Skeletal muscles are composed of fibres of different types, each type being identified by the
isoform of myosin heavy chain which is expressed as slow 1, fast 2A, fast 2X, and fast 2B …

Skeletal muscle undergoes profound changes in morphological, physiological, and
biochemical character when subjected to prolonged periods of increased use. Although …

Background Diminished respiratory muscle strength and endurance have been
demonstrated in patients with heart failure. This may contribute to exertional dyspnea and …

In man the diaphragm (DIA) and abdominal muscles comprise approximately 50% slow-
twitch (ST) fibres, whereas a higher proportion (60%) is found in intercostal muscles and the …

Ventilatory muscles can become fatigued, and this can contribute to respiratory failure.
Patients with chronic obstructive lung disease may benefit from improving their ventilatory …

Pulmonary hyperinflation impairs the function of the diaphragm in patients with chronic
obstructive pulmonary disease (COPD). However, it has been recently demonstrated that the …

Inspiratory function is essential for alveolar ventilation and expulsive behaviors that promote
airway clearance (eg, coughing and sneezing). Current evidence demonstrates that …

Study Objective: To examine the effects of targeted inspiratory muscle training on respiratory
muscle function, clinical ratings of dyspnea, and perception of resistive loads in symptomatic …

The diaphragmatic electromyogram was used to detect fatigue of the diaphragm in six
chronic quadriplegics while they breathed for 10 minutes against a variety of inspiratory …
