WHAT’S HOT!3. What type of carbohydrate is most likely in

the sports drink to provide quick energy?http://health.ninemsn.com.au/dietandnutrition/nutrition/693802/sports-drinks-the-real-facts

Sacrose, fruitose – sugar It is well known that consuming carbohydrate

can have performance benefits in a range of sporting events. Carbohydrate provides a fuel source for muscles and the brain, and contributes to the palatability of sports drinks. Ideally the carbohydrate concentration of a sports drink should not exceed 8%, or even be slightly less.

WHAT’S HOT!5. Suggest a health risk associated with high intake of

sodium?http://health.ninemsn.com.au/dietandnutrition/nutrition/693802/sports-drinks-the-real-facts

The sodium in sports drinks plays a valuable role in improving fluid absorption and the desire to drink. Sodium can also play a role in replacing the large salt losses that can occur in long events (e.g. ironman triathlons) or for salty sweaters. Sports drinks have a similar sodium content to foods such as milk, bread and breakfast cereal, but are much better tolerated during exercise.

You should always experiment with sports drinks in training before using them in competition. Not drinking enough sports drink, or drinking a lot in a short period of time, can cause gastrointestinal upset. Drink small amounts frequently to minimise problems.

WHAT’S HOT!6. Why is water essential when undertaking

sport?http://www.sportsdietitians.com.au/resources/upload/file/Sports%20Drinks.pdf
