Hydration for Water Polo Athletes

At Saturday, we firmly believe in the powerful impact of sports nutrition on improving athletic performance. We aim to spotlight the key area of hydration management, which is of significant importance in maintaining optimal performance levels, particularly for those involved in water polo.

Comprehending Dehydration and Its Impacts on Performance

Minor dehydration, as slight as a 2% loss in body weight due to water loss, can negatively impact an athlete's performance by reducing cardiac output – the quantity of blood pumped by the heart each minute. This increased burden on the heart can have significant performance repercussions.

More severe levels of dehydration can result in a decrease in muscle power owing to the reduction in blood volume. This hampers the effective distribution of nutrients and oxygen to the muscles. Further, a considerable loss of fluid reduces the body's cooling ability via sweating, potentially leading to an increase in body temperature and a corresponding decline in performance.

Striking a Balance: Hydration and Sodium Levels

Achieving an equilibrium between hydration and sodium levels is essential during high-intensity sports activities like water polo. While dehydration is a considerable concern, it is equally crucial to avoid overhydrating without a sufficient intake of salts. This can lead to hyponatremia – a potentially dangerous condition characterized by low sodium concentration in the blood. Symptoms of hyponatremia, such as headaches, confusion, tiredness, and muscle weakness, can often mirror those of dehydration.

To avoid hyponatremia, athletes are typically advised to consume a hypotonic solution during exercise. However, if they fail to consume enough of this, a hypertonic solution may be required to replace the sodium lost through sweat.

Fluid Intake Guidelines and Concentrations

Generally, athletes can ingest around 0.8-1.5L of fluid per hour of rigorous activity without experiencing discomfort in the gastrointestinal system, as long as the sugar and electrolyte concentration in the drink does not exceed that of bodily fluids. Concentrations between 10-14% are often most beneficial. For activities lasting less than three hours, consuming a hyper-concentrated carbohydrate solution may prove advantageous as the need for carbohydrate energy may outweigh the requirement for optimal hydration.

Adapting Electrolyte Needs

During high-intensity activities like water polo, electrolyte intake needs to be personalized to the individual athlete. Sodium requirements can range from 500-1500mg/L depending on sweat rate, sweat composition, and environmental conditions like temperature and humidity. As a general rule, the more you sweat, the more sodium you need to consume per liter to compensate for losses.

Options for Sodium Replenishment

There are several alternatives for sodium replenishment that athletes can utilize, from sports drinks to gels and tabs. However, one cost-effective solution that is often overlooked is regular table salt. Sodium citrate serves as another efficient choice as it delivers more sodium ions than table salt. Sodium citrate disassociates into three sodium ions and one citrate ion, whereas table salt breaks down into one sodium ion and one chloride ion. This makes sodium citrate a more potent source of sodium that places less strain on the gastrointestinal tract.

In Conclusion

For water polo athletes, adept hydration management is key to peak performance. Strive to balance your fluid and sodium intake to prevent both dehydration and hyponatremia. Customize your fluid and electrolyte intake to match your personal needs and the specific requirements of the sport.
