The Ethical Compass: Establishing ethical guidelines for research practices in sports medicine and exercise science

Objective: Research in sports medicine and exercise science has experienced significant growth over recent years. With this expansion, there has been a concomitant rise in ethical challenges specific to these disciplines. While various ethical guidelines exist for numerous scientific fields, a comprehensive set tailored specifically for sports medicine and exercise science is lacking. Aiming to bridge this gap, this paper proposes a comprehensive, updated set of ethical guidelines specifically targeted at researchers in sports medicine and exercise science, providing them with a thorough framework to ensure research integrity. Methods: A collaborative approach was adopted, involving contributions from a diverse group of international experts in the field. A thorough review of existing ethical guidelines was conducted, followed by the identification and detailed examination of 15 specific ethical topics relevant to the discipline. Each topic was discussed in terms of its definition, consequences, and preventive measures. Results: The research in sports medicine and exercise science has grown significantly, bringing to the fore ethical challenges unique to these disciplines. Our comprehensive review identifies 15 key ethical challenges: plagiarism, data falsification, role of artificial intelligence chatbots in academic writing, overstating results, excessive/strategic self-citation, duplicate publications, non-disclosure of conflicts of interest, image manipulation, misuse of peer review, ghost and gift authorship, inadequate data retention, data fabrication, falsification of IRB approvals, lack of informed consent, and unethical human or animal experimentation. For each identified challenge, we propose practical solutions and best practices, enriched by the diverse perspectives of our collaborative international expert panel. This endeavor aims to offer a foundational set of ethical guidelines tailored to the nuanced needs of sports medicine and exercise science, ensuring research integrity and promoting ethical responsibility across these vital fields. Conclusion: This article represents a seminal contribution to the establishment of essential ethical guidelines specifically designed for the fields of sports medicine and exercise science. This article charts a clear course for researchers, clinicians, and policymakers by integrating these ethical principles at the heart of our scholarly and clinical activities.

Does Neuromuscular Training Reduce the Risk of Lower-Extremity Musculoskeletal Injury in High School Female Athletes With a History of Sport-Related Concussion?

There is a well-established increased risk of lower-extremity (LE) musculoskeletal (MSK) injury following a sport-related concussion (SRC). Neuromuscular training programs improve biomechanics associated with LE MSK injury and reduce LE MSK injury incidence, but their relative effectiveness in athletes with history of SRC is unknown. The purpose of this study was to evaluate LE MSK injury incidence in female adolescent athletes with history of SRC following a neuromuscular training intervention. Prospective case-control. Seventy-seven adolescent female athletes aged 12-18years who participated in soccer, volleyball, or basketball were recruited from a single institutional sports medicine research and performance center to complete a 6-week neuromuscular training program prior to competitive athletic season. Group (Control, History of SRC) comparisons of athlete exposure and relative LE MSK injury risk and rates during the competitive athletic season were assessed. Ten injuries were recorded by 9 athletes. Female athletes who reported history of SRC had increased injury risk (Risk Ratio 3.9, 95% CI, 1.1-13.8, P = .01) and increased injury rate (rate ratio 4.1, 95% CI, 1.1-15.8, P = .03) compared with female athletes without history of SRC. Female adolescent athletes with history of SRC showed a greater risk of LE MSK injury compared with athletes with no history of SRC. Future work is still needed to understand the underlying mechanisms associated with future LE MSK injury following SRC and interventions that ameliorate elevated injury risk.

Publication History and Associated Academic Metrics of Selected Content Speakers at Arthroscopy Association of North America and American Orthopaedic Society for Sports MedicineAnnual Meetings

