Your Sweat Rate

1.3L/hour
Total Sweat Loss1.3 Liters

During your exercise, your body transpired 1.3 Liters of water. Your current sweat rate is 1.3 L/hour. To maintain muscular output and cardiovascular stability, try to replace 70-80% of this sweat loss during active sports.

Methodology & Formula: Fluid Differential Formula

Sweat Rate (L/hr) = [Pre-exercise Weight (kg) - Post-exercise Weight (kg) + Fluids Consumed (L) - Urine Output (L)] ÷ Duration (hours).
