Active Isolated Stretching
Active Isolated Stretching (AIS) is a method of stretching developed by Aaron Mattes,
kinesiotherapist and massage therapist. This method is widely used by physical
therapists, athletic trainers and athletes to achieve optimal flexibility and range of motion,
and is a great tool for maintaining movement and structural balance after receiving
Myofascial Integration work.
This method of fascial release provides effective dynamic facilitated stretch of major
muscle groups, but more importantly functional and physiological restoration of superficial
and deep fascial planes.
Performing and active isolated stretch of no longer than 2.0 seconds allows the target
muscle to optimally lengthen without triggering the protective stretch reflex and
subsequent reciprocal antagonistic muscle contraction. As the isolated muscle achieves a
state of relaxation, maximal beneficial stretch can be accomplished without opposing
tension or resulting trauma.