Background Annual meetings held by the Arthroscopy Association of North America (AANA) and the American Orthopaedic Society for Sports Medicine (AOSSM) are important platforms for showcasing relevant sports medicine innovation and research. While meeting planning committees likely consider multiple factors when selecting content speakers, it may be assumed that these speakers are well-published or have an academic reputation on their topic of presentation. Hypothesis/Purpose To assess the peer-reviewed publication history and associated academic metrics of selected content speakers of prominent sports medicine society meetings and to identify content areas that lack speakers with previous peer-reviewed publications on their topic of presentation. Study Design Cross-Sectional Review Methods The 2016-2019 conference programs of AANA and AOSSM annual meetings were screened for selected content speakers. Each selected content speaker was searched in the Scopus database to identify prior peer-reviewed publications that were relevant to their presentation topic. Each selected content speaker, presentation, and content category was analyzed to determine the speakers’ Hirsch index (H-index), number of speakers’ previous topic-specific publications, manuscripts’ weighted citation count (WCC), and number of speakers using means and proportions. Comparisons were performed with two-sample T-tests for continuous variables and two-sample Z-tests for proportions for categorical variables, with p-values less than 0.05 indicating statistical significance. Results Of 432 total lectures, 371 (86%) were given by speakers who were previously published on their topic, leaving only 61 lectures (14%) by speakers without previous topic-specific publication (p=0.0005). Nonoperative sports medicine had the highest proportion (34%, 24/71) of lectures delivered by speakers without prior topic-specific publications. Speakers presenting on the hip had the highest H-index (41.67); speakers presenting on the elbow held the highest average number of prior topic-specific publications (12.17); and speakers presenting on biologics held the highest average WCC (8.56). There were no differences between conferences in regard to the proportion of speakers without previous topic-specific publications, the total average number of prior topic-specific publications per speaker, or the total average WCC. Conclusion The AANA and AOSSM annual meetings largely include selected content speakers with prior peer-reviewed literature. While publication history and associated academic metrics may be factors in speaker selection, each organization likely has its own individual selection criteria for delivering high-quality programs.

Insights into Meniscal Injuries Among Young Football Athletes: A Scoping Review

This comprehensive literature review delves into the prevalence, risk factors, management strategies, and outcomes related to meniscal injuries, particularly focusing on young football athletes.

Research indicates that while meniscal injuries are common among athletes, particularly in contact sports like football, early detection and proper treatment are crucial to mitigate lasting effects. Understanding knee joint anatomy and biomechanics is emphasized, along with the implementation of effective rehabilitation protocols to enhance joint stability and prevent re-injury. In summary, this literature review offers valuable insights into the multifaceted nature of meniscal injuries among young football athletes. By synthesizing evidence from diverse sources, it contributes to a deeper understanding of the epidemiology, management, and rehabilitation of meniscal injuries, informing clinical practices and guiding future research in sports medicine

Where is the Sport Science in American Football?

Despite enormous revenue production and a recent trend of investment in sport medicine research, American football has yet to make a measurable investment in sport performance science research. As a result, available knowledge is presently skewed toward technical and tactical domains, with very little knowledge development occurring in other areas within the sport science realm. In this editorial, we discuss plausible contributing factors to the current situation, and suggest ways to resolve this issue and move forward for the betterment of the sport.

Diversity Within the Field of Orthopedic Sports Medicine: A Systematic Review.

Orthopedic surgery is among the least diverse specialties in medicine. This systematic review analyzes gender, racial, and ethnic diversity within orthopedic sports medicine and aims to raise awareness and provide guidance for future strategies that support underrepresented minorities in medicine (URMs) and women in joining the orthopedic sports medicine workforce. We hypothesize that at all tiers of training, there is a lack of gender, racial, and ethnic parity in academic rank, leadership positions, and research productivity. A search of all published literature in the English language from PubMed, Embase, Cochrane, and Scopus databases, between January 1, 2010, and August 18, 2023, was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Included studies presented demographics regarding diversity within orthopedic sports medicine and provided trends in applicants, attendings, leadership, and/or research. Bias was assessed using the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) study checklist. Thirteen studies published between 2016 and 2023 with STROBE scores 15.5 to 21.5 (70.5% to 97.7%) met criteria, and pertinent data were extracted. The percent of female orthopedic sports medicine surgeons from 2010 to 2019 increased from 5% (n = 138) to 6% (n = 206) with a compound annual growth rate of 0.2% (r2 = 0.97; p < 0.001). Females and URMs are underrepresented at the highest levels of orthopedic sports medicine leadership including department chair (female: 0% [n = 0]), division chief (female: 4% [n = 4]; URM: 3% [n = 3]), and fellowship director (female: 3.3% [n = 3]; URM: 4.4% [n = 4]). Studies from prominent orthopedic sports medicine journals (American Journal of Sports Medicine, Arthroscopy, Journal of Shoulder and Elbow Surgery, and Sports Health) show a 12.1% increase in female involvement in orthopedic sports medicine research from 1972 to 2018; however, this increase captures 59.3% (n = 2,953) females with degrees other than an MD. Although increasingly more females and underrepresented minorities are joining orthopedic sports medicine, the rate of diversification remains slow and current involvement in leadership and research is minimal. Targeted efforts aimed at increasing research opportunities and inspiring interest through mentorship for URMs and females in orthopedics is essential to drive change toward parity. Level IV.

