The results showed that two eigenvalues 位1, and 位2 approached each other near the switching point between the different muscle contractions and only 位1 exhibited a large value at other phases. The distribution of the principal components also showed a change near the switching point. The fore...
3. When human subjects perform isometric contractions, a pressor response can be maintained beyond the conclusion of the exercise by occluding muscle blood flow. This response is generally attributed to a reflex set up in the muscle by the action of chemical factors on afferent nerves. When ...
Firing rates of motor units and surface EMG were measured from the triceps brachii muscles of able-bodied subjects during brief submaximal and maximal isometric voluntary contractions made at 5 elbow joint angles that covered the entire physiological range of muscle lengths. Muscle activation at the ...
Mesenchymal stem cells(MSCs)are kinds of stem cells that play an important role in regeneration and restoration because of its multi-lineage differentiative capacity. They have the potential to differentiate to form connective tissues, skeletal muscle cells, and cells of the vascular system [1]. M...
Reduction in the number of D4Z4 repeats below a threshold of 10 at the 4q locus is tightly linked to Facioscapulohumeral Muscular Dystrophy (FSHD), while similar contractions at 10q locus, are not pathogenic. Sequence variations due to the presence of BlnI-sensitive repeats (10q-type) ...

The purpose of this study was to investigate how muscle oxygenation influences electromyogram (EMG) parameters during isometric and incremental exercise. In addition the study also examined the relationships among muscle oxygenation, EMG parameters and blood lactate concentration (BLa) during muscle fatigue...
