Hydration & Electrolytes for Performance
Hydration is often overlooked in sports nutrition. Even mild dehydration reduces performance, strength, and endurance.
Electrolytes — particularly sodium and potassium — support nerve signaling and muscle contraction.
Why Hydration Matters
A 2% loss in body water can measurably reduce strength, power, and cognitive function. Athletes in hot environments or long sessions are at highest risk.
Key Electrolytes
Sodium
The primary electrolyte lost in sweat. Critical for fluid balance and nerve function.
Potassium
Supports muscle contraction and heart rhythm. Found in bananas, potatoes, and electrolyte supplements.
Magnesium
Involved in over 300 enzymatic reactions. Supports sleep, recovery, and muscle relaxation.
When Electrolytes Matter Most
- Long practices (90+ minutes)
- Hot environments
- Multiple sessions per day
- Heavy sweaters
Frequently Asked Questions
- How much water should athletes drink?
- It varies by body size, climate, and training volume. Monitor urine color — pale yellow indicates adequate hydration.
- Do I need electrolyte supplements?
- During long practices, hot environments, or multiple sessions per day — yes. For short, moderate training — water is usually sufficient.