ChatGPT for Sample-Size Calculation in Sports Medicine and Exercise Sciences: A Cautionary Note.

To investigate the accuracy of ChatGPT (Chat generative pretrained transformer), a large language model, in calculating sample size for sport-sciences and sports-medicine research studies. We conducted an analysis on 4 published papers (ie,examples 1-4) encompassing various study designs and approaches for calculating sample size in 3 sport-science and -medicine journals, including 3 randomized controlled trials and 1 survey paper. We provided ChatGPT with all necessary data such as mean, percentage SD, normal deviates (Zα/2 and Z1-β), and study design. Prompting from 1 example has subsequently been reused to gain insights into the reproducibility of the ChatGPT response. ChatGPT correctly calculated the sample size for 1 randomized controlled trial but failed in the remaining 3 examples, including the incorrect identification of the formula in one example of a survey paper. After interaction with ChatGPT, the correct sample size was obtained for the survey paper. Intriguingly, when the prompt from Example 3 was reused, ChatGPT provided a completely different sample size than its initial response. While the use of artificial-intelligence tools holds great promise, it should be noted that it might lead to errors and inconsistencies in sample-size calculations even when the tool is fed with the necessary correct information. As artificial-intelligence technology continues to advance and learn from human feedback, there is hope for improvement in sample-size calculation and other research tasks. However, it is important for scientists to exercise caution in utilizing these tools. Future studies should assess more advanced/powerful versions of this tool (ie,ChatGPT4).

Sports Medicine: Scientometric of 10 Years of Global Scientific Productions.

Sport Medicine maintains an active lifestyle and reduces or inhibits countless age-related changes in physical and physiological function by substituting sports methods for people. Improving the scientific situation in sports medicine over time will lead to progress in the field of prevention and reduction of mortality. This study aimed to analyze sports medicine research in the world in terms of scientometric indicators using the Scopus database. This is a bibilometric study. The study population consisted of all articles indexed in the Scopus citation database in the field of sports medicine, registered by researchers from 2011 to 2020. They used SciVal analytical tool as a bibliometric tool that allows the analysis of publications in various parameters, and VOSviewer and Excel software as drawing all citation maps. The highest increase in scientific production of sports medicine was in 2015. Overall, 1,695 articles were published, which received an average of 13 citations per article. The highest rate of scientific production is related to the United States with 41%, followed by the United Kingdom with 16% and Australia with 9%, with a significant difference in the second and third which indicates the high quality and impact of this group of studies. The British Journal of Sports Medicine has contributed the most to the publication of highly cited articles. The most commonly used terms include "Head Impact", "Athletes", and "Sport Injury". Considering the importance of sports medicine in the prevention, control and treatment of many diseases, as well as the growth of the elderly population, it is necessary to develop research in this area. By identifying the features of highly cited articles in this field, a clear view of the top authors and publications and widely used topics was provided.

