Background and Objective: Asthma, obesity or overweight is one of the factors change of heart- espiratory airways that are affected.
Subjects and Methods: This quasi-experimental research was carried out in 2015 using two volunteered groups; experimental (n = 13) and control (n = 13). Weber Group was selected by screening of medical records and clinical examination. The experimental group was subjected to a planned submaximal aerobic activity (45 to 80 percent of maximum heart rate) for two months. Indicators (resting heart rate, systolic blood pressure, and minute ventilation, oxygen consumption and endurance activities) were measured relative to the baseline values using standard methods. Data evaluation and analysis of covariance compared with pre-test and post-test.
Results: The results showed that eight weeks of training significantly decreased resting heart rate, systolic blood pressure. While minute ventilation maximal oxygen consumption and endurance activities (P≤0.05) were significantly increased. But the change indicators in the control group was not significant (P≤ 0/05).
Conclusion: The results showed that the aerobic activity strengthens the respiratory muscles and other physiological factors can cause breathing and heart recovery. Aerobic activity also resulted in favorable changes in cardiovascular parameters and tolerance of overweight women with chronic asthma.
