Purpose: The purpose of this study is to examine research trends in the field of physical activity (PA) of children and adolescents using topic modeling. Research questions were (1) what were the major research topics of PA in Korean citation index (KCI) and social science citation index (SSCI)? (2) What were hot topics and cold topics in PA research? Method: PA and youth-related peer-reviewed research papers were collected to map out the research trends and topics using the Web of Science database. This study analyzed abstracts of the youth physical activity papers published in KCI (N=967) and SSCI (N=13956) from 2020 to 2017. The data were analyzed using the text-mining package, y-Textminer and the visualization tool, Gephi. Results: Results showed that PA and youth-related scientific papers are classified into five categories: (1) Health outcome studies, (2) Measurement, PA levels & trend studies, (3) Determinants or correlates of PA, (4) Interventions papers, and (5) Policy and practice studies. Conclusions: First, the main topic of children’s and adolescent-related Korean PA research was interventions, while foreign studies focused on determinants of PA and health outcomes. Second, hot topics in PA research were interventions (e.g., children’s activity program, the practice of physical education classes), obesity prevention, and health outcomes (e.g. obesity, after-school exercise, etc.) in Korea. On the other hand, research topics such as policy and practice (e.g., adolescent obesity prevention) and health outcomes (e.g., academic achievement, mental health) showed an upward trend in foreign studies. Third, the cold topic related to PA was the environment and context of physical activity. Research topics on ecological perspectives, children with disabilities, neighborhood parks, etc., were cold topics in Korea. On the other hand, topics on nutrition, childcare environment, and after-school programs were cold topics in foreign studies.