Poster 384: Inequalities in the Evaluation of Male vs. Female Athletes in Sports Medicine Research: A Systematic Review

Objectives: Female sport participation has steadily increased over the past several decades; however, inequalities still exist regarding participation rates, social norms, and available resources. It is possible that inequalities between male and female athletes extend beyond the performance of sport and into medical research. Therefore, the purposes of this systematic review were to 1) compare the number of published studies evaluating male vs. female athletes in various sports, and 2) identify which co-ed sports currently under-represent female athletes in the sports medicine literature. Methods: All non-review research studies published from 2017-2021 in six top sports medicine journals were considered for inclusion. Only sports medicine studies that isolated athletes, reported study outcomes specific to male and/or female patients, provided study outcomes for specific sport(s), and evaluated three or fewer different sports, were included. The total number of studies reporting on male and/or female athletes were compared for all sports, and odds ratios (OR) were calculated. Comparisons of study design, level of sport participation, outcomes assessed, and study quality were also made based on subject sex. Results: Overall, 669 studies were included the systematic review. Most of the included studies isolated male athletes (70.7%), while 8.8% isolated female athletes and 20.5% included both male and female athletes. Female athletes were more frequently studied in softball and volleyball, while male athletes were more commonly researched in baseball, soccer, American football, basketball, rugby, hockey, and Australian football. Notably, male athletes were largely favored in baseball/softball (91% vs. 5%, OR=18.2), rugby (72% vs. 5%, OR=14.4), soccer (65% vs. 15%, OR=4.3), and basketball (58% vs. 18%, OR=3.2). Conclusions: Sports medicine research has favored the evaluation of male athletes in most sports, including the majority of co-ed sports. Potential reasons for this inequality of research evaluation include availability of public and database data, financial and promotional incentive, a high percentage of sports medicine clinicians and researchers being male, and sex biases in sport. While the causes of these differences are multi-faceted, researchers should consider both sexes for study inclusion whenever possible and journals should support a more balanced representation of research publications regarding male and female athletes.

Pac-12 Health Analytics Program: An Innovative Approach to Health Care Operations, Data Analytics, and Clinical Research in Intercollegiate Athletics.

The objective of this study was to describe the purpose, methods, and effects of the Pac-12 Health Analytics Program (HAP) approach on sports medicine informatics, research, analytics, and health care operations. Sports injury-surveillance initiatives have been supporting the clinical research community in sports medicine for nearly 4 decades. Whereas the initial systems tracked only a few sports, current surveillance programs have expanded to include entire professional and elite athlete organizations, providing important statistics on sports injury risk management. The HAP is a conference-wide data-sharing and-analytics program. It collects authorized, deidentified clinical data, encompassing multiple domains of sports medicine injury management, including sports injuries and illnesses, concussions, risk exposure, and COVID-19 testing elements. The HAP provides clinicians with access to curated data to inform evidence-based practice and support local health care operations with respect to emerging sports injury trends. The HAP supplies approved research groups with access to a data repository that describes a homogeneous, elite intercollegiate athlete sample, thereby supporting nonresearch clinical initiatives as well as contributions to peer-reviewed research that can improve the health and well-being of Pac-12 student-athletes. The HAP is a novel approach to sports injury epidemiology and surveillance that has allowed the Pac-12 Conference to meet larger objectives regarding improving the student-athlete experience and clinical research among its member schools. Data quality control has improved the accuracy of the data and value to clinical athletic trainers within the conference. Curated dashboards displaying aggregated project data offer clinicians data-driven decision-making tools that help inform sports injury risk management. As of 2021, the HAP had supported more than 3 dozen data requests. These investigations have resulted in numerous peer-reviewed research contributions to the sports medicine community with findings that have great potential to improve the health and well-being of Pac-12 student-athletes.

Age-defying fitness: How can combining resistance and aerobic exercise help elderly adults increase muscle strength?

