Full-court man-to-man defense tactics is an aggressive and destructive defense tactic, which means that every player immediately defends his adjacent opponent when the attack turns to punctuality, and keeps an eye on the opponent in the whole court, so as to destroy the opponent's attack with the active defense of the individual and the cooperation of the whole team, so as to achieve the goal of changing from defense to attack. This kind of tactical defense has the advantages of wide activity area, fierce competition, high intensity and high cooperation consciousness. It can give full play to the player's specialty and effectively restrict the opponent's activities, disrupt the opponent's deployment and playing habits, and cause the opponent's psychological tension and technical mistakes, so as to take the initiative in the game. Therefore, it is considered as the basketball defensive tactical system with the strongest lethality and better strategic application effect in modern high-level basketball games.
It plays an extremely important role in cultivating basketball players' active, brave and tenacious fighting style, improving their physical fitness and promoting the all-round development of technology.
The "invention patent" of full-court man-to-man defense tactics should belong to China basketball players in the 1950s and 1960s in China. At that time, Yang Boyong and other players often used full court press as the most effective tactical application.
