Compex Muscle Stimulator Program Descriptions

Note: * found on Performance and Sport elite models
       ** found only on Sport Elite model

Here is what the various programs are designed to do:

Pre-Warm Up*

Increases blood flow to the muscle which increases the temperature of the muscle. All the reactions associated with a muscular contraction will occur at a faster rate. The muscle will more easily change shape. Neural inhibition is decreased so that more muscle fibers can be recruited when the muscle contracts. Oxygen is released to the muscle at an increased rate.


A short program that puts minimal load on the muscle while speeding the reaction time of a muscular contraction. This program should be used 10 minutes prior to a workout or competition.

Explosive Strength**

Stimulates the fast twitch Type IIb muscle fiber and trains Type IIb creatine phosphate energy delivery system. This energy delivery system provides stored energy needed for the first three to five seconds of work while the multi-enzyme mediated anaerobic and aerobic energy delivery systems proceed.


This program trains the Type IIb fast twitch muscle fibers. It trains these muscle fibers to deliver energy anaerobically and generate a great deal of force for efforts lasting up to one minute. This is done without cardiovascular or mental fatigue. There is no risk of injury often associated with intense muscular contractions of this kind.


This program trains the Type IIa fast twitch muscle fibers. This is the most common muscle fiber type in an average individual. These fibers can deliver energy both aerobically and anaerobically. They are well adapted for delivering energy at a rate fast enough to support very hard efforts that last for 1 to 5 minutes.


This program stimulates the Type I slow twitch muscle fibers. These fibers are capable of delivering energy aerobically and therefore are the most used muscle fiber for efforts lasting many minutes to many hours.

Active Recovery

This program has three parts to it. The first part with its rapid contractions at 9Hz, 8 Hz and 7Hz squeezes the blood out of the capillary beds, flushes out the waste products from the work done, and makes room for fresh blood to supply the muscle with the oxygen and nutrients it needs to recover. The second part of the program, with contractions occurring at 6 Hz, 5 Hz, and 4Hz, stimulates the production of endorphins for an analgesic response. The third part of the program relaxes the muscle with contractions at 3 Hz, 2 Hz, and 1 Hz.

Recovery Plus**

This program has both the flush and endorphin productions parts found in the Active Recovery program. There is a greater emphasis on the endorphin production however. This program was written to meet the recovery needs of those involved in very hard efforts day after day.


This program is dedicated to relaxing the muscle. Ischemic or knotted muscles will relax to allow better blood flow to the muscle, and sore muscles are relieved.
