Foam rolling is a self-myofascial release (SMR) stretching technique that has been embraced throughout the fitness industry. This effective and simple to do technique delivers positive, feel good results. Foam rollers have become easily accessible, either shared at the gym or found in almost any sporting goods aisle to bring home for a minimal investment. Using the foam roller can deliver improvements in flexibility, muscle recovery, movement efficiency, inhibiting overactive muscles, and pain reduction with just minutes of application

Why SMR?

SMR can be done with a variety of tools beyond foam rollers, such as medicine balls, handheld rollers or other assistive devices. Foam rollers vary in density, surface structure, and even temperature modifications. Whatever the tool or variation selected, SMR focuses on the neural and fascial systems in the body that can be negatively influenced by poor posture, repetitive motions, or dysfunctional movements (1). These mechanically stressful actions are recognized as an injury by the body, initiating a repair process called the Cumulative Injury Cycle (Figure 1) (1). This cycle follows a path of inflammation, muscle spasm, and the development of soft tissue adhesions that can lead to altered neuromuscular control and muscle imbalance (1-4). The adhesions reduce the elasticity of the soft tissues and can eventually cause a permanent change in the soft tissue structure, referred to as Davis’s Law. SMR focuses on alleviating these adhesions (also known as “trigger points” or “knots”) to restore optimal muscle motion and function (1,5).

SMR is based on the principal of autogenic inhibition. Skeletal muscle tissue contains muscle spindles and Golgi tendon organs (GTO), two neural receptors. Muscle spindles are sensory receptors running parallel to muscle fibers, sensitive to a change and rate of muscle lengthening. When stimulated, they will cause a myotatic stretch reflex that causes the muscle to contract. The GTO receptors, located in the musculotendinous junctions, are stimulated by a change and rate of tension, and when they are stimulated will cause the muscle to relax (2). When a change in tension is sustained at an adequate intensity and duration, muscle spindle activity is inhibited causing a decrease in trigger point activity, accompanied by a reduction of pain (1,6-7). In simpler terms, when the pressure of the body against the foam roller is sustained on the trigger point, the GTO will “turn off” the muscle spindle activity allowing the muscle fibers to stretch, unknot, and realign (5).

Autogenic Inhibition: The process by which neural impulses that sense tension are greater than the impulses that cause muscles to contract, providing an inhibitory effect to the muscle spindles.

The Benefits of SMR

SMR benefits include:

  • Correction of muscle imbalances
  • Muscle relaxation (1,2)
  • Improved joint range of motion
  • Improved neuromuscular efficiency (1,3,4)
  • Reduced soreness and improved tissue recovery (1)
  • Suppression/reduction of trigger point sensitivity and pain (2,6,7)
  • Decreased neuromuscular hypertonicity (1)
  • Provide optimal length-tension relationships
  • Decrease the overall effects of stress on the human movement system (1)

Guidelines to Start Rolling

Foam rolling should be done before static or dynamic stretching activities, improving the tissue’s ability to lengthen during stretching activities. Foam rolling can also be done as part of the cool-down (1-2). Foam rolling activities should be performed on tissues identified as overactive during the assessment process.

Most clients can enjoy foam rolling on their own once they’ve been instructed on how to properly perform the exercises. Foam rolling is not appropriate for all clients, including those with congestive heart failure, kidney failure, or any organ failure, bleeding disorders, or contagious skin conditions. If clients have medical issues, have them seek the advice of their medical professional before starting SMR or foam rolling activities (1).
