However, the use of these strategies seems to be reweighted in a different way during dynamic contraction, with the recruitment of additional motor units playing a critical role in muscle force production (Sbriccoli et al.
The shift of the innervation zone (IZ), inherent to dynamic contractions, attenuates or enlarges sEMG amplitude as the IZ gets closer or farer from the electrodes (Farina et al.
2005) Muscle performance during maximal isometric and dynamic contractions is influenced by stiffness of the tendinous structures.
Results are consistent with the classical inverse relationship between torque (force) and velocity in that both PT and AVT were greatest when tested isometrically, followed by dynamic contractions at 500, 1000, 2000, and 4000 s-1 (Table 1).
Coburn et al (2005) in a similar, but more limited, investigation involving velocity (00 and 300 s-1) and contraction intensity (20%, 40%, 60%, 80%, and 100%) reported a high correlation between SEMG amplitude and force in both static and dynamic contractions.
Phase III clinical trials began last December for dynamic contractions of leg muscles associated with juvenile cerebral palsy.
In this study, comparisons were made between isometric contractions of the SW (biceps shake, triceps shake, shoulder shake, and chest shake) and traditional dynamic contractions of the same muscle for each individual lift (biceps curl, triceps extension, shoulder press, and chest press).
Dynamic contractions have been shown to correlate poorly with static contractions (Bigland-Ritchie et al.
