(Wired, March 2007)A team of scientists from MIT took on the challenge, testing whether new advances in prosthetic technology gave athletes with artificial legs an advantage. The team put six elite sprinters with prosthetic legs on a fancy treadmill. They measured the ground reaction force of the sprinters legs and watched videos to examine leg swing swiss replica watches times. The article was published this week in Biology Letters.Though prosthetic legs are lighter than real legs, the athletes equipped with them did not have faster swing times. In addition, the sprinters tested measured 9 percent less ground reaction force on their prosthesis.
Mexicomountainside with a 20-plus sledding aficionados (who isn’t?),including a control group of five dedicated testers who rode each one.At least that was the plan. After we destroyed three of the sleds inshort succession, it became a free-for-all. In the replica Audemars Piguet watches midst of the mayhem,we did manage to take scores for durability, maneuverability, comfort,and, of course, speed. Afterwards we rated the sleds. Speed, naturally,was weighted most heavily.
Project Play, a 100% volunteer organization, is shipping 2,500 soccer balls to impoverished regions of Africa. In 2008, the organization shipped 2016 balls to Niger. With help from the Peace Corp, Irish born founder Mike Mitchell hopes to provide large replica Baume&Mercier watches amounts of recreational equipment to especially poor countries.
