Should You Drink Sports Drinks Instead of Water?

If you ever watch sports, you have probably seen athletes sipping on brightly colored beverages before, during or after a competition.

These sports drinks are a big part of athletics and big business around the globe.

Many people believe that these drinks are the magic elixir to improve exercise performance, even if you are not an athlete.

However, others will tell you that this is just marketing and you should stick with water.

Water vs Sports Drinks

Water makes up the majority of your body weight and is critical for your body’s proper functioning (1Trusted Source).

In addition to losing water through urine, sweat and feces, your body is continually losing water through your skin and the air you exhale (2Trusted Source).

To replace these losses and promote good health and exercise performance, it’s often recommended to drink fluids regularly throughout the day (3Trusted Source4Trusted Source).

Although needs can vary, the recommended daily fluid intake is 91 ounces (2.7 liters) for adult women and 125 ounces (3.7 liters) for adult men (5).

The Main Ingredients in Sports Drinks

Water is the main ingredient in sports drinks, but they also contain other substances, including carbs and electrolytes, which are supposed to improve performance.

The carbs in these drinks are often in the form of sugars like glucose, sucrose and fructose, but they may also be found in other forms.

Typically, sports drinks are 6–8% carbohydrates. A 6% solution contains about 14 grams of carbs per 8 fluid ounces (240 ml) (6Trusted Source).

However, some sports drinks are low- or zero-carb in an effort to appeal to those who want water and electrolytes without extra calories.

Electrolytes, or minerals that have an electrical charge, are essential for your body’s normal operation (7).

The main electrolytes found in sports drinks are sodium and potassium (8Trusted Source).

Popular brands of sports drinks include Gatorade®, Powerade® and All Sport®, among others.

Although there are several different brands available, there is likely not a large difference in the effectiveness of the major sports drinks on the market (6Trusted Source).

While much research has been conducted on sports drinks, some people have questioned the validity of these studies.

Specifically, some have raised concerns about the relationship between the large companies that make sports drinks and the scientists performing the studies (9Trusted Source).


Sports drinks contain water and electrolytes such as sodium and potassium. Most also contain carbs. Several brands of sports drinks are available, but there are probably not major differences in their effects on the body.

Sports Drinks Can Benefit Athletes

The main components of sports drinks — water, carbs and electrolytes — are each important for different aspects of exercise performance.

Water and electrolytes are lost in sweat, and it’s important to replace them, particularly during long-duration exercise (10Trusted Source).

Your body stores carbs in your muscles and liver called glycogen, which is used for fuel during exercise (11Trusted Source).

Consuming carbs before or during exercise can help slow down how quickly your body runs out of its own carbohydrate stores (10Trusted Source).

Sports drinks are designed to provide these three important ingredients with the goal of improving exercise performance or recovery (8Trusted Source).

Many studies have examined the effects of sports drinks on exercise performance, and much of this research has been conducted in athletes.

Short-Duration Exercise

It’s not fully clear if sports drinks are beneficial for short-duration exercise.

One report examined nine studies of intense cycling or running lasting 30–60 minutes (6Trusted Source).

Six of the studies showed that sports drinks benefited exercise performance. However, all participants were trained athletes performing intense exercise.

One study in trained cyclists found that a sports drink improved performance by about 2% during one hour of intense cycling, compared to a placebo (12Trusted Source).

Despite these findings, there is not strong evidence to support the benefits of sports drinks for short-duration activities, such as jumping, sprinting and agility exercises (13Trusted Source).

Similarly, clear benefits have not been demonstrated for weight training (14Trusted Source15Trusted Source).

Team Sports and Intermittent Exercise

The usage of sports drinks is very common in team sports like soccer, basketball and football.

These sports involve intermittent activities, which alternate between intense exercise and rest.

Some research shows that ingesting carbohydrate drinks like sports drinks can reduce fatigue and improve performance in sports like soccer and rugby (13Trusted Source).

Other studies have examined cycling for periods of 1.5–4 hours with periodic rest.

One report found that 9 out of 12 studies using this type of exercise showed better performance when sports drinks were consumed, compared to a placebo (6Trusted Source).

Prolonged Continuous Exercise

Unlike intermittent exercise, continuous exercise is performed with no rest periods.

Many studies have examined the effects of carbohydrate beverages like sports drinks during continuous exercise lasting 1–4 hours or longer, such as running and cycling.

The majority of these studies show improvements in performance when consuming these beverages (6Trusted Source).

Likewise, athletes in team sports that are most similar to prolonged continuous exercise, such as soccer, are most likely to benefit from sports drinks (13Trusted Source).

These improvements may be due to the fact that sports drinks provide carbs for energy as your body’s stores get low and help prevent dehydration (10Trusted Source).

How Many Carbs?

Generally, the number of carbs that may be beneficial increases as the duration of exercise increases.

Research has shown that small amounts of carbs (fewer than 30 grams per hour) may improve exercise performance in events lasting 30–75 minutes (10Trusted Source).

It’s recommended to consume up to 30 grams per hour of carbs, or about 16 fluid ounces of a sports drink with 6% carbs, in sessions lasting 1–2 hours.

