RISA Comparison of the Mechanical Behavior of the Cat Soleus Muscle With a Distribution-Moment Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A state-variable model for skeletal muscle, termed the “Distribution-Moment Model,” is derived from A. F. Huxley’s 1957 model of molecular contraction dynamics. The state variables are the muscle ...
The Variation of Isometric Energy Rates With Muscle Length: A Distribution-Moment Model Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The Distribution-Moment Model of skeletal muscle, which has been enhanced recently to make possible the calculation of chemical energy release (Ė) and heat production (Ḣ) rates [1], is applied ...
A Re-examination of Calcium Activation in the Huxley Cross-Bridge Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper investigates mathematical relations between models of calcium activation kinetics and Huxley-type models of cross-bridge dynamics in muscle. It is found that different calcium-activation ...
A Programmable Limb Testing System (and Some Measurements of Intrinsic Muscular and Reflex-Mediated Stiffnesses)
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new versatile apparatus for investigating the neuromusculoskeletal dynamics of the upper limb, termed the Programmable Limb Testing System (PLTS) has been designed, built, and tested. The ...
A Quantitative Evaluation of the Frequency-Response Characteristics of Active Human Skeletal Muscle In Vivo
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes an investigation of the frequency-response characteristics of active human skeletal muscle in vivo over the frequency range 1 Hz to 15 Hz. The applied force, forearm position, ...
Predictions of the Existence, Frequency, and Amplitude of Physiological Tremor in Normal Man Based on Measured Frequency-Response Characteristics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Mathematical models for 1) musculoskeletal dynamics, and 2) reflex feedback, based on the results of the authors’ frequeny-response measurements on normal adult male human subjects, are combined ...
Extensional Recovery of an Intact Erythrocyte From a Tank-Treading Motion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Normal human erythrocytes suspended in shear flow are stretched into quasi ellipsoidal forms while their membranes rotate smoothly (tank-treading). Following abrupt cessation of shear the cells ...
The Effects of Cross-Fiber Deformation on Axial Fiber Stress in Myocardium
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We incorporated a three-dimensional generalization of the Huxley cross-bridge theory in a finite element model of ventricular mechanics to examine the effect of nonaxial deformations on active ...
Determination of Cellular Mechanical Properties by Cell Poking, With an Application to Leukocytes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper we review the cell-poking technique as an approach for investigating the mechanical properties of living cells. We first summarize the rationale for the technique and the mainly ...
Partially Activated Human Skeletal Muscle: An Experimental Investigation of Force, Velocity, and EMG
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experiments are described which establish quantitative relations between muscular force, contraction velocity, and the electrical activity of the muscle (as measured by the surface EMG) under ...
