In tennis, electrolyte supplementation is crucial for players' performance and health. Tennis is a high-intensity sport, and especially in hot weather, players sweat profusely, leading to the loss of electrolytes. This article will help athletes understand why choosing the right electrolyte drink is essential and provide some practical advice and tips to enhance performance during matches.
Why are electrolytes so important for tennis players?

Electrolytes are charged minerals, mainly including sodium, potassium, calcium, magnesium, and chloride. Their main functions in the body include:
A lack of electrolytes may cause fatigue, dehydration, or an inability to perform at your best during competitions. Therefore, choosing the right electrolyte drink is a detail that cannot be overlooked.
How to choose the most suitable electrolyte drink?
When choosing an electrolyte drink, the following points should be considered:
Choosing beverages that contain an appropriate amount of carbohydrates can provide energy for long-duration competitions. The ideal drink should contain 6% to 8% carbohydrates per serving, which can effectively enhance athletic performance and endurance.
Check the electrolyte content in the beverage, especially sodium and potassium. Sodium helps maintain fluid balance, while potassium contributes to normal muscle function. Some brands may indicate the specific amount of electrolytes, helping athletes make informed choices.
Choose a beverage flavor that suits you, as drinks that are too sour or too sweet may affect your appetite during the competition. The digestibility of the beverage is also important; you should not feel bloated or uncomfortable after drinking it.
If you prefer a healthier and more natural option, you can consider making your own electrolyte drink. By mixing water, lemon juice, a pinch of salt, and honey or sugar, you can create a simple electrolyte beverage.
In competitions or training, portability is an important factor when choosing beverages. Select products with packaging that is convenient to carry and not prone to leaking.
Techniques to Improve Competition Performance
To make the most of electrolyte drinks during competitions, here are five effective and practical tips:
23 hours before the competition, drink plenty of water first, and then about 30 minutes before the competition, drink approximately 200-300 milliliters of an electrolyte beverage. This ensures that your body is fully hydrated and helps prevent dehydration during the competition.
Actual application examples:
If the competition is scheduled for 10:00 a.m., it is recommended to start drinking water at 7:30 a.m. and have an electrolyte drink at 9:30 a.m. This can help maintain the body's fluid balance.
During the competition, you should regularly drink electrolyte beverages, especially during breaks between each round. You can set an alarm to remind yourself in order to maintain proper hydration.
Actual application examples:
At the end of each round (for example, after finishing 6 rounds), you can drink 100–150 milliliters of an electrolyte beverage, which can help your body stay energized.
Pay attention to your body's responses and understand the amount of water and electrolytes needed in different situations. Some athletes feel thirsty after intense exercise, while others may feel bloated.
Actual application examples:
If you find yourself frequently feeling thirsty, you may need to adjust the amount or frequency of your electrolyte drink intake to better suit your needs.
If the competition lasts for a long time, consider using electrolyte powder or energy gels as supplements. These products are convenient to carry and can quickly replenish the necessary energy and electrolytes.
Actual application examples:
During the competition, a portable electrolyte powder can be used once during each 15-minute interval break.
After the competition, it is still necessary to replenish electrolytes to promote muscle recovery. At this time, you can drink high-protein beverages combined with electrolytes to speed up muscle repair.
Actual application examples:
Consuming a drink containing electrolytes and protein within 30 minutes after the competition will help accelerate recovery.
Frequently Asked Questions
Electrolyte drinks contain minerals and are mainly used to replenish electrolytes lost during exercise, while pure water only provides hydration. During exercise, simply replenishing water may not be sufficient to meet the body's electrolyte needs.
During high-intensity exercise, especially in hot weather or during long competitions, it is recommended to use electrolyte drinks to prevent dehydration and maintain the body's electrolyte balance.
The optimal times to drink are 2 to 3 hours before the competition and during the competition itself, with the amount adjustable based on the intensity of the event. During training, electrolyte drinks can also be consumed in appropriate amounts according to the level of sweating.
Homemade electrolyte drinks are effective, but attention must be paid to the proportions. The right amount of salt, sugar, and juice can effectively replace commercial products. Using natural ingredients is not only healthy but also helps avoid the interference of artificial additives.
Some people may be allergic or intolerant to certain ingredients, so choices should be made based on personal experience. Compared to commercially available beverages, homemade drinks make it easier to control the ingredients, thereby reducing discomfort.
Electrolyte requirements are related to activity intensity, duration, and individual physiological conditions. For tennis players engaging in high-intensity exercise, it is recommended to consume approximately 500-700 milliliters of electrolyte drinks per hour, adjusting according to personal response and the amount of sweating.
Choosing the right electrolyte drink, combined with the above recommendations and tips, will help enhance tennis players' performance during matches and ensure adequate intake of fluids and electrolytes.
