It demistifies lots of the information of taekwondo training and has some very good tips in all aspects of Taekwondo training.It is a good introduction to periodization, although it over looks the 4 year Olympic plan. He always eluded on how to include all aspects of training, because I was looking for something where all aspects of Taekwondo Training would be included.
As far as strength training, the author didn't have a clue on Sport Specific Training, not knowing how to apply the Principle of Direct Action. Squats, Lunges and the other exercises don't mimic the exact movement of a kick. Bungee Cord, and Air Shied/Heavy Bag Training are Direct Actions(the exact competition technique)
Teaching Methodology is sound, although many of the techniques and tactics are very absolite is todays era. Most of those combinations have not been used at the Elite level for years. He also ignored the all important sparring strategy of Progressions(each scoring techniques set up the next one by telling your opponent who to react), which is the basis of Modern Elite Olympic Taekwondo Competition.
Another thing he ignored was the classifications of exerciese. Indirect Actions-Exercises that aren't related to Taekwondo(to develop General conditioning), Direct Actions-Exercises that are related to taekwondo, but not to competition, such as paddle kicking, Bungee Cord Training, and Flash Drills. And Exercises for Competition-desinged to develop the competition prowess, such as Simulations, Progression practice, and accual sparring. I believe he ignored these aspects because he did not know how to apply them.
The chapter on Mental training was also lacking. He wished to instruct people more on emotion control, concentration and visualization, but bearly touched the subject, taching the most basic of drills. Trance training, Skill accuacition through imagary training, and reaching that "ZONE" are advanced techniques but required to when at the Elite level.
The section on anotomy and injuries was very nice, I had no problems with that.
For all american coaches it is a great introduction to the planning principles. About 90% of American taekwondo coaches "SUCK" in the matter that half the time they don't know what they are doing, and are engaged in "by the feel" training, and refuse to alwknowledge the existance of these advanced training methods. The koreans and many others would consider the information on this book too basic to waste their time with, but American coached who read this book will be amazed that there was so much information they didn't know about.
The Century Video Series "Gold Medal Training Systems" have thousands of examples of competition specific drills, and Tudor Bompa's Theory and Methodology of Training and/or Thomas Kurz's Science of Sports Training can enable you to fully understand the principles only mentioned, and even ignored in this book.
