Recently I read an article about the sorts of injuries you can get if you're a dedicated runner. Each injury had a specific name, and here they are:
Overtraining Syndrome
Runner's Anemia
Snapping Hip
Dead Butt Syndrome
Say what?
That last one is an inflammation of the tendons in the gluteus maximus, caused by having weak glutes. Runners who don't cross-train are prone to it.
The symptoms are a sharp pain in the hip, and discomfort sitting for long periods.
The cure is to cut back on running and do strengthening exercises. Deep tissue massage is recommended to break up the scar tissue and increase blood flow to the buttocks.
That's very intriguing, since the syndrome sounds very much like the after-effects of a good spanking. My butt is usually numb, and I experience the same symptoms.
As for the cure, "deep tissue massage" is probably a euphemism for spanking.
