Researchers testing the long-held theory that therapeutic massage can speed recovery after a sports injury have found early scientific evidence of the healing effects of massage. The scientists have determined that immediate cyclic compression of muscles after intense exercise reduced swelling and muscle damage in a study using animals. Scientific confirmation Though they say it’s too soon to apply the results directly to humans in a clinical environment, the researchers consider the findings a strong start toward scientific confirmation of massage’s benefits to athletes after intense eccentric exercise, when muscles contract and lengthen at the same time. “There is potential that this continuing research will have huge clinical implications,” said Thomas Best, a professor of family medicine at the Ohio State University and senior author of the study. “If we can define the mechanism for recovery, the translation of these findings to the clinic will dictate how much massage is needed, for how long, and when it should be performed after exercise.” Anecdotal evidence suggests massage offers many health benefits, but actual testing of its effects at the cellular level is more difficult than one might think. In this study with rabbits, the researchers used one mechanical device to mimic movements associated with a specific kind of exercise, and a second device to follow the exercise with a simulated consistent massaging motion on the affected muscles. They compared these animals to other animals that performed the exercise movements but did not receive simulated massage. All animals were sedated during the experiments. Massage mechanism unknown “We tried to mimic Swedish massage (combining long strokes, kneading and friction techniques on muscles and various movements of joints) because anecdotally, it’s the most popular technique used by athletes,” said Best, who is also co-medical director of the OSU Sports Medicine Center and a team physician for the Department of Athletics. “A review of the research in this area shows that despite the existing anecdotal evidence – we know athletes use massage all the time – researchers don’t know the mechanism of how massage improves recovery after exercise and injury.” After the experimental exercise and massage were performed in the study, the researchers compared the muscle tissues of all of the animals, finding that the muscles in animals receiving simulated massage had improved function, less swelling and fewer signs of inflammation than did muscles in the animals that received no massage treatment after exercise. Eccentric exercise The research focused on eccentric exercise, which creates a motion similar to the way in which quadriceps in human thighs are exercised during a downhill run. In the study, the scientists focused on the tibialis anterior muscle, located on the front of the shin in humans. The simulated...
