Therefore, the present sudy aimed to invesigate the efect of selected Yoga exercises on thoracic spine alignment and respiratory capacity indices in children with ashma. Methods: The present research is a quasi-experimental sudy with a pretes-postes design. For this purpose, 30 children with mild ashma were included in the sudy purposefully and voluntarily. The subjects were randomly divided into a control group (15 people with Mean±SD age: 11.40±2.13 years) and an experimental group (15 people with Mean±SD age: 10.60±1.76 years). Written informed consent was obtained from the parents of the children. Flexible ruler and spirometry were used to evaluate the curvature of the thoracic spine and respiratory capacity, respectively. To analyze the results of this sudy, we used a dependent t-tes and analysis of covariance at a signifcance level of P<0.05. Results: The results showed a signifcant diference between the two groups in terms of thoracic spine curvature (P=0.001) and increased respiratory capacity (P=0.001). Conclusion: Breathing exercises and asanas of Yoga positively infuence the extensor muscles of the ches and improve lung function and posural misalignment in children with ashma. Therefore, therapiss, coaches, and exercise teachers are recommended to use Yoga exercises to improve the physical, posural, and respiratory indices of children with ashma.
