The Most Highly Cited Publications on Basketball Originate From English-Speaking Countries, Are Published After 2000, Are Focused on Medicine-Related Topics, and Are Level III Evidence.

Purpose: To identify the 50 most highly cited research publications in the sport of basketball.
Methods: Using the Clarivate Analytics Web of Knowledge database and the search term "basketball", we identified 2,704 articles. These articles were filtered by the total number of citations and the top 50 most cited articles with a central focus on basketball were selected for this analysis. For each article, we further identified and analyzed author name, publication year, country of origin, journal name, article type, main research topic area, competitive level, gender of study population, and the level of evidence.
Results: Medicine-related topics, particularly those involving knee injuries, are more common than nonmedical topics (coaching, sports psychology etc.) among the highest cited articles. Articles originated from 13 different countries, with 48% originating in the United States. Only four authors had more than one article included in the top 50 most cited articles.
Conclusion: A majority of the top 50 research articles were from English-speaking countries, published after 2000, primarily focused on medicine-related topics, and were Level III evidence. Publications examining knee injuries were the most highly cited and appear to be of high interest to current investigators. The prestige of an author's name appeared to be less influential to the number of citations. Clinical Relevance: The top 50 most cited articles list will provide researchers, medical students, residents, and fellows with a foundational list of the most important and influential academic contributions to the basketball literature.

Introduction

Basketball was invented in 1891 by Dr. James Naismith. Since then, it has slowly spread throughout the world. The International Basketball Federation estimates that there are currently 450 million players and fans of basketball worldwide. In the United States, nearly 40% of children between the ages of 6 and 14 play basketball. 11 million youth between the ages of 12 and 17 participate in the sport, including the 1 million high school students who play for school-sponsored teams., While basketball provides many benefits to those who participate in it, injuries are common. Yearly, basketball-related injuries result in roughly 340,000 emergency department visits for youth under the age of 24. These injuries often occur in game competition rather than in practice and most commonly effect the lower extremeties.

With such a wide influence, basketball has long been a focus of research in the scientific community. Topics of basketball research have included injury prevalence and prevention, player physiology,, biomechanics,, training methods to optimize development,11, 12, 13 and the characteristics of winning teams., With such a wide scope, the literature on basketball is growing rapidly, and it is nearly impossible to stay up to date on recent publications. Bibliometric analyses provide a helpful way of condensing the ever-growing available research.

Bibliometric citation analyses provide a quantitative method of investigating the impact of scientific articles by analyzing the number of citations. Articles with a high number of citations are often considered the most influential articles in a particular field. Researchers use citation analyses to identify which subtopics are of most interest to fellow investigators, to learn from high-yield articles in an unfamiliar field, and to help students and novice researchers gain foundational knowledge about a topic. These analyses have been widely used in medicine.17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30 Similar analyses have been performed in the fields of ecology, biotechnology,, medical education, soccer, and various others.36, 37, 38, 39 The purpose of this study was to identify the 50 most highly cited research publications in the sport of basketball. The hypothesis of this study was that articles with medicine-related topics would be highly cited.

Methods

Given the public nature of these data, institutional review board approval was deemed exempt by our institutional review board. As described in similar studies conducting bibliometric analyses of orthopedic literature, the Clarivate Analytics Web of Knowledge database was used to gather data and metrics.40, 41, 42, 43, 44, 45, 46, 47 The database was queried on December 14, 2021. All articles containing the word “basketball” in the title were isolated. No date, language, journal, or country of origin restrictions were placed on this search.

This search yielded 2,704 total articles, which were sorted in descending order based on the number of citations. The title and abstract of each article were then reviewed in order to determine its relevance to basketball. Only articles that had basketball as the focus of the study were included. For experimental studies, this was defined as articles that presented independent data for basketball players. If a study was unclear or if there were a question as to whether it should be excluded, the full article was obtained and reviewed by two independent authors to ultimately decide upon inclusion or exclusion. Duplicate studies were removed.

