Gender differences in cardiovascular response to upper extremities isometric exercise in normotensive young subjects

open access: yesNational Journal of Physiology, Pharmacy and Pharmacology, 2021
Background: Isometric exercises are a part of our activities and many occupational task. Isometric exercises produce a characteristic increase in blood pressure (BP).

Perceived force in fatiguing isometric contractions [PDF]

open access: yesPerception & 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.

Localized Electrical Impedance Myography of the Biceps Brachii Muscle during Different Levels of Isometric Contraction and Fatigue

open access: yesSensors, 2016
This study assessed changes in electrical impedance myography (EIM) at different levels of isometric muscle contraction as well as during exhaustive exercise at 60% maximum voluntary contraction (MVC) until task failure.

Residual force enhancement due to active muscle lengthening allows similar reductions in neuromuscular activation during position- and force-control tasks

open access: yesJournal of Sport and Health Science, 2020
Background: Residual torque enhancement (rTE) is the increase in torque observed during the isometric steady state following active muscle lengthening when compared with a fixed-end isometric contraction at the same muscle length and level of ...
