The AIS Technique: Deep, Superficial Fascial Release

​

Active Isolated Stretching (AIS) is one of the methods of stretching most used by today's athletes, massage therapists, personal/athletic trainers, and professionals. Active Isolated Stretching allows the body to repair itself and also to prepare for daily activity. The Active Isolated Stretching technique involves the method of holding each stretch for only two seconds. This method of stretching is also known to work with the body's natural physiological makeup to improve circulation and increase the elasticity of muscle joints and fascia. 

​

The Active Isolated Stretching (AIS) method of muscle lengthening and fascial release is a type of Athletic Stretching Technique that provides effective, dynamic, facilitated stretching of major muscle groups, but more importantly, AIS provides functional and physiological restoration of superficial and deep fascial planes. Over the past few decades many experts have advocated that stretching should last up to 60 seconds. For years, this prolonged static stretching technique was the gold standard. However, prolonged static stretching actually decreases the blood flow within the tissue creating localized ischemia and lactic acid buildup. This can potentially cause irritation or injury of local muscular, tendinous, lymphatic, as well as neural tissues, similar to the effects and consequences of trauma and overuse syndromes.

​

Performing an Active Isolated Stretch of no longer than two seconds 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.
