The Active Isolated Stretching (AiS) method of actively lengthening muscle tissue, and generating fascial release throughout the body. It is a type of Athletic Stretching that provides effective, dynamic treatments through self-care and facilitated stretching of major groups of muscles, but more importantly, AiS provides functional and physiological restoration of superficial and deep fascial anatomy trains. Over the past few decades, more and more experts have advocated that stretching should last up to 60 seconds. This prolonged static stretching technique was the gold standard. However, prolonged static stretching actually decreases the blood flow within the tissues, and this creates a localized ischemia and lactic acid buildup even while lengthening the muscles. 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.
The AiS Technique is Effective for Deep or Superficial Fascial Release
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 activating the reciprocal or opposing muscle contraction. This is how the isolated muscle achieves a state of optimal length and relaxation. These stretches provide maximum benefit and can be accomplished without opposing tension or resulting trauma.
Myofascial Release and Achieving Optimal Flexibility
Aaron Mattes' myofascial release technique incorporates Stretching and use of active movement and reciprocal inhibition to achieve optimal flexibility. Using a 2.0 second stretch has proven to be the key in avoiding reflexive contraction of the antagonistic muscle. Without activating muscle group contraction, restoration of full range of motion and flexibility can be successfully achieved.
