Sports nutritionist Benardot (Georgia State U.) offers a guide that helps athletes, coaches, and sports medicine professionals understand the nutritional needs for becoming conditioned for a sport and how to do so in a way that lowers common activity-associated health and injury risks. He describes nutrition sources (energy nutrients, vitamins and minerals, fluids and electrolytes, and ergogenic acids); the nutritional aspects of optimal performance, including gastrointestinal function and energy delivery (a new chapter), nutrient and fluid timing, oxygen transportation and utilization, and strategies for anti-inflammation and muscular health (a new chapter); factors affecting nutrition needs, such as travel, high altitude, gender and age, and body composition and weight; nutrition strategies for high-intensity bursts and power and endurance; and nutrition plans for speed and power sports, endurance sports, and combined power and endurance sports. In addition to the new chapters, this edition has updated diet plans and more sport-specific examples. Annotation ©2013 Book News, Inc., Portland, OR (booknews.com)
