A study was made of the influence of glycerol loading on contraction responses of the m. sartorius upon stimulation in normal and calcium-free Reinger solutions by caffeine, tetanic electrostimulation and single electric impulses. It was determined that in the glycerol medium each type of stimulation caused contractility potentiation. Ca2+-ions proved to block the responses of potentiation. The data suggest that there should be a potentiation mechanism common to each type of stimulation.
