Electrolyte Replacement Rate Calculator

Calculate hourly electrolyte replacement needs (sodium, potassium, magnesium) during endurance exercise based on sweat rate and electrolyte concentration

Each component has a specific meaning:

• Sweat rate — The sweat rate recorded for the scenario being assessed.
• Electrolyte concentration — The electrolyte concentration recorded for the scenario being assessed.

Note: Interpret the electrolyte rate result against the thresholds and context described above.

Enter the sweat rate, electrolyte concentration for the scenario you are assessing. Calculate hourly electrolyte replacement needs (sodium, potassium, magnesium) during endurance exercise based on sweat rate and electrolyte concentration. Use the electrolyte rate result to inform your calculation.
