEs; 95% CI = 13.5, 18.8), and girls' field hockey (15.1/10 000 AEs; 95% CI = 10.2, 21.6). Overuse injury rates were higher for the lower extremity than the upper extremity (IRR = 5.7; 95% CI = 4.9, 6.7) and for the lower extremity than the trunk and spine (IRR = 8.9; 95% CI = 7.3, 10.8). CONCLUSIONS: Awareness of the overuse injury risk, as well as prevention and intervention recommendations, is necessary and should be specifically targeted at cross-country, field hockey, and track and field athletes.

Collegiate Athletic Trainers' Experiences Implementing Return-to-Sport Policies and Procedures During COVID-19: A Qualitative Research Study.

CONTEXT: Athletic trainers (ATs) were critical personnel in the development of policies and procedures for the safe return to campus and resumption of sport during the 2020-2021 academic year. Policies focused on preventing the potential spread of COVID-19, as well as screening, testing, and management of cases; however, which aspects of implementation were successful or more challenging was unknown. OBJECTIVE: To identify successes and challenges in the implementation of return-to-sport policies and procedures during the 2020-2021 academic year amid the COVID-19 pandemic. DESIGN: Qualitative study. SETTING: National Collegiate Athletic Association Divisions I, II, and III. PATIENTS OR OTHER PARTICIPANTS: A total of 27 ATs (9 women [33.3%], mean age = 48.5 ± 9.8 years, years of experience = 25.0 ± 10.5) who were in positions of leadership or who were actively involved in developing and then implementing COVID-19 return-to-sport policies and procedures completed Zoom interviews. DATA COLLECTION AND ANALYSIS: Semistructured Zoom interviews were audio and video recorded and later transcribed. The data were analyzed by a team of 4 experienced researchers using the consensual qualitative research approach. Field notes, intercoder reliability, and multiple-analyst triangulation were used to establish data credibility. RESULTS: Emerging themes were implementation of public health interventions, interprofessional collaboration, and advancing the profession of athletic training. Participants described establishing and strengthening collaborations with other health care professionals as well as key stakeholders on campus as a positive outcome of the pandemic, but variations in policies among institutions and states made policy communication and enforcement more challenging. CONCLUSIONS: The ATs played a pivotal role in policy development, communication, and enforcement. Overall, participants took pride in serving as health care leaders for their universities and opening the eyes of colleagues to the breadth of their athletic training skill sets.

Parent decision-making regarding youth sport participation during the COVID-19 pandemic.

PURPOSE: To describe youth sport participation behaviors during the COVID-19 pandemic as reported by parents of youth sport athletes, to examine the association of family demographics with the likelihood of children resuming sports, and to qualitatively report the factors influencing parental decision-making regarding youth sport participation during the COVID-19 pandemic. METHODS: A national sample of parents of youth athletes from across the United States (n=236, age: 39.2±8.1 years, 57.2% female) were recruited to complete an online questionnaire by Qualtrics Online Samples (Qualtrics, Provo, UT) using a combination of actively managed, double-opt-in market research panels. The questionnaire focused on changes in child sport participation and family finances as a result of COVID-19 and included both close-ended and open-ended questions. RESULTS: Most parents (63.1%) reported the time their children spent participating in organized youth sports had decreased because of the COVID-19 pandemic. Three-quarters of parents (75.5%) reported that it was likely that their children would fully resume participating in organized youth sports within the next year. Parents whose financial situation was worsened by COVID-19 were less likely to report that their children would resume sports in the upcoming year. Three domains related to parental decision-making emerged from the open-ended responses: safety, fear, and normalcy. CONCLUSIONS: Understanding the factors influencing changes in youth sport participation during the pandemic can allow systems to implement strategies for safe participation in youth sport and physical activity among children. Encouraging participation in outdoor sports with appropriate safety precautions such as masking, social distancing, and hygiene may reduce fear of participation among parents.

Attitudes and beliefs of little league baseball parents regarding sport specialization and college scholarship availability.

OBJECTIVES: Previous studies of parents of adolescent athletes identified a belief among parents of the importance of early specialization for skill development. However, it is unclear if these attitudes and beliefs are also held among parents of baseball athletes, which is the second-most popular boy's sport in the United States. The purpose of this study was to describe the knowledge, attitudes, and beliefs of parents of Little League baseball players regarding sport specialization and college scholarships. METHODS: Two-hundred and forty-four parents of Little League baseball players (female parents: 60.7%, parent age: 41.1 ± 6.2 years old, male children: 98.0%, child age: 9.5 ± 1.6 years old) completed an anonymous online questionnaire regarding parent attitudes and beliefs on sport specialization and college scholarships. RESULTS: Most parents (72.4%) felt that specialization would increase their child's baseball ability either 'quite a bit' or 'a great deal.' Fewer than half of all parents (42.0%) reported that specialization was either 'quite a bit' or 'a great deal' of a problem. Parents underestimated the availability of Division I college baseball scholarship availability (median [IQR]: 5 [4-10]), compared to the actual value of 11.7 scholarships per Division I roster. Only 10.2% of parents (N = 25) reported that they believed it was 'somewhat' or 'very' likely that their child would receive a college baseball scholarship. CONCLUSION: Further efforts are needed to understand parent attitudes and beliefs regarding sport specialization and college scholarships in various sports to better understand current trends in youth sport participation.
