Gapminder: Unveiling the beauty of statistics for a fact based world view. Are sports drinks better than water when exercising? - Health & Wellbeing A: Sometimes, it depends on the individual situation Our expert: Profesor Louise Burke and Professor Clare Collins Published 21/07/2011 [Image source: iStockPhoto] Should you take a bottle of sports drink down to the gym when you do that hour's aerobics class? Well, whether you would benefit from consuming a sports drink depends on the events you are taking part in and your goals, says Professor Louise Burke of the Australian Institute of Sport. Sports drinks typically contain water and electrolytes (usually sodium and potassium) for rehydration and carbohydrates (as sugars) for energy. They were invented in the 60s to replenish fluid and provide extra fuel for intense sporting activity of a long duration (more than 90 minutes). "If you're in the gym pedalling to lose weight while you read a magazine, then you don't need a sports drink, just drink water," says Burke, who runs the nutrition program for the elite athletes at the institute. Do you need the carbs? Don't forget the sugar Use water:
DET NSW Sports Unit - DET NSW School Sports Unit The team shall consist of a maximum of twelve players who take the ground at any one time and any number of reserves. (Smaller sided games such as 6 or 9 a side are preferred for these age groups). There shall be no rucks or rovers. The team on the ground shall be divided into three groups (forwards, centre, backs), each group occupying a zone of the ground. Players should remain in their zone so that play does not become crowded. Players shall be rotated on the playing ground every quarter to experience the role of a forward, centre and backline player. The playing ground shall be approximately half standard senior size. A small ball up to midget size should be used for younger age groups. The game shall consist of 4 x 10 minute quarters. When the umpire considers that a player who has had a reasonable opportunity to dispose of the ball chooses to barge, fend off or chop past opponents a free kick shall be awarded to the nearest opponent.
Supplements Vitamin and mineral supplementation continues to be a contentious issue amongst health professionals. The common catch-cry of the medical community is that vitamins and minerals are adequately available from our food. It’s hard to appreciate the credibility of this advice, when it is delivered from a profession that receives negligible nutrition training. In Australia, this claim contrasts in stark hypocrisy against laws prescribing the mandatory fortification of bread with thiamine and salt with iodine. In addition, folic acid supplementation in pregnant women is a recommended requirement to protect an unborn child from developing spina bifida. The inconvenient reality is that food ‘ain’t what it used to be. Whilst sustainable agricultural practices such as biodynamic farming aim to restore our soils to health, we have considerable work to do before this option is universally adopted and available to everyone.

Sports Coach :: Climate control: acclimatising to the heat Author: Lisa Yates, Sports Dietitian, The Coaches Edge Issue:Volume 27 Number 1 Exercising in hot, humid conditions when the body is not accustomed to it can place the body under great stress. The demand for circulation to working muscles, which are producing heat, overtakes the need for blood flow to the skin to transport heat away from the body. What is heat acclimatisation? The benefits of heat acclimatisation have been known for many years (Robinson 1967). What are the benefits of being heat acclimatised? Acclimatisation produces: a lower heart rate at a given heat and exercise stress level better maintenance of core body temperature reduction in the sweating threshold increased distribution of active sweat glands increased sweat rate an increased sweating sensitivity to increasing core body temperature a reduction in the loss of water and electrolytes from the kidneys (Robinson 1967). How can coaches ‘climate control’ their athletes? Frequency of exercise Exercise duration References
