Why is size principle reversed during electrical stimulation? For many years it has been believed that the use of electromyostimulation (EMS) to stimulate muscle contraction creates a reversal of the general size principle recruitment order, due to the larger motor unit axons having a lower resistance to electric current.
What is the correct order of muscle recruitment according to the size principle? The size principle states that motor units will be recruited in order of size from smallest to largest depending upon the intensity. When considering the various properties of the motor units this makes sense. The small units don’t produce much force, they are slow to act, and they are resistant to fatigue.
What is the effect of the size of the motor unit on its strength of its contraction? Starting with the smallest motor units, progressively larger units are recruited with increasing strength of muscle contraction. The result is an orderly addition of sequentially larger and stronger motor units resulting in a smooth increase in muscle strength.
Why are small motor units recruited first? As a general rule, motor units are recruited in order of their size. When the muscle is activated initially, the first motor units to fire are small in size and weak in the degree of tension they can generate. … There are exceptions to the size-ordered activation of motor units.

Where do the charges that cause static electricity come from?
Most of the time positive and negative charges are balanced in an object, which makes that object neutral. Static electricity is the result of an imbalance between negative and positive charges in an object. These charges can build up on the surface of an object until they find a way to be released or discharged.
