Updated and expanded, this new edition describes the diet, nutrition, and exercise needs as well as the biochemical, nutritional, and clinical assessment of adult athletes. One new chapter addresses hydration and fluid replacement. Another concerns itself with the biochemical and molecular aspects of physical performance and nutrition and the ever increasing value of nutrigenomics. Detailed descriptions of the methods used in collecting data are discussed, including the advantages and limitations of each. The book also summarizes practical evidence-based information relating to nutritional assessment of adult athletes.
