10 Minutes of Massage Reduces Muscle Inflammation

For their study, the researchers followed 11 men in their twenties. On their first visit, the men's exercise capacity was assessed. Two weeks later, the men cycled on a bicycle for more than 70 minutes, to a point of exhaustion when they couldn't cycle any more. They then rested for 10 minutes.
While resting, a massage therapist lightly applied massage oil to both legs, and then performed massage for 10 minutes on one leg using a variety of techniques commonly used in rehabilitation. Muscle biopsies were done on both legs (quadriceps) and repeated 2.5 hours later. Researchers found reduced inflammation in the massaged leg.
Crane admits being surprised that just 10 minutes of massage had such a profound effect. "I didn't think that little bit of massage could produce that remarkable of a change, especially since the exercise was so robust. Seventy minutes of exercise compared to 10 of massage, it is clearly potent." The results hint that massage therapy blunts muscle pain by the same biological mechanisms as most pain medications and could be an effective alternative.
Dr. Mark Tarnopolsky, professor of medicine for the Michael G. DeGroote School of Medicine, oversaw the study. "Given that mitochondrial dysfunction is associated with muscle atrophy and other processes such as insulin resistance, any therapy that can improve mitochondrial function may be beneficial," he said.
Crane said this study is only a first step in determining the best therapies for promoting recovery from a variety of muscle injuries. He said that surprisingly the research proved one oft-repeated idea false: massage did not help clear lactic acid from tired muscles.
