\"I'm happy to be done,\" Williams said from the International Space Station Sunday (Sept. 16) after she crossed the orbital finish line. \"It wasn't easy, and I'm sure everybody in California's very happy to be done too.\" <\/p>\n
Sunita Williamsis the U.S. commander of the Expedition 33 crew aboard the space station, which is orbiting Earth about 240 miles (386 km) overhead. She used exercise equipment, including a stationary bike, treadmill and strength-training machine specially formulated for weightlessness, to simulate thetriathlon experience in space. <\/p>\n
After \"swimming\" half a mile (0.8 km), biking 18 miles (29 km), and running 4 miles (6.4 km), Williams finished with a time of one hour, 48 minutes and 33 seconds, she reported. [Astronaut Runs Triathlon In Space | Video] <\/p>\n
The space station has its own treadmill and stationary bike, which use harnesses and straps in place of gravity to keep astronauts from floating away. To simulate the swimming portion of the race, Williams used what's called the Advanced Resistive Exercise Device (ARED) to do weightlifting and resistance exercises that approximate swimming in microgravity. <\/p>\n
\"It's critically important to understand human physiology and how to keep you strong on orbit,\" NASA's flight director in Mission Control said after Williams completed the triathlon, congratulating her on a race \"well done.\" <\/p>\n
Exercise is mandatory for all astronauts, because without it spaceflyers' muscles and bones would deteriorate in weightlessness. <\/p>\n<\/p>\n
