Exercise provocation test

Medical prescription required

You will always need a prescription from your doctor for this test. Bring this prescription with you on the day of the test.

Preparation

• Avoid strenuous physical activity in the 4 hours before the test.
• Do not smoke for 4 hours before the test.
• Wear comfortable clothing and shoes.
• You do not need to fast.
• Certain medications must not be taken prior to the test. Your doctor will inform you about this.

Procedure

Duration: 75 minutes

• A staff member checks your baseline lung function (spirometry) before starting the test.
• You then sit on a cycle ergometer (a type of exercise bike).
• A nose clip ensures you breathe only through your mouth.
• You cycle for 6 minutes, with the resistance gradually increased during the first few minutes.
• The cycling will require significant physical effort.
• After the exercise, your lung function will be measured regularly over a 30-minute period.

After the exercise, your baseline lung function is measured regularly over a 20-minute period. The results will help determine whether exercise triggers asthmatic symptoms (exercise-induced asthma).

Safe

The exercise provocation test is a safe procedure. The physical effort involved is demanding but not dangerous. You will be monitored continuously during the test.

Side effects

Airway reactions are possible and will be treated with medication.

Mild breathlessness during and after the test is normal. A bronchodilator will be administered to alleviate this.
