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.
Descripción general del estudio
Descripción detallada
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
