BACKGROUND Hyponatremia has emerged as an important cause of race-related death and life-threatening illness among marathon runners. [] Key Method Subjects completed a survey describing demographic information and training history. After the race, runners provided a blood sample and completed a questionnaire detailing their fluid consumption and urine output during the race. Prerace and postrace weights were recorded.

Hyponatremia Among Runners in the Zurich Marathon

A relatively low incidence of EAH was observed in subjects running the marathon in around 2.5 to 5 hours and in a cool environment and there was a direct correlation between fluid intake and plasma sodium change during the race and postrace sodium levels correlated with body mass change.

A Study of Serum Sodium Level Among Hong Kong Runners

Hypernatremia was seen in runners who were better trained before the race, those who performed better, and those who drank less water after the race; this is the largest prospective observational cohort study of dysNatremia conducted on athletes completing a standard marathon in Asia.

Incidence of Hyponatremia During a Continuous 246-km Ultramarathon Running Race

The incidence of EAH of 52 and 65%, when excluding or including these individuals with pre-race hyponatremia, was the highest reported in current literature.

The incidence of exercise-associated hyponatraemia in the London marathon

Four of the 11 hyponatraemic runners lost weight over the course of the marathon, strengthening the case for an additional factor, such as inappropriate antidiuretic hormone release during exercise, in the development of EAH.

Hyponatremia in Marathon Runners due to Inappropriate

Cases of EAH fulfill the essential diagnostic criteria for the syndrome of inappropriate antidiuretic hormone secretion (SIADH), and release of muscle-derived interleukin-6 may play a role in the nonosmotic secretion of arginine vasopressin, thereby linking rhabdomyolysis to the pathogenesis of E AH.

Hyponatremia in marathon runners due to inappropriate arginine vasopressin secretion.

Hyponatremia is Associated With Higher NT-proBNP Than Normonatremia After Prolonged Exercise

The hypothesis that overconsumption of hypotonic fluids in this setting is the most important cause of EAH is supported, as exercise-associated hyponatremia was found in 4.5% of the study group and was associated with weight gain during a prolonged bike ride.

A Case of Severe Exercise Associated Hyponatremia after Running Marathon

The patient’s conscious level improved after hypertonic saline and plasma sodium level corrected and he regained full consciousness 3 days after admission and was discharged in good condition.

Hyponatraemia : identification and evaluation in the marathon medical area.

Pre-race education addressing early symptoms and expected weight changes as well as follow-up instructions detailing the appropriate post-race fluids should be available to all registered runners and specifically given to those runners monitored/treated in the medical area.

Sodium Supplementation and Exercise-Associated Hyponatremia during Prolonged Exercise.

It is concluded that a low sodium intake in supplements has minimal responsibility for development of hyponatremia during continuous exercise up to 30 h, whereas overhydration is the primary characteristic of those developing hypon atremia.

Hyponatremia in runners requiring on-site medical treatment at a single marathon.

This study found a 5.6% incidence of hyponatremia in marathon runners requiring medical treatment on-site and attempted to assess the contribution of fluid type ingested and nonsteroidal antiinflammatory drug (NSAID) use to the development of Hyponatremeia.

The Incidence, Risk Factors, and Clinical Manifestations of Hyponatremia in Marathon Runners

Vomiting was the only clinical sign differentiating hyponatremia from other conditions that induce exercise-associated collapse, and there were no significant differences in vital signs, training variables, or NSAID use between H and NH groups, although there was a trend towards the less experienced runners presenting with lower post-race sodium levels.

Hyponatremia in ultradistance triathletes.

Although mild hyponatremia was associated with variable body weight changes, fluid overload was the cause of most (73%) cases of severe, symptomatic Hyponatremeia, a common biochemical finding in ultradistance triathletes but usually asymptomatic.

The incidence of hyponatremia during prolonged ultraendurance exercise.

Data suggest that, although symptomatic hyponatremia occurs in less than 0.3% of competitors during prolonged exercise even when they ingest little sodium chloride, it is found in a significant proportion (9%) of collapsed runners.

Hyponatremia, Cerebral Edema, and Noncardiogenic Pulmonary Edema in Marathon Runners

It is demonstrated that in healthy marathon runners, noncardiogenic pulmonary edema can be a clinical manifestation of hyponatremic encephalopathy.

Hyponatremia associated with overhydration in U.S. Army trainees.

The authors conclude that hyponatremia resulted from too aggressive fluid replacement practices for soldiers in training status and field medical policy should recognize the possibility of overhydration.

A recent report that a female participant in the 2002 Boston marathon died from hyponatraemic encephalopathy because she ingested excessive volumes of a sports drink before and during the race exposes an emotive debate that has raged for more than a decade about how much should athletes drink during exercise.

Death from hyponatremia as a result of acute water intoxication in an Army basic trainee.

The first known death of an Army basic trainee as a result of acute water intoxication is reported, and the misinterpretation of his symptoms as those of dehydration and heat injury led to continued efforts at oral hydration until catastrophic cerebral and pulmonary edema developed.
