Muscle Excitability: Stimulation Experiment

This lecture focuses on conducting a muscle stimulation experiment to observe contractions by placing electrodes on the muscle, gradually increasing the stimulation current, and analyzing the recruitment of muscle units. The instructor demonstrates the importance of maintaining the skin around the muscle for proper functioning and explains the process of achieving supramaximal stimulation. The lecture also covers the analysis of muscle contractions, including the impact of removing undersampling on force irregularities. The goal is to understand muscle excitability through practical experimentation and data analysis.
