What is Asthma?[edit]

Over 2 million Australians are diagnosed with asthma.[1] Asthma is a chronic respiratory disease that occurs when the bronchi passageway of the lungs narrow causing breathing to become difficult.[2] Hyper responsiveness of the bronchi smooth muscles lead to the cause of asthma.[3]

Asthma when participating in Cardio exercise?[edit]

Asthma can be a limiting factor for not participating in physical activity.[4] All asthmatics are encouraged to participate in normal physical activity once their asthma is controlled.[4]

If an asthmatic has asthmatic episode whilst exercising this is called Exercise Induced Asthma (EIA) or Bronchospasm (EIB)[5] 40%- 90% of all asthmatics will suffer from EIA during their life.[5]

The key to participating in exercise is control.

Exercise and Ventolin[edit]

Ventolin (salbutamol) is a short acting Beta2-agonist which causes the smooth muscles surrounding the Bronchi to relax.)[3] Ventolin takes approximately 4 minutes to relieve the effects of an asthmatic episode and lasts between 6-8 hours making it suitable for controlling Asthma whilst exercising.[6] It is recommend that Ventolin be used 10-15 minutes before exercise. [3] It is also recommended that you use Ventolin whilst exercising if you start to feel an onset of an asthma attack. (See symptoms above) [4]

How to control your Asthma whilst exercising?[edit]

-Preparing for exercise[3]

  • Ensure your asthma is well managed, by having a asthma action plan in case of an attack
  • Use Ventolin 10-15 minutes before exercise
  • Commence physical activity with a light warm up consisting of rhythmic light exercise (walking or jogging) followed by stretching.
  • Ensure you are well hydrated before exercising.

What to do if you have an asthmatic episode whilst exercising?[7][edit]

  • Stop what you are doing and remain calm
  • Follow you Asthma Action Plan devised by your local GP
  • If you don’t have an asthma action plan, take 4 separated puffs of your inhaler and wait 4 minutes.
  • If the inhaler has not relieved your asthma take another 4 separated puffs and wait another 4 minutes.
  • If your reliever still has no effect call an ambulance.
  • Remain calm and continue to use your inhaler 4 puffs every 4 minutes.
  • If your asthma is controlled again recommence the physical activity
