Outcome Measures

Primary Outcomes (1)

  • 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.

    [Change from baseline at 8 weeks of intervention and at 16 weeks post intervention]

Secondary Outcomes (9)

  • Change in sedentary behaviour

    Change from baseline at 8 weeks of intervention and at 16 weeks post intervention

  • Change in physical activity levels

    [Time Frame: Change from baseline at 8 weeks of intervention and at 16 weeks post intervention]

  • Change in Health Factors Related to Quality of Life in Asthma

    Change from baseline at 8 weeks of intervention and at 16 weeks post intervention

  • Change in psychosocial symptoms

    Change from baseline at 8 weeks of intervention and at 16 weeks post intervention

  • Change in body composition - Weight

    Change from baseline at 8 weeks of intervention and at 16 weeks post intervention

  • +4 more secondary outcomes

Other Outcomes (7)

  • Changes in Barriers to the practice of Physical Activities of Daily Living

    Change from baseline at 8 weeks of intervention and at 16 weeks post intervention]

  • Change in asthma exacerbation

    Change from baseline at 8 weeks of intervention and at 16 weeks post intervention

  • Change in Behavioral Stage for physical activity practice

    Change from baseline at 8 weeks of intervention and at 16 weeks post intervention

  • +4 more other outcomes

Study Arms (2)

Behavioral Intervention

EXPERIMENTAL

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.

Behavioral: Behavioral Intervention to Increase Physical Activity

Aerobic Training

EXPERIMENTAL

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.

Other: Aerobic Training

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.

Behavioral Intervention

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.

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Participants not physically active;
  • Uncontrolled asthma (ACQ\>1,5);
