Humans Could Run 40 mph, in Theory

There could be something to it. Humans only use like 10% of their brain or whatever. There's those anecdotes about people lifting cars off their kids in moments of extreme duress.

The world record for the 100 meter dash keeps going down. When Carl Lewis ran 27 mph doing the long jump, that was the absolute fastest anyone could run at the time. Now it's 28 mph. That's going to keep going up, and I guess when we hit 40 that's when it'll stop.

I think it's humans use 10% of their brain, at one time. Most of the brain is used, but the tasks are specialized, so it's unlikely that one would use their entire brain at once.

And if your entire brain is in use at once, I believe that's called "a seizure."

Humans could perhaps run as fast 40 mph, a new study suggests. Such a feat would leave in the dust the world's fastest runner, Usain Bolt, who has clocked nearly 28 mph in the 100-meter sprint.
The new findings come after researchers took a new look at the factors that limit human speed. Their conclusions? The top speed humans could reach may come down to how quickly muscles in the body can move.
Previous studies have suggested the main hindrance to speed is that our limbs can only take a certain amount of force when they strike the ground. This may not be the whole story, however.
"If one considers that elite sprinters can apply peak forces of 800 to 1,000 pounds with a single limb during each sprinting step, it's easy to believe that runners are probably operating at or near the force limits of their muscles and limbs," said Peter Weyand of Southern Methodist University, one of the study's authors.
But Weyand and colleagues found in treadmill tests that our limbs can handle a lot more force than what is applied during top-speed running.
What really holds us back
Their results showed the critical biological limit is imposed by time — specifically, the very brief periods of time available to apply force to the ground while sprinting. In elite sprinters, foot-ground contact times are less than one-tenth of a second, and peak ground forces occur within less than one-twentieth of that second for the first instant of foot-ground contact.
To figure out what limits how fast we can run, the researchers used a high-speed treadmill equipped to precisely measure the forces applied to its surface with each footfall. Study participants then ran on the treadmill using different gaits, including hopping, and running forward and backwards as fast as they possibly could.
The ground forces applied while hopping on one leg at top speed exceeded those applied during top-speed forward running by 30 percent or more. That suggests our limbs can handle greater forces than those found for two-legged running at top speeds.
And although top backward speed was substantially slower than top forward speed, as expected, the minimum periods of foot-ground contact at top backward and forward speeds were essentially identical. The fact that these two drastically different running styles had such similar intervals for foot-ground contact suggest that there is a physical limit to how fast your muscle fibers can work to get your feet off the ground, the researchers say.

Hardly. I max out GigE copying large video files average rate of 120-130MB/S sustained. 10Gbps Ethernet all the way.

We could fly, too, if we had wings. BRB writing article.

What a waste of a fancy treadmill.

Couldn't they have used it to figure out if the plane will take off??

a) The 10% of the brain is completely false, no scientific basis to it
b) Same is true about lifting cars, there's no scientifically proven cases of it.

Err, isn't GigE's speed 1000MegaBITS/s? Your capital MB implies Megabytes, and 1000mb is 125MB/s, ie, you reached capacity. (you might have bi directional gige, allowing you to go a bit over)

Or you were careless in your notation, and meant 120-130 megabits, which is well within the limits of even the slowest hard drives to sustain.

No that's what transfer rate I see in Win7 explorer, Netpersec shows 950+ Mbits/second. All fully switched network, procurve (hp), catalyst (Cisco) switches, INtel gigabit PCI-E server adapters, SAS SSD endpoints.

the current form we use for running is probably ideal for balance, and derives from the comfortable walk that most of us use. i think the article is suggesting that if one day there was a radical breakthrough in the way we do sprints, kind of like how the fosbury flop revolutionized how we did the high jump, humans could achieve a faster speed.
