Methodology Used in Hydration Needs for Athletes Calculator
The calculator estimates hydration needs using:
1. Total Hydration: \\( H = B + E \cdot (I + T) \\)
2. Baseline: \\( B = 35 \cdot W \\) (mL)
3. Exercise: \\( E = 500 \cdot D \cdot I \\) (mL)
4. Temperature: \\( T = 0.02 \cdot (Temp – 20) \\) (factor, if Temp > 20°C)
Where:
- \\( W \\): Weight (kg)
- \\( D \\): Exercise duration (hours)
- \\( I \\): Intensity factor (low: 1, moderate: 1.5, high: 2)
- \\( Temp \\): Temperature (°C)
Converts to liters, reflecting exercise and heat impacts.
Example Calculation
Sample Input
Body Weight = 70 kg, Exercise Duration = 1.5 hours, Intensity = Moderate, Temperature = 25°C
Step 1: Baseline: \\( B = 35 \cdot 70 = 2450 \\) mL
Step 2: Exercise: \\( E = 500 \cdot 1.5 \cdot 1.5 = 1125 \\) mL
Step 3: Temperature: \\( T = 0.02 \cdot (25 – 20) = 0.1 \\)
Step 4: Total: \\( H = 2450 + 1125 \cdot (1 + 0.1) = 3687.5 \\) mL = 3.69 L
Result: Hydration Need = 3.7 liters/day.
