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. 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. Thanks to our current insidious exposure to environmental pollutants, we may also require higher doses of nutrients than any of our predecessors.

Grounding: The Overlooked Benefit of Walking BarefootBy Dr. Mercola While still in the vast minority, an increasing number of people are joining the barefoot running trend, throwing their shoes to the wind and letting their feet run free, literally.In the modern world, it might sound "extreme" to give up your shoes, particularly when engaging in an activity as hard on your feet as running, but surrounding your feet with thick cushioning and stiff supports is actually the "new" trend, evolutionarily speaking. Humans Went Without Running Shoes for Millions of Years Writing in the journal Nature, Harvard researchers explained:1 "Humans have engaged in endurance running for millions of years, but the modern running shoe was not invented until the 1970s. Let's face it, your feet were designed to work without shoes. Shoes Alter Your Gait, but is This Good or Bad? Walking or running with shoes is quite a different experience than doing so without them. "Shoes affect the gait of children. Grounding: The Overlooked Benefit of Going Barefoot
VO2 max testHome > Fitness Testing > Tests > Aerobic Endurance > VO2 max The VO2max test is the criterion measure of aerobic power in athletes. Described here is the method to measure VO2max directly by indirect calorimetry. equipment required: Oxygen and carbon dioxide analyzers, ergometer on which workload may be modified, heart rate monitor (optional) and a stopwatch. Expired air may be collected and volume measured via Douglas bags or a Tissot tank, or measured by a pnuemotach or turbine ventilometer. procedure: Exercise is performed on an appropriate ergometer (treadmill, cycle, swim bench etc.).
SPEEDO LZR RACER - the world's fastest swimsuitRyan Lochte (USA) swims in the new Speedo LZR RACER Image Gallery (2 images) February 14, 2008 Following three years of research that included input from NASA, tests on more than 100 different fabrics and suit designs and body scans of more than 400 elite swimmers, Speedo has launched its most hydro-dynamically advanced - and fastest - swimsuit to date. The new suit has 10% less passive drag (meaning the drag present when the swimmer is gliding through the water after a dive or turn) than Speedo’s 2004 FASTSKIN FSII and 5% less passive drag than the FASTSKIN FS-PRO® - which has seen 21 swimmers break World Records since its release in March 2007. The specially engineered, highly flexible fabric called LZR PULSE™is ultrasonically welded so as to appear seamless. The LZR RACER’s unique design also provides swimmers with up to 5% more efficiency** in terms of their oxygen intake, enabling them to swim stronger for longer. About the Author Related Articles
In Focus: The Drug Testing ProcessIQ2 Debate: Is it OK for Athletes to Use Performance Enhancing Drugs? 50minWe’re right on the money with this IQ2 Debate. Is it OK for athletes to use performance enhancing drugs? The national drug body ASADA has been staring down the AFL and the NRL clubs in Melbourne and Sydney but up to this point there’s very little clarity about who took what and exactly what's illegal. There's defiance, anger, disbelief and a whole bunch of confusion as to what is performance enhancing. Is a performance enhancing drug one that helps mask the pain of an injury: helps you heal better, faster so you can get back on the field? Some punters might recall Laurie Connell and some notorious races in Perth way back in the 1980’s. But most of the public are still mystified by what’s legal and illegal and the media haven’t been all that enlightening. What’s wrong with a bit of chemical fine tuning of the athletic body? This IQ2 delivers moral outrage and some enlightenment and takes the debate further than anything published this far in the media.
Today Tonight Channel 7Dumbbell Exercises Complete with Animated DiagramsDumbbell exercises form an integral part of most strength training programs. They can be used to develop the various different elements of strength such as maximal strength, hypertrophy or muscle mass, explosive power and strength endurance. Why Free Weights? Free weights such as dumbbells activate smaller stabilizing muscle groups to control the exercise. Resistance machines on the other hand, tend to work muscle groups in very strict planes of movement. The downside of this very strict movement is that while some muscle groups will become significantly stronger, other, smaller muscles are neglected. The other advantage dumbbell exercises have over machines is that they fit around your body so the movement can be performed correctly. Athletes typically favor dumbbell exercises over machines as they can replicate sport-specific movements more accurately. Exercises By Muscle Group The dumbbell exercises below have been divided into the major muscle groups of the body. Flat Chest Presses 1.
Inspiring Our Children to Pursue STEM Through the Olympics | Vince BertramThe world's top athletes are competing at the 2014 Winter Olympic Games in Sochi, Russia. Their talents and abilities are truly amazing. Their preparation and dedication to their sport and their country are inspiring. No doubt, millions of children watch these athletes with similar dreams of achieving athletic excellence. But as I previously wrote, the likelihood that any child will reach the pinnacle of sports is slim. However, there is great opportunity for our athletically passionate students to continue their love of sports through their careers. From the half pipe to the ice rink and the snowboard to the speed skating suit, STEM experts make the 2014 Winter Games possible. The clothing worn by our athletes is just as intricately designed and manufactured. Engineers also play a vital role in the stadiums, arenas and venues in which our athletes perform. Consider Shaun White and the half pipe. STEM is the foundation of the 2014 Olympic Winter Games.

Fifa alarmed at widespread 'abuse' of painkillers4 June 2012Last updated at 21:24 ET By Matt McGrath Science reporter, BBC World Service Fifa medical officer Professor Jiri Dvorak talks about his research into the use of painkillers at recent World Cups Fifa's chief medical officer has said the "abuse" of painkillers is putting the careers and long-term health of international footballers in jeopardy. Dr Jiri Dvorak found that almost 40% of players at the 2010 World Cup were taking pain medication prior to every game. Ahead of Euro 2012, Dr Dvorak has urged football to wake up to the problem. He told the BBC that younger players are imitating the seniors and taking painkillers far too frequently. Fifa's medical team asked team doctors to provide a list of medications that players were taking ahead of each game in the 2010 World Cup. Previous surveys at international tournaments established that many players were using large numbers of pain killing and non steroidal anti inflammatory drugs (nsaids).
