The whole implementation process of widely applying mathematical methods in various scientific research practices. It means that with the development of human society and the progress of science, mathematics has widely penetrated into natural science and social fields. In other words, numbers are highly abstract, strictly logical and concise. Extensive practicality focuses on the auxiliary tools and expression means for human beings to carry out theoretical thinking, logical branching and understand the objective world, thus reaching the height of standardization system. Due to the continuous development of classical (accurate) mathematics, random (probability) mathematics, fuzzy mathematics and grey system theory, mathematical measurement methods have been widely used in all walks of life, which has made the empirical qualitative description of things develop to the stage of combining quantitative and qualitative science, and enabled natural science, social science and even thinking science to accurately measure and judge the quality of things, thus achieving the goal of eliminating the disadvantages of pure empirical qualitative. At present, the implementation of scientific mathematics in sports field is of great significance to improve sports prediction ability, decision-making ability and work efficiency.
