- Asthma
- Symptoms
- a reversible narrowing of the airway
- hyper-irritability, coughing, wheezing, breathlessness, or mucus production
- occurs in response to a trigger or allergen
- Measurement
- inhaling into a spirometer and measuring the exhaled volume of air.
- if an individuals expiratory volumes improve after inhaling bronchodilator treatments, they have asthma
- Triggers
- drying of the respiratory airways, due to water loss. Causing an inflammatory response, therefore constricting airway
- Broncho-constriction is brought on after exercise. The link between exercise and asthma is 'EXERCISE INDUCED ASTHMA'
- Other common allergies are: exhaust fumes, air pollutants, dust, hair and pollens.
- EIA is high in cold weather as it is dryer than warm weather. Also chlorine and trigger swimming related asthma
- Treatments
- Medical
- inhaled medication, which are a reliever. Relaxes muscles around the airway.
- normally taken before exercise or in response to symptoms
- Corticosteroids are a 'preventer' medication which improve pre exercise lung function.
- inhaled medication, which are a reliever. Relaxes muscles around the airway.
- Non- Medical
- A warm-up, at least 10-30 minutes at 50/60%, provides a refactory period of up to 2 hours for exercise to occur
- Dietary modification of reducing salt, and increasing fish oils and vitamins.
- Medical
- Inspiratory Muscle Training
- The Relationship between strength or the inspiratory muscles and respiratory effort.
- IMT doesn't cure asthma but increases airflow and alleviates breathlessness
- this is a big factor for elite athletes as the IOC may not approve of pharmaceutical approaches
