Formula
## How to Mix a Sports Drink ### Carbohydrate Concentration Sports drinks should be 4-8% carbohydrate for optimal absorption: - **Light activity**: 4-5% (lower end) - **Moderate activity**: 5-6% - **Intense activity**: 6-8% Concentrations above 8% slow gastric emptying and can cause stomach issues. ### Sodium Add 0.5-1.0 g of sodium per liter of water. This replaces sweat losses and improves fluid absorption. Heavy sweaters may need more. ### Mixing Dissolve sugar and salt in warm water, then add cold water and ice. Taste should be mildly sweet, not overpowering.
Exemplo Resolvido
Mix a sports drink for a 1.5-hour moderate run using 750 mL of water.
- 01Carb percentage = 4 + 1 x 2 = 6%.
- 02Sugar = 750 x 6/100 x 1 = 45 g (about 3 tablespoons).
- 03Salt = 750 x 0.001 x 1 = 0.8 g (about 1/8 tsp).
- 04Total fluid needed = 750 x 1.5 = 1125 mL.
- 05Bottles = ceil(1125 / 750) = 2 bottles.
Perguntas Frequentes
Can I use regular table sugar?
Yes. A mix of sucrose (table sugar) and glucose works well. For even better absorption, use a 2:1 ratio of glucose to fructose, which allows the gut to absorb more carbohydrate per hour via different transporters.
Do I need a sports drink for short workouts?
For activities under 60 minutes at moderate intensity, plain water is sufficient. Sports drinks become beneficial for sessions over 60-90 minutes, in high heat, or during intense effort.
How much should I drink per hour?
General guideline: 400-800 mL per hour, depending on sweat rate, temperature, and body size. Weigh yourself before and after exercise. Each pound lost equals about 480 mL of fluid deficit.
