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. 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. Aaron Mattes has developed this method of proper athletic stretching over the past 40+ years, working with thousands of patients, doctors, and health professionals.
