Elite (0) ...competitors..... like the Jamaican Usain Bolt have regularly been clocked running at nearly 45 kilometres per hours. Such speed would have seemed (1) ...unbelievable... not so long ago. Scientists now suggest that humans can move (2) .....even faster.... faster than even that, perhaps as fast as 65 kilometres per hour
For years, it was assumed that simple muscle power determined human speed, but recent research suggest otherwise. The most important (3) ....limiting.... factor appears to be how quickly the muscles can contract and thus (4) ....reduce.... the time a runner's foot is in contact with the ground
Is our athletic ability inherited ? Researcher Alun Williams has (5) .....identified....... twenty - three inherited factors that influence sporting performance, such as the (6) ...efficient.... use of oxygen, and strength. As world population rises, predicts Williams, the (7) ....likelihood ..... of there being someone with the right genes for these twenty - three (24) ...characteristics .... will increase noticeably and thus faster runners are likely to emerge in future
