Details and patient eligibility

About

The purpose of this study is to determine whether a pedometer-based unsupervised exercise program is more effective than a general exercise recommendation to increase lifestyle physical activity in adult patients with asthma.

Full description

The patients will be randomized in two groups: the intervention group will receive a standardized advice to physical activity practice plus pedometers and step goals to achieve over the next twelve weeks and the control group will receive the same standardized advice to physical activity practice and usual care.

Enrollment: 37 patients

Sex: All

Ages: 18 to 65 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Asthma diagnosis for at least 6 months (according to Global Initiative for Asthma criteria)
• Regular drug therapy (inhaled corticosteroids or inhaled corticosteroids plus long-acting beta-agonists)
• Clinical stability during the run-in period (3 weeks)

Exclusion criteria

• Physical activity practice over once a week
• Disabling musculoskeletal disease
• Cardiopathy
• Other lung disease
• More than 10 pack-years of smoking
• Pregnancy
• Refusal to participate

37 participants in 2 patient groups

Pedometer-based prescription

Experimental group

Description:

After baseline assessments, the control group will receive a educational session, regarding important aspects of asthma (symptoms, treatment, exacerbations, triggers, etc) plus a unsupervised exercise prescription (walking, 5 times per week, for at least 30 minutes) and a pedometer-based physical activity prescription, consisting of targets to be achieved (in terms of steps per day).

Treatment:

Behavioral: Pedometer-based physical activity prescription

Control

No Intervention group

Description:

After baseline assessments, the control group will receive a educational session, regarding important aspects of asthma (symptoms, treatment, exacerbations, triggers, etc) plus a unsupervised exercise prescription (walking, 5 times per week, for at least 30 minutes).
