Questions 1. Plot the absolute integral of muscle contraction as a function of the absolute integral of the EMG signals for each muscle clinch. 2. Is there a linear relationship between the absolute integral under EMG signals and the absolute integral under the muscle contraction? 3. Do muscle fibers have a refractory period like nerve fibers? 4. Does the amplitude of the EMG signal and the force of contraction, as measured by the absolute integrals, increase because a finite number of fibers are firing more often, or because more fibers are recruited to fire as the intensity of signals in the motor neurons increases, or a combination of these two?
