Document Summary
Cerebral edema with seizure and possible coma and death. Hyponatremia has been associated with the deaths of several female runners in major marathons, such as boston and houston. Excessive drinking of fluids before, during and after the race. Considerable weight gain over the course of the event. Do not consume fluids in excess before, during, or after exercise. Consume extra salt in days before prolonged exercise. Body weight should not increase during exercise. Consume sports drinks with increased sodium content. Typical sports drink = 20 meq na. However, increased salt intake may be recommended during acclimatization to exercise in the heat (if high temp you are losing more water and sodium) Some recommend about 4-10 grams of sodium, or 10-25 grams of salt (2-5 teaspoons) One recommendation: take salt tablets if water intake exceeds 4 quarts daily associated with sweat losses: average salt tablet contains 0. 5 gram of sodium, take two tablets with each quart of water.
