Sports nutrition is great if you have an affinity for sports or have been an athlete. This type of degree teaches students about the demanding systems of different types of athletes and the type of nutrition they need.
There are degrees in sports nutrition or just nutrition. Basic nutrition covers the nutritional needs of all types of people--of all ages and health types--and provides training to become nutritionists, dietitians and related fields.
Health and exercise science involves the way health and exercise relate to each other. Good health is hard to have without some degree of exercise, so it is important to have a good handle on this before attempting to work in any related field. Students learn about nutrition, injury prevention, personal training and other subjects related to health and fitness.
Exercise physiology is often offered at a graduate level. It covers metabolism, injury prevention, and research in the field of health and fitness. Biochemistry, nutrition and biology are just a few of the subjects exercise physiology majors need to take.
Kinesiology degrees are for people who want to work behind the scenes in the field of fitness and nutrition. This is the study of the body in motion, and relates to just about every facet of sports, fitness, and health and nutrition.
