Sentences with phrase «agonist activation»

The main neural adaptation underpinning the velocity - specificity effect is probably an increase in early phase agonist activation.

Such differences might be reflected in differences in agonist activation (measured by electromyography) and voluntary activation, and the sources of the differences could occur at either the spinal or cortical levels.

Like agonist activation, antagonist co-activation is generally measured using EMG amplitudes.

These cells were shown to respond in vivo to agonists of the TLR family, and this response was dependent on activation of DCs and on IL - 12 derived from the activated DCs signaling the Vα14 iNKT cells.

The lab's findings in the study, «D - serine Deficiency Attenuates the Behavioral and Cellular Effects Induced by the Hallucinogenic 5 - HT2A Receptor Agonist DOI,» suggested that D - serine - dependent NMDAR activity is involved in mediating the cellular and behavioral effects of 5 - HT2AR activation.

Ang2 has been shown to act as partial agonist of Tie2, that is, it is an antagonist of Tie2 activation in the presence of Ang1 and a weak agonist in the absence of Ang1 (ref.

Mechanism of AMPA Receptor Activation by Partial Agonists.

Due to the serious side effects caused by the activation of the pharmacologically and structurally closely related subtypes, it is essential that 5 - HT2C agonists developed for clinical use have a high specificity and subtype selectivity.

It's also effective to alternate agonist / antagonist exercises to increase motor unit activation, as long as you allow for enough rest in - between sets.

In addition to increased early phase neural drive of the agonist muscles, velocity - specific strength is likely achieved through a decrease in antagonist muscle activation (Pousson et al. 1999) and an increase in coordination (Almåsbakk & Hoff, 1996).

EMG amplitudes are often used to measure agonist muscle activation in order to:

EMG amplitudes are also used to draw inferences about agonist muscle activation.

compare the changes in the agonist muscle activation of a prime mover muscle as a result of a long - term strength training program.

Indeed, this is underscore by the fact that some carefully controlled studies have reported that substantial early phase strength gains occur in as little as 5 days without changes in agonist muscle activation as measured by EMG amplitudes (Holtermann et al. 2005).

Using the strict definition, voluntary activation refers to the percentage of involuntary force production that can be exerted by an agonist muscle group, most commonly using the interpolated twitch technique (Shield & Zhou, 2004).

Even though there are substantial problems with using EMG amplitudes to measure changes in agonist muscle activation over time, it is not uncommon for researchers to use it in this way.

This very important study is one of the very few that have actually tested the idea, by assessing the effects of just 5 days of training in untrained subjects on strength gains and on agonist, synergist, and antagonist activation levels.

In addition to increased early phase neural drive of the agonist muscles, it is possible that a greater suppression of antagonist muscle activation could contribute to increased velocity - specific strength (Pousson et al. 1999).
