But the vast array of supplements available and lack of industry regulation make it difficult for the average person to make an informed choice about taking supplements. Now a report published in the online open access publication, Nutrition Journal suggests that even athletes, who should be well informed as to how to stay in peak physical condition, frequently take supplements without realising the potential benefits or side effects.
A research team, led by Andrea Petróczi of the School of Life Sciences at Kingston University, in South West London, UK re-analysed surveys filled in by high performance athletes, representing over thirty different sports, for the 'UK Sport 2005 Drug Free Survey'. Three-fifths of athletes questioned took nutritional supplements, but the reasons given for taking them did not generally match up to the supplements' actual effects. Not surprisingly, given this result, the team also found that relatively few supplement users appeared to be taking supplements because of medical advice.
The results are worrisome because high doses of some supplements may damage health and contaminated products may even cause athletes to fail drug-screening tests. To help remedy this, the article recommends that education about the use of nutritional supplements should become a required part of the accreditation process for all sport coaches. Indeed, previous research has shown that the more information athletes have on supplements, the less likely they are to take them.
"Incongruence regarding nutritional supplements and their effects is alarming," says Petróczi. "Athletes seem to take supplements without an understanding of the benefits they can offer, or their side effects, suggesting that supplements may be used by high performing athletes without a clear, coherent plan."

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
