Calculateur de Taux de Perte d'Hydratation — Formule
## Calculating Sweat Rate
Sweat rate determines how much fluid you need to replace during exercise. Weight loss during exercise is primarily from sweat.
### Formula
**Total Sweat Loss (mL) = (Pre-Weight - Post-Weight) x 1000 + Fluid Consumed**
**Sweat Rate (mL/hr) = Total Sweat Loss / Duration (hours)**
Dehydration beyond 2% of body weight impairs performance. Athletes typically sweat 500-2500 mL/hour depending on intensity, heat, and individual physiology.

Exemple Résolu
An athlete drops from 75 kg to 73.5 kg during 60 minutes of exercise while drinking 500 mL.
- Weight loss = 75 - 73.5 = 1.5 kg = 1,500 mL
- Total sweat = 1,500 + 500 = 2,000 mL
- Sweat rate = 2,000 / 1 hour = 2,000 mL/hr
- Dehydration = 1.5 / 75 x 100 = 2.0%
