Isometric Contraction of Epidermis and Stratum Corneum With Heating [PDF]

Journal of Investigative Dermatology, 1970
Isometric contraction studies provide valuable data on the response of epidermal tissue to heating in water. A major change occurring in the tissue during heating is a conversion of the molecular structure of the α-filaments to β-configuration. Prior treatment of the tissue with several solvents show specific effects on the isometric contraction ...

Are the antagonist muscle fatigued during a prolonged isometric fatiguing elbow flexion at very low forces for young adults?

Frontiers in Physiology, 2022
The aim of this study was to examine whether antagonist muscles may be fatigued during a prolonged isometric fatiguing elbow flexion at very low forces.

Insights From Computational Modeling Into the Contribution of Mechano-Calcium Feedback on the Cardiac End-Systolic Force-Length Relationship

Frontiers in Physiology, 2020
In experimental studies on cardiac tissue, the end-systolic force-length relation (ESFLR) has been shown to depend on the mode of contraction: isometric or isotonic.

Effect of hip adduction/abduction contraction on pelvic floor in young healthy women

Journal of Physical Fitness and Sports Medicine, 2022
Pelvic floor muscle training has been reported to be effective in preventing and improving urinary incontinence. Patients must learn to perform pelvic floor muscle contractions without pushing down the pelvic floor by contracting other muscle groups ...

Influence of Joint Angle on Residual Force Enhancement in Human Plantar Flexors

Frontiers in Physiology, 2017
Compared to pure isometric contractions, isometric muscle force at a given length is larger when the eccentric contraction is conducted before the isometric contraction.

Extrapolation of time series of EMG power spectrum parameters in isometric endurance tests of trunk extensor muscles [PDF]

, 1998
The aim of the present study was to test the viability of using short isometric contractions of trunk extensor muscles to perform an assessment of their endurance capacity. To this aim two types of analysis were performed.

Perceived force in fatiguing isometric contractions [PDF]

Perception & Psychophysics, 1983
An integrative approach emphasizing both psychological and physiological components in force perception has started to emerge in motor psychophysics. In this experiment, the relation between isometric force (produced by the elbow flexors~ and perceived force was examined over a range of forces maintained until maximal endurance.

Preliminary study of muscle contraction assessment by NIR spectroscopy [PDF]

, 1998
NIR spectroscopy allows monitoring of muscle oxygenation and perfusion during contraction. The knowledge of modifications of blood characteristics in body tissues has relevant clinical interest. A compact and reliable device, which makes use of two laser

Regional Differences in Biceps Femoris Long Head Stiffness during Isometric Knee Flexion

Journal of Functional Morphology and Kinesiology, 2021
This study sought to investigate whether the stiffness of the biceps femoris long head differs between proximal and distal regions during isometric knee flexion at different contraction intensities and muscle lengths. Twelve healthy individuals performed
