Exercise
Exercise isn't a new idea. Records of people exercising go back to 1100 B.C., when the Greeks competed in the javelin throw, distance running, archery, and boxing. Hippocrates (460 B.C.-377 B.C.), the father of medicine, wrote that "eating alone will not keep a man well, he must also take exercise." Milo of Croton, in 6 B.C., discovered the Principle of Progressive Overload, in which he carried a calf every day on his shoulders and as it grew into a bull and got heavier, he got stronger (just like adding heavier dumbbells).
Exercise-Induced Asthma
Exercise-induced asthma (AZ-muh) is also called EIA. EIA is a narrowing of the airways (tubes that bring air to your lungs) caused by heavy exercise. Heavy exercise causes you to breathe fast, deep and heavy. This type of breathing quickly cools and dries out the airways leading to your lungs. For some people, cooling and drying of the airways may cause bronchospasm (BRONG-koh-spazm). During bronchospasm, smooth muscles tighten like rubber bands around your airways. This tightening makes the airways too narrow and makes it hard to breathe. EIA is sometimes called exercise-induced bronchospasm (EIB).
