RESUMO
The aim of this systematic review and meta-analysis is to investigate the efficacy of yogic intervention (YI) on pulmonary functions (PFs) and respiratory muscle strength parameters in healthy individuals. PubMed/Medline, Embase, Google Scholar, SPORTdiscus databases as well as manual searches carried out until March 2020 on yoga AND pulmonary function were included based on Prisma guidelines. Twenty studies were identified potentially relevant. They were systematically reviewed and summarized in tabular form, listing yogic intervention (YI) significant improved forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1); FEV1/FVC; peak expiratory flow rate (PEFR), maximum voluntary volume (MVV), respiratory muscle strength parameters like maximum inspiratory pressure (MIP), and maximum expiratory pressure (MEP or PEmax). There are encouraging results elucidated that yogic intervention improves pulmonary functions and respiratory muscle strength parameters of healthy physically fit individuals significantly.
