The recent study by Vašíčová et al. (2017) described novel findings that respiratory muscle training (RMT) improved respiratory muscle strength and swimming performance in an apnea-max swim test in young finswimmers. These positive findings are largely compatible with established literature demonstrating increases in respiratory muscle strength following RMT (HajGhanbari et al., 2013; Illi et a...

We assessed upper airway responses to acute and chronic inspiratory loading. In Experiment I, 11 healthy subjects underwent T(2)-weighted magnetic resonance imaging (MRI) of upper airway dilator muscles (genioglossus and geniohyoid) before and up to 10 min after a single bout of pressure threshold inspiratory muscle training (IMT) at 60% maximal inspiratory mouth pressure (MIP). T(2) values for...

The purpose of the present study was to clarify the influence of inspiratory resistive breathing during exercise under hypoxic conditions on muscle sympathetic nerve activity (MSNA) and blood pressure (BP). Six healthy males completed this study. The subjects performed a submaximal exercise test using a cycle ergometer in a semirecumbent position under normoxic [inspired oxygen fraction (FiO2) ...

abstract background: chronic obstructive pulmonary disease (copd) is currently the fourth cause of mortality worldwide. patients with copd experience periods of dyspnea, fatigue, and disability, which impact on their life. the objective of this study was to investigate the effect of short‑term inspiratory muscle training on exercise capacity, exertional dyspnea, and pulmonary lung function. mat...

BACKGROUND The early institution of inspiratory muscle training on hospitalised patients with no established respiratory deficits could prevent in-hospital adverse outcomes that are directly or indirectly associated to the loss of respiratory muscle mass inherent to a prolonged hospital stay. The objective of the clinical trial is to assess the impact of inspiratory muscle training on hospital ...

Respiratory impairment, due to respiratory muscle weakness, is a major cause of morbidity and mortality in patients with amyotrophic lateral sclerosis/motor neuron disease (ALS/MND). Threshold loading may strengthen the inspiratory muscles and thereby improve patient prognosis. A phase II, double-blind, randomized-controlled trial was undertaken to determine whether a 12-week inspiratory muscle...

Background: Chronic Obstructive Pulmonary Disease (COPD) is a primary lung disease .The hyperinflation induces increased strain on the respiratory muscles, which are forced to work in a limited range of movement with negative pressure/effort relationship, leading to fatigue and increased dyspnoea. So purpose of this study is to assess the effect of Inspiratory Muscle Training on PImax and 6 Min...

OBJECTIVES We tested the hypothesis that inspiratory muscle loading could result in exaggerated peripheral vasoconstriction in resting and exercising limbs and that inspiratory muscle training (IMT) could attenuate this effect in patients with chronic heart failure (CHF) and inspiratory muscle weakness. BACKGROUND Inspiratory muscle training improves functional capacity of patients with CHF, ...

Chronic obstructive pulmonary disease (COPD) is a progressive, common and costly condition. Dyspnoea frequently limits activity and reduces health-related quality of life. In addition to impaired lung function, peripheral muscle deconditioning and respiratory muscle dysfunction also contribute to dyspnoea and reduced exercise capacity. Pulmonary rehabilitation using whole body exercise training...
