Muscle tissue can occur due to overuse of degeneration, necrosis, structure disorder pathological changes, such as massage, directly or indirectly, to promote contraction of the muscle fibers and stretching, muscle activity and can promote the blood and lymph fluid circulation, thus improving the nutritional status of the muscle, enhancing the muscle tension, elastic and tolerance. But muscle movement, the oxygen consumption, energy consumption, produce metabolism of lactic acid and other harmful substances, and make the tissue fluid into acid, can produce local tissue acidosis, fatigue, appear acid bilges use massage muscles can get sufficient oxygen and nutrients, and the tissue fluid absorption of lactic acid and other harmful metabolites or out of the body, to eliminate muscle fatigue, Improves muscle vitality and endurance. Because of this, the Flying Bear FX-Sport series pulse Leg recovery system can effectively and quickly recover after exercise.
