The aim of this study is to evaluate if physical activity could improve asthma control and management in adults. With this purpose we enroll asthmatic patients between 18-64 years old, and randomized them into 2 groups: in the first, patients will receive some workshops about asthma en physical exercise; in the second no educational intervention will be done. All patients will use a step counter in order to evaluate their activity during the study. Spirometric values and questionnaries about asthma control and quality of life will be recorded for all patients. Finally 2 groups will be comparated in order to search any difference in quality of life and asthma control.

52 asthmatic will be enrolled and randomized into 2 groups. All patients will send a weekly summary of their physical activity (mean number of steps and time of physical activity). All patients will be undergone to a medical visit at month 1 and 3 since study start. In each visit a spirometry, a FeNo, ACQ and AQLQ questionnaires will be done.

The patients of the intervention group will receive 3 workshops about asthma and physical exercise in order to provide information, medical support, and to resolve any question or difficulty about it. The workshops will be al week 1, 2 and 4 since study start.
