Exercise Physiology is the study of how exercise affects the functions of the body which can influence health and or performance. Students learn the impact of exercise at the whole body, system, and cellular level. The students can apply this knowledge to work with healthy and clinical populations to impact positive alterations involving various physical activity programs. The knowledge gained in the academic field of exercise physiology may be acquired through the scholarly study of physical activity and through laboratory measurements of various physiological outcomes that can impact health and/or performance. Educating the community, including patients, clients, athletes, children, and older adults on how and why to employ specific types of physical activity to improve performance, health, and well-being relies on application of knowledge gained by professionals in the area of exercise physiology.
