ABSTRACT: The purpose of this study was to perform a systematic review to determine if respiratory muscle training (RMT) improves sport performance, and respiratory muscle strength and endurance. Methodology followed the Cochrane Collaboration protocol. MEDLINE, CINAHL, SPORTDiscus, PEDro, EMBASE, EBM reviews, and COCHRANE electronic databases were searched until July 2011. Articles were included if: (1) participants were athletes; (2) RMT was compared to sham or control in a randomized controlled design and included outcomes of respiratory muscle and sport performance; (3) published in English. Quality assessment using PEDro and data abstraction was performed by two authors. Outcomes evaluated were measures of sport performance, exercise capacity, spirometry, and respiratory muscle strength and endurance. Metaanalyses were performed on outcomes reported in two or more papers. Results of this systematic review revealed that of the 6,918 citations retrieved from the search strategy, twenty-one met the inclusion criteria. Meta-analyses demonstrated a significant positive effect of RMT on sport performance outcomes of time trials, exercise endurance time and repetitions on Yo Yo tests. Inspiratory muscle strength and endurance improved in most studies, which in part, was dependent on the type of RMT employed. Determination of the type of athlete that may benefit most from RMT was limited by small sample sizes, differing RMT protocols, and differences in outcome measures across studies. In conclusion, RMT can improve sport performance. Closer attention to matching the ventilatory demands of RMT to those required during athletic competition and more aggressive progression of training intensity may show greater improvements in future studies.
