Question 1

Are isotonic drinks needed for workouts under one hour?

Accepted Answer

For workouts lasting under 60 minutes, plain water is sufficient if nutrition between sessions is normal. Isotonic drinks become important starting from 60-90 minutes of exercise when glycogen stores begin depleting. Exceptions are hot weather or very intense training where electrolyte loss through sweat is greater.

Question 2

What is the difference between isotonic, hypotonic, and hypertonic drinks?

Accepted Answer

Isotonic drinks (6-8% carbohydrates) absorb at blood rate and suit during-exercise use. Hypotonic drinks (under 6%) absorb even faster and suit rapid fluid replacement. Hypertonic drinks (over 8%) provide more energy but absorb slower, making them better suited for post-workout energy recovery.

Question 3

How to choose between an isotonic drink and a gel?

Accepted Answer

Isotonic drinks provide both fluids and energy simultaneously, making them ideal for endurance training where regular drinking is possible. Gels are more compact and quicker to consume — perfect for competitions and situations where drinking is inconvenient. When using gels, ensure you also drink enough water, as gels themselves do not provide fluids.

Question 4

How much isotonic drink should you consume during training?

Accepted Answer

The recommended amount is 400-800 ml per hour, depending on sweat rate, body weight, and temperature. Drink in regular small sips every 10-15 minutes rather than large amounts at once. Excessive fluid intake can cause hyponatremia (low sodium levels), which is more dangerous than mild dehydration.
