There’s a lot of talk about the idea of using Eccentric Exercise in Tennis Elbow rehab, but can one type of muscle contraction really be that much more effective for your tendon healing?

Or is the eccentric approach, and the FlexBar rubber bar device often used to perform it, just another gimmick?

(An Eccentric contraction is the controlled lengthening of a muscle against resistance, and a Concentric contraction is where the muscle shortens.)

Based on several medical studies, there is evidence to back up the idea that Eccentric muscle contractions may (in some cases) be superior to concentric ones when it comes to tendon rehab.

(A lot of the buzz around this idea seems to revolve around a single study, a small, but apparently successful study of Tennis Elbow sufferers.)
