The elevated pressure response can be explained by the actual mechanical pressure of the muscles acting on the blood vessels and the pressor reflex that occurs during static contraction
. In addition, the elevated intrathoracic and intraabdominal pressures that occur during the Valsalva maneuver can cause a more dramatic increase in blood pressure (9).
Subsequently, subjects performed a static contraction
, where they were asked to maintain a force level of 10% MVC during isometric dorsiflexion for two minutes.
Intramuscular pressure, EMG and blood flow during low-level prolonged static contraction
Several studies investigated the effect of poststroke impairments on muscle architecture as measured by ultrasound during static contraction
Further, all literatures presented above were analyzed with EMG signal recorded from the biceps brachii during a static contraction
. A non-linear relationship with muscle force of MDF and MNF are also investigated in a dynamic contraction  and in a large muscle .
Lie on your back and produce a static contraction
by performing a head-nodding motion, bringing your chin toward your throat.
* Limit load levels (muscle activity) to 15% MVC or below (Maximum Voluntary Contraction [MVC] is the maximum force a muscle can voluntarily generate during a static contraction
. For any given task, the higher the %MVC, the greater the risk of fatigue and/or injury.).
The muscles and tendons of both forearms, the elbow joints, wrists and hands are set in a medium to firm static contraction
, depending on amount of recoil.
Any static contraction
of a muscle--say holding your arm away from your side--halts circulation, thus depriving that area of the body from receiving oxygen and ridding itself of waste products such as lactic acid and carbon dioxide.
The narrow central peak in the cumulant density function and the coherence dominantly in the alpha and beta bands are similar to what has been observed in numerous studies during static contraction
in healthy adults previously [31, 47, 49].
Accordingly, the purpose of the present study was to investigate the physiological responses to a static contraction
in the standing position and the supine position.
Comparison between the effect of static contraction
and tendon stretch on the discharge of group III and IV muscle afferents.
