...which endurance runners rely. Slow-twitch muscle can contract for long periods of time with less fatigue, which helps some distance athletes run up to 60 mi. per day. Sprinters legs are genetically blessed with 70% fast-twitch and 30% slow-twitch muscles, which is what allows them to push off so fast and so powerfully, according to Scott Trappe, who heads the human performance laboratory at Indiana's Ball State University and has studied sprinters' muscles. But elite sprinters like Bolt may have even more of something that other world-class sprinters don't: superfast-twich muscles, which perform...
...another, says Daniel Lieberman, a professor of biological anthropology at Harvard University who studies how and why the human body looks and works as it does. What determines how fast people go is their stride length - a function of how long the legs are, how powerfully they push off into a stride and how far forward the body jumps - and their stride rate, which is how fast they can propel their legs forward. While great endurance runners, get their speed from long strides, sprinters get much of their speed from a fast stride rate - and from raw power. They...

The Iraqi Prime Minister had, for example, publicly opposed the surge of some 30,000 additional U.S. troops deployed in Iraq last year, but when they came anyway, al-Maliki's government muffled its dissent. That left many in the region and beyond questioning the extent of sovereign control exercised by the Iraqi government...
