Arm Label

Behavioral Intervention

Aerobic Training

Arm Description

Participants will undergo an eight-week behavioral intervention protocol (once a week) aimed at increasing the level of physical activity, consisting of a brief educational program: brief education for asthma and benefits of physical activity and behavioral intervention based on Social Cognitive Theory and the Theory of Stages of Behavior Change.

Participants will undergo an eight-week aerobic training protocol (twice a week) on a treadmill, 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.

Outcomes

Primary Outcome Measures

Change in asthma clinical control
Clinical control will be evaluated by the Asthma Control Questionnaire (ACQ). The ACQ contains 7 items rated on a 7- point scale (0 = without limitation, 6 = maximum limitation), with a higher score indicating worse control. Scores lower than 0.75 are associated with good asthma control, whereas scores greater than 1.5 are indicative of poorly controlled asthma, and a change of at least 0.5 points in the ACQ score is regarded as clinically significant.

Secondary Outcome Measures

Change in sedentary behaviour
Sedentary behaviour will be objectively quantified using a movement sensor (ActiGraph, Pensacola, USA) for 7 consecutive days on the hip using an elastic belt. Sedentary behaviour will be quantify by the time spent sedentary (<100 counts/min).
Change in physical activity levels
Physical activity will be objectively quantified using a movement sensor (ActiGraph, Pensacola, USA) for 7 consecutive days on the hip using an elastic belt.
Change in Health Factors Related to Quality of Life in Asthma
Health related quality of life will be assessed by Asthma Quality Life Questionnaire (AQLQ). The AQLQ consists of 32 items rated on a 7-point scale (1 = great deal, 7 = not at all) divided into the following 4 domains: activity limitations, symptoms, emotional function and environmental stimuli. Higher AQLQ scores indicate a better quality of life, and treatments resulting in a 0.5-point increase in scores following an intervention are considered to be clinically effective.
Change in psychosocial symptoms
Symptoms of anxiety and depression symptoms will be assessed by the Hospital Anxiety and Depression scale (HADs), which consists of 14 items divided into 2 subscales (7 for anxiety and 7 for depression). Each item is scored from 0 to 3, with a maximum score of 21 points for each subscale. A score greater than 8/9 in each subscale suggests a diagnosis of either anxiety and/or depression.

5. Study Description

Brief 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.
Detailed Description
Adult participants of both genders with moderate to severe asthma, not physically active, will be evaluated after being informed about the study, agreeing and signing the informed consent form. Participants will be randomized to aerobic training or behavioral intervention group. Both interventions will consist of 8 weeks. Aerobic training will be performed on a treadmill (2xweek; 45 min/session). The behavioral intervention will be a program to increase physical activity (1xweek; up to 90 min / session). The maximum HR will be estimated according to the Tanaka's equation (208 - 0.7 x age).

Intervention Type
Behavioral
Intervention Name(s)
Behavioral Intervention to Increase Physical Activity
Intervention Description
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.
Intervention Type
Other
Intervention Name(s)
Aerobic Training
Intervention Description
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.
