摘要:
KEY POINTS Sickle cell trait is an inherited condition of the oxygencarrying protein, hemoglobin, in red blood cells。This genetic trait is generally benign, but during maximal exercise, the oxygen levels in muscles can decrease sufficiently to cause some of the red cells to change from the normal disk shape to a crescent or sickle shape。These sickled red ceils can block blood vessels in muscles, kidneys, and other organs and can pose a grave risk for some athletes exercising all - out。
