Massage is promising for muscle recovery

02.02.2012
McMaster researchers find 10 minutes reduces inflammation

Researchers at McMaster University have discovered a brief 10-minute massage helps reduce inflammation in muscle.

As a non-drug therapy, massage holds the potential to help not just bone-weary athletes but those with inflammation-related chronic conditions, such as arthritis or muscular dystrophy, says Justin Crane, a doctoral student in the Department of Kinesiology at McMaster.

While massage is well accepted as a therapy for relieving muscle tension and pain, the researchers delved deeper to find it also triggers biochemical sensors that can send inflammation-reducing signals to muscle cells.

In addition, massage signals muscle to build more mitochondria, the power centres of cells which play an important role in healing.

"The main thing, and what is novel about our study, is that no one has ever looked inside the muscle to see what is happening with massage, no one looked at the biochemical effects or what might be going on in the muscle itself," said Crane.

"We have shown the muscle senses that it is being stretched and this appears to reduce the cells' inflammatory response," he said. "As a consequence, massage may be beneficial for recovery from injury."

Crane said the McMaster researchers are the first to take a manual therapy, like massage, and test the effect using a muscle biopsy to show massage reduces inflammation, an underlying factor in many chronic diseases.

The research appears in the Feb. 1 issue of Science Translational Medicine.

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.

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.

Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....

Im Focus: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...

Im Focus: World record: Fastest 3-D tomographic images at BESSY II

The quality of materials often depends on the manufacturing process. In casting and welding, for example, the rate at which melts solidify and the resulting microstructure of the alloy is important. With metallic foams as well, it depends on exactly how the foaming process takes place. To understand these processes fully requires fast sensing capability. The fastest 3D tomographic images to date have now been achieved at the BESSY II X-ray source operated by the Helmholtz-Zentrum Berlin.

Dr. Francisco Garcia-Moreno and his team have designed a turntable that rotates ultra-stably about its axis at a constant rotational speed. This really depends...
