Exercise Science (also known as Exercise Physiology) is a popular field within the natural sciences with broad and diverse research questions, academic paths, and career options. For example, understanding the effects of physical inactivity on the health and wellness in people of all ages is becoming increasingly important, given the impact of inactivity, poor nutrition, and overweight/obesity on chronic disease risk and mortality. In addition, ways to improve athletic performance, optimize training adaptations and recovery from exercise, and reduce injury risk are important areas of human performance research. Exercise Scientists study these questions and apply what they learn to improve health, wellness, athletic performance, injury prevention, and injury recovery. They do so by becoming physical therapists, athletic trainers, exercise physiologists, biomechanists, professors, researchers, cardiac rehabilitation specialists, occupational therapists, wellness specialists, and other specialties within the field.
