About

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.

Full 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).

Enrollment: 56 estimated patients

Sex: All

Ages: 18 to 65 years old

Volunteers: No Healthy Volunteers

56 participants in 2 patient groups

Behavioral Intervention

Experimental group

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.

Treatment:

Behavioral: Behavioral Intervention to Increase Physical Activity

Aerobic Training

Experimental group

Description:

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.

Treatment:

Other: Aerobic Training
