Asthma and Exercise
Asthma is the most common chronic respiratory disease among children and young adults. There are numerous triggers of asthma. In the physical education field (EIA) exercise induced asthma is a very important disease to understand and help maintain stability. Asthma is a chronic lung disease that makes breathing difficult. During an attack, the linings of the bronchial tubes become inflamed and irritated causing mucus production and the constriction of surrounding muscles. These three factors cause a narrowing of the tubes blocking the amount of air into and out of the lungs. This disease cannot be cured but control and treatment will lessen the severity and frequency of attacks. The exact cause of asthma is unknown, but has been found to run in families. Persons with asthma may be supersensitive to many substances and environmental conditions that are normally harmless. Common triggers are allergens (pollen, molds, animal dander, dust, and dust mites), as well as irritants (smoke, fumes, and strong odors), exercise, stress, and changes in weather and temperature. Also a cold or flu, certain drugs, and food additives can be triggers. There are five classifications of asthma based on severity, 5. Severe persistent, which

If the results of the test are reversed after the use of a inhaled beta-agonist, then the diagnosis is positive. Any further tests would involve an exercise challenge test. Rapid airway warming after exercise causes vascular congestion, increased permeability and edema leading to obstruction of the bronchial tubes. With this information, parents, athletes, and coaches can be better informed of the asthma epidemic that is rising in this country, and will be able to help respond to a person who is having an attack with more knowledge and confidence. Swimming is good because of the lower ventilation volume and the warm humidified water eases breathing. Keep in mind some sports are better for persons with asthma. If the exercise is longer or pre- activity medications were forgotten, additional use of the inhaler may be needed. The use of warm, humidified air lessens the degree of constriction, and lowering the intensity of the exercise will lower the amount of air being ventilated, which will also lessen the severity of the attack.
