Voluntary Contraction: How it Works

What happens when you want to contract a muscle?

The nervous system is a control system of the body and is a bit like a computer.  The brain is similar to the software and is responsible for making decisions and the nerves are like the hardware or wiring that communicates those decisions with the rest of the body.

Voluntary skeletal muscles contractions occur as a result of conscious effort originating in the brain.

The brain sends small electrochemical impulses or action potential through the central nervous system (brain & spinal cord) and the peripheral nervous system.

Reaching and activating the motor neuron that innervates several muscle fibers leading to a muscle contraction.

STIMFIT Ab-Belt: How it Works

The STIMFIT abdominal belt replace the central nervous system by generating electrical impulses.

The impulses are generated by the STIMFIT power pod and delivered through electrodes on the skin in direct proximity to the muscles to be stimulated. The impulses mimic the action potential coming from the central nervous system, causing the muscles to contract.

STIMFIT Ab-Belt: Targeted Muscles

Due to its unique design and the use of very large electrodes, the STIMFIT ab-belt can reach the Rectus Abdominis and External Oblique abdominal muscles as well as the deep Internal Oblique and Transverse Abdominis muscles.
