Background & Objective: Asthma is a Lifestyle inflammatory and reversible disease of airways. Change in Lifestyle by increasing obesity and decreasing physical activity is the main cause of its high prevalence. Asthmatic patients are less fit than their healthy control subjects. Evidence reveals the association between mechanical life, inadequate physical activity, and increased daily calorie expenditure with adolescent obesity syndrome, On the other hand, overweight and obesity has increased the risk of asthma and inefficiency of lung function. Therefore, the role of the respiratory system in adjusting the acid-free balance during exercise can be considered very important. If an efficient respiratory system leads to a better refinement of toxic substances, attention to pulmonary capacity and volume in different individuals, and the impact of environmental factors on it seems to be necessary. Accordingly, one of the most critical indicators of respiratory function is vital; vital capacity is a reflection of a large amount of respiratory capacity that results in better air purification in the lagoon of the lungs. Pulmonary vital capacity and output volume (FEV) are a strong indicator of lung function that has been reduced due to obesity and inactive Lifestyle. One of the known methods for the treatment of asthma patients is rehabilitation; rehab programs have added therapeutic value to patients with asthma. They cause a significant improvement in these patients, which is one of the essential components of pulmonary rehabilitation. Therefore, this study aimed to evaluate the effect of aerobic training on pulmonary function (FEF, PEF, MVV, FEV) in middle-aged women with mild asthma.
Methods: This semi-experimental study was performed on two groups of 30 obese women with mild asthma, referring to medical centers in Urmia. The subjects were randomly assigned to control (n = 15) and exercise (n = 15). The exercise group performed aerobic exercise for eight weeks in the form of fast-paced walking and intermittent running and aerobic base movements. The program of each exercise session from the first week to the third week consisted of 50 minutes of aerobic exercise with an intensity of 50% of maximum heart rate. Lasted seven to eight weeks, every 60 minutes of aerobic exercise with an intensity of 70-75% of the maximum heart rate given by the Polar machine was measured. In this study, spirometric measurements used for factors such as expiratory flow, maximum voluntary ventilation, expiratory flow maximal in 75% of the vital capacity, and expiratory volume ratio in the first seconds to mandatory vital capacity. Statistical analysis performed using the Shapiro-Wilk test and covariance analysis, and the significance level was 0.05. Data analyzed by SPSS version 22.
Results: The results showed that MVV, FEF, FEV, and PEF and their changes in pretest and post-test stages after eight weeks of aerobic training evaluated. The results of the covariance analysis showed that there was a significant difference between the two groups of training and control in all the respiratory variables by maintaining the pretest and post-test scores (p<0.05). The findings indicated that eight weeks of aerobic exercise had a significant effect on the increase of MVV (p=0.003), FEF (p=0.024), FEV (p<0.001), and PEF (p=0.002) in the research sample. No significant changes observed in the control group.
Conclusion: Performing asthma exercises can contribute to the improvement of asthma treatment for asthmatic patients. Therefore, considering the beneficial effects of exercise, especially aerobic exercise, the protocol of treatment of asthma patients in our country must also be modified to use sports protocols under the supervision of medical specialists and with their advice. Patients with asthma improve their respiratory rate by participating in the exercise rehabilitation program; they can better handle daily tasks, as a result of the aerobic exercise presented in the present study. Effective treatment intervention for obese people asthma is mild because this exercise volume reduces the body composition index, which is a factor in asthma.
