In recent years, tennis has become a popular sport in China, whether in competitive sports or in the daily fitness of ordinary people is widely welcomed. However, due to the late development of tennis in China, the corresponding tennis teaching resources are relatively scarce, and there are problems such as unbalanced allocation. In view of this situation, this paper puts forward the research on the optimal allocation of tennis teaching resources based on big data. This paper makes an in-depth investigation on the current situation of Tennis Teaching under the background of big data, and analyzes various reasons for the backward allocation of tennis teaching resources. In view of these shortcomings, in order to improve the quality of tennis teaching in China, this paper combines the core concept of tennis teaching and big data technology, puts forward measures to strengthen the optimal allocation of tennis teaching resources, and creatively constructs a new basic principle of tennis teaching based on the background of big data. This paper investigates the current situation of tennis teaching development in 30 colleges and universities in China. Through the analysis results, this paper believes that using big data technology to optimize the allocation of tennis teaching resources can effectively improve the imbalance of existing resources and low learning efficiency.

With the rapid advancement of database theory, this paper uses mathematical algorithm modeling methods, and derives the mathematical XXX derivation. In combination with Android system optimization, the performance is improved through the use of Java language and MySQL database, and XXX empirical formulas are used. Finally, after AP ’ s continuous dynamic interactive communication and tracking statistical comparative analysis, it proves that the physical fitness database algorithm has significant effects. It shows that the real-time health information and exercise effect of the college student’s physical fitness database can help college students develop long-term exercise habits and health. Plays a positive role.

The core strength is a kind of power ability that stabilizes the core part of the human body, controls the movement of the center of gravity, and transmits the strength of the upper and lower limbs. It is a "power source" for human movement. The essence of core strength training is the core stability of the human body. The core strength training was introduced into the practice of competitive sports in China at the beginning of the 21st century. It can be divided into two periods: most of the early people did not really understand the essence of core strength training, and the improvement of physical fitness and sports performance was not significant. The paper uses literature data method, experimental method, mathematical statistics method, etc. to study the effect of core strength training on improving the special quality of female gymnasts.

With the rapid advancement of the theory of teamwork offensive tactics, this article uses computer mathematical statistics and derives from mathematical computer mathematics. In the combination of tactical characteristics, the penalty area scoring optimization model research, through the use of teamwork is the offense The main form of organization before scoring improved performance, using the mid-speed confrontation empirical formula, and finally through calculation and statistical comparison and analysis, it proved that the middle-speed statistical algorithm has a significant effect, and it explained the calculation of the team cooperation attack tactics to organize the middle-speed confrontation. Statistics play a positive role.
