I purchased this book for 2200 yen + tax and have not read it. It has been stored in a dark place at home, but please refrain from purchasing if you are overly concerned about its condition. I will place it in a waterproof vinyl bag, protect the corners with cushioning material, and ship it via post in a cardboard envelope. Description: Martial arts, the art of defeating others, and medicine, the art of saving others. These concepts may seem completely opposite, but martial arts is a path to living strongly for oneself, and medicine is a path to living strongly for humanity. Martial arts and medicine are not opposing concepts; they are inseparable for those seeking true strength. This book is structured into three parts: "Kinesiology of Martial Arts," "Anatomy of KO," and "Protecting the Athlete's Life," and it outlines objective facts and scientific principles that serve as clues when pursuing strength. The act of correctly studying the human body and mind will be linked to strength. In the "Kinesiology of Martial Arts" chapter, we explore how top athletes and legendary martial artists have built their strength, along with scientific and medical evidence such as X-rays. The "Anatomy of KO" chapter examines KOs, the highlights of martial arts. By understanding "why people fall" from a fundamental (anatomical) perspective, you can freely and infinitely construct methods to defeat opponents. We also delve into the secrets of improving reproducibility. The "Protecting the Athlete's Life" chapter sheds light on the risks that martial arts inevitably entail, such as punch-drunk syndrome, internal medical conditions, and joint injuries, and outlines methods to minimize them. "Strength with life," "Strength with health." These are the recommendations from a martial arts doctor.
