Active Isolated Stretching

The Active Isolated Stretching (AIS) method of muscle lengthening and fascial release is a type of 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.

Deep and 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 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.

Achieve Optimal Flexibility

Aaron Mattes' myofascial release technique, which also incorporates Active Isolated Stretching, uses active movement and reciprocal inhibition to achieve optimal flexibility. Using a 2 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.

Benefits of AIS

Improves flexibility

Stress relief

Reduces muscle spasm

Quickens the recovery after an injury

Promotes balance in the body

Chronic pain relief

Better posture

Relieves muscle soreness

Increases athletic performance

Reduces the risk of muscle strain and ligament sprain

Improves oxygen and nutrient delivery to cells

Stimulates lymph circulation and eliminates cellular waste

AIS is effective in alleviating the symptoms of numerous physical disorders:
