Fall in the firing rate of muscle spindles during stretching

Neuroscience and Behavioral Physiology, 1981
Investigation of the dynamic responses of 500 muscle receptors to stretching of the triceps surae muscle of the de-efferented hind limb of anesthetized cats revealed in 23 cases a transient fall in the firing rate (FFR) of muscle spindle receptors while muscle stretching was in progress.

Strain-rate Dependency of Axonal Tolerance for Uniaxial Stretching

SAE Technical Paper Series, 2017
This study aims to clarify the relation between axonal deformation and the onset of axonal injury. Firstly, to examine the influence of strain rate on the threshold for axonal injury, cultured neurons were subjected to 12 types of stretching (strains were 0.10, 0.15, and 0.20 and strain rates were 10, 30, 50, and 70 s-1).

Effect of Stretch Frequency and Sex on the Rate of Gain and Rate of Loss in Muscle Flexibility During a Hamstring-Stretching Program

Journal of Strength and Conditioning Research, 2012
This study evaluated the effects of 4 different weekly stretching protocols on the rate of gain and decline in hamstring flexibility over an 8-week period, across sex. Using a randomized single-blind design, 53 healthy subjects aged 18-46 years were assigned to 1 of 4 stretching protocols or a control group. The stretching protocols consisted of either

Stretching rates in discrete dynamical systems

Chaos, Solitons & Fractals, 2000
The asymptotic behaviour of trajectories in nonlinear dynamical systems in \(\mathbb{R}^n\) (for \(t\to\infty)\) can be characterized by stretching and/or shrinking rates of volume elements in different directions. Fixed points, cycles, tori and chaotic attractors are different types of attractors, which are distinguishable by their Lyapunov exponents ...

Stretch effect on the vaporization rate in Fendell’s problem

Combustion and Flame, 2000
Abstract An analytical solution of Fendell’s problem is obtained taking into account the dependencies of density and molecular diffusivities on temperature for infinitely fast chemistry. Also, the equilibrium Clayperon-Clausius condition has been used for conditions at the surface of the liquid instead of the commonly used, and inconsistent ...

Recruitment, Rate Modulation and the Tonic Stretch Reflex

1976
Publisher Summary To solve the problems concerning the gradation of muscle activation, it is important to know which mechanisms might be responsible for the amount of rate modulation that occurs within the range of variable and incomplete recruitment of a motoneurone pool.

Effects of Stretching Exercise on Heart Rate Variability During Pregnancy

Journal of Cardiovascular Nursing, 2017
Background: Little evidence exists for effects of low-intensity exercises such as stretching on cardiovascular health in pregnant women. Aim: Our aim was to evaluate the effect of a 20-minute stretching exercise on heart rate variability (HRV), blood pressure (BP), and heart rate ...

Stretching Rate of Passive Lines in Turbulence

2005
The temporal evolution of passive lines in turbulence of an incompressible viscous fluid is simulated numerically for the Taylor-length Reynolds umber up to 252. The passive lines elongate in average exponentially in time. The mean exponential stretching rate γ obeys the Kolmogorov scaling law, i.e.

Effect of stretching the superior vena cava on heart rate in rats

American Journal of Physiology-Heart and Circulatory Physiology, 1981
The effect on the heart rate of stretching the superior vena cava 3-4 mm above its entrance to the right atrium was examined in rats anesthetized with chloralose. The superior vena cava was stretched 41 times in 16 rats. There was a mean increase of 24.1 +/- 1.9 (SE) beats/min.
