Research and application of current topics in sports nutrition

The increased focus on fitness and subsequent research in the exercise field has expanded the role of nutrition as it relates to sports medicine. A literature review and application are presented for the anatomical, physiological, and biochemical mechanisms of caffeine in endurance events; iron status and physical performance; regulation of fluid and electrolyte balance during exercise; and stress fractures, calcium, and diet. The goal is to provide dietitians with information that is needed to formulate and rationalize recommendations regarding sports nutrition. An expanded role is offered to dietitians who wish to communicate sports medicine information to other health professionals and to consumers who engage in exercise. Nutrition and sports medicine information could benefit consumers and other health professionals in employee wellness programs in medical centers and organizations, fitness centers, sports medicine clinics, schools, and athletic teams.
