These YouTube-videos show examples of "Model Sparring", which involves the demonstration of basic techniques in a fluid sequence. Model Sparring is often used for demonstration exhibitions. In other words, it is used to "show off" Taekwon-Do techniques. For Model Sparring the sequence of techniques is often shown slowly at first, and then repeated in real (i.e. fast) time. This helps the audience to get a better idea, since Taekwon-Do techniques are frequently very fast, and an untrained eye might not appreciate the dexterity and skill of the practitioners. Accuracy and balance are probably the two elements that can make or break good Model Sparring. Also, creativity in counter attacking greatly enhances the performance for the audience, while Taekwon-Do instructors are usually more impressed with the correct use of attacking and blocking tools, targeted at the appropriate vital spots.
