The more we practice, the more insulation (myelin sheath) builds along our neural pathways to create a springing foward of new patterns. When we do our movements, we are giving the body input that it needs to “practice” that reflex or patterns for cells to communicate. Repetition is vital so that a person not only has the neural pathway for it, but the protective myelin sheath to keep it strong. I recently stumbled upon this Ted Talk by Annie Bosler and Don Greene that gives a perfect explanation on the importance of practice and repetitive motion. Check it out!
