Regular aerobic physical activity in short-term moderate asthma and severe: * Reduce the levels of inflammatory mediators * Improves functional capacity * Improves Quality of Life * Improved lung function * Reduces the sensation of dyspnea * Improves symptoms scores and medication use
Methods: Is designed a randomized clinical trial, efficacy, outpatient physical therapy developed in the Institute of Integrative Medicine Teacher Fernando Figueira (IMIP). A pilot study with 20 participants will be made initially to obtain a sample calculation. Subjectively estimated it will take about 50 participants, with possible losses. Will include children older than eight years, diagnosis of moderate and severe persistent asthma according to criteria of Global Initiative National Asthma (GINA) and forced expiratory volume in one minute (FEV1) below 80% predicted. Will be excluded from the study associated with disease that limits physical activity, such as neuromuscular diseases, congenital or acquired heart disease, chronic lung disease associated exacerbation of the crisis and significant cognitive deficit, which makes the participant to respond adequately to the questionnaire and / or inability to meet the commands. Eligible patients will be randomized into two groups: control group, which is not subjected to any kind of exercise and the intervention group, which will be submitted to aerobic exercise for 30 minutes three times a week for six weeks. The two groups will be evaluated before and at the end of six weeks by testing for 6-minute walk, analysis of dyspnea, questionnaire of quality of life, pulmonary function test (FEV1, FVC), inflammatory markers (cytokine ).

Inflammatory mediators by analyzing cytokines by flow cytometry
Was carried collection of peripheral blood cells separated and analyzed for cytokine flow cytometry method. We evaluated Th1 and Th2 cytokines.
Time frame: six weeks
Distance walked during the 6-minute walk
Before and after 6 weeks of intervention
Time frame: 6 weeks
Changes in lung function
Assessed by spirometry (forced expiratory volume in one second, forced vital capacity and the relationship of these. Besides, peak expiratory flow.
Time frame: Before and after 6 weeks of intervention
Days free of asthma
Measured through a journal that will be recorded days without asthma symptoms such as cough, dyspnea, chest tightness, and use of extra medication.
Time frame: After six weeks
Respiratory pressures maxima
Through the evaluation of the maximum inspiratory and expiratory pressure by manuvacuometro
Time frame: Before and after 6 weeks
Analysis of cytokines
Measured in blood plasma samples and analyzed by flow cytometry
Time frame: Before and after 6 weeks
