Back to school, with its fresh air and renewal, is a good time to resume or start a sport. After the sweet moments of summer relaxation, it's time to get moving again and take care of your body. Whether you're starting a sport for the first time or resuming a training routine, back to school offers the ideal opportunity to set new goals and feel invigorated. In this article, we'll explore a crucial element of any sport: hydration. Let's discover how to maintain adequate fluid balance to fully enjoy your sports activities.

The effects of dehydration on athletic performance

Exercising puts intense demands on our bodies, leading to an increase in body temperature and significant energy expenditure. Unfortunately, dehydration resulting from excessive water loss can have detrimental consequences on our athletic performance and pose a health risk.

Biochemically, dehydration alters the balance of essential electrolytes in our body, such as sodium, potassium, and magnesium. These electrolytes play a crucial role in nerve signal transmission and muscle contraction. An electrolyte deficiency can lead to muscle cramps, spasms, and reduced muscle strength, which impairs our athletic performance.

Furthermore, dehydration leads to a decrease in blood volume, which complicates the adequate transport of oxygen and nutrients to working muscles. Insufficient muscle oxygenation limits their ability to generate energy, thereby reducing endurance and overall performance. In addition, dehydration can lead to an increased heart rate, as the heart has to work harder to compensate for the decreased blood volume.

Sweating is a vital mechanism for regulating body temperature during exercise, but it comes with a significant loss of water. This water loss also leads to the elimination of essential minerals, causing electrolyte imbalances. Muscle soreness after exercise can be exacerbated by these imbalances and dehydration.

It is crucial to understand the impact of soreness, as it can hinder our ability to continue our training and athletic performance. When we are dehydrated, our muscles can fatigue more quickly, be more prone to cramps and post-exercise pain. Adequate hydration plays a major role in maintaining muscle elasticity, thereby reducing the risk of soreness and promoting faster recovery.

Our tips for proper hydration before, during, and after exercise

In line with the recommendations of the World Health Organization (WHO), it is essential to emphasize that adequate hydration is not limited to physical exercise but should be a daily concern. The WHO recommends drinking at least 2 liters of water per day to maintain a healthy fluid balance, thereby strengthening our ability to perform and recover after exertion. Drinking water remains the primary solution for dehydration.

To maximize your athletic performance while avoiding the harmful effects of dehydration, follow these valuable tips before, during, and after your physical activity.

Before exercise, thorough preparation is essential. Start with an adequate warm-up to increase your muscle temperature, improve their flexibility, and prevent injuries. Prioritize a dynamic warm-up, including active stretches, light cardiovascular exercises, and movements specific to your sport.

Regarding hydration, make sure you are well-hydrated before starting. It is recommended to consume between 500 ml and 1 liter of water in the hour preceding your physical activity. However, avoid drinking excessive amounts just before starting, to prevent any feeling of discomfort during exercise. Listen to your body and opt for small, regular sips to maintain adequate hydration.

During exercise, the golden rule is to stay hydrated by drinking regularly. Your needs will vary depending on the intensity, duration of your activity, and environmental conditions. A good practice is to drink approximately 150 to 250 ml of water every 20 minutes. You can also opt for mineral water. If your effort is prolonged and intense, isotonic drinks can be beneficial to compensate for electrolytes lost through sweat. Avoid sugary and carbonated drinks, which can lead to gastrointestinal discomfort.

After exercise, recovery is crucial to allow your body to recover and rehydrate effectively. Within 30 minutes of physical activity, consume a recovery drink containing carbohydrates and proteins. This will help replenish your energy reserves and promote muscle rebuilding. A balanced diet, rich in nutrients, is also important for optimal recovery.

Simply listen to your body and adjust your hydration according to your individual needs. Environmental conditions, the intensity of your effort, and your personal sweat rate can influence your water needs. Learn to recognize the signs of dehydration, such as thirst, dry mouth, excessive fatigue, and decreased performance.

Which drinks should you prioritize?

For optimal hydration during exercise, it is wise to prioritize certain drinks that can offer additional benefits. Isotonic drinks, such as sports drinks, are distinguished by their composition rich in essential electrolytes such as

sodium, potassium, and calcium, thus helping to maintain your body's fluid and electrolyte balance. These drinks promote rapid fluid absorption, thereby improving your hydration level and preserving your performance. In addition, they provide a source of energy due to their carbohydrate content.

Coconut water-based drinks can also be beneficial due to their natural content of electrolytes and potassium. However, an alternative to consider is the use of Hydratis, a French company specializing in body hydration solutions.

Hydratis, your optimized hydration solution

Hydratis products offer a simple method to prevent dehydration or treat mild dehydration. Simply dissolve their effervescent tablets in a large glass of water and consume them. Each tablet provides your body with an adequate amount of electrolytes, thus compensating for losses caused by prolonged or intense exertion. This practical and effective approach helps you maintain optimal electrolyte balance while keeping your athletic performance at its best.

In summary, adequate hydration is the cornerstone of optimal athletic performance. By following these tips for hydration before, during, and after exercise, and by choosing appropriate drinks, you can enhance your ability to excel in your discipline while preserving your well-being. Remember that carefully listening to your body remains key to maintaining optimal fluid balance.
