Engaging in sports is an exhilarating adventure, but it requires special attention to our overall lifestyle. Among the pillars never to be neglected is hydration, a subject that becomes even more crucial when regularly engaging in physical activity. For vegetarian athletes, hydration can also be influenced by the contents of their plate, as fruits, vegetables, and other plant-based foods can provide a significant water intake. How can you stay hydrated throughout the day, during training sessions, and in competition periods? In this article, we will cover the fundamentals of sports hydration, focusing specifically on the situation of vegetarian athletes or those leaning towards a primarily plant-based diet.

Understanding the Importance of Hydration

Water is essential for life and all the biological functions of our body. It plays multiple roles, such as:

• Transporting nutrients and oxygen to cells
• Eliminating waste through urine and sweat
• Maintaining body temperature through sweating
• Lubricating joints and supporting tissue health

For an athlete, the need for fluids increases. During exertion, sweating helps regulate internal temperature. This mechanism is vital to avoid overheating, but it causes a substantial loss of water and electrolytes. Therefore, it is important, even essential, to compensate for both water and mineral losses (sodium, potassium, magnesium, etc.) to maintain good performance and prevent dehydration risks.

Risks of Insufficient Hydration

Insufficient hydration can negatively impact performance and recovery. Some symptoms indicating a lack of water include:

• Increased fatigue and decreased energy
• Headaches, dizziness, irritability
• Muscle cramps, energy slumps, difficulty maintaining effort
• Elevated heart rate, shorter breath
• Decreased concentration and coordination

For a vegetarian athlete, mastering hydration is as crucial as seeking a good nutritional balance. Focusing on daily water intake is a foundation, while liquid electrolyte and carbohydrate intake supports the body before, during, and after training.

Specific Needs of Vegetarian Athletes

Vegetarian diets can be very rich in nutrients: fibers, vitamins, antioxidants, minerals, and many other beneficial elements. Consequently, a vegetarian athlete can rely on culinary strategies to maximize natural hydration and quality nutrient intake. Fruits and vegetables, in particular, are valuable assets. They contain a high percentage of water and promote fluid balance in the body while providing essential vitamins.

Water Intake Mainly from Food

Some foods are particularly rich in water. Among them:

• Cucumber (about 95% water)
• Watermelon (over 90% water)
• Strawberry (about 90% water)
• Tomato (about 94% water)
• Zucchini (about 95% water)
• Green lettuce (up to 95% water)
• Celery (about 95% water)

Regularly consuming water-rich fruits and vegetables contributes to better basic hydration. In a standard day, a vegetarian can already rely on these intakes to meet part of their water needs. However, for an athlete who exerts more, drinking enough liquids in addition remains essential. Food alone cannot cover all water needs when energy expenditure, sweating, and mineral loss intensify.

Plant Proteins and Hydration

Plant proteins (legumes, tofu, seitan, tempeh, chickpeas, lentils, etc.) are often also a high source of fiber. Although they increase satiety, a high fiber content requires adequate hydration for optimal digestion. Fibers absorb water, which is beneficial for regulating intestinal transit but can increase the overall need for liquids.

The Importance of Electrolytes

Electrolytes, such as sodium, potassium, magnesium, or calcium, help maintain fluid balance and the stability of nerve and muscle functions. Some vegetarians may consume less sodium than most omnivores because they generally eat fewer processed foods. This can be beneficial for vascular health, but when engaging in intensive sports, significant amounts of sodium can be lost through sweat. Therefore, it is important not to neglect the importance of ensuring a sufficient daily intake of minerals, especially during and after exercise.

Basics of Optimal Hydration

It is generally recommended to drink at least 1.5 to 2 liters of water per day (about 6 to 8 glasses). For an athlete, this amount can be increased by 500 ml or even 1 liter or more, depending on the intensity and duration of the exercise, not forgetting temperature and humidity conditions. However, it is not about drinking excessively, as too much water can also disrupt mineral balance and lead to hyponatremia (too low sodium levels).

