Isotonic & Energy Drinks

Yes, of course! On decathlon.com.gr you will find a complete collection of sports hydration and energy drinks. Our range includes isotonic drink powders, ready-to-drink liquid beverages, effervescent tablets, as well as energy drinks/gels designed for running, cycling, triathlon, and all types of intense training.

An isotonic drink is versatile and can be used during all stages of exercise. Consuming it during training is its primary use and the most suitable time. By sipping small amounts every 10-15 minutes during workouts lasting over 60 minutes, you maintain steady energy levels (carbohydrates) and replenish the fluids and minerals lost through sweat.
Before training, you can drink a few sips 30 minutes before starting to ensure optimal hydration and topped-up energy stores.
After training, consuming an isotonic drink aids in the rapid replenishment of lost glycogen and electrolytes, accelerating recovery.

An isotonic drink has the same concentration of electrolytes and carbohydrates (4-8%) as body fluids. Its main goal is rapid hydration while simultaneously providing steady energy without overburdening the stomach.
An energy drink is usually a hypertonic solution with high sugar content and often contains stimulants (such as caffeine, taurine, or guarana). It aims to stimulate the central nervous system directly rather than support proper hydration during exercise.

Strictly speaking, an "isotonic" drink requires a specific amount of carbohydrates/sugars (4-8%) to match blood osmolarity for instant absorption. However, at Decathlon you will find sugar-free electrolyte drinks that do not provide calories or energy, but are ideal for low-intensity workouts, for individuals looking to avoid calories, or for training in hot weather where the sole objective is mineral replenishment.

For long runs (long runs/marathons), the general recommendation is to consume 500 ml to 750 ml of isotonic drink per hour of exercise. For runs lasting up to 60 minutes, plain water is usually sufficient, while for runs exceeding 60-90 minutes, estimate about 1 bottle (500 ml) of prepared isotonic drink for every hour of running, taking 2-3 sips every 10-15 minutes.
