How Muscles Are Built Naturally, the brain uses electrical messages to tell muscles what do. For example, when we walk, the brain naturally would instruct the muscles to contract via the nerves, producing movement. This process of ‘contraction’ is what makes the leg move, which happens only for a short time, then the muscles relax again. Strength is built by placing the targeted muscle groups under repeated movement with resistance, which would incur damaged muscle tissues. The body would then repair or replace these damaged muscle fibers through a cellular process where it fuses muscle fibers together to form new muscle protein strands or myofibrils. These repaired myofibrils increase in thickness and number to create muscle hypertrophy (growth).
Besides muscle growth, the muscle contraction causes a squeezing action to happen on the veins, pushing blood back to the heart, boosting circulation. The medical benefits of a good circulation include slowing muscle-wasting making muscles stronger and increasing flexibility (range of motion).
EMS and Its Role In Muscle Building
EMS mimics the entire muscle building process naturally by delivering electrical pulses to the body which activate motor nerves in the body, which in turn cause muscles to contract. With EMS, the intensity and frequency of these pulses can be controlled and delivered in different phases of the training, enhancing muscle building in the process.
