Introduction: Asthma is the most common respiratory disease that costs billions of dollars annually worldwide as it gets. Currently in the world, there are 300 million asthma patients and is predicted by 2025, 100 million people will be added to the population of asthma patients in the world. Obesity is a worldwide health concern. Overweight and obesity are associated with reduced lung function. This practicing that yoga in obese patients is associated with improved lung function and lung volumes increase, it is not clear. The aim of this study was to investigate the effect of 8 weeks of yoga training on spirometric indices and BMI in obese women with asthma.
Methodology: 24 obese women aged 30-60 years with mild to moderate asthma and body mass index (BMI)=31.12+2.14kg/m2 were randomly divided into 2 groups of yoga (n=12) and control (n=12) .Yoga training program four times a week for 8 weeks was conducted under the supervision of Sports Medicine. Spirometric indices and BMI were measured before and after the intervention.
Results: This study showed that eight weeks of yoga training a significantly improved spirometric parameters (FEV1, FVC and FEV1 / FVC) experimental subjects but does not have a significant effect on BMI levels.
Discussion: According to the findings, yoga training a Significantly improved spirometric indices in obese women with asthma but no significant effect in reducing the BMI of patients. So the exercises used in this study because of their impact in reducing stress and thereby reduce airway resistance against air flow can be used as a supplemental therapy in patients with asthma be used to improve and progress.
