## Indications for use
The Compex® Sport Plus is intended to stimulate healthy muscles in order to improve or facilitate muscle performance. The Compex® Sport Plus is not intended to be used in conjunction with therapy or treatment of medical diseases or medical conditions of any kind. None of the Compex® Sport Plus training programs is designed for injured or ailing muscles and its use on such muscles is contraindicated. The Compex® Sport Plus electrical impulses allow the triggering of action potentials on motoneurones of motor nerves (excitations). These excitations of motoneurones are transmitted to the muscle fibers via the motor endplate where they generate mechanical muscle fiber responses that correspond to muscle work. Depending on the parameters of the electrical impulses (pulse frequency, duration of contraction, duration of rest, total session duration), different types of muscle work can be imposed on the stimulated muscles. The various types of muscle work that the Compex® Sport Plus can impose on the stimulated muscles are able to improve or facilitate muscle performance. The Compex® Sport Plus may therefore be considered a technique of muscle training.
