The issue of sodium concentration in long distance runners is potentially lethal and we've recently gotten a better sense of just how common it is. At the 2002 Boston Marathon, a sample of 488 runners approached randomly at race registration completed a survey prior to the race and, Puma Rihanna Fierce
at the finish line, provided a blood sample, and completed a questionnaire detailing their fluid consumption and urine output during the race. Of these runners, 13 percent had ab.
But other molecular abnormalities are more subtle yet potentially even more dangerous. The alarming scenario med students have drilled into their heads has to do with the hypothetical marathon runner who becomes increasingly delirious after a race. Young doctors are taught to assume that the runner has a profound disturbance of sodium, which actually doesn't come from consuming or losing too much sodium through perspiration; rather it comes from consuming an Puma Velvet By Rihanna inappropriate quantity of water8. The fluid imbalance throws the sodium concentration out of whack, and through a complex mechanism can cause the brain to shrink or swell, particularly if too much water is consumed9.
19 year period7. As it turns out, sudden cardiac death occurred in only four individuals during or immediately following the marathon, an incidence of approximately one in 50,000, which is substantially lower than the annual risk of premature death in the general population. (Of the four who died suddenly, none had prior cardiac symptoms and two had completed several prior marathons. ) Thankfully, and perhaps somewhat surprisingly, the incidence of SCD in marathon runners remains relatively low, possibly because so many are in such good shape to begin with. The concern over the troponin enzyme seems rather straightforward; it should be in the heart, not in the blood stream.
