This unique collection of original research and in-depth reviews examines the genes that make a champion, the physiology of elite athletes, limits to performance and how they might be overcome.
Excess body heat is a barrier to performance in many sports, and a novel study by Romain Meeusen et al.1 shows that both the neurotransmitter systems have an important impact on the control and perception of thermoregulation.
Rats whose dopaminergic and the noradrenergic reuptake was inhibited – by the anti-smoking aid Xyban – were able to exercise twenty minutes longer than usual in the sweltering heat and tolerated higher core body temperature.
What genes makes a champion, asked Alun Williams et al?2 They identify 23 individual genetic variations that enhance athletic performance — “If the optimum genetic combination existed in one person, world records like Paula Radcliffe’s would probably be shattered.”
Left to nature, the odds of anyone alive having all 23 variations is just 200,000:1. But what might the future hold for genetic manipulation and testing?
It’s no surprise that Marcus Amman et al. have shown that tiring out a leg muscle will subsequently reduce your performance in a 5km cycling time trial — but would you have guessed that it is ‘all in the mind’?3
It is not the muscle’s own temporary weakness that reduces performance, they find, but instead the brain places an unconscious ‘brake’ on the central motor drive to the limbs and therefore regulates exercise performance.
The Journal of Physiology’s Olympic Special Issue will be published on 1 January 2008.

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...
Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
