Muscle Electromyography Analysis

Satisfactory Essays
A muscle is composed of multiple individual muscle fibers that are organized in a motor unit that is innervated by a single motor neuron. The motor neuron is responsible for propagating an action potential resulting in the muscle fibers in the motor unit contracting. An electromyography (EMG) is able to detect the depolarization of the muscle fibers, characterizing an action potential, and help quantify the number of active fibers and the magnitude of force. We hypothesize that the triceps will be activated more for movements involving supination with and without elbow extension than during reverse and regular curls as indicated by values from the EMG. We tested the hypothesis by connecting two surface-level electrodes to the triceps and
