The NY Times just ran a short piece on a new treatment for tennis elbow: PhysEd: A New Treatment for Tennis Elbow .
in the past two or three years, doctors and researchers have begun focusing on a particular kind of exercise that has shown promise against other achy tendons, especially the Achilles. The program involves eccentric exercises, which aren’t oddball moves but those in which the muscle lengthens as it tenses. Think of a biceps curl. When you raise the dumbbell, your bicep shortens and tightens. That’s a concentric contraction. When you lower the weight, the muscle lengthens, straining against the force of the weight. That’s eccentric.

“There’s a growing body of research showing that eccentric exercises are quite effective in treating Achilles tendonosis” and other tendon problems, Tyler says.
One of those studies was a well-designed 2007 experiment centered on tennis elbow. Conducted in Belgium, it found that eccentric exercises provided considerable relief. But the exercises had to be performed on expensive machines under medical supervision during repeated office visits. “We looked at those results and thought, there has to be an easier, more cost-effective way,” Tyler says.
Which is how they arrived at the rubber bar technique. He and his colleagues realized that a single, unhurried exercise using a tensile bar that looks like an oversized licorice stick could create an eccentric contraction all along the forearm. In the exercise, a person holds the bar upright at his or her side using the hand connected to the sore elbow, then grasps it near the top with the good hand. The top hand twists as the bar is brought around in front of the body and positioned perpendicular to the ground; the sore hand then takes over, slowly untwisting the bar by flexing the wrist. “Afterward, you should be sore,” Tyler says. “That’s how we know it’s effective.”
Eccentric contractions require the muscle to work against a force, in this case the coiled bar. “You can load a tendon so much more eccentrically” than with concentric exercises, Tyler says. “So we think the process may be remodeling the tendon.” Ultrasound studies by other researchers, including the group in Belgium, have shown that damaged tendons typically become less thick, indicating they are less damaged, after a course of strenuous eccentric exercise.
The article has an instructional video, also available on YouTube Isolated eccentrics with flexbar:
I ordered a flexbar at Amazon. $17.17 + shipping. Given the tendonitis I've worked around for years, it seems like a bargain.
Can we get some CrossFitters or other trainers to apply this idea of "isolated eccentrics" to other tendons?
