Do you have Asthma?

Researchers are seeking volunteers to examine how exercise training may improve asthma.

Why is the research being done?

It is well known that exercise has numerous health benefits; however, the effects of exercise on asthma symptoms and inflammation in the lungs is not clear. Previous research suggests that exercise may improve asthma and reduce inflammation in the lungs of those with asthma, but more research is needed.

This research therefore aims to improve our understanding of the role of exercise in those with asthma. We hope to find new ways to manage asthma and to allow for the development of improved management guidelines for health professionals. We seek to compare exercise training at different intensities to find out if they have different effects on asthma.

Who can participate in the research?

  • You must have physician diagnosed asthma.
  • You must be aged between 18 and 55 years.
  • You must not be a current smoker.
  • You must currently be doing less than 90 minutes of cardio each week

What would you be asked to do?

If you agree to participate in this study, we will need to check that the study is suitable for you and to do this we will invite you to come into the research facility at the Hunter Medical Research Institute (HMRI) for a screening visit, which will take approximately 1 hour. During this visit the tests you will perform include:

  • A brief medical examination including measurement of your height, weight and blood pressure;
  • Some breathing tests, which involves you breathing into some tubing. This will allow us to measure your lung function and assess if there is any inflammation in your airways.

If you choose to participate, you will be randomised (like tossing a coin) to one of the three study arms: (i) moderate-intensity exercise training, (ii) vigorous-intensity exercise training, or (iii) control condition (no intervention). This study lasts for three months and involves two visits to HMRI and two visits to The University of Newcastle exercise lab, Callaghan campus for assessments. If you are randomised to one of the exercise groups you will also attend The University of Newcastle exercise lab three times each week (one hour/session), for three months, where you will complete an exercise training program where you will be trained by an exercise physiology student.

Your two visits at HMRI will involve breathing tests, blood tests and a body composition test. We will ask you to complete questionnaires related to your asthma, quality of life, exercise habits and perceptions of exercise before and after the program. There will also be a questionnaire for women only asking about your menstrual history. In addition, we will ask you to complete a food diary for four days before each visit.
