The purpose of this study is to explore the two paradigms and methodology of physical education. To this end, two paradigms of physical education were identified. First, we looked at the limits and problems of the positivism paradigm and quantitative research methods, then the limites and problems of naturalism paradigm. The ideal method of research is a mixture of quantitative and qualitative methods. The two methods of research have complementary relationships. It is difficult to assess a methodology as superior. The best way to match the researcher's research objectives is to do so. If quantitative research methods quantify phenomena and pursue objective, rational and universal values, qualitative research methods focus on qualitative issues and have subjective, qualitative and artistic characteristics. We looked at the empiricism and the naturalist paradigm, respectively, with their own characteristics and problems. The two methodologies-quantitative research and qualitative research based on the paradigm of positivism and naturalism tell us that having our own characteristics and problems, like the human body and mind, actually makes us limit our vision by sticking to one method. Therefore, it is only natural that quantitative and qualitative research methods should be recognized as complementary, not mutually exclusive.
