Background: Aging is associated with a decline in lung function, primarily due to structural changes and reduced respiratory muscle strength. Studies show that yogic breathing practices, known as pranayama, can cause improvement in ventilatory functions of the lungs as well as respiratory muscle strength. However, there are variations in terms of type of yogic breathing used and the duration for which it was done. “Lung age” was a novel concept introduced to convey the overall functional status of the lungs upon spirometry. This index compares the forced expiratory volume performed by a subject vis-à-vis the expected values for the subject’s physical and ethnic characteristics and derives an estimated age of the lung. No studies on the effect of yoga on lung age have been reported. All these factors necessitated the present study. Objective: The study was conducted with the objective of assessing the effect of combined practice of Bhastrika pranayama (fast breathing, vitalizing pranayama) and Nadishodhana pranayama (slow, alternate nostril breathing, cooling pranayama) for 6 weeks on the maximum voluntary ventilation (MVV) and lung age of young adults. It also sought to quantify the extent of the change. Methods: A prospective cohort study was done on 21 healthy participants aged 18-25 years. Participants underwent a six-week pranayama program consisting of Bhastrika and Nadishodhana. Digital spirometry with RMS Helios 401 was used to measure spirometric lung age and MVV. They were performed at baseline and repeated after 6 weeks. Comparison was done using paired t-test. Extent of change in percentage and difference between lung age and chronological age was also calculated. P-value < 0.05 was considered statistically significant. Results: A small but significant increase (about 6%) in MVV was observed following the pranayama practice, suggesting improved respiratory muscle strength and ventilatory reserve. However, no significant changes were found in spirometric lung age. Conclusion: This study provides evidence that pranayama can enhance respiratory muscle performance, as measured by MVV, in healthy young adults. While further research is needed to explore the long-term effects and potential benefits for older populations, the findings suggest that pranayama may be a valuable adjunct to maintaining respiratory health.
