Hemodynamic responses to static and dynamic muscle contractions at equivalent workloads.
We tested the hypothesis that static contraction causes greater reflex cardiovascular responses than dynamic contraction at equivalent workloads [i.e., same tension-time index (TTI), holding either contraction time or peak tension constant] in chloralose-anesthetized cats. When time was held constant and tension was allowed to vary, dynamic contraction of the hindlimb muscles evoked greater inc...
متن کاملSkeletal muscle stiffness in static and dynamic contractions.
Series elastic stiffness of rat gastrocnemius medialis muscle was determined by means of sinusoidal movements (180 Hz, 0.25% of muscle length) for various contraction conditions. The effects of muscle length, activation level, velocity, prestretch, and temperature on the force-stiffness relationship were investigated. All force-stiffness curves were transformed to a linear force-alpha curve (Et...
متن کاملSTATIC AND DYNAMIC RESPONSE OF CARBON NANOTUBE-BASED NANOTWEEZERS
In this paper static and dynamic response of nanotweezers composed of two carbon nanotube (CNT) arms are investigated. Taking into account a continuum model and considering the electrostatic actuation as well as the presence of the van der Waals forces, the static nonlinear equations are solved by a step by step linearization and Galerkin projection method. Simulating the closing dynamics of a ...
متن کاملRises in whole muscle passive tension of mammalian muscle after eccentric contractions at different lengths.
This is a report of experiments carried out on the medial gastrocnemius muscle of the anesthetized cat, investigating the effects of eccentric contractions carried out at different muscle lengths on the passive and active length-tension relationships. In one series of experiments, the motor supply to the muscle was divided into three approximately equal parts; in the other, whole muscles were u...
متن کاملEquivalent Static Wind Loads for Buffeting Response
In current design practice, the dynamic wind loads are described in terms of the equivalent static wind loads based on the gust response factor. This approach results in a distribution of the equivalent static loading similar to the mean static wind load distribution, which may not always be a physically meaningful and realistic load description. In this paper, the equivalent static load repres...