The population of elderly individuals in the village of Tinggede, Indonesia, continues to increase. It is crucial for the ageing population to maintain good fitness throughout the ageing process. Ageing in the elderly encompasses a range of issues, from declining motor function to muscle strength loss. Therefore, it is important for the elderly to preserve muscle strength through physical exercise to ensure independent functioning. This research aimed to investigate the effects of a combination of resistance and aerobic exercises on muscle strength in healthy elderly individuals. The study involved a sample of 30 male elderly individuals aged 60 years and older. The treatment group was given a combination of resistance exercise and aerobic exercise, while the control group was given aerobic exercise. Resistance exercise is given three times per week with a progressive increase in sets and reps. While aerobic exercise is given seven times per week for 40 minutes per session. Participants were examined for muscle strength before and after the intervention using a digital hand grip dynamometer (DHD). The analysis performed included paired t-test and independent t-test with p &lt;0.05. The results demonstrated a significant increase in hand grip strength among the participants who underwent the exercise programme compared to the control group. These findings suggest that a progressive increase in sets and repetitions for each exercise activity can effectively enhance muscle strength in the elderly. However, it is pivotal to note that this study was limited to a single village. Nonetheless, the exercise combination proposed in this study provides valuable insights for sports medicine research and can be utilised as a reference for designing exercise programmes targeting healthy elderly individuals.

Description, Prediction, and Causation in Sport and Exercise Medicine Research: Resolving the Confusion to Improve Research Quality and Patient Outcomes.

SYNOPSIS: Researchers often assign a label (such as a risk factor or predictor) to a characteristic that is statistically associated with an outcome (such as future injury). Labeling signifies that the characteristic has an established clinical value. More often than not, these labels are assigned prematurely and haphazardly. The rampant practice conflates research goals, the ultimate clinical value of the findings, and many risk factors/predictors that may not warrant the label. To address these issues and improve injury prevention research, we (1) outline the problem; (2) clarify the key differences between the research goals of description, causation, and prediction/prognosis (along with labeling conventions); (3) differentiate the clinical implications for each label; and (4) frame an appropriate scientific process to follow before applying a label.

The bias for statistical significance in sport and exercise medicine.

We aimed to examine the bias for statistical significance using published confidence intervals in sport and exercise medicine research. Observational study. The abstracts of 48,390 articles, published in 18 sports and exercise medicine journals between 2002 and 2022, were searched using a validated text-mining algorithm that identified and extracted ratio confidence intervals (odds, hazard, and risk ratios). The algorithm identified 1744 abstracts that included ratio confidence intervals, from which 4484 intervals were extracted. After excluding ineligible intervals, the analysis used 3819 intervals, reported as 95 % confidence intervals, from 1599 articles. The cumulative distributions of lower and upper confidence limits were plotted to identify any abnormal patterns, particularly around a ratio of 1 (the null hypothesis). The distributions were compared to those from unbiased reference data, which was not subjected to p-hacking or publication bias. A bias for statistical significance was further investigated using a histogram plot of z-values calculated from the extracted 95 % confidence intervals. There was a marked change in the cumulative distribution of lower and upper bound intervals just over and just under a ratio of 1. The bias for statistical significance was also clear in a stark under-representation of z-values between -1.96 and +1.96, corresponding to p-values above 0.05. There was an excess of published research with statistically significant results just below the standard significance threshold of 0.05, which is indicative of publication bias. Transparent research practices, including the use of registered reports, are needed to reduce the bias in published research.

Trends in Patient-Reported Outcomes Measurement Information System (PROMIS) Utilization in Orthopedic Sports Medicine: A Scoping Review.

Background: The Patient-Reported Outcomes Measurement Information System (PROMIS) developed by the National Institutes of Health provides a standardized method for collecting outcomes data from sports medicine patient populations. Methods: The objective of this scoping review is to report on PROMIS utilization in orthopedic sports medicine research and practice. We searched PubMed, ScienceDirect, and Cochrane Library using keywords and database-specific subject headings to identify studies that reported PROMIS utilization. Inclusion criteria were the use or mention of PROMIS in any population of patients commonly treated by orthopedic sports medicine physicians. Results: Following a screening process, we included 67 studies published from 2019 through 2022 in this review. A near-equal distribution of studies was published per year during this period. Twenty-four domains were assessed across the studies. Among studies with adult populations, the Pain Interference (45 studies, 67%) and Physical Function (37 studies, 55%) domains were the 2 most reported by researchers. Upper Extremity (4 studies, 6%) and Mobility (3 studies, 4%) were the 2 most used domains in studies involving pediatric populations. Conclusion: Our results demonstrate consistent utilization of PROMIS domains in the field of sports medicine. Researchers commonly used PROMIS with other legacy measures, comparing the scores to one another to assess responsiveness and validity. This review provides evidence that PROMIS domains are being used to collect data on a variety of factors related to sports medicine patient outcomes that may help physicians better understand the complexities of the recovery and rehabilitation process.

