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.

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
