What Is the Biomechanics of Walking?

This book is the first professional work on footwear biomechanics in China. It starts from the basic biomechanics of the foot and details the basic theories of foot anatomy, gait, plantar pressure, and lower limb electromyography. The specific design and application of sports shoes are divided into different categories. It provides reliable technical support for sports shoe researchers to develop new products. In addition, this book also discusses the biomechanics and applications of shoe lasts, high heels, and medical orthopedic shoes for the first time, which is of great practical value to technical personnel engaged in footwear research. China's footwear industry is now at a critical stage of industrial upgrading. This book starts with the theoretical and practical links to resolve many contradictions that are difficult for theoretical researchers to face. This book can not only be used by shoe researchers, as a teaching material for sports and footwear colleges, but also as a professional reference book for shoe research and development personnel.

From the moment the shoe was born, the history of continuous reform and development began. The development of China's shoes has gone through a long and complicated process, from ancient clogs to modern handmade shoes, to a wide variety of modern shoes, it can be said that the development of shoes is also a microcosm of social and historical development. In today's society, with the vigorous development of various sports and the gradual improvement of people's requirements for a healthy life, the comfort, safety and durability of shoes have received more and more attention. In recent years, with the increasingly widespread application of new technologies and methods, the transformation of shoes has taken a crucial leap. Related research has gradually received attention from workers in various fields. It covers ergonomics, materials science, kinematics, and bionics. Through years of biomechanical research, the editor explores the differences and commonalities of various types of shoes from the perspective of biomechanics, and proposes corresponding solutions to the design and damage of shoes.
This book summarizes and analyzes the previous research results of biomechanics, systematically summarizes many years of experience, and reflects the latest achievements of biomechanics in footwear research. First of all, each chapter is gradual, deepening, and closely related to the relationship between shoes and biomechanics. Taking Chapter 1 as an example, through the introduction of the structure and physiological function of the foot, the relationship between the biomechanics and the foot is gradually introduced, so as to elicit the composition of each part of the shoe, and then conduct foot biomechanical analysis and research to make the reader more A good understanding of the vital connection between shoes and foot biomechanics. Secondly, this book covers a wide range and explains the differences between different types of sports shoes, including the biomechanical research of more than 10 different types of shoes, such as common jogging shoes, tennis shoes, court shoes, football shoes, ski shoes, and different hardness soles The influence on human function reflects the mainstream direction of biomechanics research on shoes to a certain extent. Third, this book focuses on both theoretical and practical considerations. With the reader's deepening of theoretical knowledge, this book provides a lot of practical reference materials in the corresponding chapters. The publication and distribution of this book provides practical biomechanical basis for the design of shoes to a certain extent, and meets the requirements of ergonomics. It is a distinctive and quality textbook and reference book. Throughout the book, the theme of footwear biomechanics is tightly linked with fluent writing to present the latest trends in contemporary footwear research, which is another feature of the book.

The editor's April 2013 sequence of professional footwear requires professional design. There are many outstanding researchers in footwear biomechanics in the world, but few of them have actually put their results into products. The reason is still insufficient knowledge and grasp of footwear. Shoes are one of the necessities of life that are in close contact with the human body every day. In addition to performing the functions of decorating people's bodies, shoes also have a profound impact on human movement. For professional sports shoes, many people have studied in the world, but few researchers in mainland China. After 30 years of rapid development, China has now become the world's largest footwear industry, and its sports shoes production has also jumped to the top. This is an exciting thing! However, as a footwear researcher, we should also see the disadvantages and bottlenecks of the development of things. The current innovative technology and R & D capabilities of China's footwear industry are still far from those of Western developed countries, especially in the field of professional sports shoes. It is a great surprise to see this manuscript co-authored by Professor Song Yawei of the Nanjing Institute of Physical Education and engineer Wang Zhanxing of the China Leather and Footwear Industry Research Institute.
This book embodies the accumulated experience and exploration of young footwear researchers in mainland China for many years. At the same time, it also specifically discusses the biomechanical theory and design methods of professional sports shoes for different projects, avoiding the evaluation of sports shoes performance from a testing perspective. Traditional path. It proposes some practical and effective solutions for the design of special categories of sports shoes. The book also analyzes and discusses women's high-heeled shoes and medical orthopedic shoes, and its content is very helpful to the theoretical development of product technical personnel in the frontline of footwear research and development. In particular, Professor Song Yawei has a solid theoretical foundation, and Wang Zhanxing's engineers have made in-depth research on footwear. Their cooperation has laid a solid foundation for the success of this book. This book analyzes a large number of basic research results of sports shoes at home and abroad. The views cited in the book are detailed and clear. If you can add more sports medicine and its achievements to the design of footwear comfort and damage resistance, it will be more full. At this point, the two of them should have room for the development of some professional footwear research, and the two experts continue to work hard.
Living abroad for many years, the revitalization of the Chinese footwear industry is my biggest wish. It is very gratifying to see this new book published by the younger generation of scholars. I am invited to present it, and I am glad to present it as a book preface. I am grateful and encouraged!
