Many people enjoy getting massages for relaxation and tension relief. Now, scientists suggest that massage may also reduce post-exercise inflammation and improve recovery.
A report published in Science Transitional Medicine (2012; 4 [119], 119ra13) focused on what happens to the muscle at a physiological level when massage is applied after intense exercise. The test subjects, 11 young males, underwent resting muscle biopsies of the right and left vastus lateralis before the intervention. They then exercised at a high-intensity level for about 70 minutes.
Once the exercise protocol was complete, a licensed massage therapist massaged one leg of each participant for 10 minutes; the other, non-massaged leg of each participant acted as a control. The scientists were not told which leg had been massaged. Participants underwent two more rounds of biopsies on each leg: one immediately postmassage and the other 2.5 hours later. Researchers used microarray technology to measure abundance of mRNA (messenger RNA).
?Pathways that were apparent reflected an increase in mitochondrial biogenesis and a decrease in inflammation,? explained lead author Mark Tarnoplosky, MD, PhD.
?The overall theme of the biomechanical work is that the pathways for mitochondrial biogenesis appear to be enhanced and those pathways involved in the muscle inflammatory response appear to be attenuated in the massaged leg post-exercise,? Tarnopolsky added.
