Rhabdomyolysis is the breakdown of damaged skeletal muscle. Muscle breakdown causes the release of myoglobin into the bloodstream. Myoglobin is the protein that stores oxygen in your muscles. If you have too much myoglobin in your blood, it can cause kidney damage. About 26,000 cases of rhabdomyolysis are reported in the United States each year.
Cause of Supination. Supination occurs as the foot tilts to the outside. Supination is the rolling of the foot to the outside during normal walking or running motions. The term is usually used in connection with over-supination, which means that the arch of the foot is too high and too much weight is placed on the outside of the foot.
The problem with underpronation â or supination â is that the foot is not in the right position to allow for optimum weight distribution, and the structures of the foot which help with the cushioning of shocks (the foot arches and plantar fascia) cannot work efficiently.nderpronation can be caused by structural abnormalities in the feet or when previous injuries to the feet have damaged the tendons and muscles, or when there is muscle imbalance or a particularly tight Achilles tendon.