Before Exercise

Hydration does not start when you put on your sports shoes but throughout the day. It is advisable to drink regularly, in small amounts, before an exercise session, rather than “gorging” just before the effort begins. Drinking about 250-500 ml of water half an hour to an hour before training is a good guideline. This allows you to start the exercise with a correct hydration level.

During Exercise

Depending on the intensity of the activity and its duration, average fluid losses can be estimated at around 400 to 800 ml per hour of sport. Drinking 100 to 200 ml every 15 to 20 minutes helps gradually compensate for losses. For short efforts (less than an hour), water may suffice, especially if you have eaten a balanced meal before and can quickly refuel afterward. However, for longer efforts, it is preferable to add an isotonic drink containing electrolytes and possibly a small amount of carbohydrates.

After Exercise

The recovery phase is crucial for the athlete. Replenishing water and mineral reserves within 30 minutes after the activity is essential. Continuing to drink regularly in the hours following completes rehydration. This progression helps the body regain balance and contributes to better muscle regeneration, especially when combined with a quality plant protein intake.

Which Drinks to Favor?

Among drinks suitable for vegetarian athletes (and any other health-conscious practitioner), there is a wide range of choices. Water remains, of course, the essential foundation, but other options deserve mention:

1. Homemade Isotonic Drinks
   It is easy to prepare an isotonic drink at home. For example, you can mix:

   • 500 ml of water
   • 500 ml of diluted fruit juice (orange, grape, apple)
   • A pinch of salt
   • Optionally a hint of sugar (depending on the intensity of your effort and the desired level of dilution)

   This drink provides a balance of carbohydrates (from the juice), electrolytes (thanks to the salt), and water. It promotes rapid rehydration and maintenance of glycogen reserves.

2. Mineral Waters Rich in Bicarbonates
   So-called “bicarbonated” waters can be interesting if you experience acid-related discomfort from exercise (soreness, acidity). They contribute to acid-base balance and can help with recovery, especially during intense efforts.

3. Coconut Water
   Coconut water is considered by some as an almost isotonic drink. It contains potassium, sodium, calcium, and other minerals that play an essential role in rehydration. Its subtle and slightly sweet taste makes it pleasant after exertion, especially when well chilled.

4. Teas and Herbal Teas
   Green or black teas and certain herbal teas can be consumed in moderation. They contribute to hydration, even if they contain caffeine or tannins. It is advisable to limit their quantity to avoid increasing the diuretic effect too much.

5. Green or Fruity Smoothies
   Made from fresh fruits and vegetables, they can offer good water intake combined with essential nutrients. A smoothie made from spinach, banana, cucumber, water or coconut water, and a touch of lemon provides water, vitamins, fibers, and minerals. It’s a good recovery option after exertion, provided you add an appropriate plant protein source (for example, pea or hemp protein).

6. Diluted Fresh Fruit Juices
   100% fresh fruit juices, if too concentrated in sugar, can be diluted 50% with water to avoid an overly abrupt carbohydrate intake and a slowdown in rehydration. Nevertheless, a quality juice remains an interesting food to quickly replenish glycogen reserves, with vitamins and minerals: just watch the proportions and the time of day you consume it.

Daily Hydration: More Than Just a Matter of Drink

Beyond beverage consumption, a vegetarian athlete benefits from a varied diet rich in plants. As mentioned, water-rich vegetables and fruits ensure a basic intake. To support the body’s proper functioning, it is also important to avoid factors that can increase fluid loss or increase the risk of dehydration, such as:

• Excessive consumption of coffee or tea.
• Use of diuretics (medications or supplements).
• Extremely hot and/or humid weather conditions.
• Excessive sweating not compensated for.

The sensation of thirst is not always a reliable indicator. When you feel thirsty, you are already in a water deficit. For this reason, adopting hydration routines is essential if you regularly practice sports. Drinking a glass of water upon waking, a glass of water every hour or two, or setting reminders on your phone can help you remember to hydrate.

Recognizing Signs of Dehydration

Relying solely on thirst is insufficient. Some other indicators include:

1. Urine Color
   Very dark urine can be a sign of dehydration. Pale yellow to transparent urine is generally a sign that water intake is correct.

