This book is a recent addition to the Nutrition in Exercise and Sport series of the CRC Press. The first edition of this book (published in 1997; edited by Wolinksy and Driskell) was among the initial books in this series. The second edition follows in the footsteps of the first edition and extensively updates it and expands on it. The new edition’s format is similar to its predecessor in that several chapters address the potential roles of all vitamins and the trace elements iron, zinc, copper, chromium, and selenium in sports performance. New chapters on choline and iodine and a very interesting chapter on boron, manganese, molybdenum, nickel, silicon, and vanadium are part of this second edition.
In the introductory chapter, Bucci and Turpin set the stage by summarizing the results of several human studies conducted on the ergogenic effects of supplementation with B vitamin combinations, multivitamin-mineral supplements, and vitamin and trace mineral antioxidant supplements. Also, studies on the effects of vitamin and trace element supplementation on immune function in exercising adults are reviewed. A variety of positive and negative results are reported that indicate the rationale and need for further research on the multinutrient dietary supplementation of athletes.
Each of the 19 chapters that make up the core of the book address specific nutrients and provide basic information about nutrient properties, functions, recommended intakes, and potential associations with the demands of sports training and exercise performance. This background information provides a foundation for review and discussion of human and animal research and provides the reader with a balanced perspective on the effects of physical activity on nutrient needs and on the purported rationale for dietary supplementation.
The new chapters are valuable additions. The chapter on choline by Deuster and Cooper provides a concise review of choline and makes a strong case for the need to conduct research on the various forms of supplemental choline and their potential association with the physiologic demands of exercise. Thomson contributed the new chapter on iodine. Although research reports on the iodine needs of athletes are limited, Thomson makes a good case for the possibility that the iodine needs of athletes may be greater than the iodine needs of their more sedentary counterparts. Nielsen’s 33-page chapter on the lesser known trace elements boron, manganese, molybdenum, nickel, silicon, and vanadium is a well-crafted review that will help scientists, educators, practitioners, and athletes sort out fact from fiction on these potentially important and often controversial elements.
Driskell completes the book with a summary chapter that briefly recounts key information from each chapter and leaves the reader with food for thought about the issues surrounding the use of vitamin and mineral dietary supplements. Overall, the editors of this book have assembled a concise, well-organized, and timely publication. Researchers, educators, clinicians, and serious athletes who have an interest in sports nutrition will find this book to be a valuable resource.
