China run India off the running map
It was Xue Bai who won the event, with a time of 2:25:15, and topped a strong performance from China, with as many as 4 Chinese in the top-13 results. It was quite a close finish, unlike the Mens marathon yesterday, with runner up Yoshimi Ozaki from Japan just 2:25:25 giving Xue a fight all the way.Aselefech Mergia from Ethiopia was third not too far behind in 2:25:32, and was infact leading T THE 40KM point of the race.
Interestingly, as many as 24 runners were bunched together at the half-way point, which was reached in 1:13:39, which included the other fancied runners Dire Tune and Bezunesh Bekele from Ethiopia. The much fancied Kara Goucher from the US was a dissapointing 10th placed in 2:27:48

Sex and Running....
***Extract from the article ***
BERLIN — As an 18-year-old runner from a village in South Africa received her gold medal in Olympic Stadium on Thursday night, activity away from the track had put her at the center of an international dispute: doctors here and in her home country were examining test results to determine whether she has too many male characteristics to compete as a woman.
The case of Caster Semenya, who has burst to prominence this season, touched off a debate over whether she should be allowed to keep her medal and, more broadly, how sports officials are supposed to discern the fuzzy biological line between male and female.
Medical experts said assigning sex was hardly as easy as sizing someone up visually. Even rigorous examinations can result in ambiguous findings. Some conditions that give women male characteristics can be discovered only through intrusive physical examinations, and others require genetic analysis.
“We can get quite philosophical here — what does it mean to be male or female?” said Dr. Richard Auchus, a specialist in disorders of sexual differentiation at the University of Texas Southwestern Medical Center at Dallas.
“For 99 percent of the population it’s easy to determine,” he added. “But one percent of the population have conditions that make it not so straightforward.”
Some of Semenya’s competitors in the 800 meters considered the issue straightforward after Semenya romped to a commanding victory at the world championships Wednesday. “Just look at her,” said Mariya Savinova of Russia, who finished fifth. Elisa Cusma of Italy, who was sixth, told Italian journalists: “These kind of people should not run with us. For me, she’s not a woman. She’s a man.”
But the matter is anything but simple. The testing done on Semenya, at the behest of the International Association of Athletics Federations, track and field’s world governing body, takes weeks to complete. It requires a physical medical evaluation, and includes reports from a gynecologist, an endocrinologist, a psychologist, an internal medicine specialist and an expert on gender. The effort, coordinated by Dr. Harold Adams, a South African on the I.A.A.F. medical panel, is being conducted at hospitals in Berlin and South Africa.
It is unclear what the exact threshold is, in the eyes of the I.A.A.F., for a female athlete being ineligible to compete as a woman......

Fast coincidence
"I want to be one of the best runners in the world," she says, "and winning an event like this means that's what you are."
The glory years of U.S. distance running started in 1969 with the arrival of Steve Prefontaine, the charismatic runner from the University of Oregon who won seven NCAA championships between 1970 and 1973 and was known for his all-out style and fearlessness on the track. "Pre" as he was known, would jump out to early leads, race as hard as possible and wear out opponents. Before he died in a car accident at 24, he set U.S. records in every event between 2,000 and 10,000 meters....
Meanwhile, African runners began winning everything in sight. Since 1983, runners from places like Kenya and Ethiopia have won 28 marathon medals in 18 major international events, while Americans have won four. Some went as far as to suggest the Africans weren't just more motivated—they might be genetically superior. A recent study by Swedish and South African scientists concluded that the biochemical phenotypes of many Africans' muscles are better suited for distance running than those of western Europeans.
Jim Estes, associate director of long-distance running programs for USA Track and Field, says many American runners of that era (himself included) hated the rigors of training—but the Africans never seemed to care. "Their threshold for pain just seemed much higher," he says.
Tom Ratcliffe, an agent for several Kenyan runners, says Africans "enjoy the battle" in endurance running while most Westerners "race with anxiety." He says his runners usually have no idea how many miles they run per week, or how fast. They just want to win.
Felix Limo, a Kenyan runner who has won the 2006 London and 2005 Chicago marathons, says U.S. runners rely too much on structure and scientific programs—the sorts of things described in those books in the 1970s. They fix their minds on certain speeds, he says, and aren't flexible enough.
"I don't need a mileage like the runners here," he says. "I can push myself."
One of the first Western runners to figure out the Africans was Great Britain's Paula Radcliffe, who has won eight major marathon events since 2000. She's got some structure to her training, but she's known more for her relentless attacking and competitiveness.
Ms. Radcliffe's emergence coincided with the 2001 founding of the Mammoth Track Club in Mammoth Lakes, Calif., whose mission is to advance the naturally aggressive "run first, ask questions later" style the Africans run with....

Getting enough Oxygen...
How Geese Get Enough Oxygen Flying Over Himalayas
For the bar-headed goose, migration is a high-altitude adventure. Spring and fall it flies between Central Asia and India, a route that takes it over the highest mountains in the world, the Himalayas. The bird has been known to reach altitudes of 30,000 feet.
At such heights, the air is so thin that there’s only about a quarter of the oxygen available at sea level. Yet the goose is able to sustain the level of O2 consumption — 10 to 20 times normal — needed for flapping flight.
How does it do this? In a paper in The Proceedings of the Royal Society B: Biological Sciences, Graham R. Scott, a doctoral student at the University of British Columbia, and colleagues show that it has a lot to do with the bird’s muscles.
Mr. Scott and his colleagues examined pectoral muscles from bar-headed geese and compared them to those from related species, like barnacle geese, that don’t fly at extreme altitudes. They found little difference among the birds in the amount and types of muscle fibers. But the bar-headed geese had more capillaries around the individual muscle cells, and within cells, more of the mitochondria — which use oxygen to supply energy to the cell — were nearer the cell membrane.“ The oxygen doesn’t have to diffuse as far,” Mr. Scott said.
He said the changes in the muscle cells probably evolved over a long period of time, perhaps as the Himalayas, one of the Earth’s youngest mountain chains, grew and the birds would have had to fly higher and higher.
