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:
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

Making your kid play organized sports could cost them their creativity Youth sports are viewed as a rite of passage in a child’s development. If the clichés that permeate sports broadcasts and locker room speeches are to be believed, sports participation teaches children the value of hard work, builds character, and develops future leaders. While the validity of these claims are questionable, the fact remains that parents allow millions of children to participate in youth sports each year. Yet as a researcher and consultant who studies youth sports, I frequently speak with concerned parents. Youth sports have become a big business in the United States, and have taken on a much more professionalized form over the past decade. Childhood sports and adult creativity: a study In a study published earlier this fall in the Creativity Research Journal, some colleagues and I wrote an article that investigated the relationship between childhood leisure activities and creativity in young adults. What could account for such distal results? 1. 2.
Sports Medicine aged athletes Home > PDHPE > Options > Option 3 - Sports Medicine > Sports Medicine Key Messages There are many positive benefits of exercise for adults and aged athletes. Exercise duration, intensity and type need to be examined for suitability for this group. Medical conditions associated with ageing need to be considered when participating including: heart conditions fractures and bone density flexibility and joint mobility. Aged athletes may need to have medical clearances and should be aware of their options and limitations. There are many active adults and aged athletes who participate in competitive sport and are very successful. The Australian Government, in conjunction with Sports Medicine Australia, in 2005 produced a document entitled Choose Health: Be Active , a physical activity guide for older Australians. As a result of the ageing process, the ability to function efficiently decreases and more athletes may have a history of poorer health or poor health risk behaviours. Heart conditions

The Race to Nowhere In Youth Sports | Steve Nash Youth Basketball Blog By: John O’Sullivan Source: “My 4th grader tried to play basketball and soccer last year,” a mom recently told me as we sat around the dinner table after one of my speaking engagements. “It was a nightmare. “I know,” said another. So goes the all too common narrative for American youth these days, an adult driven, hyper competitive race to the top in both academics and athletics that serves the needs of the adults, but rarely the kids. The movie and article mentioned above, as well as the book The Overachievers: The Secret Lives of Driven Kids , highlight the dangerous path we have led our children down in academics. down a similar path in sports as well. The path is a race to nowhere, and it does not produce better athletes. The reason? We are so scared that if we do not have our child specialize, if we do not get the extra coaching, or give up our entire family life for youth sports, our child will get left behind.
Energy drinks: a trigger for heart attacks and stroke? When a 17-year-old girl, with a potentially life-threatening heart disorder, recently presented to me with an abnormally fast and irregular heart rhythm, I wondered how the natural history of her disease could so abruptly lead to a potentially fatal electrical rhythm disturbance. Until I questioned her more about the moments leading to the rhythm problem. Uncharacteristically, she had consumed a significant volume of a popular energy drink. Within an hour, she was in hospital receiving electrical shocks to her heart to bring it back to a normal rhythm. A mere coincidence, or did consuming an “energy drink” trigger her potentially fatal heart rhythm? Energy drink consumption has grown exponentially over the past five to ten years. The drinks are primarily targeted at the vulnerable youth and young adult market with aggressive advertising and marketing. So what is in energy drinks that could potentially trigger cardiac events? So what are the medical effects of energy drinks?
