WHAT IS EXERCISED INDUCED BRONCHOCONSTRICTION? Exercise-Induced Bronchoconstriction (EIB) (previously called Exercise-Induced Asthma (EIA), is a temporary narrowing of the lower airways, occurring after vigorous exercise. It may occur in people with asthma or in people without asthma.
What is exercised induced bronchoconstriction?
It may occur in people with asthma or in people without asthma. In people with asthma who experience EIB, exercise is an asthma trigger. This means that for some people during vigorous exercise the small airways in the lungs become red, swollen, and may become blocked with mucus. This narrows the airways and makes it more difficult to breathe.
What is exercise induced bronchitis (EIB)?
Constriction of the airways during an episode of EIB typically causes some or all of the following symptoms: Wheezing (a distinct breathing noise that indicates distress and is also common in asthma) The pathophysiology of exercise-induced bronchospasm is not fully understood.
What are the signs and symptoms of exercise-induced bronchospasm (EIB)?
Among people with asthma, exercise is likely just one of several factors that can trigger breathing difficulties. Most people with exercise-induced bronchoconstriction can continue to exercise and remain active by treating the symptoms with asthma medications and taking preventive measures.
Can exercise trigger bronchoconstriction in asthma?
Can EIB go away?
As many as 90 percent of people with asthma experience EIB. This type of asthma usually hits five to 10 minutes after exercise ends; the symptoms often go away on their own after 30 to 45 minutes of rest.
What triggers EIB?
EIB is caused by the loss of heat, water or both from the airways during exercise when quickly breathing in air that is drier than what is already in the body. Symptoms typically appear within a few minutes after you start exercising and may continue for 10 to 15 minutes after you finish your workout.
How do I get rid of my EIB?
Types of medicines used to treat EIB include:A short-acting bronchodilator. This medicine is taken 15 minutes before exercise and lasts 4 to 6 hours.A mast cell stabilizer. This medicine is taken 15 minutes to 1 hour before exercise and lasts for 4 hours.A long-acting bronchodilator. ... An antileukotriene.
Is EIB life threatening?
It can be life threatening. You may need to be treated in an emergency room. You may need to stay in the hospital. EIB can get in the way of an athlete's ability to take part in sports.
How do you tell if I have EIB?
EIB causes symptoms of coughing, wheezing, chest tightness, and shortness of breath. Patients with EIB may experience symptoms within 5-20 minutes after starting exercise, but usually will have symptoms after exercise stops. EIB may occur more easily on cold, dry days than on warm, humid days.
Can EIB come on suddenly?
They can appear a few minutes after you start exercising or after you finish a workout. Symptoms usually start to improve after about 30 minutes of rest.
How does EIB differ from regular asthma?
EIA describes patients who have underlying asthma, and exercise is a trigger that exacerbates their asthma. EIB describes patients who do not have a history of asthma and who have bronchospasm associated with only exercise. One reason for this differentiation is the treatment of asthma/EIA versus EIB.
What's the difference between asthma and exercise-induced asthma?
Asthma is a chronic respiratory condition that causes inflammation in the airway. Exercise-induced asthma can affect people with and without regular asthma. Exercise-induced asthma makes the bronchial tubes narrow during physical activity, causing symptoms such as wheezing, coughing, and difficulty breathing.
Is exercise-induced asthma real asthma?
Many of these athletes also didn't know they had the condition. The symptoms are easily mistaken for simply being out of shape. Some athletes may even think the symptoms are normal physical responses to exertion. But exercise-induced asthma, or exercised-induced bronchospasm, is a condition for which treatment exists.

Signs and symptoms of exercise-induced bronchoconstriction usually begin during or soon after exercise. These symptoms can last for 60 minutes or longer if untreated.
Does EIB cause dizziness?
Obstructive EIB has been reported in elite Olympic athletes as well as the recreational athlete. Although exercise-induced bronchospasm presents as wheezing, chest tightness, or dizziness during or after exercise, cough post-exercise is a common and an easily detected characteristic of EIB.
Does EIB cause chest pain?
Exercise-induced bronchospasm (also called EIB) happens if the airways in your lungs shrink (get smaller) while you are exercising. If you have EIB, it can be hard for you to exercise for more than 30 minutes. You may have wheezing, difficulty breathing, or chest pain.

These medications are extremely effective in treating or preventing EIB symptoms, so if symptoms do not improve, let your allergist know.
What is EIB asthma?
Exercise-induced bronchoconstriction, or EIB, is the preferred term for what was known for years as exercise-induced asthma. Symptoms develop when airways narrow as a result of physical activity. As many as 90 percent of people with asthma also have EIB, but not everyone with EIB has asthma. Many elite and world-class athletes have EIB – including Olympic medal winners in sports like cross country skiing, figure skating and ice hockey. EIB didn’t hold them back, and it shouldn’t hold you back either. An allergist will customize a treatment plan that allows you to get back to the exercise you love, and feel better while doing it.
How to check how exercise affects your breathing?
To check how exercise affects your breathing, your allergist may measure your breathing before, during and after you run on a treadmill or ride an exercise bike. During the test you will breathe into a tube that connects to a spirometer, a device that measures the volume of air being inhaled and exhaled.
How long does it take for EIB to show up?
Symptoms typically appear within a few minutes after you start exercising and may continue for 10 to 15 minutes after you finish your workout. Anyone can experience these symptoms (especially someone who is out of shape), but with EIB, they are more severe. Wheezing in children after physical activity is often the first symptom of asthma.
What causes EIB in hockey?
In some cases, environmental factors may contribute to EIB. Skaters and hockey players can be affected by a combination of cold, dry air in ice rinks and pollutants from ice-resurfacing machines. EIB in distance runners has been linked to exercising in high-allergen and high-ozone environments. In addition, indoor air with high levels of trichloramine, a chemical used in pool chlorination, has been linked to asthma and EIB in swimmers.

