Action Potential (Electrical Activity) follow which principle
Archimedes'
all-or-none
non-contradiction
Simplicity
Muscle contraction take place when:
when membrane excitation occurs.
when Ca2+ ions is released.
when actin and myosin filaments form cross-bridges.
when the sarcoplasmic reticulum accepts Ca2+ ions.
EMG should be synchronised with ____________ and ___________ to provide dynamic analysis of muscles and joint position, speed and acceleration.
(a)
Rectifying EMG signals means:
(a)
Identify which of the statement/s is/are correct as a conclusion one can get from sEMG studies without the use of additional software?
the amount of muscle force production.
timing of excitation of muscles.
mechanisms of force production.
if signals are properly normalized (as a % of MVC), we can infer relative muscle excitation within-subject and between-muscles.
