muscle activation

Muscle activation refers to the process by which your brain sends signals through nerves to the muscle fibers, allowing them to contract and generate movement. When you decide to move a muscle, electrical impulses travel from the brain along the spinal cord to specific muscles. This prompts the muscle fibers to shorten and pull on bones, resulting in motion. Muscle activation is essential for all physical activities, from simple movements like walking to complex exercises. Understanding this process can help in training, rehabilitation, and improving overall physical fitness.
