The Technique of Self-defence in Taekwondo
     Kirthanapriya D/O Vasagam (171420035)

Self-defence applications are an important part of any martial arts curriculum. Taekwondo self-defense is known as hosinul and it forms one of the four main principles of the art. Realistic Taekwondo self-defense techniques would be difficult to score in sparring as they are designed primarily to cause injury or quickly incapacitate a dangerous adversary.   

There are two main concepts in Taekwondo self-defense. An experienced Taekwondo practitioner needs to be versed in both as, in a real life combat situation, either may be needed:

• Linear (or hard) techniques
• Circular (or soft) techniques

Linear Techniques

These include mostly punching, kicking, headbutts and other striking maneuvers. Force is met directly with force and all four limbs are involved in stopping an adversary. Taekwondo kicks give superior reach, meaning that an adversary can be stopped at a distance. If the technique is done correctly, adversaries may be incapacitated with a single blow. This is particularly important when fighting multiple opponents, where prolonged grappling would leave the Taekwondo practitioner open to further attack.

Circular techniques

This is where an adversary’s strength is used against him – the harder he attacks the greater the pain he will feel. By intercepting and redirecting the force of an attack, the adversary can be manipulated into a position whereby a lock, stranglehold and/or finishing move can be applied. Grappling techniques are used in the linear approach to self defense both as a means of securing an adversary and freeing oneself from an adversarie’s grip. The advantage of soft self-defense techniques is that damage to the attacker can be limited and, in many cases, no permanent injury need be inflicted. A properly applied stranglehold or joint lock will quickly convince all but the most psychotic of attackers that further aggression would be futile.
