Primitive efforts in sports medicine began almost 5,000 years ago in Eastern Asia. Taoist monks used breathing exercises to clear "congestion" from the organs. The doctors of the Greeks and Romans are attributed to the first conscious efforts in sports medicine. The Greeks knew there was a clear association between a person's endurance level and diet between their overall health. Greek doctors even developed primitive exercise plans for athletes. Other major developments in sports medicine occurred in the Middle Ages during the Renaissance. One main development that came out of the middle ages was the concept that even healthy people needed to exercise to maintain their good health.
