Kinesiology refers to the study of movement. In American higher education, the term is used to describe a multifaceted field of study in which movement or physical activity is the intellectual focus. Physical activity includes exercise for improvement of health and physical fitness, activities of daily living, work, sport, dance, and play, and involves special population groups such as, children and the elderly; persons with disability, injury or disease; and athletes.
A source like the International Journal of Kinesiology & Sports Science will have articles that cover an array of kinesiology sub-topics and very specific aspects of sports science.
