Gated 31P-nuclear magnetic resonance followed the metabolic fluctuation in rat gastrocnemius muscle during a contraction cycle. Within 16 ms after stimulation, the phosphocreatine (PCr) level drops 11.3% from its reference state. The PCr minimum corresponds closely to the time of maximum force contraction. Pi increases stoichiometrically, while ATP remains(More)
As e-learning environments become a standard form of instruction more learners are forced to view video examples as a substitute for interactive classroom learning. These non-interactive multimedia environment that use auditory narration to improve learning have been referred to as a vicarious learning environment (See Gholson & Craig, 2006 for review).(More)
