What is sports medicine?
Author: Yasushi Sera / Publisher: Chugai Igaku-sha
Despite the fact that sports are so familiar to us in our daily lives, when it comes to sports medicine, it suddenly becomes obscure and surprisingly unknown. In addition, there are not many opportunities for medical schools to specialize in sports medicine.
In this book, the author, who is widely active as a sports doctor in Japan and abroad, explains what sports medicine is in an easy-to-understand manner. In fact, the field of sports medicine is very broad and deep. This book is an ideal introduction to the world of sports medicine.
