A new study from the Center for Nutraceuticals at the University of Westminster shows that pink drinks can help you run faster and farther than clear drinks.
Researchers have found that a pink drink can increase exercise performance by 4.4% and may also increase a “ feel-good ” effect, which may make exercise easier.
The study, published in the journal Nutrition frontiers, is the first survey to assess the effect of drink color on physical performance and has the potential to open a new avenue for future research in sports drinks and exercise.
During the study, participants were asked to run on a treadmill for 30 minutes at a speed chosen by themselves, ensuring that their exertion rate remained constant. Throughout the exercise, they rinsed their mouths with a low-calorie, artificially sweetened pink drink or a clear drink that was also artificially sweetened and low in calories.
The two drinks were exactly the same and only differed in appearance – the researchers added food coloring to the pink drink to change the color.
Researchers chose pink because it is associated with perceived sweetness and therefore increases expectations for sugar and carbohydrate intake.
Previous studies have also shown that rinsing the mouth with carbohydrates can improve exercise performance by reducing the perceived intensity of exercise, so the researchers wanted to assess whether rinsing with a pink drink without a carbohydrate stimulus could achieve similar benefits from a potential placebo effect. .
The results show that participants walked an average of 212 meters farther with the pink drink while their average speed during the stress test also increased by 4.4 percent. The feelings of pleasure were also improved, which means that the participants found the race more enjoyable.
Future exploratory research is needed to find out whether the proposed placebo effect causes similar activation of reward areas of the brain that are commonly reported when rinsing the mouth with carbohydrates.
Commenting on the study, Dr Sanjoy Deb, corresponding author of the University of Westminster article, said: “The influence of color on athletic performance has sparked previous interest in its effect on sportsman’s kit to its impact on testosterone and muscle power.Likewise, the role of color in gastronomy has generated widespread interest, with research published on how visual cues or color can affect perception of subsequent flavor during consumption and drinking.
“The results of our study combine the art of gastronomy with performance nutrition, because adding a pink dye to an artificially sweetened solution not only improved the perception of sweetness, but also improved the sensations of pleasure. , the auto-selected running speed and the distance covered during a Class. “
