“…Importantly, CHF patients who undergo IMT pre-surgery have fewer pulmonary complications post-surgery [199]. Recent studies are emerging that suggest potential benefits of inspiratory resistance training in healthy older adults as well [84,200]. In older subjects, inspiratory muscle training increases peak inspiratory flow [84].…”

Diaphragm abnormalities in heart failure and aging: mechanisms and integration of cardiovascular and respiratory pathophysiology

Inspiratory function is essential for alveolar ventilation and expulsive behaviors that promote airway clearance (e.g., coughing and sneezing). Current evidence demonstrates that inspiratory dysfunction occurs during healthy aging and is accentuated by chronic heart failure (CHF). This inspiratory dysfunction contributes to key aspects of CHF and aging cardiovascular and pulmonary pathophysiology including: i) impaired airway clearance and predisposition to pneumonia; ii) inability to sustain ventilation during physical activity; iii) shallow breathing pattern that limits alveolar ventilation and gas exchange; and iv) sympathetic activation that causes cardiac arrhythmias and tissue vasoconstriction. The diaphragm is the primary inspiratory muscle, hence, its neuromuscular integrity is a main determinant of the adequacy of inspiratory function. Mechanistic work within animal and cellular models has revealed specific factors that may be responsible for diaphragm neuromuscular abnormalities in CHF and aging. These include phrenic nerve and neuromuscular junction alterations as well as intrinsic myocyte abnormalities, such as changes in the quantity and quality of contractile proteins, accelerated fiber atrophy, and shifts in fiber type distribution. CHF, aging, or CHF in the presence of aging disturbs the dynamics of circulating factors (e.g., cytokines and angiotensin II) and cell signaling involving sphingolipids, reactive oxygen species, and proteolytic pathways, thus leading to the previously listed abnormalities. Exercise-based rehabilitation combined with pharmacological therapies targeting the pathways reviewed herein hold promise to treat diaphragm abnormalities and inspiratory muscle dysfunction in CHF and aging.

“…On the other hand, Albuquerque et al, [15] demonstrates that six weeks of PR-IMT training was enough to improve the inspiratory muscle strength and functional capacity in physically active elderly subjects with intensity of 40%-70% of MIP. Both Souza et al, [3] and Albuquerque et al, [15] showed no change in lung volumes as stated by Enright and Unnithan [12]. In contrast, TURNER et al [8] reported that six weeks training period using PR-IMT in asthmatic patients with a moderate load of 50% improved MIP, tolerance and perception of dyspnea.…”

“…The effectiveness of these devices has been proved in Turner et al, [7,8] which stated that the PR-IMT devices work on improving the maximal inspiratory pressure (MIP). In International Journal of Physical Medicine & Rehabilitation addition, proved that there is an improvement in MIP [3], maximal expiratory pressure (MEP), diaphragm mobility and thickness.…”

“…While, 40% of MIP improves muscle strength, work capacity and power output [12]. According to Souza et al [3], there is an improvement in muscle strength, MIP, MEP and diaphragm thickness in elderly females with duration of eight weeks duration with a moderate intensity of 40% of MIP. On the other hand, Albuquerque et al, [15] demonstrates that six weeks of PR-IMT training was enough to improve the inspiratory muscle strength and functional capacity in physically active elderly subjects with intensity of 40%-70% of MIP.…”

Introduction: Inspiratory muscle training (IMT) devices improve respiratory muscle strength, endurance and exercise capacity on healthy subjects. Because of the limited availability of the effect of IMT devices on healthy subjects with minimal activity level, this study was conducted to evaluate the effects of POWERbreath-plus® and Threshold IMT® on healthy subjects by measuring pre and post Maximal inspiratory pressure (MIP), Maximal expiratory pressure (MEP), Peak Expiratory Flow Rate (PEFR) and Mandatory Voluntary Ventilation (MVV) and to compare their effectiveness.

Association of Low Baseline Diaphragm Muscle Mass With Prolonged Mechanical Ventilation and Mortality Among Critically Ill Adults

et al. 2020

IMPORTANCE Low diaphragm muscle mass at the outset of mechanical ventilation may predispose critically ill patients to poor clinical outcomes. OBJECTIVE To determine whether lower baseline diaphragm thickness (Tdi) is associated with delayed liberation from mechanical ventilation and complications of acute respiratory failure (reintubation, tracheostomy, prolonged ventilation >14 days, or death in the hospital).

Effects of Inspiratory Muscle Training in Elderly Women on Respiratory Muscle Strength, Diaphragm Thickness and Mobility

Abstract: Inspiratory muscle training of moderate intensity improves respiratory muscle strength, diaphragm thickness, and diaphragm mobility in elderly women and it should be considered to minimize changes associated with senescence.
