Aerobic Training Versus Behavioral Intervention to Increase Physical Activity in Patients With Asthma
Effects of Aerobic Training Versus Behavioral Intervention to Increase Physical Activity in Patients With Asthma: a Randomized, Blinded Clinical Trial.
University of Sao Paulo General Hospital
56 participants
Aug 23, 2022
INTERVENTIONAL
Conditions
Summary
To compare the effects of aerobic training and behavioural intervention to increase physical activity in the clinical control of asthma and in the quality of life of patients with asthma.
Eligibility
Inclusion Criteria6
- Participants not physically active;
- Uncontrolled asthma (ACQ\>1,5);
- Diagnosis of asthma based on the recommendations of the Global Initiative for Asthma (GINA 2020);
- Be under outpatient follow-up at the Pulmonology or Immunology service of the University of Sao Paulo General Hospital;
- Be under outpatient medical treatment for at least six months, with a stable clinical condition for at least 30 days;
- Being using optimized drug therapy for asthma.
Exclusion Criteria6
- Participation in another research protocol;
- Difficulty in understanding any of the questionnaires used;
- Practitioners of regular physical activity;
- Pregnancy and psychiatric problems that make it difficult to understand the questionnaires and the study protocol;
- Presence of another chronic lung, neurological or musculoskeletal disease that hinders or prevents physical activity;
- Patients who are smokers or ex-smokers (who have quit smoking for less than 1 year or who have smoked more than 15 pack-years).
Interventions
The educational program will consist of 2 classes held once a week, each lasting 90 minutes. The classes will be based on an education videotape, presentations and group discussions. The first class will address the asthma education. The second class will be about the current international physical activity recommendations and the importance and benefits of being physically active. The behavioural intervention will be performed in 8 weekly goal-setting consultation, face-to-face, each lasting until 90 minutes. Patients will be offered a commercially-available activity tracker to wear during 3 days prior to each consultation. According to their own physical activity (PA) data and the behavioural change stage, an individual action plan will be established to increase physical activity. Each participant will receive individual counselling with the goal of increasing participation in PA and reducing their sedentary time.
The same initial educational program described for the Behavioral Intervention group will be delivered to this group. Each aerobic training session will consist of 45 minutes divided into 5 minutes of warm-up, 35 minutes of aerobic exercise and 5 minutes of cool-down. During physical training, heart rate and level of respiratory distress will be monitored. The intensity of aerobic physical training will be based on the heart rate (HR) corresponding to one third of the difference between the anaerobic threshold (LA) and the respiratory compensation point (CRP). The patient may interrupt physical exercise if he presents any clinical symptoms and/or respiratory discomfort, returning as soon as his respiratory condition improves.
