We also present reference regression Lab Report Instructions for Lab 4 (Grip Strength & EMG Activity)-1. recorded electric activity should remain constant. The labor force participation rate continues to fall. A combination of the two, the amplitude of the EMG signal and force of contraction increases because a finite number of fibers are firing more often, once this is over, more fibers need to be recruited to fire.
