Part I Reading Comprehension:
Will we ever run the 100m in nine seconds?
In 2008, at the Beijing Olympic games, Jamaican sprinter Usain Bolt ran the 100m in just 9.69 seconds,
setting a new world record. A year later, Bolt surpassed his own feat with an astonishing 9.58-second
run at the 2009 Berlin World Championships. He is arguably the fastest man in history but just how fast
could he possibly go?
That's a surprisingly difficult question to answer, and consulting the record books is of little help.
People are getting faster, but in an unpredictable way. From 1991 to 2007, eight athletes chipped 0.16
seconds off the record. Bolt did the same in just over a year.
Before 2008, mathematician Reza Noubary calculated that “the ultimate time for [the] 100 meter dash is
9.44 seconds.” Following Bolt's Beijing performance he said that the prediction “would probably go
down a bit.”
John Barrow from the University of Cambridge – another mathematician – has identified three ways in
which Bolt could improve his speed: being quicker off the mark; running with a strong tailwind; and
running at higher altitudes where thinner air would exert less drag on him. These tricks may work, but
they're also somewhat unsatisfying. We really want to know whether flexing muscles and bending joints
could send a sprinter over the finish line in 9 seconds, without relying on environmental providence.
To answer that we have to look at the physics of the sprinting leg. Peter Weyland from Southern
Methodist University has been studying the science of of running for decades.
Sprints are very short, so scientists can only make measurements in a limited window of time.
Weyand divides each cycle of a runners's leg into what happens when their foot is in the air, and what
happens when it's on the ground. The former is surprisingly irrelevant, Back in 2000, Weyland showed
that at top speed, every runner takes about a third of a second to pick their foot up and put it down again.
“It's the same from Usain Bolt to Grandma,” he says, She can't run as fast as him but at her top speed,
she's repositioning her foot at the same speed.
That third of a second in air – the swing time – is probably close to a biological limit. Weyand thinks that
there is very little people can do to improve it.
For most runners, speed is largely determined by how much force they can apply when their foot is on
the ground. They have two simple options for running faster: hit the ground harder, or exert the same
force over a longer period. Champion male sprinters can hit the ground with a force that is around 2.5
times their body weight. When Usain Bolt's foot lands it applies around 900 (400kg) of force for a few
milliseconds, and continues pushing for around 90 more.
In the 1990s, speed skaters started using a new type of ice skates. The blade of the skate was hinged to
the front of the boot rather than firmly fixed. As the skater pushed back, the new design kept their blades
in longer contact with the ice, allowing them to exert the same force over more time. Speed records
suddenly fell.
People have tried to duplicate the same effect with running shoes, but with little success. Technologies
that alter a runners gait tend to diminish the leg's overall performance.
One option remains for runners. Exert more force on the ground. Put simply, fast people hit the ground
more forcefully than slow people relative to their body weight. But we know very little about what
contributes to that force, and we are terrible at predicting it based on a runner's physique or movements.
Studies are underway to fill those gaps. Marcus Pandy and Tim Dorn used computer simulations of
sprinters to show the calf muscles, more than any others, determine the amount of force that runners
apply to the ground. At top speeds, the hip muscles become increasingly important, too.
