EFFORT Asthma: Effects of Diet and Exercise in Asthma (EFFORT)
EFFORT Asthma: Effects of a High Protein/Low Glycemic Index Diet and Physical Exercise in Sedentary Non-obese Asthmatics.
Studieöversikt
Detaljerad beskrivning
After screening and enrollment, a total of 200 Danish sedentary, non-obese asthma patients will be randomized to one of four groups: 1) control group (no intervention), 2) physical exercise intervention, 3) diet intervention (a diet with an overall high content of protein and a low glycemic index) or 4) exercise plus diet intervention.
Asthma is defined as respiratory symptoms and at least one positive asthma test. Patients will continue their regular doses of anti-asthma treatment unchanged throughout the study period. Type of anti-inflammatory medicine will be recorded and the adherence to the therapy will be assessed before the intervention period and at follow-up using questionnaires

Tidsram |
---|---|---|
Airway hyperresponsiveness to mannitol, as measured by an airway provocation test.
Tidsram: Within 10 days (+/- 1 day) of completing the intervention
|
The response-dose-ratio (RDR) will be calculated as the percentage fall in forced expiratory volume in 1 second (FEV1) after the last dose of inhaled dried mannitol powder delivered, divided by the cumulative dose of inhaled mannitol.

Within 10 days (+/- 1 day) of completing the intervention
|
Systemic low-grade inflammation, as measured by serum-levels (in microgram/ml) of high sensitivity C-reactive protein, interleukin 6 (IL-6), IL-8, tumor necrosis factor alpha (TNF-alpha) and leptin.
