Experiment Data: 010/03/12 page 3 Post-lab Quiz Results You have not completed the Post-lab Quiz. 010/03/12 page 4 Review Sheet Results 1. What is the difference between stimulus intensity and stimulus frequency? Your answer: Stimulus intensity: is the amount of force that is generated to cause the stimulus. the more force will increase the stimulus intensity. Stimulus frequency: is the measured frequency and the amount of stimulus to a muscle that has occurred in "x" amount of time. 2. In this experiment you observed the effect of stimulating the isolated skeletal muscle multiple times in a short period with complete relaxation between the stimuli. Describe the force of contraction with each subsequent stimulus. Are these resultscomplete relaxation between the stimuli....
