Sentence examples for maximal voluntary activation from inspiring English sources

Reproducibility of maximal quadriceps strength and its relationship to maximal voluntary activation in postpoliomyelitis syndrome.

Alterations in MVC torque (p < 0.01) and maximal voluntary activation level (p < 0.05) were comparable at termination of the two tasks.

MVC, maximal voluntary activation level, muscle compound action potential (M-wave), peak twitch and potentiated peak doublet were assessed before and immediately after each task using electrical stimulation of the femoral nerve.

Maximal voluntary activation levels of KE and PF was assessed using superimposed high-frequency (100 Hz) doublets to detect central fatigue.

Briefly, large central fatigue (i.e. reduced maximal voluntary activation) was observed after running 5 to 24 h [2], [6], [8], this activation deficit likely dependant on the muscle group tested, i.e. plantar flexors (PF) vs. knee extensors (KE) [2].

Maximal voluntary activation was significantly altered by the MUM for both muscles (Figure 4) by −19% ([95% CI: −7 to −32%], Cohen's d = 1.55) and −6% ([95% CI: 1 to −14%], Cohen's d = 0.92) for KE and PF, respectively.

The reduction in neural drive at the M speed test may also be a function of both sub-maximal voluntary activation and motor inhibition.

It is known from previous use of the twitch interpolation technique that normal individuals, with prior familiarisation and visual feedback, can reliably attain MVCs [ 32, 37, 38], so interpolated twitches were not deemed necessary here to prove maximal voluntary QF activation in normal subjects.

Additional neuromuscular characteristics (ie, maximal strength, voluntary activation and twitch properties) are presented in a companion paper.

Maximal voluntary contraction torque, voluntary activation (twitch interpolation) and peak twitch torque decreased from pre- to post-exercise (−9 ± 1, −4 ± 1 and −6 ± 1 % all trials compounded, respectively; P < 0.05), with no effect of the temperature or altitude.

On two days, eight men (21.5 ± 2.2 years, means ± SD) performed unilateral maximal isometric contractions with their knee extensors (120° knee angle) with superimposed electrical stimulation to determine maximal torque and voluntary activation for both limbs.
