Studies are now finding that the use of foam rollers may play an important part in the recovery of muscle soreness after daily exercise as well as the healing process necessary from severe injuries. By massaging the muscles, foam rollers increase both blood flow and oxygen to tissue, speeding up the healing process. They can help lengthen and strengthen stiff tight muscles resulting in an increased range of motion preventing injuries. Careful, controlled use of foam rollers can be a great aid in breaking up underlying scar tissue and adhesions in skin and muscles. It can also be a great tool for someone who spends most of their day sitting in an office. It can relieve the soreness from inactivity. Foam rollers improve athletic performance by increasing flexibility as well as reducing muscle soreness by slashing recovery time. Two studies, one reported in the Journal of Sports Rehabilitation determined that foam rolling in combination with static stretching after exercise increased range of motion in hips. The other at Central Michigan University showed that rollers made muscles less resistant to motion by increasing flexibility with as little as 90 second intervals on sore areas. All the studies seem to agree on the fact that the use of foam rollers appears to stimulate pressure receptors beneath the skin and relax the central nervous system. Whether you are extremely active or have an occupation that involves a great deal of sitting, it may be useful to incorporate foam roller exercises into your daily regimen.
