A new study led by the Centre for Nutraceuticals in the University of Westminster shows that pink drinks can help to make you run faster and further compared to clear drinks.
The researchers found that a pink drink can increase exercise performance by 4.4 per cent and can also increase a 'feel good' effect which can make exercise seem easier.
The study, published in the journal Frontiers in Nutrition, is the first investigation to assess the effect of drink colour on exercise performance and provides the potential to open a new avenue of future research in the field of sports drinks and exercise.
During the study participants were asked to run on a treadmill for 30 minutes at a self-selected speed ensuring their rate of exertion remained consistent. Throughout the exercise they rinsed their mouths with either a pink artificially sweetened drink that was low in calories or a clear drink which was also artificially sweetened and low in calories.
Both drinks were exactly the same and only differed in appearance - the researchers added food dye to the pink drink to change the colour.
