(A) Physical fitness is the basis for the formation of tactics

Any competitive sports can not be separated from the technical and tactical support, and the tactical level of a football team often depends on the players' own sports functions, and the physical fitness given to the players by the implementation of different tactics is completely different. In a complete game, the formation of a team's tactics needs not only the guidance of the coach, but also the cooperation of the players. When a player makes a quick counterattack on the court, it takes a short time to achieve unexpected results. If the ball is on their own, they need to complete a series of operations from counterattack to shooting in one go. In this tactic, they generally need less physical strength. However, if the players fail to make achievements in the counterattack, there will be a physical war of attrition. 1997 in the Top Ten Asian World Cup, it was precisely because of the unreasonable distribution of physical fitness that China was unable to implement tactics and missed the final. The unpredictable situation on the court needs to constantly implement new tactics, which requires athletes to ensure abundant physical fitness at any time and respond quickly when they have the opportunity to achieve tactical goals. So physical fitness is the basis of tactical formation.

(2) Physical fitness is the guarantee of tactical quality.

The smooth implementation of football tactics can not be separated from the mutual cooperation between players, which requires players to have abundant physical fitness to ensure that they will not hold the team back and successfully complete the task when implementing tactics. On the football field, whether it is individual combat or collective cooperation, athletes need to use their physical strength to confront their opponents, find suitable opportunities to give play to their advantages and help the team succeed. In recent years, football in China has developed gradually, and Lei Wu, as the pride of China people, has stepped onto the world stage. After careful analysis, it is not difficult to find that his physical quality is indeed much higher than that of ordinary players, which is also the guarantee for him to stand out in his own team. Football game is different from basketball game. In a game, you may not score for an hour or two. Athletes catch up on the pitch, and the completion of such a game is bound to be inseparable from the athletes' daily physical training. Only when athletes' physical fitness is strengthened can the smooth implementation of skills and tactics be guaranteed, and with the improvement of athletes' physical fitness, their awareness of completing tactics will also be enhanced. Therefore, good physical fitness is the key factor to ensure the complete and high-quality implementation of a game.

(C) Physical fitness is the starting point of tactical coordination

On the court, besides individual tactics, it is more important to have local tactics and overall tactics, which determines the competitive level of the team in a certain sense. Through the analysis of the competition, it is not difficult to find that all tactical cooperation can not be separated from the athletes' abundant physical fitness. Especially in local and overall tactics, athletes' physical fitness is the key to the perfect coordination of tactics. Only when every athlete can be in place in time can the smooth implementation of tactics be guaranteed. The overall tactics need the cooperation and restriction between athletes, and the offensive players and defensive players should also cooperate closely. However, in the competition, it is often due to an athlete's lack of physical fitness and slow movement, which can't keep up with the overall layout of the team, leading to uncoordinated team tactics and eventually leading to a big mistake. For example, in the game, if the defender is physically weak, it is easy to cause tactical passivity when offside. In the implementation of an overall tactic, it is also easy for the team to lose the chance to win because of the lack of players' physical fitness. Only when every player has abundant physical strength can we ensure the perfect cooperation in tactical implementation and win the final victory of the game.
