-How Fast Can a Human Go? (Time.com) "Usain Bolt may have just broken the human speed limit. Last week, he took two gold medals in the Olympic 100m, shattering his own world record with a time of 9.69 secs., and the 200m with a time of 19.3 secs., obliterating by two-hundredths of a second the long-standing world record Michael Johnson set at the Atlanta Games in 1996." 08-08
Bolt Lowers 100-Meter Mark to 9.58 (ESPN.com) "Usain Bolt crossed the finish line, saw his record-setting time on the clock and spread his arms as if he were soaring like a bird."
"The Jamaican shattered the world record again Sunday, running 100 meters in 9.58 seconds at the world championships to turn his much-anticipated race against Tyson Gay into a one-man show."
"That was 0.11 seconds faster than the mark he set last year at the Beijing Olympics -- the biggest improvement in the 100-meter record since electronic timing began in 1968." 08-09
Is Running Really Bad for the Knees? (Time.com) "The common wisdom is that regular running or vigorous sport-playing during youth subjects the joints to so much wear and tear that it increases a person's risk of developing osteoarthritis later in life. Studies have suggested that may be at least partly true: in one study of about 5,000 women published in 1999, researchers found that women who actively participated in heavy physical sports in their teenage years, or weight-bearing activities in middle age, had a higher than average risk of developing hip osteoarthritis by age 50."
"But over the past few years an emerging body of research has begun to show the opposite, especially when it comes to running. Not only is there no connection between running and arthritis, the new studies say, but running — and perhaps regular, vigorous exercise generally — may even help protect people from joint problems later on." 12-09
