6 Benefits to Using A Foam Roller | Fitness Resources
Foam rollers are an effective method of reducing tension and increasing muscle length for either a pre-workout warm-up or post-exercise active recovery. Technically known as self-myofascial release (SMR), the use of foam rollers for the purpose of reducing muscle tension has become a widely accepted fitness practice. There are two prevailing theories regarding why foam rolling works: Foam rolling creates length change based on the principle of autogenic inhibition, which involves the sensory receptors of the Golgi tendon organ (GTO) and muscle spindle. The GTO senses tension placed on a muscle, while the spindle identifies length change and the rate of change within a particular muscle. Autogenic inhibition is the response that occurs when a muscle is placed under tension and the GTO sends a signal to the spindles to allow the muscle to lengthen. The pressure of the foam roller on the muscle increases tension on the muscle fibers, signaling the GTO to allow the muscle spindles and
