Two types of step-sparring
Two types of step-sparring are generally used in Taekwondo training: three-step and one-step. In step-sparring, the attacker advances and the defender retreats. Sparring drills are designed to reflect the two possible strategies that may be used a fight. One is to simply attack, the other is to react to the opponent's movements and counter-attack before the opponent can complete his or her attack.
Three-Step Sparring. Three-step sparring allows students to practice the three components of one-step sparring. The first step is to step backward with one foot while keeping the center of mass in place, while executing the specified block. The second step is another step backward, while executing the specified block. This step allows the student to gauge the range for the upcoming counter-technique. The third step is a final step backward, while executing the specified block and a specified counter-technique.
Three-Step Sparring. In one-step sparring, students must reduce the time between blocking and countering. The attacker learns to make a single, explosive attack. The attacker learns to reduce telegraphing of intent to attack while the defender learns to recognize incoming attacks and react accordingly. In one-step sparring, you react to an attack with a defensive block that redirects the attacker's power and opens a target area or you to counterattack.
