This course considers the health benefits and risks of different forms of exercise, with a goal of understanding how people should exercise, and how much, depending on their athletic and health goals. It introduces elements of exercise science including the biomechanics of tissues and injuries to develop an understanding of how both the quantity and quality of movement and loading contribute to healthy training and/or injury. Some common injuries in sport such as knee injuries and concussions are used as examples of how various patterns of loading can cause injuries.
