Exercise physiology studies the body's responses to physical activity, including changes in metabolism and physiology of areas like the heart, lungs and muscles. It also examines structural changes in cells. The field has a long history dating back to ancient cultures that recognized exercise's importance for health. Key developments include ancient Greek and Roman physicians recommending exercise, and early modern physicians writing books on exercise benefits and types. Today, exercise physiology provides a scientific understanding of how the body adapts to exercise and training, which is important for physical education, sports performance and health.
