Sports Hydration - Key to Performance and Recovery

Hydration is an essential component of athletic performance, whether you are a top athlete or an amateur sportsperson. Ensuring a good water balance helps optimize your physical potential, prevent injuries and promote rapid recovery.

Why is hydration essential for athletes?

Hydration is crucial for athletes because it ensures proper muscle function, body temperature regulation, and nutrient circulation. During exercise, sweating causes a loss of water and electrolytes, including sodium, potassium, and magnesium, which are essential for maintaining muscle contraction and preventing cramps. Even mild dehydration can have a significant impact on performance: A loss of 1-2% of body weight in water can lead to a 10-20% decrease in athletic performance.

Dehydration decreases endurance, increases fatigue and slows reaction time.

How to Determine Your Fluid Needs Before, During, and After Exercise

• Before exercise: Drinking between 400 and 600 ml of water about two hours before starting the effort allows you to start in optimal conditions. This gives the body time to absorb and distribute fluids in the tissues.
• During exercise: For activities lasting less than an hour, drinking small amounts of water every 15-20 minutes is often sufficient. For longer or more intense sessions, it is recommended to opt for a drink containing electrolytes to replace sodium and potassium losses.
• After exercise: It is essential to rehydrate after exercise to replace water and electrolyte losses. As a general rule, it is recommended to drink 1.5 times the weight in water lost during exercise (for example, if you lost 1 kg, drink 1.5 liters of water).

Common Hydration Mistakes and How to Avoid Them

• Don't wait until you're thirsty: The feeling of thirst often appears too late. It is better to hydrate at regular intervals before, during and after exercise to anticipate fluid needs.
• Drinking too much or too little water: Over-drinking water can lead to hyponatremia (dilution of electrolytes), while under-drinking can lead to dehydration. Balance is key; listen to your body and watch for signs like the color of your urine.
• Neglecting electrolytes: Sweating causes losses of sodium and potassium, minerals essential for muscle contraction. In case of heavy sweating, isotonic drinks are preferable to water alone.
• Ignoring Urine Specific Gravity: Monitoring urine specific gravity is a great indicator of hydration levels. If your urine is dark, it may indicate dehydration.

Urine density: a reliable indicator of hydration

Urine specific gravity is a direct indicator of hydration status. It measures the concentration of substances in the urine, and the higher it is, the more likely it is to indicate dehydration. In general, an ideal urine specific gravity is between 1.010 and 1.030. For athletes, regularly monitoring urine specific gravity is an effective way to check whether their fluid intake is adequate, especially after intense or prolonged exercise.
