Key Features

  • Presents the connection between exercise, nutrition, and physiology in a way that is ideal for both experienced athletes and newcomers
  • Provides the scientific basis for mitochondrial functions and their relationship to fitness, protein synthesis, quality of life, and the aging process
  • Synthesizes the latest research on nutrition, sports nutrition, super foods, and the brain/body connection
  • Co-Authored by legendary cyclist Greg LeMond, who illustrates key points using his own athletic journey


The Science of Fitness: Power, Performance, and Endurance clearly explains the vital connection between diet and exercise in the human body. With this knowledge, you can use the right exercise and nutrition to obtain a higher quality life, prevent disease, and slow the aging process.

Authored in a straightforward style and with color images throughout, this book explores the cellular science behind fitness, protein synthesis, and healthy living. With it you will learn the most recent and important discoveries in the relationships between physical fitness, nutrition, weight loss, and weight management. It provides key information on the body’s mitochondrial processes and their role in aging, along with well-informed discussions on general nutrition, sports nutrition, exercise physiology, how to enhance athletic performance, and how exercise strengthens the mind.

Whether you are interested in how to eat healthy, train for your first (or next) marathon, take your fitness to the next level, find the best super foods, or simply want to improve your vitality through healthy, doable practices, this book will help you on your journey regardless of age or fitness level.


Trainers, competitive and elite athletes, recreational athletes, students of nutrition, physiology, physical therapy, medicine, and biology as well as PCPs and endocrinologists dealing with diabetes and obesity patients.

Greg LeMond

Greg LeMond is a legendary and pioneering bicyclist, three-time winner of the Tour de France (1986, 1989, and 1990), three-time World Cycling Champion (1979 junior, 1983, and 1989), author of "Greg LeMond's Complete Book of Bicycling”" (1988, with Kent Gordis), founder of the LeMond Fitness company, bicycle technology innovator, and fitness expert. Greg LeMond runs his company at GregLeMond.com, is a leader in the latest training equipment and power (watts) training devices, and has recently reintroduced his brand of LeMond bicycles. He contributes in many cycling periodicals, including Cycling News. He recently joined Eurosport as their Global Cycling Ambassador and as a TV sports commentator. Greg is uniquely qualified to describe the importance of mitochondria during the height of his racing career and also when mitochondrial myopathy resulted in his premature retirement from racing. He will explain why modern athletes need to know the science of fitness.

Mark Hom

Dr. Mark Hom, M.D. is a Johns Hopkins University trained biologist (B.A. in Biology with Honors), an award winning artist (Kenan Art Award, first place), an award winning medical illustrator while attending medical school at the University of North Carolina (a UNC Dean's grant recipient and also a UNC Holderness Fellowship recipient), a practicing interventional radiologist (one of the most in demand medical specialties), an educator of young doctors (an Assistant Professor of Radiology), and an avid fitness cyclist (riding 4,000 miles per year). Dr. Hom will explain how the human body, various organ systems, and individual cells function in the biologic process of exercise. Dr. Hom will show that mitochondria are at the center of cell energy production, metabolism, and athletic performance, as well as an underlying cause of degeneration, aging, and many diseases. He is currently a member of the Department of Radiology at Virginia Commonwealth University in Richmond, VA.
