Sports & Exercise Science is about understanding how our bodies survive the extreme stresses imposed upon them during sporting activities performed under a wide range of environmental conditions. Sports and Exercise Science includes the study of the body's responses to exercise and the adaptations that occur in response to regular exercise. Sports and Exercise Science also includes the role that regular modest levels of physical activity can play in maintaining health. Exercise involves the integrated actions of all the body's systems, and a knowledge of physiology, biochemistry and nutrition is essential to understand how individuals respond to and adapt to the stress of exercise. The exercise and sport sciences are broadly based, and encompass both basic and applied science from the whole body to the molecular level.
