Runs real fast

I OTOH would have thought it was a matter of his stride length and its frequency.

When are people going to grow wheels?  Get with it evolution, wheels are awesome.  Maybe like a half track dog as a pet.

So this is about drag coefficients?  I might be able to help:

His "doctor" uses very hard to trace drugs.
 
2013-07-27 05:31:40 AM  
He's also really tall.

He takes about 10 less strides than everyone else to get to the finish line. That makes all the difference.

Only on flat terrain.

There are no straight lines in nature, thus wheels are a hindrance.

Dirtbikes have evolves over time.  Don't tell me you're some bible thumping idiot.  Check the body and tire styles.  The thin, bald tires gave way to fat, knobby tires.

And when he grips you in his metal claws, you can't get away, because Mr Bolt is very strong.
 
2013-07-27 08:34:08 AM  
I'll defer to the people who have actually done the math, but somehow it doesn't seem reasonable that 92% of the energy expended is used to overcome drag.

If that were the case, sprinter would all be small, tiny folks. And for the most part, they are well muscled and have developed their upper bodies. I would also think if that was the case you would see tight aerodynamic suits by now, and sprinters all seem to run in relatively loose clothing...in some cases even with their shoelaces untied!

Lost Thought 00: and talented doctors


It should be noted Bolt's coach is not among the cadre of Jamaican coaches whose athletes have been busted in the past. Indeed his coach was pretty much a nobody in Jamaican track until he came across Bolt. Keep in mind he's been working with Bolt since he was in his teens and had him running the 400. Bolt had to basically plead to run the 100 and 200 and his coach basically agreed on a lark and then it turns out Bolt was very fast.
 
2013-07-27 09:55:46 AM  
The trick is timing the fart just right to give you that extra boost over the finish line.
 
2013-07-27 10:06:38 AM  

mr_a: tight aerodynamic suits by now,


They've had those since the 80s. Turns out, they don't help at all.

Bolt's coach is this guy, not the guy listed in the article http://en.wikipedia.org/wiki/Glen_Mills Also Bolt was fast before there was any connection with Hernandez.

'Pretty much a nobody'.

No.

You should really watch the Usain Bolt documentary floating around.  His coach is Glen Mills, the guy who was the head of Jamaican Olympics team in the 80s, 90s, and 00s.

Gravity, for a start. Sprinters don't just move in the "X" direction, they bounce up and down. Also, sprinters are not free-wheeling, frictionless vehicles. They have to push off with their lead leg/foot, pick up their rear legs and move them forward, cushion their landing, and then repeat-all of which takes energy. They also swing their arms, attempting to generate forward momentum.

Just a quick thought- no doubt there are more. Even breathing while running at that speed probably takes a bit of energy.

Jamaican sprinters are being busted left and right lately, regardless of coach affiliation, and a lot of folks have been pointing fingers at the entire team as being dirty as hell for a while now.

Even if he isn't clean, it's not like all the other guys on the juice have ever come close to his performance.

Plenty of people run really fast. The secret to Bolt's success is running faster than all the other people in the same races.

A runner with good form keeps their center of balance in a horizontal line, no bouncing up and down.  Think of how the hurdlers lean so much when they go over the hurdle.  They also keep their center in front of their feet.  This is because running is actually the process of reapeatedly throwing yourself at the ground and failing.  Gravity helps you run, you don't need to work against it.

The pushing off and generating forward momentum is just working against drag, so that isn't another force.

I am sure they try to minimize vertical movement, but until humans grow wheels, there is no way their lets are not moving in the vertical direction. Likewise with their arms. That is all motion against gravity.

And I stand by my statement that if drag were the completely dominant factor, sprinters would all be small people. Instead they deliberately seek to build their upper bodies.
