Inspiratory muscle training improves breathing pattern during exercise in COPD patients

Assessment of Maximum Dynamic Inspiratory Pressure

“…12 The proper evaluation of the S-Index may uncover valuable information about inspiratory muscle capacity and its impact on overall performance for patients, who ranged from those with disabilities to athletes. [13][14][15] Moreover, a precise assessment can reduce the bias effect, which improves clinical trial outcomes. Thus, the aims of the present study were to investigate the number of inspiratory maneuvers necessary to reach a reliable and maximum S-Index and the influence of a specific inspiratory muscle warm-up on its assessment.…”

Effects of two types of equal-intensity inspiratory muscle training in stable patients with chronic obstructive pulmonary disease: A randomised controlled trial

“…The improvement of exercise capacity may result from the changes of inspiratory muscle strength and breathing pattern. In previous study by Charususin N el [28] there were significant correlations between changes in PImax and changes in breathing pattern and fR at 80% of baseline V'Emax. Changes in breathing pattern at iso-ventilation was also observe in this study.…”

Physical therapy in chronic obstructive pulmonary disease (analysis of the evidence-based medicine)

“…All studies found that pulmonary rehabilitation programs or individual physical therapy programs were effective in improving the quality of life [12][13][14][15][16][17], physical endurance [12][13][14][15][16][18][19][20][21][22][23], respiratory muscle strength [13,18,23], reducing symptoms of CoPd [14,16,19,23], improving the function of external breathing [16,[24][25][26], blood parameters [22,27], cognitive functions [21], functional state of muscles [28], survival rates [29,30], and reducing the number of hospital days [31]. The main part of investigations was devoted to the comparison of therapeutic rehabilitation programs that included several components and referred to stable patients with CoPd.…”