If you have EIB, you may have symptoms within minutes of starting to exercise. The symptoms are the same as asthma symptoms.
Why does breathing in cold air narrow the airways?
Breathing in cold, dry, or polluted air is a main factor. During exercise, more air enters the lungs through the mouth, instead of the nose. The air isn’t warm or moist like air that enters through the nose. The cold dry air causes the airways to narrow.
What is the most common test for lung function?
You may have tests to see how well your lungs work. The most common test is spirometry. Your breathing will be checked at rest and during exercise. This is called an exercise-challenge test.
How to prevent EIB?

What is EIB in a bronchiole?
Exercise-induced bronchospasm (EIB) is a condition in which the bronchi and bronchioles—the airways of the lungs—respond to physical exertion by constricting (narrowing). This sets off wheezing, a feeling of tightness in the chest, and other symptoms that tend to resolve soon after the activity is over. EIB is diagnosed with several of the same ...

Why do people breathe through their mouths?
One theory is the increase in breathing rate that occurs during exercise and the fact that during physical exertion many people tend to breathe through their mouths cause the air that reaches the lungs to be drier than usual. (Inhaling through the nose moisturizes the air.)
How long does it take to do exercise challenge?
You then will participate in some form of activity for six to 10 minutes—often on a treadmill—after which another spirometry measurement will be taken and compared to the first one.
What is the prevalence of EIB?
Asthma is the main co-morbid factor associated with EIB, and EIB is estimated to occur in approximately 90% of patients with asthma.12,19Patients with poorly controlled or severe asthma are more likely to manifest with EIB than patients with well-controlled or milder disease.12,19Consequently, between-country differences in the prevalence of EIB should be considered in the context country-specific asthma control levels.42In children and adolescents with asthma, the prevalence of EIB is estimated to be approximately 20–90%,29,30,35,38with one study reporting that 46.7% of children with asthma display symptoms of EIB compared with 7.4% of those who do not have asthma.30The majority of patients with chronic asthma will likely experience a transient increase in symptoms following an appropriate exercise challenge. EIB is known to hinder children’s participation in vigorous activities. Other risk factors contributing to the prevalence of EIB include allergic rhinitis, a personal history of allergies, history of asthma in a close relative or history of wheeze.20,21,30,35
Why do people with asthma stop exercising?
Many patients stop exercising because of their EIB symptoms. In the 2011 EIB Landmark Survey, 22.2% of children with asthma aged 4−12 years and 31.8% of those aged 13−17 years avoided sports activities as a result of their EIB. As EIB affects up to 90% of patients with asthma,12the potential impact on aerobic exercise participation is substantial. Arguably, patients with asthma and EIB are at greater disadvantage than those with asthma and no EIB, for symptom precipitation during exercise often leads to avoidance of regular exercise and reduced QoL. It is important to raise awareness in primary care settings that EIB restricts exercise in patients with asthma, given the clinical and psychosocial benefits associated with physical activity.
How much is EIB in the general population?
The prevalence of EIB in the general population is approximately 5−20%.19 –23However, because few epidemiological studies differentiate people with asthma from the general population, the true prevalence of EIB within the non-asthmatic general population is poorly understood.12
What are the risk factors for EIB?
Other risk factors contributing to the prevalence of EIB include allergic rhinitis, a personal history of allergies, history of asthma in a close relative or history of wheeze.20 ,21,30,35. Challenges of determining EIB prevalence and future work.
How does exercise help with asthma?
Exercise, in particular swimming,53has been shown to improve lung function and asthma symptoms and outcomes, including QoL in patients with asthma.54An analysis of the impact of an aerobic training programme (N = 101) on asthma-specific health-related QoL, asthma symptoms, anxiety and depression scores in patients with moderate or severe persistent asthma found that aerobic training had an important role in the clinical management of persistent asthma.54Significant (p < 0.001) reductions in physical limitation and symptom frequency (Fig.(Fig.2)2) were reported in the training group compared with the control group. Moreover, only patients from the training group reported reductions in anxiety and depression levels (p < 0.001).54
What should EIB focus on?
For patients without underlying asthma, management of EIB should focus on relief of bronchoconstriction, and the reduction in risk (or prevention entirely) of the occurrence of bronchoconstriction, to allow the patient to continue to engage in physical exercise with minimal respiratory symptoms.
What is EIB in asthma?
EIB is defined as acute airway narrowing (which is transient and reversible) that occurs during or after exercise and can be observed in both patients who have and those who do not have chronic asthma.11,18Typical symptoms include dyspnoea, wheezing, cough, chest tightness, excessive mucus production or the feeling of a lack of fitness when the patient is in good physical condition.12,13EIB reportedly usually occurs within 2−5 min after exercise, peaks after 10 min and resolves in approximately 60 min.
