Respiratory muscle strength training has recently been reported to reduce persistent dyspnea in individuals with post-COVID-19 symptomology. This study aimed to determine the effectiveness of a 12-week home-based, respiratory muscle strength training program in reducing dyspnea and to determine its feasibility and acceptability. This single-group trial included adults &gt; 4\u2009weeks beyond the acute COVID illness. Participants were assessed in person at baseline, 6, and 12\u2009weeks for dyspnea, pulmonary symptoms, quality of life, pulmonary function, and functional capacity. Participants received inspiratory and expiratory respiratory muscle strength trainers, diaries, weekly phone calls, and were shown how to perform the exercises using a return demonstration during the baseline appointment. Statistical analyses included descriptive statistics and the Friedman test to evaluate changes over time. There was a significant reduction in dyspnea (2.04\u20131.39,\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    \u2009=\u2009.005), pulmonary symptoms (17.6\u201311.7,\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    \u2009&lt;\u2009.001), and a significant increase in the quality-of-life index score (0.682\u20130.752,\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    \u2009=\u2009.013) and visual analog scale (63.1\u201371.57,\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    \u2009=\u2009.004). Significant improvements in peak inspiratory flow (111.24\u2013195.77\u2009l,\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    \u2009&lt;\u2009.001), forced expiratory volume over 1\u2009s (291.29\u2013345.42\u2009l,\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    \u2009&lt;\u2009.001), thoracic expansion (2.71\u20133.88\u2009cm,\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    \u2009&lt;\u2009.001) and the 6\u2009min walk test (300.22\u2013391.57\u2009m,\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    \u2009&lt;\u2009.001) were also found. Study adherence was &gt;95% and feasibility and acceptability scores were high. Home-based respiratory muscle strength training may be an effective, acceptable strategy that can be used as a standalone treatment to reduce persistent dyspnea in post-COVID-19 survivors.
