Background: Pulmonary function tests [PFTs] are noninvasive tests that examine the functionality of the lungs and provide a precise picture of the respiratory system's efficiency. Core stability [CS] is the capability of transferring forces from the upper to lower extremities and strengthening the lumbopelvic complex while keeping the spine in neutral alignment.
Aim of work: This study investigated the impact of core stabilizing exercises on pulmonary functions in healthy adults aged 18–60 years.
Methods: Seven databases were screened depending on an earlier published protocol. Forced vital capacity [FVC], forced expiratory volume [FEV₁], FEV₁/FVC ratio, peak expiratory flow rate [PEFR], and maximum oxygen volume [VO₂max] outcomes have been extracted from seven studies and synthesized qualitatively and quantitatively.   
Results: From seven studies, two studies revealed a non-significant impact of CS exercise on VO₂max but with considerable heterogeneity; two studies demonstrated a significant effect on PEFR with no heterogeneity; six studies showed a significant impact of CS exercise on FVC but with considerable heterogeneity; four studies demonstrated a significant impact of CS exercise on FEV₁, with no heterogeneity, three studies demonstrated significant efficacy of CS exercises on FEV₁/FVC.
Conclusion: Core stability exercises have a significant impact on FVC, FEV₁, FEV₁/FVC, and PEFR, with no significant effect on VO₂ max.
