Massage therapy involves manipulation of the soft tissues in the body, which include the muscles, tendons, skin and connective tissues, all of which support and control muscle movement report researchers at the Patient Education Institute of the National Institutes of Health. The NIH reports that there is evidence that massage can successfully treat muscles that make up more than half the body's weight.
Reduce Stiffness
Massage reduces stiffness because of the pressure that's applied to the connective tissues and the muscles. The pressure applied to the muscles and adjoining tendons stretches the tissues resulting in relaxed muscles that move freely. Heat that's used in a variety of massage techniques also can help alleviate muscle stiffness. Deep tissue massage requires the therapist to work along and against the grain of the muscle to break up knots and tension.
Circulation
Circulation of blood and lymph is increased with massage, helping with healing and restoring muscles to their healthiest state. Lymph is the substance stored in the body that carries waste out of the body. The increased flow of blood to the muscles is helpful to restore inactive muscles that have become weak from disuse due to injury or illness, leading to a more complete recovery once a patient become ambulatory.
Pain relief
Instructors at the Avalon School of Massage report that massage eases muscle pain and can relieve discomfort following muscles strains, accidents and illnesses. In addition to directly easing tight muscles, massage can help to boost the body's immune system, leading to quicker healing. Massage typically leaves patients more relaxed, allowing for a more positive, stress-free attitude, which also leads to quicker healing and continued relaxed muscles. Relaxation massage techniques can release endorphins in the body and reduce the muscle tension often associated with stress and pain. Fascial release techniques focus on the fascia or skin that covers the muscles. Myofascial release stretches both the skin and the muscles and often results in pain relief to other parts of the body as well.
Prevention
Regular massage treatments can help to tone the muscles, leading to fewer injuries. The stroking and kneading of the massage movements help to tone muscles, making them stronger and more pliable and less prone to stress. Massage helps to restore energy levels, leaving patients less fatigued and less prone to injury and muscle failure.
