Created and developed by Aaron L. Mattes, Active Isolated Stretching (AIS) is a stretch technique that focuses on isolating individual muscles and/or muscle groups and then actively stretching them for a time period of between 1 ½ – 2 seconds with a 1lb to 1lb ½ of additional pressure applied to them. In this manner the targeted area is properly elongated, increasing flexibility and range of motion to an area of the body without bringing in concern for a muscle’s “stretch reflex” engaging and shutting the muscle down causing it to contract, thereby avoiding the possibility of any tearing known as a strain/sprain.
This form of stretching promotes the transportation of blood, oxygen, and lymph to the area and can assist in stimulating neurological connections as well. These stretches have been shown to improve almost any physical condition including function with muscle injuries, diseases and strokes. AIS is beneficial in restoring proper posture and regaining stamina for any part of one’s life, whether it is in the office, the home for athletic training or an athletic event. For adult and/or child athletes this type of therapy can be a key beneficial element added to improve performance when applied pre and post event.