2. Dry or Sticky Mouth
   An obvious sign that the body lacks fluids.

3. General Fatigue and Confusion
   The effect of dehydration can be felt mentally and physically.

4. Muscle Cramps
   Muscles that contract painfully are sometimes a sign of electrolyte deficiency, often linked to dehydration.

5. Faster Heart Rate and Breathing
   When body fluids decrease, the heart must pump harder to send blood to muscles and vital organs.

If you experience any of these symptoms, it is urgent to drink. If the situation does not improve, or if you have significant dizziness, it is better to stop exercising, hydrate, and rest. Seek advice from a healthcare professional if in doubt.

Essential Minerals for a Vegetarian Athlete

Vegetarians, like all athletes, must pay attention to consuming enough of certain minerals. These help the body function optimally, particularly by regulating fluid balance:

• Sodium: essential for retaining water in the body. It is found in salt, but also in foods such as olives, miso, soy sauce, etc. Be careful not to overdo it if you already follow a salt-rich diet.
• Potassium: contributes to proper neuromuscular function. Present in bananas, sweet potatoes, spinach, white beans, and avocado.
• Magnesium: involved in muscle contraction and energy formation. Found in legumes, bananas, nuts (almonds, walnuts, etc.), and cocoa.
• Calcium: participates in bone strength and muscle contraction. Plant sources include leafy green vegetables, kale, broccoli, calcium-fortified tofu, and sesame seeds.

Practical Tips for Better Hydration

1. Plan Your Hydration: Try to include times to drink before, during, and after physical activity. Don’t just wait for thirst.
2. Vary the Pleasures: Alternate water, infusions, smoothies, coconut water, or herbal teas, ensuring to stay within reasonable proportions.
3. Monitor Your Activity Level: The more intensely and longer you train, the more your fluid and mineral needs increase.
4. Adapt Intake According to Weather: In hot weather, or in a humid climate, fluid intake must be increased, as sweating is more significant.
5. Learn to Read Labels: Some “sport” products can be very sugary or too rich in additives. If possible, make your own isotonic drinks to control the quality of the intake and sugar dosage.
6. Incorporate Water-Rich Foods: Salads, fruits, raw vegetables, smoothies, cold soups like gazpacho, etc.
7. Don’t Neglect Salt if You Sweat a Lot: In case of high heat or endurance training, adding a little salt to your drink or dishes can help maintain the sodium/water balance.
8. Use Reusable Bottles: Convenient for having your drink at hand and measuring the amount you drink.
9. Avoid Overconsumption of Stimulants: Drastically limit coffee, strong black tea, or energy drinks, as they can be diuretic.
10. Be Careful with Alcohol: Alcohol dehydrates by increasing urine production and can harm recovery.

Hydration: A Valuable Ally for Performance and Health

As a vegetarian athlete, you benefit from the significant water intake of your plant-based diet. However, hydration remains an essential aspect to monitor, whether it concerns your fluid or mineral balance. Remember:

• Water, electrolytes, and minerals must be regularly replenished during exertion.
• A good state of hydration before, during, and after physical activity optimizes your chances of performing well.
• Fruits, vegetables, and legumes can contribute to your water intake but should not replace your liquid intake, especially when it’s hot or the effort is prolonged.
• Awareness and planning are key. Scheduling your drink intake as you would schedule a sports training session helps you progress.

Conclusion

The topic of optimal hydration for vegetarian athletes combines the essential foundation of water with the diversity of a diet rich in plants. Fruits and vegetables already partially support water intake, but it remains necessary to drink enough, rely on strategies for electrolyte and mineral intake adapted to compensate for losses caused by sweating. Daily, incorporate hydration routines, vary liquid sources, and allow yourself to prepare your own recovery drinks to limit additives and precisely control nutritional intake. Well-planned, hydration remains an indispensable pillar, just like sports planning or overall nutritional balance. With a dose of anticipation and a bit of creativity, you will find suitable solutions to stay at the peak of your form while enjoying the benefits of a plant-based diet. By adopting good hydration habits, you will optimize not only your performance but also your overall health.
