Summary

Many studies have reported the benefits of aerobic and breathing exercises such as, reduction of symptoms and reduced the use of medications, the number of crises, exercise induced bronchoconstriction (EIB), and improvement in health-related quality of life (HRQoL). This study will be a randomized and controlled trial (RCT) with 2 parallel arms and blinded assessment. Fifty-four moderate or severe patients with asthma under optimized medication will be randomly assigned (computer-generated) into either aerobic+breathing exercises (AB) or aerobic+stretching exercises (AS). All patients will receive the same educational session and will perform the physical exercise proposed for the group for 12 weeks, 2 times/week, 60-minute sessions; however, the AB group will perform Buteyko breathing technique and AS will perform muscle stretching exercise. All patients will be assessed to clinical control, quality of life, psychosocial symptoms, pulmonary function, functional capacity, physical activity levels, sleep quality, thoracoabdominal mechanics, hyperventilation symptoms, and asthma exacerbation. The data normality will be analyzed by Kolmogorov-Smirnov. The variables obtained before interventions will be compared using the t-test or Mann-Whitney U-test. Comparisons of the outcomes initial and final data will be analyzed with repeated measures ANOVA with appropriate post hoc test. The significance level will be set to 5% for all tests.

Conditions

• Asthma

Interventions

Type	Name	Description
OTHER	Aerobic and Breathing Exercises	Aerobic exercises will be performed on a treadmill, twice a week, totaling 20 sessions of 60 minutes each. The initial intensity will be 50% to 60% of maximum heart rate and the progression will take place according to the level of effort (Borg) in the last two sessions. In addition, following the aerobic training, Buteyko Breathing Technique also will be performed during 20 minutes each exercise, in the same treatment session. During the first two weeks, the patient will learn the technique supervised by a physical therapist. In addition, the patients will receive a breathing exercise booklet for in-home training. Before and after each session, patients will be evaluated in relation to blood pressure, heart rate, oxygen saturation and asthma symptoms.
OTHER	Aerobic and Stretching Exercises	Aerobic exercises will be performed on a treadmill, twice a week, totaling 20 sessions of 60 minutes each. The initial intensity will be 50% to 60% of maximum heart rate and the progression will take place according to the level of effort (Borg) in the last two sessions. In addition, following the aerobic training, stretching exercises will be performing for major muscle groups, during 30 seconds each one. The patients will receive a stretching exercise booklet for in-home training.
