This edition will be a real treasure for coaches, athletes, students of sports universities and anyone interested in the science of sports and its practical aspects. This book examines the key physiological mechanisms that underlie the training of athletes at a high level. The authors share their knowledge about how different body systems — cardiovascular, respiratory, muscular and nervous — interact and affect physical performance. The reader will learn how the body's adaptation to stress occurs at the cellular level and how this knowledge can be used to optimize the training process. The book is not just a scientific work, but a practical guide that presents techniques and strategies to help athletes achieve maximum results. The authors pay attention to both theoretical aspects and practical recommendations, which makes the material accessible and understandable to a wide audience.

This book will be interesting not only for professional athletes and coaches, but also for amateurs who seek to improve their results in sports. It is suitable for those who want to understand more deeply how their body works during training, and how you can improve your performance using scientifically based methods. Readers interested in topics such as sports medicine, biomechanics, and sports psychology will also find much useful information in this edition. Topics raised in the book are relevant and important for modern sports. In conditions of constant competition and striving for records, knowledge of the physiological foundations of training becomes necessary for success. The authors emphasize the importance of an individual approach to each athlete, emphasizing that there are no universal solutions. This opens up new horizons for coaches and athletes who want to adapt their methods to the unique needs of each athlete. The writing style of the authors is clear and accessible, which makes complex scientific concepts understandable even for those who do not have deep knowledge in the field of physiology. The team of authors includes experts with rich experience in sports science, which adds additional value to the book. Their previous works, such as “Sports Physiology: From Theory to Practice” and “The Psychology of Sport: How to Succeed”, have already won recognition among professionals and sports fans. Thus, “Physiological Foundations for the Training of Qualified Athletes” is not just a book, but a whole world of knowledge that will help readers understand how to properly prepare their body for physical exertion, how to avoid injuries and how to reach new heights in sports.
