Effectiveness of yogic exercise on respiratory health indices: A systematic review and meta-analysis of intervention studies

Abstract

Respiratory health is a vital component of overall well-being, with various interventions being explored to enhance pulmonary function. This systematic review and meta-analysis aimed to comprehensively evaluate the impact of yogic exercise on respiratory health indices, focusing on Forced Vital Capacity (FVC), a key measure of lung function. A rigorous search identified 53 relevant intervention studies, which were subjected to thorough assessment and quantitative synthesis. The findings of this meta-analysis revealed a significant and positive effect of yogic intervention on Forced Vital Capacity (FVC). The collective evidence from the included studies demonstrated consistent improvements in FVC following yogic exercise regimens. The magnitude of the observed effect underscores the potential of yogic practices as a beneficial strategy for enhancing respiratory health. The systematic review also explored potential sources of heterogeneity, considered study quality, and assessed publication bias. Sensitivity analyses reaffirmed the robustness of the observed effect on FVC, highlighting the reliability of the results. The implications of these findings are promising, suggesting that the incorporation of yogic exercise into respiratory health interventions could hold substantial clinical and public health value. Further research is warranted to elucidate the underlying mechanisms through which yogic practices exert their positive effects on respiratory health. Additionally, investigations into the optimal types, durations, and frequencies of yogic interventions are essential for refining recommendations in both preventive and therapeutic contexts. In conclusion, this systematic review and meta-analysis provide compelling evidence of the effectiveness of yogic exercise in improving Forced Vital Capacity (FVC), a critical indicator of respiratory health. These findings contribute to a growing body of literature supporting the potential of holistic and non-pharmacological approaches to enhance pulmonary function and overall well-being.
