Energy content and composition of placebo and sports drink
| Drink contents | Placebo | Sports drink |
|---|---|---|
| Energy value (kcal/L)* | 6 | 270 |
| Fat (g/L) | 0 | 0 |
| Protein (g/L) | 0 | 0 |
| Carbohydrate (g/L) | 0 | 68 |
| Sucrose (g/L) | 0 | 48 |
| Glucose (g/L) | 0 | 20 |
| Osmolality (mOsmol/kg)* | 29 ± 1 | 349 ± 11 |
| Sodium (mmol/L) | 0 | 18 ± 3 |
| Potassium (mmol/L) | 0 | 3 ± 0 |
*There may be trace amounts of sugars present in the placebo drink which could not be detected by our analysis, thus explaining the energy and osmolality values despite the absence of carbohydrates.
