During intense training or a match, the body loses not only water but also electrolytes (mainly sodium and potassium), which are responsible for proper muscle function and for keeping you properly hydrated.
A homemade isotonic drink can effectively support hydration, replace lost minerals and provide a small amount of energy in the form of easily absorbed carbohydrates, and it is an alternative to shop-bought isotonic drinks.
A sample homemade isotonic drink:
- Still mineral water (medium mineral content) – 1000 ml
- Honey – 60 g
- Salt – 1–2 g
- Citrus juice – to taste
This drink is best consumed during a long training session or straight after it, to speed up recovery and improve hydration.
