Writing for coaches, trainers, exercise physiologists, and athletes, Boone (exercise physiology, The College of St. Scholastica) explores the myth that sexual activities have a negative influence on athletic performance. Focusing on the superstition that male athletes hold, he reviews the scientific evidence, addresses the fact that there is limited research on women, and explains the physiology of sexual activity. He then considers whether sex might benefit performance. Annotation ©2008 Book News, Inc., Portland, OR (booknews.com)
