Description / Abstract:


According to Dr. Carl Sagan, scientific debates are often settled not by better arguments but by better instruments and research. You hold in your hands a research compendium that is hoped will update and clarify the issues surrounding purposeful protein intakes and resistance trainers—especially strength athletes. Whether this book, being a central resource, will reduce the controversy is anyone's guess. The discussions and debates surrounding dietary protein in sport, particularly for this population, are decades old. They are, in many respects, only recently being settled.

But why is there controversy or even interest? It may have begun long ago with athletes insisting on steak as a pregame meal. Or perhaps Rocky Balboa's ingestion of raw eggs helped ignite athlete interest. The active carbohydrate research, and concerns over dietary fats, from the 1970s through the 1990s sometimes put scientists and practitioners at odds with these "steak-and-egg" focused athletes. During those years, evidence-based practice was not yet in full force and a counterculture to overzealous athletes seemed to crop up.

As time moved on, many scientists started to slowly change their conclusions on purposeful, even ample, protein intakes for athletes. Stable isotope methodologies partly replaced nitrogen balance techniques. A direct look at resistance trainers suggested they differed from other populations. The timing—the windows of opportunity— that surround an exercise bout were acknowledged as important. Different protein types were recognized as possessing different physiological effects that might be used to an athlete's advantage.

And yet, as of the writing of this book, introductory college textbooks use dissuasive language regarding dietary protein, sometimes referencing one another's statements as sources of evidence. Practitioners and health educators continue to counsel athletes that their interest in amino acid building blocks is misguided, unnecessary, and even dangerous (see Chapter 3). There appears to be a gap or disconnect between scientists and the practitioners and educators of at least some sports nutrition groups.

On the opposite end of the spectrum, however, dietary supplement companies and the food industry are spending large sums of money to reach resistance trainers, often with overly positive and even exaggerated marketing messages. Images of anabolic hormone-using athletes on the covers of magazines or in advertisements imply that the protein product they hold is the reason for their dramatic physiques. This not only misleads many athletes and laypersons, but it also serves to confuse them considering the oppositional messages that many practitioners provide. What can be done?

Educating the public, including both practitioners and strength athletes, on what current science is finding on this population is our best approach. Belief, dogma, or even long-embraced professional opinions need to be replaced with a willingness to change our conclusions in the light of new scientific evidence. This is not easy. With hundreds of new studies appearing daily in the National Library of Medicine's PubMed database, it is clear that many bodies of nutritional literature are evolving.

A central resource on the various protein–athlete topics would be invaluable. That is what this book is meant to be. It reviews the science-related history of protein and strength athletes; it analyzes the mechanisms being elucidated on what proteins do in muscle cells; and it offers information on protein efficacy for performance, recovery, and body composition. This book also explores various populations that employ resistance training and dietary protein as interventions. Timing, type, and safety data regarding liberal protein diets and related supplements are included. Finally, the book features sidebars, practical examples, and case studies translating the science into a practical understanding of various protein-related topics.

Jose Antonio and I hope you enjoy learning from this much needed, central resource on dietary protein and resistance training. As you read, we encourage you to form your own conclusions. Remain curious, but employ a high standard, weighing the evidence. The result is a pursuit of truth that can only serve to enhance your performance or your practice.
