Stamina all in the mind, says Noakes
Tim Noakes, a sports scientist at the University of Cape Town, and his team have found that the 71-year-old theory of fatigue by Nobel winner Archibald Hill is wrong. Hill claimed to have discovered that fatigue kicked in whenever muscles ran out of oxygen, glycogen or adenosine triphosphate, the substance that muscles use to store energy. But, about 20 years ago, Noakes set out to show that this was not the case.
