초록
본연구는2018년부터2025년까지해외학술지에게재된피클볼관련논문109편의초록을 대상으로텍스트마이닝기법을활용하여연구동향을체계적으로분석하였다. 분석방법으로는 키워드빈도, TF-IDF, 단어쌍분석을수행하고, 의미연결망분석(연결중심성) 및CONCOR 군집 분석을실시하였다. 첫째, 키워드및단어쌍분석결과injury, sport, activity, player 등의키워드가 높은빈도를보였고, TF-IDF 분석에서는epicondylalgia, rehabilitation, prevention 등부상및재활 관련키워드가상위를차지하였다. 단어쌍분석에서는injury-sport, foot-ankle 등이높은공출현 빈도를보여, 연구주제가부상발생, 참가자특성, 안전문제등으로집중되어있음을확인하였다. 둘째, 의미연결망분석결과injury, sport, player, activity가높은연결중심성을보였으며, 이는해당 키워드들이피클볼연구네트워크의구조적중심역할을한다는점을시사한다. 이와연계된 CONCOR 군집 분석에서는 '부상·의학·안전', '참여자 특성 및 건강·사회적 효과', '교육·기술·프로그램', '훈련·기법·종목비교'의네가지주제군집이도출되었다. 이는해외피클볼 연구가 스포츠 기능을 넘어 교육학, 의학, 사회과학 등 다양한 학문 영역에서 다차원적으로 전개되고있음을보여준다. 본연구는피클볼연구의구조적지형을정량적방식으로시각화하고 분석함으로써, 국내연구자들에게안전성확보, 교육적적용, 참여자다양성확대등실질적인연구 방향을제시하는데기초자료로활용될수있을것이다.
Abstract
This study systematically analyzed international research trends by employing text mining techniques on 109 English-language abstracts of academic papers related to pickleball, published in international journals from 2018 to 2025. The analysis included keyword frequency, TF-IDF, and word-pair analyses, along with semantic network analysis (degree centrality) and CONCOR cluster analysis. First, keyword and word-pair analyses showed high frequencies for core terms such as injury, sport, activity, and player. The TF-IDF analysis ranked injury and rehabilitation-related keywords such as epicondylalgia, rehabilitation, and prevention highly. Word-pair analysis confirmed that research topics are concentrated on injury occurrence, participant characteristics, and safety issues, with high co-occurrence frequencies for combinations like injury-sport and foot-ankle. Second, the semantic network analysis revealed high degree centrality for injury, sport, player, and activity, indicating their structurally central role within the research network. Linked to this, the CONCOR cluster analysis derived four distinct thematic clusters: 'Injury, Medical, and Safety,' 'Participant Characteristics, Health, and Social Effects,' 'Education, Skills, and Programs,' and 'Training, Technique, and Sport Comparison.' This demonstrates that international pickleball research is developing multidimensionally across various academic domains including education, medicine, and social sciences, beyond its basic function as a sport. This study quantitatively visualizes and analyzes the structural landscape of pickleball research, providing foundational data for domestic researchers to establish practical research directions including enhancing safety, applying findings in educational contexts, and expanding participant diversity.
