The authors of this type of reliable book which we can trust are rare for most gives rather vague information and without any studies to substantiate their statements but in this book everything and verifiable sources are all quoted at the end of the book for the most skeptical.
I bodybuildeur and this book suits me perfectly cyclist or a trapeze artist could tell you the same thing.
In short I recommend this book to any athlete of any level wishing to improve performance while preserving physical health and intellectual and even some cases for financial lol.
