The Importance of Electrolytes During Exercise

What are electrolytes and why are they so important?

Electrolytes are minerals that carry an electrical charge and are essential for nearly every function in your body. When you exercise, especially in hot environments or during intense training, your body loses electrolytes through sweat.

Key Electrolytes

Sodium (Na+)

• Regulates fluid balance in your body
• Helps transmit nerve impulses
• Essential for muscle contraction
• Average loss: 500-1000mg per hour of exercise

Potassium (K+)

• Crucial for muscle function
• Helps regulate blood pressure
• Important for heart function
• Average loss: 150-300mg per hour

Magnesium (Mg2+)

• Participates in more than 300 enzymatic reactions
• Essential for energy production
• Helps prevent muscle cramps
• Average loss: 15-30mg per hour

Calcium (Ca2+)

• Fundamental for muscle contraction
• Important for bone health
• Helps blood clotting
• Average loss: 10-20mg per hour

Signs of Electrolyte Imbalance

Your body sends clear signals when electrolyte levels are out of balance:

1. Muscle cramps: Especially in your legs and feet
2. Excessive fatigue: Feeling more exhausted than usual
3. Dizziness or confusion: Difficulty concentrating
4. Nausea: Stomach discomfort during or after exercise
5. Irregular heartbeat: Palpitations or erratic beats
6. Headaches: Especially after training

The Science Behind Hydration

When you sweat, you lose water and electrolytes. If you only replace the water without electrolytes, you can create a dangerous imbalance called hyponatremia (low blood sodium concentration).

“It is not enough to drink water. Electrolytes are the key to truly effective hydration.” - Sports Medicine Institute

The Perfect Balance

bilan is scientifically formulated to provide:

• Optimized sodium: To replace sweat losses
• Ideal Na:K ratio: 3:1, similar to sweat composition
• Bioavailable magnesium: For cramp prevention
• Balanced calcium: For optimal muscle function

When and How to Hydrate

Before Exercise (1-2 hours before)

• 400-600ml of electrolyte solution
• Ensures optimal levels before you start

During Exercise

• 150-250ml every 15-20 minutes
• Adjust according to intensity and temperature
• Don’t wait until you feel thirsty

After Exercise (first 2 hours)

• 150% of the weight lost in fluids
• Continue replacing electrolytes
• Pair with nutrient-rich foods

Real Success Stories

Triathlete - María Fernández

“Before using bilan, I had constant cramps during long training sessions. Now I can finish my sessions without problems and my recovery is much faster.”

Marathon runner - Roberto Sánchez

“The difference is obvious. My times improved and I no longer finish races feeling completely drained. Electrolytes make all the difference.”

Conclusion

Electrolytes are not a luxury; they are a necessity for anyone who exercises regularly. Whether you are a professional athlete or simply someone who likes to stay active, replacing electrolytes properly will help you:

• ✓ Improve performance
• ✓ Prevent cramps and fatigue
• ✓ Speed up recovery
• ✓ Maintain optimal health