A total of 56 articles were reviewed in order to reach the 50 most cited studies that met the inclusion criteria. These 50 studies were reviewed by two authors to obtain the following information: author name, publication year, country of origin (determined by first author affiliation), journal name, category of research (original research, review article, case study, short communication/technical report, letter to the editors, point-counterpoint, editorial, or thesis), main research topic area (physiology, biomechanics, nutrition, training and testing, sports medicine, performance analysis, sport psychology, coaching, or social sciences), and the level of evidence for clinical articles based on the guidelines published by The Centre for Evidence-Based Medicine (CEBM). The level of evidence was determined by a consensus opinion between the second and third authors, both of which are medical students with research experience who were instructed on how to classify studies by the physicians on this study. If there was still a question of classification, the senior author, an experienced orthopedic surgeon specialized in sports medicine, was consulted. For articles classified as original research, the type of study (observational or experimental), gender of study participants (male, female, or both), competitive level of participants (elite, non-elite, or both), and the age group of participants (youth, adult, or all) were determined. An elite competitive level included participants who were classified as either semi-professional or professional athletes. Youth, high school, college, and recreational basketball players were classified as non-elite. If an article incorporated a systematic approach to reviewing the literature or if a meta-analysis were performed, the article was classified in the “review article” category. The citation density, which represents the number of citations per year since publication for each of the 50 studies, was also calculated and recorded.

Results

Table 1 lists the 50 most cited articles in basketball research. The number of citations per article ranged from 1,017 to 116. The average number of citations was 242.9, while the median was 164.5.

Of the 37 original research articles in our study, 16 were experimental, while 21 were observational. In the original research articles, the investigators conducted their research with male participants (17), female participants (6), or a combination of both male and female participants (14). This research investigated both elite and non-elite competition levels, with non-elite settings being more common (22 to 15). The investigators also conducted these studies with youth and adult groups, with 24 of the studies involving adults and 13 involving youth.

The top 50 most cited articles in basketball covered a variety of different topics. The most common topic of research was sports medicine with 20 articles. The second most common area of research was physiology with 11 articles. Other topics included performance analysis (7), biomechanics (4), coaching (2), training and testing (2), sports psychology (2), and social sciences (2). Ten of the top 50 articles focused on knee-related topics. These articles had an average citation density of 22.1. Of the articles with the 9 highest citation densities, 6 analyzed the knee. Anterior cruciate ligament injuries made up 6 of the 10 knee-related articles. Three articles examined ankle injuries and had an average citation density of 11.9. One article focused on oral injuries and had a citation density of 6.32. No publications exclusively investigated injuries of the upper extremities or trunk.

Discussion

The majority of the research articles included in the top 50 were focused on medicine-related topics. With such a heavy focus on medicine, sports medicine doctors and physicians who treat basketball players could benefit from a study of the articles in our analysis. When the articles related to medicine were analyzed further, it became apparent that interest in knee-related injuries is high. Articles that examined injuries of other parts of the body, including ankle, mouth and shoulder injuries, were less prominent in our analysis. Knee injuries, particularly anterior cruciate ligament injuries, appear to be an area of high interest to current investigators.

Articles in our analysis originated from 13 different countries. Roughly half of all articles were published in the United States, and 35 were published in primarily English-speaking countries. The majority of other countries were European. In comparison, a soccer analysis from Brito et al. found that only 18% of the top 50 articles were published in the United States, while all other articles were published in Europe. These findings may indicate a deficiency in the number of research articles available or simply a lack of interest in research from areas with little to no highly cited publications, such as in Asia. These results may also be explained by basketball’s popularity in a given country.

Finally, the publications included were chosen on the basis of citation numbers alone. This metric, although useful in identifying articles with high levels of influence and utility, is influenced by a variety of factors and should not be used as the sole determinate of article impact. Citation density, among other factors, may be useful to researchers as they seek to obtain the most current view of influential research. Individuals using our analysis should also understand that articles not included in our analysis can be very impactful in their clinical practice and future research, and these articles should be explored further.

Limitations

A limitation to our study, and to bibliometric analysis in general, is the exclusion of newer publications. Newer publications did not have the time to accrue citations and, thus, were excluded from the top 50 articles. However, our analysis did include citation density statistics, which control for the effect of publication year. Further, we have included a table listing the top 20 most-cited articles since 2012 to include these newer articles. Another potential limitation of our study is that we only used one database. The use of other databases may result in slightly different results than our findings; however the Web of Knowledge database is commonly used in bibliometric analyses.40, 41, 42, 43, 44, 45, 46, 47

Conclusion

A majority of the top 50 research articles were from English-speaking countries, published after 2000, primarily focused on medicine-related topics, and were Level III evidence. Publications examining knee injuries were the most highly cited and appear to be of high interest to current investigators. The prestige of an author’s name appeared to be less influential to the number of citations.
