What matters most
Sodium is the main athlete electrolyte
- Sodium drives fluid balance and helps maintain performance.
- Heavy sweating increases sodium loss quickly.
Spot the pattern
Identify the salty sweater
- Look for white residue on skin, hats, or shirts.
- Pay attention to frequent cramping or a flat feeling after long sessions.
What to use
Choose a sodium source the athlete will actually take
- Sports drinks work well for many training sessions.
- Salt tabs, salted foods, or broth can fill the gap for heavy sweaters.
What Are Electrolytes?
Electrolytes are minerals that carry electrical charge:
Electrolytes are minerals that carry electrical charge:
- Sodium (Na+) - Most important for athletes
- Potassium (K+) - Muscle function
- Magnesium (Mg++) - Muscle/nerve function

Field use
A field protocol coaches can actually repeat
Morning
Check the athlete before practice starts
Dark urine, headache, and an empty bottle are red flags before the session even begins.
During training
Use planned drinking moments
Scheduled drink breaks beat thirst when the day is hot, dry, or altitude-adjusted.
After practice
Replace losses steadily
Push recovery fluids across the next few hours instead of one rushed bottle.
