At the end of a race,you'll often see runners reaching for bananas.Although people who only exercise at weekends might be more likely to reach for a sports drink,serious athletes know there are better choices.And a new study from Appalachian State University offers proof that bananas may be a better choice than sports drinks after exercise.
Researchers analyzed the blood of 20 competitive cyclists after they were given water and bananas,water only,or a 6 percent sugar drink（a sports drink）every 15 minutes during a 47-mile bike ride.The study found that the carbohydrates（碳水化合物） in bananas work as well as sports drinks to fuel athletes and help them recover.But the researchers found an additional benefit.Bananas also provide greater anti-inflammatory benefits than sports drinks.
"Consuming bananas with water during exercise has several advantages for athletes above those linked to regular sports drinks,"Dr David Nieman said in a statement. "Banana metabolites（代谢物）that increase in the blood have a similar effect to aspirin that inhibits（抑制）COX-2 activity.This makes bananas close to the perfect athletic food. "
"Although aspirin and other anti-inflammatory drugs（AIDs）help athletes with post exercise pain,they are often discouraged because they can cause cell damage," Nieman tells Men's Health. "For this reason,we tell athletes not to take them," he says. "To our pleasant surprise,we found something natural in bananas is working like these painkillers but without the risks. "
Sports drinks are still a choice,but Nieman and his team believe bananas offer more.
"There's no question that sports drinks work," he explains. "But bananas also have other nutrients - vitamin C，B6 and these unique metabolites - that you don't get with a sports drink. " Next up,the research team is looking at other fruits as exercise companions. "We're starting to look at blueberries,because we think with bananas they might work even better," Nieman says.
