Abstract

^{Purpose: The outcome of a game requires multiple games, the outcome of a game requires multiple games, and the outcome of a point game requires at least one shot or multiple shots. In the game, every point is the most basic unit that determines the outcome of the volleyball game. We named the one point competition process as the sub competition process. In order to study the technical and tactical laws used in the Stalemate Stage of the sub competition process of the world's High-Level Women's volleyball team, this paper takes the Stalemate Stage of the sub competition process and the application of technology in the Stalemate Stage as the research content, takes the top three teams of the 2019 World Women's Volleyball League as the research object, and through the reference of relevant literature, Using the methods of literature, video observation, logical analysis and mathematical statistics, this paper takes the data of the Stalemate Stage in the sub competition process of three games and 10 innings between the top three of the 2019 World Women's Volleyball League as the investigation object, compares and analyzes the gains and losses of the technical application of the main attack, secondary attack and response in the attack in the Stalemate Stage of the sub competition process, and finally comes to the following conclusions: 1) In terms of the distribution of attack organization positions in the Stalemate Stage of the sub competition process, the main attackers of the Chinese team mostly attack, while the players of the United States and Brazil attack less. Brazil and the United States play in the stalemate mainly by strong attack, while the Chinese team mainly by hanging ball in the stalemate stage. Most of the hanging balls are active and purposeful attacks, which are flexible and light. In the stalemate stage, the Chinese team has a low rate of defensive kicking in place, resulting in less spiking; In the comparative analysis of the attack effect in the Stalemate Stage of the sub competition process, the direct scoring ability of the American team is stronger than that of the Chinese team, the attack speed of the Chinese secondary attack is faster than that of the American and Brazilian players, the personal ability of the secondary attack is strong, and the attack effect and the application of techniques and tactics are slightly stronger than those of other teams. 2) On the attack system in the Stalemate Stage during the sub competition, in the strong attack organization, the strong attack of the Chinese team at position 4 is easy to be prevented back, and the Brazil team scored well in the strong attack organization at position 4. The Chinese team needs to strengthen the offensive organization in position 2; In the flat attack organization, the Chinese team's No. 3 is close to the body and fast, and the No. 4 is flat and open, with good performance, few mistakes and strong stability. It is a powerful scoring means.}
