Athletes and parents should be aware that with athletics, in particular running events, there will be fluid loss due to perspiration. Athletes can expect to lose at least 300ml of water every hour while competing. It is therefore, very important that athletes replace lost fluids by making sure that they drink during competition, and in particular on very hot days.
The best fluid replacement is water or very weak cordial or commercially available ‘sports drinks’. The sugar content in soft drinks is too high for them to be used as a means of fluid replacement. On hot days soft drinks, taken in large quantities over a short space of time, will inhibit absorption of water by the body from the gut and may lead to dehydration. Take soft drinks in moderation or leave them until after competition is completed. For this reason lollies should also be avoided before and during competition.
