Vascular muscle series elastic element stiffness during isometric contraction.
Series elastic element stiffness was studied during isometric muscle contraction in cylindrical segments of dog common carotid artery. These vessel segments were mounted in vitro and restored to in situ length. Vessel diameter was constantly monitored with a linear displacement transducer. The arteries were subjected to isometric contraction by adding norepinephrine to the bath and elevating th...
متن کاملSite of increased vascular resistance during isometric muscle contraction.
GRAY, SARAH D., ERIK CARLSSON, AND NORMAN C. STAUB. Site of increased vascular resistance during isometric muscle contraction. Am. J. Physiol. 213(3): 683-689. 1967.-We studied the intramuscular vessels during maximal tetanic contraction to localize the site of increased flow resistance. We examined the microcirculation of rats whose calf muscles were rapidly frozen before, during, or after max...
متن کاملFinite element model of intramuscular pressure during isometric contraction of skeletal muscle.
The measurement of in vivo intramuscular pressure (IMP) has recently become practical and IMP appears well correlated with muscle tension. A numerical model of skeletal muscle was developed to examine the mechanisms producing IMP. Unipennate muscle is modelled as a two-dimensional material continuum that is incompressible and nonlinearly anisotropic. The finite element technique is used to calc...
متن کاملHip Muscle Activity during Isometric Contraction of Hip Abduction
[Purpose] This study aimed to determine the effect of varying hip flexion angle on hip muscle activity during isometric contraction in abduction. [Subjects] Twenty-seven healthy men (mean age=21.5 years, SD=1.2) participated in this study. [Methods] Surface electromyography (EMG) was recorded of the upper portion of the gluteus maximus (UGM), lower portion of the gluteus maximus (LGM), tensor f...
متن کاملDetecting Localised Muscle Fatigue during Isometric Contraction using Genetic Programming
We propose the use of Genetic Programming (GP) to generate new features to predict localised muscles fatigue from pre-filtered surface EMG signals. In a training phase, GP evolves programs with multiple components. One component analyses statistical features extracted from EMG to divide the signals into blocks. The blocks’ labels are decided based on the number of zero crossings. These blocks a...
