Do differences in levels, types, and duration of muscle contraction have an effect on the degree of post-exercise depression?

Frontiers in Human Neuroscience, 2016
We conducted two experiments to determine how differences in muscle contraction levels, muscle contraction types, and movement duration affect degree of post-exercise depression (PED) after non-exhaustive, repetitive finger movement.

Biointegrated Multilayer Stretchable OLED Platform With Strain‐Decoupled Architecture for Durable Phototherapeutic Applications

Advanced Science, EarlyView.
A multilayer stretchable organic light‐emitting diode (SOLED) patch enables conformal, high‐fill‐factor phototherapeutic illumination through vertically decoupled electrodes and robust encapsulation. The textile‐based SOLED platform delivers stable skin‐contact red light for wearable phototherapy and 5‐aminolevulinic acid (ALA)‐mediated photodynamic ...

Impact of contraction intensity and ankle joint angle on calf muscle fascicle length and pennation angle during isometric and dynamic contractions

Scientific Reports
During muscle contraction, not only are the fascicles shortening but also the pennation angle changes, which leads to a faster contraction of the muscle than of its fascicles. This phenomenon is called muscle gearing, and it has a direct influence on the

The influence of residual force enhancement on spinal and supraspinal excitability [PDF]

PeerJ, 2018
Background Following active muscle lengthening, there is an increase in steady-state isometric force as compared with a purely isometric contraction at the same muscle length and level of activation.

The functional form of the lognormal distribution as a sum of decaying exponential and sinusoidal terms applied to the isometric pinch force of human fingers [PDF]

, 2006
The transient data of the pinch force produced between the human forefinger and thumb have been shown to fit the functional form of the well-known lognormal density function.

Finite element analysis of feeding in red and gray squirrels (Sciurus vulgaris and Sciurus carolinensis)

The Anatomical Record, EarlyView.
Abstract Invasive gray squirrels (Sciurus carolinensis) have replaced the native red squirrel (Sciurus vulgaris) across much of Great Britain over the last century. Several factors have been proposed to underlie this replacement, but here we investigated the potential for dietary competition in which gray squirrels have better feeding performance than ...

Comments on the thermodynamical background to the growth and remodelling theory applied to a model of muscle fibre contraction

Applied and Computational Mechanics, 2010
Muscle fibre contraction is a complex thermomechanical process. The change in muscle fibre length (isotonic contraction) and tension (isometric contraction) may be regarded as muscle fibre growth (change in length) and remodelling (change in stiffness ...

Effect of Knee Angle, Contractile Activity, and Intensity of Force Production on Vastus Lateralis Stiffness: A Supersonic Shear Wave Elastography Pilot Study

Sports
Supersonic shear image (SSI) ultrasound elastography provides a quantitative assessment of tissue stiffness using the velocity of shear waves. SSI’s great potential has allowed researchers in fields like biomechanics and muscle physiology to study the ...

Translation of the Tibia During Isometric Contraction of the Quadriceps [PDF]

, 1983
The purpose of this study was to determine in normal knees, and in knees with anterior cruciate ligament absence, what effect maximal voluntary isometric contraction of the quadriceps has on translation of the tibia on the femur.
