Inspiratory muscle training with Powerbreath significantly improved maximal inspiratory pressure, forced vital capacity, and sports performance in physically active, healthy adults.
Meta-Analysis
Does inspiratory muscle training with Powerbreath® improve respiratory parameters and athletic performance in physically active, healthy adults?
Inspiratory muscle training with Powerbreath® improves respiratory parameters and sports performance in physically active, healthy adults.
(PwB) is a sectorized respiratory muscle training tool that uses a resistive load to train IMT. There is currently a growing interest in respiratory muscle training, so we set out to systematically assess the effects of IMT with PwB on respiratory parameters and athletic performance in physically active, healthy adults. Based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline, the Cochrane and PEDro scales to assess methodological quality, effect size using the Rosenthal formula, and the Cochrane tool for estimation of risk of bias, studies searchable in Medline, Web of Science, and Cochrane. In addition, for the performance of the meta-analysis, the documentation and quantification of the heterogeneity in each meta-analysis were directed through the Cochran's Q test and the I2 statistic; in addition, a publication bias analysis was performed using funnel plots. Of the total of 241 studies identified in the search, 11 studies for the systematic review and nine for the meta-analysis met the exclusion and/or inclusion criteria. IMT, with PwB, showed significant improvements in maximal inspiratory pressure (MIP) and substantial improvements in forced vital capacity (FVC) in the meta-analysis results. Also, sports performance was significantly increased by IMT with PwB. In conclusion, the use of PwB is an IMT tool that improves respiratory and sports performance.
Fernández‐Lázaro et al. (Thu,) conducted a meta-analysis in Physically active, healthy adults. Inspiratory muscle training with Powerbreath was evaluated on Maximal inspiratory pressure (MIP), forced vital capacity (FVC), and sports performance. Inspiratory muscle training with Powerbreath significantly improved maximal inspiratory pressure, forced vital capacity, and sports performance in physically active, healthy adults.
