If you're a runner looking to improve your hydration and performance, then you've come to the right place! Today, we're going to explore 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 in running, we will start by defining what an electrolyte is.
Electrolytes are essential minerals (sodium, potassium, magnesium, and calcium) that are present in our body. Their role is to maintain our body's water balance, meaning the amount of water present in the body. Additionally, they are essential for muscle contraction and relaxation. Sodium and calcium trigger contraction, while potassium and magnesium influence relaxation. Finally, they allow for better nerve transmission; the movement of electrolytes across neuronal cells creates electrical signals.
Running and hydration: a delicate balance
Hydration plays a very important role in a runner's performance and is therefore important to optimize.
During physical exertion like running, our body temperature rises and uses sweat to regulate it. However, this loss of sweat also leads to a significant loss of electrolytes. Sodium is the one that is lost most quickly and in the largest quantities, so it is important to replace it.
Not all efforts are equal in terms of losses. Duration, intensity, and climatic conditions are important factors to consider when evaluating your perspiration 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 may experience cramps or feel fatigued quickly after this imbalance. In the longer term, your recovery may be slower, and you will therefore 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 leads to significant loss of water and electrolytes through perspiration, which will increase the 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. Perspiration eliminates minerals, while the increased heart rate and intensity of muscle contraction require a sufficient supply to maintain performance and avoid premature fatigue. Sodium is essential for retaining water and preventing dehydration, while potassium and calcium play a key role in muscle contraction, ensuring efficient nerve transmission and limiting the risk of cramps.
An appropriate electrolyte intake therefore helps to optimize hydration and prevent performance drops linked to mineral imbalances.
How and when to consume electrolytes?
It is important to know when and how to consume electrolytes, so that your hydration is optimal.
For information, electrolytes are present in isotonic drinks, electrolyte drinks, and certain foods. Isotonic drinks contain water, electrolytes, and a source of carbohydrates, which distinguishes them from electrolyte drinks, which do not necessarily contain sugar or 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 water balance.
It is also possible to get an electrolyte intake through foods such as bananas, rich in potassium; avocados, which are 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 water 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 effectively improves endurance, limits fatigue, and optimizes athletic performance.
Our practical tips for using electrolytes effectively in running
To find out if you are lacking electrolytes, you need to monitor several symptoms, namely abnormal fatigue, muscle cramps, dark urine, or even nausea, which can be signs of a deficiency.
Adapt your strategy based on conditions and effort:
In hot and humid weather, perspiration is more abundant and leads to increased electrolyte loss, particularly sodium. It is then important to increase intake to compensate for these losses.
In cold weather, we often underestimate our hydration needs, but losses also occur, especially through breathing and sweating. 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 you to add electrolytes.
During preparation, it is essential to test, during training, the drinks and dosages that you will use in competition. Testing your electrolyte intake helps to avoid digestive problems or inadequate hydration that could harm your performance on race day!
To facilitate your hydration, Hydratis has designed electrolyte tablets that will allow you a precise, simple and effective dosage. Many athletes have already trusted us and use our products in their daily training. In addition to their hydration 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, 1 to 2% dehydration could lead to a 10 to 20% decrease in physical and cognitive performance! Good electrolyte management thus helps to optimize fluid balance, maintain muscle efficiency, and allow for good body thermoregulation.
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!
