Defensive techniques are strategies used to protect oneself from physical harm or to avoid conflict. These methods can include blocking, dodging, or using barriers to prevent an attack. In martial arts, for example, practitioners learn various defensive moves to counteract an opponent's actions while minimizing their own risk of injury. In sports, defensive techniques are crucial for preventing the opposing team from scoring. Football, basketball, and soccer all employ specific defensive strategies, such as marking opponents or forming defensive lines, to maintain control of the game and protect their goal. Effective defense requires awareness, quick reflexes, and teamwork.
