Abstract: Selection and application of scientific research methods in sport science and sports science research methods are equally important. The overuse of the quantitative research paradigm in the study of sports science weakens the function of qualitative study. Both quantitative research and qualitative research have their limitations, so their fusion would be the best way to do scientific research. The fusion of qualitative and quantitative research takes two forms: one is their integrated use; the other dealing with qualitative research with quantitative research paradigm. By analyzing quantitative research and qualitative research paradigm, this paper aims to emphasize the value of qualitative research in the field of sports science research. Phenomenological methods, which are based on the theory of phenomenology, are a type of qualitative research. The classic phenomenological methods include the flowing steps: epoché, describing the experience and reduction, subject analysis and reflection, feedback, and writing. Phenomenology methods also have some limitations inevitably, but their focus on the experience and reflection of human being is a very effective way for human to make adjustment and progress constantly. More attention should be paid to the flexible application of qualitative methods when excessive emphasis is given to quantitative research paradigm, and the effective problem-oriented fusion of quantitative research and qualitative research will enrich sports science research method system and improve the level of sports science research.
