Sports Nutrition

Course code SPOR3030Units 10Level 3000Faculty of Science and Information TechnologySchool of Environmental and Life Sciences

This course provides a scientific underpinning of sport nutrition guidelines and advice. The course covers a range of topics including measuring nutritional status of athletes, assessment of energy requirements, protein and amino acid needs, iron depletion, water and fluid balance, pre-event nutritional considerations, weight management, eating disorders in athletes, nutrition supplements, nutrition and immune function and the special needs of female, vegetarian, elderly, children and young athletes.

10. describe & discuss the macro energy requirements of athletes
11. critically appraise the methods for acute & longer term weight reduction (body fat) in athletes
12. describe eating disorders & disordered eating in athletes
13. describe & discuss the micronutrient needs of athletes
14. describe the relationship between low body fat composition, intense endurance exercise & the incidence of stress fractures in female athletes from the perspective of nutritional intervention
15. describe the relationship between intense endurance training & iron depletion from the perspective of nutritional intervention
