With a rigorous and updated approach, the book explores topics such as exercise physiology, energy metabolism, nutritional periodization, evidence-based sports supplementation, precision nutrition, nutritional genomics, gut microbiota, medical ethics, and anti-doping, integrating basic science with clinical practice in a systematic manner.

The structure of the work ranges from biochemical mechanisms that regulate energy production to individualized nutritional intervention protocols for athletes in endurance, strength, power, and weight-class disciplines. Each chapter was developed based on the latest guidelines from the International Olympic Committee (IOC), the International Society of Sports Nutrition (ISSN), and the World Anti-Doping Agency (WADA).

This book is an essential resource for professionals working in high-performance sports and in health promotion for physically active individuals, providing technical tools for clinical assessment, dietary prescription, recovery management, and performance optimization with safety, accuracy, and ethical responsibility.
