Dynamic and isometric protocols of knee extension: Effect of fatigue on the EMG signal
(2006-01-01)
The objective of this study was to analyze the electromyographic (EMG) signal behavior of rectus femoris (RF), vastus medialis (VM), vastus lateralis (VL) and biceps femoris (caput longum) (BFCL) from nine women during ...
Inspiratory muscle training in patients with chronic obstructive pulmonary disease
(2011)
Respiratory muscle weakness is observed in chronic obstructive pulmonary disease (COPD) patients and contributes to hypoxemia, hypercapnia, dyspnoea, nocturnal oxygen desaturation and reduced exercise performance. During ...
Electromyographic study of the trapezius (pars media) and rhomboideus major muscles in free movements of the head
(1980-12-01)
The authors studied the trapezius (pars media) and rhomboideus major muscles in movements of flexion, extension, inclination and rotation of the head. The electromyographic records demonstrated that referred muscles are ...
Electromyographic study of the trapezius (middle portion) and rhomboideus major muscles in movements of the trunk
(1980-01-01)
The authors studied the trapezius (middle portion) and rhomboideus major muscles in movements of flexion, extension, inclination and rotation of the trunk. The electromyographic records demonstrate that such muscles show ...
Electromyographic study of the trapezius (pars media) and rhomboideus major muscles during respiration
(1980-12-01)
The authors studied the trapezius (pars media) and rhomboideus major muscles during deep inspiration and expiration. The electromyographic records demonstrated that these muscles showed no activity in either phase of breathing.
Histoenzymological and ultrastructural changes in lateral muscle fibers of Oreochromis niloticus (Teleostei: Cichlidae) after local injection of veratrine
(2001-12-01)
The effects of veratrine have been investigated in mammalian, amphibian, and crustacean muscle, but not in fish. In this work, the action of veratrine was studied in the lateral muscle of the freshwater teleost Oreochromis ...
