Isotonic – for Whom?
Regularly training, we wonder if we should drink sport drinks, how often and which one will be suitable for us. Certainly, drinking isotonic drinks is not for everyone. People whose training session lasts less than an hour (for example, strength training, practicing aerobics, swimming or running) only need fluid replenishment, preferably just water. There is no need to top up electrolytes or carbohydrates.
With an effort of 1-3 hours (for example, football, cycling, longer running), it is necessary to provide carbohydrates in addition to water. This prevents overheating of the body and a decrease in energy.
Effort lasting more than 3 hours requires replenishment of both water, carbohydrates and electrolytes (especially sodium). Studies have shown that during intense training, athletes can lose up to 2 grams of salt per liter of sweat. Complementing their deficiencies is crucial not only for our performance but also for health.
