With the rapid development of Internet technology and the continuous progress of society, machine learning, an artificial intelligence science, plays an increasingly important role in social production, scientific research and daily life. As a classic algorithm in machine learning, support vector machine has developed rapidly based on its unique advantages in small sample, nonlinear and high-dimensional pattern recognition. Table tennis is a sport with fast speed, strong rotation and high requirements for landing. The five elements of "strength, speed, rotation, landing and arc" constitute the basis of table tennis. In the training of young people, basic skills training should be done solidly. Therefore, this paper conducts corresponding research and analysis on table tennis hitting action based on support vector machine model. This paper combines the support vector machine model to study and analyze it. After the research in this paper, it can be seen that the vector machine model can have a certain impact on the table tennis action, and the impact is as high as 67.45%. The research in this paper lays a foundation for future research on table tennis strokes.

The advent of cinema brought with it its use as a propaganda device with which to transmit ideals and doctrines. As a result, newsreels and cinema documentaries were born with the aim of showing the «most relevant» news of the country and abroad, the former with a shorter duration. In this study, the Spanish NO-DO and «Sucesos Argentinos» are used as primary sources to interpret the images and imaginaries that were projected between 1943 and 1955 on female physical culture. The intention is to understand the official discourse of both political regimes on what Argentinean and Spanish society should be like, especially by questioning those meanings about women. In total, 69 issues of NO-DO and 14 editions of «Sucesos Argentinos» have been found which aim to show female physical culture in this period. The female physical culture shown in both newsreels was aimed at strengthening women’s bodies so that they could carry out their «natural functions» (mother, wife, housewife), as well as highlighting their «inferiority» in relation to men through lower impact activities and the homogenization of bodies through clothing, and the performance of the same exercises in synchrony. And all this in countries with different regimes, but which, in the end, coincided.
