Dr. Bonci explained in detail the physiological origin and effects of trigger points on muscles, exactly what Drs. Nimmo, Travell, and Simons had been teaching for years. Trigger points are nodular accumulations of toxins that attach to muscle fibers (part of the muscle) that have been used repetitively, or injured, and cause chaos in muscles.
This physiological process begins with muscular activity. Most of us engage in repetitive muscle activities every day. This repetition produces toxins, some of which are carried away and flushed out of the system. But some toxins accumulate and attach themselves to muscle fibers, becoming trigger points. Once trigger points develop, there is a reduction in blood flow to that muscle fiber and a subsequent shortening of that fiber. In muscle physiology, length equals strength, so the strength of a muscle is determined by the strength of the shortest fiber. This process reduces the length and strength of the muscle and increases the likelihood of injury.
Because our current healthcare system does not address the presence of trigger points, many of our muscular injuries are treated without our ever addressing their causes. My calf muscles pulled every time I ran because the accumulation of toxins over my many years of running left little margin for more stress without the involved fibers pulling again.
