What benefits can coconut water provide an exerciser?

Coconut water, the clear liquid found in coconuts, is rich in sugars and amino acids, as well as calcium, magnesium, potassium, and sodium, important electrolytes lost to sweat during exercise.
These qualities make coconut water an attractive choice for replenishing your body after exercise.
Given all the nutrients you can gain for only 46 calories per 200 ml-glass, coconut water is generally a good choice for staying hydrated, and it may be better than sweetened energy drinks after a workout.

 

Some Athletes Swear By It

Professional tennis player John Isner credits coconut water with keeping him on his feet for his epic 11-hour marathon Wimbledon tennis win. “It is super hydrating and has kept me going in long matches and prevented me from cramping even in the hottest and most humid conditions,” Isner says.

He drinks a mixture of coconut water and water the night before a match in difficult heat conditions and routinely mixes a cocktail of coconut water and sea salt for on-court hydration and mixes it with protein powder for post-match recovery.  

Coconut water may be better at replacing lost fluids than a sports drink or water -- as long as you enjoy the taste. A study recently published in Medicine & Science in Sports & Exercise shows that coconut water replenishes body fluids as well as a sports drink and better than water but the athletes preferred the taste of the sports drinks.

Sports nutritionist Nancy Clark, MS, RD and author of Nancy Clarks Sports Nutrition Guidebook says coconut water won’t rehydrate the body unless you can drink plenty of it. If you enjoy the taste and can tolerate large amounts, it could help keep you hydrated.

A 2007 study shows coconut water enhanced with sodium was as good as drinking a commercial sports drink for post-exercise rehydration with better fluid tolerance. Another study reported that coconut water caused less nausea, fullness, and stomach upset and was easier to consume in large amounts during rehydration.

 

What Is Coconut Water?

Naturally refreshing, coconut water has a sweet, nutty taste. It contains easily digested carbohydrate in the form of sugar and electrolytes. Not to be confused with high-fat coconut milk or oil, coconut water is a clear liquid in the fruit’s center that is tapped from young, green coconuts.

It has fewer calories, less sodium, and more potassium than a sports drink. Ounce per ounce, most unflavored coconut water contains 5.45 calories, 1.3 grams sugar, 61 milligrams (mg) of potassium, and 5.45 mg of sodium compared to Gatorade, which has 6.25 calories, 1.75 grams of sugar, 3.75 mg of potassium, and 13.75 mg of sodium.

Better Than Some Sugary Drinks

Coconut water has less sugar than many sports drinks and much less sugar than sodas and some fruit juices. Plain coconut water could be a better choice for adults and kids looking for a beverage that is less sweet. But don’t overdo it, says Lillian Cheung, DSc, RD, of Harvard School of Public Health. “One 11-ounce container has 60 calories and if you drink several in one day, the calories can add up quickly," Cheung says.
