This article considers the interdisciplinary character of sports sciences, which holds a double challenge. On one hand, demonstrating how the analysis of a corpus of scientific texts contributes - without exhausting the magnitude of the scientific work - to a better knowledge of a field of interdisciplinary research: sports sciences. On the other hand, on a methodological level, tools and computer strategies have been developed in order to analyze textual data. This article reveals how interdisciplinarity explicitly appears in scientific papers, not only as a discussion topic, but also as an organizational watchword in sports sciences. Besides, the analysis of this corpus helps to finely characterize active forms of interdisciplinary work organized around hybrid disciplines or specific research subjects.
