摘要

Hyponatremia among marathon runners and endurance athletes has become an emerging topic for research and public concern following reports of serious illness and death. Weight gain due to excessive fluid consumption during the marathon race was proposed to be a major factor in the development of hyponatremia. We hypothesized that hyponatremia immediately following marathon completion is less common than previously reported and that post race fluid consumption is a critical factor in the development of hyponatremia. Blood, urine samples and body weight were collected up to 2 hours prior to start of the race, at race completion and at 1 hour after the race in 133 full and half marathon runners. At the race finish, each runner completed a brief questionnaire documenting consumption of fluids during the race. Serum sodium for all participants slightly increased from baseline (141.0+1.72 mmol/L) to race completion (141.8±3.09 mmol/L; p=0.0154), but significantly reduced one hour after race completion (139.4±2.99 mmol/L; p<0.0001). Hyponatremia was identified in none of the participants prior to the race, but was found in 3 of 119 runners (2.52%) at race completion and in 8 of 84 runners (9.52%) 1-hour post-race. Runners with normal sodium levels lost 1.02±0.14 Kg of body weight from race start to 1 hour post-race, whereas, runners with hyponatremia gained 0.33±0.06 kg, p<0.01. Hyponatremia during marathon participation is less prevalent than previously reported. Our study demonstrates that hyponatremia is a consequence of excessive intake of hypotonic fluids following race completion.
