Science Shows How Massage Eases Sore Muscles

WEDNESDAY, Feb. 1 (HealthDay News) — Having a massage after
strenuous exercise not only feels good, it reduces inflammation in muscles
at the cellular level, researchers have found.

Massage also appears to promote the growth of new mitochondria in
skeletal muscle. Mitochondria are cells’ energy-producing “powerhouses,”
explained the researchers at the Buck Institute for Research on Aging and
McMaster University in Hamilton, Ontario.

For the study, the investigators conducted genetic analyses of muscle
biopsies from the quadriceps of 11 men after they exercised to exhaustion
on stationary bicycles. After the workout, one of each participant’s legs
was massaged. Biopsies from both legs were taken before exercise,
immediately after 10 minutes of massage, and 2.5 hours after the end of
the workout.

The researchers found that massage reduced the activity of
inflammation-inducing proteins called cytokines in muscle cells and
promoted the growth of new mitochondria, according to the study published
in the Feb. 1 online edition of the journal Science Translational
Medicine
.

Many people find that having a massage after exercise reduces muscle
pain. This pain reduction may involve the same mechanisms as those
targeted by common anti-inflammatory drugs, explained Simon Melov, a Buck
Institute faculty member.

“There’s general agreement that massage feels good; now we have a
scientific basis for the experience,” Melov said in an institute news
release.

The findings provide validation for massage, which is growing in
popularity, said lead author Dr. Mark Tarnopolsky, of the pediatrics and
medicine department at McMaster.

“The potential benefits of massage could be useful to a broad spectrum
of individuals including the elderly, those suffering from musculoskeletal
injuries, and patients with chronic inflammatory disease,” Tarnopolsky
said. “This study provides evidence that manipulative therapies, such as
massage, may be justifiable in medical practice.”
