Which sports drink should you choose to optimize your sports performance?
Choose the perfect sports drink for your workout. Hydration, energy, and electrolytes: the keys to pushing your limits.

Table of Contents
Key points to remember:
-
Water is not enough after 1 hour of exercise; choose a specific sports drink.
-
Isotonic drinks for long efforts, electrolytes for short efforts.
-
Favor formulas that combine several carbohydrates and electrolytes.
-
Drink a few sips every 10 to 15 minutes to maintain optimal hydration, aiming for a total consumption of approximately 500 to 700 ml per hour.
-
Adapt your hydration strategy to your sport.
When faced with the challenge of prolonged exercise, your body needs more than just willpower. Hydration and energy intake become key factors in your performance. But in the jungle of sports drinks available on the market, how do you make the right choice? From isotonic drinks to electrolyte complexes, discover how to select the ideal solution to transform each of your workouts.
Why are sports drinks essential for your performance?
Fighting dehydration during exercise
Dehydration is the first danger. A water loss of just 2% of your body weight can reduce your physical capacity by 20% [1]. During sustained exercise, you lose between 0.5 and 2.5 liters of water per hour depending on the intensity and weather conditions [2]. This loss must be gradually replaced to maintain your blood volume and your ability to regulate your body temperature.
For example, a 70 kg athlete losing 1.4 liters of sweat already reaches this critical threshold. This situation can occur in less than an hour of intense exercise, especially in hot or humid conditions. Water losses generally vary between 0.5 and 2.5 liters per hour, depending on the intensity of the effort and environmental conditions. It is therefore essential to compensate for these losses gradually to maintain blood volume and the body's ability to regulate its temperature. Regular hydration, with small sips every 10 to 15 minutes, helps prevent the harmful effects of dehydration on performance.
Carbohydrates to replenish energy reserves
Replace electrolytes lost through sweating
What are the different types of sports drinks and their specificities?
Isotonic drinks: the perfect balance between hydration and energy
Hypotonic drinks: priority given to rapid rehydration
Hypertonic drinks: maximizing energy intake
What composition should you choose for an optimal sports drink?
Behind every sip of an effective sports drink lies a precise and strategic formulation. The difference between keeping pace until the finish line or hitting the proverbial "wall" sometimes comes down to just a few key components.
A truly effective sports drink is based on the perfect balance between its different nutrients and their bioavailability, that is, their ability to be quickly absorbed and used by your body during exercise. It is not just a question of quantity, but above all of quality and synergy between the ingredients.
Carbohydrates
The ideal carbohydrate mix combines different carbohydrate sources to maximize intestinal absorption and provide consistent energy. The combination of maltodextrin, glucose, and fructose allows for different metabolic pathways to be used simultaneously, increasing the amount of carbohydrate your body can absorb per hour of exercise—up to 90g compared to 60g with a single source [5]. This multi-carb approach significantly delays exhaustion and optimizes your endurance.
Electrolytes
Sodium, the main electrolyte lost through sweat, serves three key functions:
-
It stimulates your natural thirst;
-
It accelerates intestinal absorption of water;
-
It limits urinary losses.
At optimal doses (20-30 mmol/L), it maintains your blood volume, essential for your endurance.
Potassium and magnesium, on the other hand, directly support your muscle contractions and nerve transmission. Potassium regulates hydration within your cells, while magnesium prevents cramps and optimizes your energy production during exercise. [6]
Vitamins
B vitamins ( B1, B2, B3, B5, B6) actively participate in energy metabolism and help reduce fatigue, allowing you to maintain your performance level for longer. [7]
How to choose your sports drink according to the duration and intensity of your workout?
The duration and intensity of your exercise directly dictate the type of drink best suited to your specific needs.
For short to moderate efforts (less than 1 hour 30 minutes), your priority remains hydration and maintaining electrolyte balance. An essential electrolyte solution like the one offered by Impulse Nutrition is the ideal choice. This complete mineral complex (sodium, potassium, magnesium, calcium and zinc) optimizes your hydration while supporting your nerve and muscle functions. Its light formula, without unnecessary carbohydrate overload, avoids any digestive discomfort during short but intense efforts [4].
How to use your sports drink effectively during physical activity?
Even the most sophisticated sports drink will only reach its full potential with the right usage strategy. Having the best fuel isn't enough—you also need to know how and when to use it to turn every sip into performance.
Optimal dosage
For Impulse Nutrition's Energy Drink, dilute one sachet (40g) in 500ml of water to obtain a perfectly balanced isotonic solution.
Frequency of consumption
Favor regular intakes of small amounts (150-250 ml) every 15-20 minutes rather than a large amount at once. This strategy optimizes intestinal absorption and maintains a constant energy intake while preventing gastric discomfort.
Strategy according to the sport practiced
Adapt your strategy according to your sport :
-
When cycling, take advantage of the flat sections to hydrate yourself;
-
When trail running, plan strategic refreshment points to consume your energy drink;
-
In triathlon, maximize your hydration during the bike leg to compensate for limitations during the swim and run.