Sessions lasting 2–3 hours may benefit from more carbs — up to 60 grams per hour (10Trusted Source).

However, these recommendations are for continuous high-effort activity without rest. The same guidelines don’t apply to certain intermittent activities like weight training.


In athletes, sports drinks may improve performance in various types of exercise, with the clearest benefits being seen for prolonged exercise without rest. The number of carbs that may be beneficial increases as the duration of exercise increases.

They Are Unnecessary for Most People

There are several factors to consider when deciding whether sports drinks may benefit you.

Type and Intensity of Exercise

First, consider your exercise habits, as well as the duration and intensity of your training.

While sports drinks can benefit athletes who engage in long or intense training sessions, they are probably unnecessary for most gym-goers.

If you perform light-to-moderate exercise, such as walking or jogging, for less than 1 hour, you probably do not need to use sports drinks.

Similarly, if you only perform weight training, you probably do not need to use sports drinks, even if you spend over an hour at the gym.

Much of your time may be resting between sets, and weight training does not reduce your body’s carbohydrate stores as much as endurance exercise does (14Trusted Source).

If you do decide to use a sports drink, you should probably consume smaller amounts for exercise lasting less than an hour and no more than 30 grams of carbs for a session lasting 1–2 hours (10Trusted Source).

They May Affect Weight Loss

For those trying to maintain or lose weight, another important factor to consider is energy balance, or the balance between the number of calories you consume and burn.

If you want to lose weight, you need to burn more calories in a day than you consume.

If sports drinks are unnecessary for the type of exercise you do, consuming them provides you with unnecessary calories that could hinder your weight loss goals.

However, some research has shown that consuming sports drinks during exercises like running do not “undo” the calories used during exercise (16Trusted Source).

For example, a 150-pound (68-kg) person may burn about 240 calories when jogging for 30 minutes (17).

Consuming 12 fluid ounces (355 ml) of a common sports drink may provide about 20 grams of carbs and only 80 calories.

However, it’s important to realize that some activities may not burn many calories, even if they feel difficult.

For example, weight training may only burn around 120 calories in a 30-minute session if you weigh 150 pounds (68 kg) (18).

Think about whether the type and duration of the exercise you do requires a sports drink and be aware of how many calories you consume from these beverages.


Although sports drinks can improve the performance of athletes during several types of exercise, they are probably unnecessary for most people. If you choose to drink these beverages, it is important not to overconsume them.

Many Different Beverages Can Help You Stay Hydrated

Much of the marketing of sports drinks focuses on their ability to keep you hydrated by replacing water and electrolytes lost through sweat.

Staying Hydrated

How much you sweat can vary based on many factors, including how long and intensely you exercise, your training level and your environment.

The rate of sweating in humans may range from about 10 fluid ounces/hour (0.3 liters/hour) to 81 fluid ounces/hour (2.4 liters/hour) (19Trusted Source).

What’s more, it’s recommended that athletes do not lose more than 2–3% of their body weight through sweat during exercise (10Trusted Source).

However, it’s debated whether sports drinks are more effective than water at keeping you hydrated.

Other Options to Stay Hydrated

One study compared 13 different beverages, including sports drinks and water, to see how well they hydrated the body (20Trusted Source).

Researchers provided 33.8 fluid ounces (1 liter) of each of these drinks and collected urine over the next several hours.

They found that milk, orange juice and an oral rehydration solution provided the highest amount of hydration.

Oral rehydration solutions are specifically designed to cause fluid retention and contain higher levels of sodium and potassium than a normal sports drink.

An interesting finding from this study was that there was no difference in the hydrating ability of water, sports drinks, tea and cola.

In fact, some beverages that are typically considered to be dehydrating, such as coffee and beer, hydrated the body about as much as water.

In fact, other research has indicated that coffee can help keep you hydrated, contrary to popular belief (21Trusted Source).

It’s important to note that most drinks can contribute to your daily fluid requirements and help keep you hydrated.

This doesn’t mean that you should drink cola or beer during exercise, but it demonstrates that a wide variety of beverages can provide hydration throughout the day.

Enjoying Your Drink

Another factor to consider is that your enjoyment of certain beverages could affect how much you drink.

Research has shown that the flavor of sports drinks causes athletes to drink more than if they were consuming water alone (22Trusted Source23Trusted Source).

As a result, drinks that taste better may be beneficial for increasing fluid consumption in those possibly at risk of dehydration.


While sports drinks may help keep you hydrated, many other beverages can too. Water and sports drinks provide a similar amount of hydration, although the flavor of sports drinks may cause some individuals to drink more.

The Bottom Line

Sports drinks are very popular among athletes and recreational exercisers, but it’s debated whether they’re any better than plain water.

The main components of sports drinks are water, carbs and electrolytes.

Research supports their benefits in athletes and those performing long or intense exercise. The recommended amount varies based on the type of exercise.

However, most active individuals in the general population do not exercise intensely enough or long enough to need sports drinks.

Additionally, many beverages can hydrate your body just as effectively as sports drinks, including plain water.

If you choose to use sports drinks, be aware of their calorie contents.

Overall, sports drinks can benefit very active individuals and athletes, but they are not necessary for most people.
