**Vassilis Mougios** is Professor of Exercise Biochemistry and Director of the Laboratory of Evaluation of Human Biological Performance at the School of Physical Education and Sport Science, Aristotle University of Thessaloniki, Greece. He has been teaching exercise biochemistry, exercise physiology, sport nutrition, and ergogenic aspects of sport to undergraduate and graduate audiences in his home country and abroad for over 30 years. Mougios has been invited to numerous conferences and conducted extensive research on muscle activity, exercise metabolism, biochemical assessment of athletes, and sport nutrition. As a result, he has authored or coauthored over 100 papers in international scientific journals. He is the author of *Exercise Biochemistry*, a book published by Human Kinetics and presently in its 2nd edition. Mougios is a fellow and member of the reviewing panel of the European College of Sport Science. He has served or serves as associate editor for 3 journals, topic editor for another 5 journals, and reviewer for over 40 journals.

## **Preface to "Selected Papers from the 9th Greek Conference of Biochemistry and Physiology of Exercise"**

Exercise biochemistry and physiology is a very active field of scientific endeavor, which, over the past half-century, has contributed immensely to our understanding of how muscle activity alters the way our bodies (and those of other animals) function. On the occasion of its 9th annual conference (held in Thessaloniki, Greece, in October 2019), the Hellenic Society of Biochemistry and Physiology of Exercise invited a number of presenters to publish their work as a full paper in a Special Issue in *Sports*. The present volume is the fruit of that endeavor. It contains 10 original papers on biochemical and physiological adaptations to training in children, adolescents, and adults; exercise testing; and exercise as medicine.

We hope that the present collection will satisfy interested readers and will stimulate fruitful discussion and ideas for future research.
