Active Isolated Stretching (AIS), developed by Aaron Mattes, is a two second stretch which allows the target muscles to optimally lengthen without triggering the protective stretch reflex and subsequent reciprocal antagonistic muscle contraction as the isolated muscle achieves a state of relaxation. These stretches provide maximum benefit and can be accomplished without opposing tension or resulting trauma. AIS is used by professional athletes and sports people to keep their muscles in top condition. I have found this stretch technique to be the best way of resolving residual old injuries and chronic stiffness.
- lengthens muscle and fascial tissue
- increases blood and oxygen flow to muscles
- restores optimal joint space
- relaxes muscles and surrounding fascia
- relieve pressure off trapped nerves
- enhance sporting performance
“Within ten days of performing the stretches, I had eliminated a rotator cuff injury that had persisted for years, as well as many other injuries since. I was amazed at how quickly these movements changed the structure and function of my shoulder.”
