If you're a runner looking to improve your hydration and performance, then you've come to the right place! Today, we'll look at how and when to consume your electrolytes during your running sessions.
The basics: What is an electrolyte and why is it essential?
To understand how electrolytes can help you with running, let's start by defining what an electrolyte is.
Electrolytes are essential minerals (sodium, potassium, magnesium, and calcium) present in our bodies. Their role is to maintain our body's fluid balance, i.e., the amount of water present in the body. Furthermore, they are crucial for muscle contraction and relaxation. Sodium and calcium trigger contraction, while potassium and magnesium affect relaxation. Finally, they enable better nerve transmission; it is the movement of electrolytes through neuronal cells that creates electrical signals.
Running and hydration: a delicate balance
Hydration plays a very important role in a runner's performance and therefore needs to be optimized.
During physical exertion like running, our body temperature rises, and it uses sweat to regulate it. However, this loss of sweat also leads to a significant loss of electrolytes. Sodium is the electrolyte lost most quickly and in the largest quantities, so it's important to replenish it.
Not all efforts are equal in terms of losses. Duration, intensity, and climatic conditions are important factors to consider when evaluating your sweat loss, and therefore the water and electrolytes lost.
The effects of an electrolyte imbalance can be debilitating in the short or medium term. For example, you might experience cramps or quickly feel fatigued after this imbalance. In the longer term, your recovery might be slower, and you'll have a higher risk of injury.
To avoid these inconveniences, try to drink before, during, and after your run, taking small sips. However, if your effort exceeds 1 hour, it is advisable to supplement your hydration with electrolytes. Finally, adopting a balanced diet can also help with this.
Why do runners have increased electrolyte needs?
Running causes a significant loss of water and electrolytes through perspiration, which increases needs compared to a sedentary person. This increase also concerns other electrolytes. During a one-hour run, a runner loses on average 1200 mg of sodium, 400 mg of potassium, 30 mg of calcium, and 20 mg of magnesium. However, the daily needs for a sedentary person are 2500 mg for potassium, 1000 mg for calcium, and 350 mg for magnesium.
Several factors specific to running explain this increased demand for electrolytes. Sweat eliminates minerals, while increased heart rate and intensity of muscle contraction require sufficient intake to maintain performance and prevent premature fatigue. Sodium is essential for retaining water and preventing dehydration, while potassium and calcium play a key role in muscle contraction, ensuring effective nerve transmission and limiting the risk of cramps.
An adequate intake of electrolytes therefore optimizes hydration and prevents performance drops related to mineral imbalances.
How and when to consume electrolytes?
It is important to know when and how to consume electrolytes for optimal hydration.
For your information, electrolytes are present in isotonic drinks, electrolyte drinks, and some foods. Isotonic drinks contain water, electrolytes, and a carbohydrate source, which distinguishes them from electrolyte drinks, which do not necessarily contain sugar or contain it in smaller quantities. Thanks to their composition, electrolytes are particularly suitable for prolonged efforts or hot climatic conditions, as they help maintain the body's fluid balance.
It is also possible to get an electrolyte intake through foods like banana, rich in potassium; avocado, which is a very good source of magnesium and potassium, as well as dried fruits or seeds. Having a balanced diet adapted to your needs is important and allows you to consume your electrolytes in another way.
Regarding the timing of consumption, it is recommended to distribute electrolyte intake before, during, and after exercise:
Before: to optimize initial hydration and build up sufficient reserves.
During: to maintain fluid balance and prevent dehydration, it is advisable to drink at regular intervals, approximately every 15 to 20 minutes.
After: to promote recovery, restore electrolyte losses, and effectively rehydrate the body.
A well-distributed intake adapted to the intensity of the effort indeed improves endurance, limits fatigue, and optimizes sports performance.
Our practical tips for using electrolytes effectively in running
To determine if you have an electrolyte deficiency, you should look for several symptoms, namely abnormal fatigue, muscle cramps, dark urine, or nausea, all of which can be signs of a deficiency.
Adapt your strategy based on conditions and effort:
In hot and humid weather, sweating is more abundant and leads to increased electrolyte loss, particularly sodium. It is therefore important to increase intake to compensate for these losses.
In cold weather, hydration needs are often underestimated, but losses also occur, particularly through breathing and perspiration. Even if the sensation of thirst is less present, a sufficient intake of electrolytes remains essential.
If your effort lasts more than an hour, it is recommended to consume an isotonic drink in addition to an electrolyte drink to maintain fluid balance and preserve energy. Below an hour, water alone may suffice, but it is not optimal for performance and recovery. We therefore advise adding electrolytes.
During preparation, it is crucial to test the drinks and dosages you will use in competition during training. Testing your electrolyte intake helps avoid digestive problems or inadequate hydration that could hinder your performance on race day!
To facilitate your hydration, Hydratis has designed electrolyte tablets that will allow you precise, simple, and effective dosing. Many athletes have already trusted us and use our products in their daily training. In addition to their hydrating qualities, these tablets will enhance your drinks by providing the flavor you choose from a dozen options (lemon elderflower, forest fruits, coconut, neutral, etc.).
Hydration is a performance factor in running, and neglecting it can lead to muscle cramps, decreased endurance, or more difficult recovery. According to some scientific studies, dehydration of 1 to 2% could lead to a 10 to 20% drop in physical and cognitive performance! Good electrolyte management thus optimizes fluid balance, maintains muscle efficiency, and allows for good thermoregulation of the body.
Thanks to the advice discussed in this article, you now have all the keys to adjust your electrolyte intake based on your training, climatic conditions, and the duration of your effort. By adopting an adapted hydration strategy, you will maximize your chances of performing and recovering effectively!