Inequalities in the Evaluation of Male Versus Female Athletes in Sports Medicine Research: A Systematic Review

Background: Female sports participation continues to rise; however, inequalities between male and female athletes still exist in many areas and may extend into medical research. Purpose: The purpose of this study was to (1) compare the number of published studies evaluating male versus female athletes in various sports and (2) identify which co-ed sports currently underrepresent female athletes in the sports medicine literature. Study Design: Systematic review; Level of evidence, 4. Methods: All nonreview research studies published from 2017 to 2021 in 6 top sports medicine journals were considered for inclusion. Sports medicine studies were included that isolated athletes, reported study outcomes specific to male and/or female patients, provided study outcomes for specific sports, and evaluated ≤3 different sports. The total number of studies reporting on male and/or female athletes were compared for all sports, and odds ratios (ORs) were calculated. Comparisons of study design, level of sports participation, outcomes assessed, and study quality were also made according to participant sex. Results: Overall, 669 studies were included the systematic review. Most studies isolated male athletes (70.7%), while 8.8% isolated female athletes and 20.5% included male and female athletes. Female athletes were more frequently studied in softball and volleyball, while male athletes were more commonly researched in baseball, soccer, American football, basketball, rugby, hockey, and Australian football. Notably, male athletes were largely favored in baseball/softball (91% vs 5%; OR = 18.2), rugby (72% vs 5%; OR = 14.4), soccer (65% vs 15%; OR = 4.3), and basketball (58% vs 18%; OR = 3.2). Conclusion: Sports medicine research has favored the evaluation of male athletes in most sports, including the majority of co-ed sports. Potential reasons for this inequality of research evaluation include availability of public data and database data, financial and promotional incentives, a high percentage of male sports medicine clinicians and researchers, and sex biases in sport. While the causes of these differences are multifaceted, researchers should consider both sexes for study inclusion whenever possible, and journals should support a more balanced representation of research publications regarding male and female athletes.

Barriers and Facilitators of Research in Pediatric Sports Medicine Practitioners: A Survey of the PRiSM Society.

Barriers and facilitators to research in sports medicine (SM) by physicians and allied health (AH) professions such as physical therapists and athletic trainers are understudied. The purpose of this research was to examine and compare research barriers, facilitators, and other research related facets including interests, comfort, knowledge, and resources among SM physicians and AH practitioners. Cross-sectional survey. The survey was sent to Pediatric Research in Sports Medicine (PRiSM) members. The survey was designed to ask respondents to identify their top barrier and facilitator to conducting research. Research interest (binary), self-rated comfort reading research articles (0-100 scale), self-rated knowledge conducting research independently (0-100 scale), and available research resources were evaluated. Descriptive statistics, chi-square, and t-tests were used to compare the responses between SM physicians and AH practitioners. The value of p<0.05 was set as a statistically significant criterion. The response rate was 35.7% (N=100). For both SM physicians and AH practitioners, the greatest research barrier was a lack of time. However, the leading research facilitators differed in the two professions. The top research facilitator for SM physicians was availability of research personnel, while availability of research mentoring was selected as a prime facilitator by AH practitioners. There were no differences in research interest between SM physicians (87.0%) and AH practitioners (95.5%, p=0.267). However, self-rated comfort reading research articles was higher in SM physicians (75.6±20.6) than AH practitioners (60.6±28.3, p=0.018). There were no differences in self-rated knowledge conducting research independently between SM physicians (70.2±18.6) and AH practitioners (63.4±24.6, p=0.163). Lack of time was the top research barrier for both SM physicians and AH practitioners. Regarding research facilitators, having available time was the main facilitator for SM physicians while availability of mentoring was the leading facilitator in AH practitioners. 3.
