There are a lot of research for importance and effect of nervous system functional on capacity of skeletal muscles that results are useful for rehabilitation of muscle disabilities, increasemass of muscle fibers and myofibrils, increase of muscle speed and resistance, improve of contractile power and motor units synchronization.
To bying in to nerve and nervous impulses in muscle fibers, thier function will be improved, but denervation is to cause of some biochemical changes in muscle fibers.
After denervation muscle atrophy will be appear. Strength training affect to the muscle mass and increase the power of muscles that related to the hormonal and chemical effects and improved in nervous system ability.
Resent approach shows that muscle hypertrophy not only related to the strength training but to the neural effect and to the motor unit action, and there are a direct relationship between these two factors, when the strength is in the highest level the action of motor units and nervous system is in high, and with decrease in strength the motor unit action will be in lowest level.
